Technical Field

The following generally relates to wireless communications, and more particularly, to oversubscription (overbooking) processing for multiple transceiver nodes.

Background

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems are capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems (e.g., Long Term Evolution (LTE) systems or LTE-advanced (LTE-a) systems, or LTE-a Pro systems) and fifth generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ techniques such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or discrete fourier transform spread OFDM (DFT-S-OFDM). A wireless multiple-access communication system may include multiple base stations or network access nodes that each simultaneously support communication for multiple communication devices, which may otherwise be referred to as User Equipment (UE).

In some cases, a UE may communicate with two or more transceiver nodes (or transmission/reception points (TRPs), base stations, etc.) on time/frequency resources. For example, the UE may receive control information from the transceiver node using various control resources configured (e.g., reserved (book)) for the UE. In some cases, each of the transceiver nodes may configure multiple control resources for the UE, which may exceed the decoding limits of the UE, e.g., may require an excessive number of blind decoding attempts and/or exceed the number of control channel elements that the UE may use for channel estimation. In one example, the UE may reach its decoding limit when decoding control information transmitted on the configured control resources from one transceiver node, thus preventing the UE from decoding any control information from other transceiver nodes. Thus, conventional oversubscription handling techniques may result in loss and/or degradation of communications between a UE and two or more transceiver nodes.

The described technology relates to improved methods, systems, devices and apparatus to support oversubscription processing for multiple transceiver nodes. In summary, the described technology provides a mechanism for a User Equipment (UE) to handle the following scenarios: wherein control resources corresponding to multiple transceiver nodes are configured for the UE, which typically exceeds the decoding limit of the UE. For example, a UE may be communicating with or at least receiving information from two or more transceiver nodes (e.g., transmission/reception points (TRPs), base stations, etc.). Each transceiver node may configure a plurality of control resources for the UE to receive control information. In some examples, each control resource may refer to a set of search spaces. The network node may assign a number (e.g., assign an Identifier (ID)) to each of a respective set or plurality of control resources of the control resources to support a decoding configuration of the UE. The UE may determine or otherwise identify a plurality of control resources corresponding to each associated transceiver node and select a decoding configuration to use based on the UE's decoding limitations. In some aspects, the decoding configuration may provide the following mechanisms: wherein the UE is capable of receiving/decoding control signals received on control resources corresponding to each of the one or more transceiver nodes. Accordingly, the UE may receive and decode control signals received on the control resources corresponding to each associated transceiver node according to the decoding configuration.

Detailed Description

A User Equipment (UE) may typically communicate with multiple transceiver nodes. A transceiver node may generally refer to a base station, a transmission/reception point (TRP), etc. In some examples, a TRP may be associated with one or more base stations and vice versa. Each transceiver node may configure resources for transmitting control information to the UE. However, the UE may be configured with a decoding limit that limits the amount of control resources that the UE may utilize. For example, the UE may be limited in the number of Blind Decoding (BD) attempts that the UE may perform during a time slot. In another example, a UE may be limited in the number of Control Channel Elements (CCEs) that the UE may use for channel estimation during a slot. This may result in an overbooking for the UE when the transceiver node configures more control resources than the UE may utilize during a particular time slot. While oversubscription may reduce network scheduling to have minimal complexity from a network perspective, conventional techniques for UEs to handle such oversubscription may be inefficient and/or ineffective. For example, a UE may utilize control resources from one transceiver node, but when the UE utilizes control resources from a second transceiver node, the UE may encounter its decoding limitations. This may result in the UE being unable to perform channel estimation, receive control information, etc. from the second transceiver node during the time slot.

Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the described technology generally provide mechanisms by which a UE may efficiently and effectively handle oversubscription situations in which the UE is configured with more control resources than the UE is able to utilize. For example, a UE may be configured with multiple control resources for each transceiver node. In some aspects, each of a plurality of control resources may be associated with a control signal (e.g., a Physical Downlink Control Channel (PDCCH) signal), which may include a set of search spaces. The UE may identify a plurality of control resources for different transceiver nodes and, based on the decoding limitations of the UE, may select a decoding configuration that supports aspects of the described techniques. In some aspects, the decoding configuration may include or otherwise be based on an Identifier (ID) for each of the plurality of control resources configured by the network for the respective transceiver node. Additionally or alternatively, the decoding configuration may include or otherwise be based on an ID for each transceiver node. In general, the decoding configuration may provide a mechanism by which the UE utilizes (e.g., in a balanced and efficient manner) the control resources corresponding to each transceiver node with which the UE is associated. Accordingly, the UE may decode control signals received on the control resources corresponding to each associated transceiver node according to the decoding configuration.

In some aspects, the decoding configuration may also be based on a control resource ID configured by the network to support aspects of the described techniques. As an example, the network may configure each transceiver node to use alternate IDs for its respective control resource. For example, the network may configure each transceiver node with an ID for its associated control resource based on how many transceiver nodes are transmitting control resources to the UE. As another example, IDs for transceiver nodes may be configured to enable a UE to decode control signals received on control resources corresponding to each associated transceiver node. For example, the UE may consider both the control resource ID and the transceiver node ID in decoding the control signal received on the control resource. In yet another example, the UE may split its decoding restrictions between the associated transceiver nodes.

Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow charts relating to oversubscription processing for multiple transceiver nodes.

Fig. 1 illustrates an example of a wireless communication system 100 that supports oversubscription processing for multiple transceiver nodes in accordance with aspects of the present disclosure. The wireless communication system 100 includes base stations 105, UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-advanced (LTE-a) network, an LTE-a Pro network, or a New Radio (NR) network. In some cases, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission critical) communications, low latency communications, or communications with low cost and low complexity devices.

The base station 105 may communicate wirelessly with the UE 115 via one or more base station antennas. The base stations 105 described herein may include or may be referred to by those skilled in the art as base station transceivers, wireless base stations, access points, wireless transceivers, node bs, evolved node bs (enbs), next generation node bs or gigabit node bs (any of which may be referred to as gnbs), home node bs, home evolved node bs, or some other suitable terminology. The wireless communication system 100 may include different types of base stations 105 (e.g., macro base stations or small cell base stations). The UE 115 described herein is capable of communicating with various types of base stations 105 and network devices, including macro enbs, small cell enbs, gnbs, relay base stations, and the like.

Each base station 105 may be associated with a particular geographic coverage area 110 in which communications with various UEs 115 are supported. Each base station 105 may provide communication coverage for a respective geographic coverage area 110 via a communication link 125, and the communication link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communication links 125 shown in the wireless communication system 100 may include: uplink transmissions from the UE 115 to the base station 105, or downlink transmissions from the base station 105 to the UE 115. Downlink transmissions may also be referred to as forward link transmissions, and uplink transmissions may also be referred to as reverse link transmissions.

The geographic coverage area 110 for a base station 105 can be divided into sectors that form only a portion of the geographic coverage area 110, and each sector can be associated with a cell. For example, each base station 105 may provide communication coverage for a macro cell, a small cell, a hot spot, or other type of cell, or various combinations thereof. In some examples, the base stations 105 may be mobile and, thus, provide communication coverage for a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, and the overlapping geographic coverage areas 110 associated with different technologies may be supported by the same base station 105 or different base stations 105. The wireless communication system 100 may include: for example, a heterogeneous LTE/LTE-A/LTE-A Pro or NR network, where different types of base stations 105 provide coverage for various geographic coverage areas 110.

The term "cell" refers to a logical communication entity used for communication with the base station 105 (e.g., on a carrier) and may be associated with an identifier (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID)) used to distinguish between neighbor cells operating via the same or different carriers. In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., Machine Type Communication (MTC), narrowband internet of things (NB-IoT), enhanced mobile broadband (eMBB), or other protocol types) that may provide access for different types of devices. In some cases, the term "cell" may refer to a portion (e.g., a sector) of geographic coverage area 110 over which a logical entity operates.

UEs 115 may be dispersed throughout the wireless communication system 100, and each UE 115 may be stationary or mobile. The UE 115 may also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a user equipment, or some other suitable terminology, where a "device" may also be referred to as a unit, station, terminal, or client. The UE 115 may also be a personal electronic device, such as a cellular telephone, a Personal Digital Assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, the UE 115 may also refer to a Wireless Local Loop (WLL) station, an internet of things (IoT) device, an internet of everything (IoE) device, or an MTC device, etc., which may be implemented in various items such as appliances, vehicles, meters, etc.

Some UEs 115 (e.g., MTC or IoT devices) may be low cost or low complexity devices and may provide automated communication between machines (e.g., communication via machine-to-machine (M2M)). M2M communication or MTC may refer to data communication techniques that allow devices to communicate with each other or base station 105 without human intervention. In some examples, M2M communications or MTC may include communications from devices that incorporate sensors or meters to measure or capture information and relay that information to a central server or application that may utilize the information or present the information to a human interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of machines. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, device monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service billing.

Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communications (e.g., a mode that supports unidirectional communication via transmission or reception, but does not support simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for the UE 115 include: enter a power-saving "deep sleep" mode when not engaged in active communication, or operate on a limited bandwidth (e.g., in accordance with narrowband communication). In some cases, the UE 115 may be designed to support critical functions (e.g., mission critical functions), and the wireless communication system 100 may be configured to provide ultra-reliable communication for these functions.

In some cases, the UE 115 may also be able to communicate directly with other UEs 115 (e.g., using peer-to-peer (P2P) or device-to-device (D2D) protocols). One or more UEs 115 in the group of UEs 115 communicating with D2D may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some cases, a group of UEs 115 communicating via D2D may utilize a one-to-many (1: M) system, where each UE 115 transmits to every other UE 115 in the group. In some cases, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving base stations 105.

The base stations 105 may communicate with the core network 130 and with each other. For example, the base stations 105 may interface with the core network 130 over backhaul links 132 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via the core network 130) over a backhaul link 134 (e.g., via an X2, Xn, or other interface).

The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an Evolved Packet Core (EPC) that may include at least one Mobility Management Entity (MME), at least one serving gateway (S-GW), and at least one Packet Data Network (PDN) gateway (P-GW). The MME may manage non-access stratum (e.g., control plane) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the EPC. User IP packets may be transported through the S-GW, which may itself be connected to the P-GW. The P-GW may provide IP address assignment as well as other functions. The P-GW may be connected to a network operator IP service. Operator IP services may include access to the internet, intranets, IP Multimedia Subsystem (IMS), or Packet Switched (PS) streaming services.

At least some of the network devices (e.g., base stations 105) may include subcomponents such as access network entities, which may be examples of Access Node Controllers (ANCs). Each access network entity may communicate with the UE 115 through a plurality of other access network transport entities (which may be referred to as radio heads, intelligent radio heads, or TRPs). In some configurations, the various functions of each access network entity or base station 105 may be distributed across various network devices (e.g., radio heads and access network controllers) or consolidated into a single network device (e.g., base station 105).

The wireless communication system 100 may operate using one or more frequency bands, which are typically in the range of 300MHz to 300 GHz. Generally, the region from 300MHz to 3GHz is referred to as the Ultra High Frequency (UHF) region or decimeter band, since the wavelength range is from about one decimeter to one meter in length. UHF waves may be blocked or redirected by building and environmental features. However, the waves may penetrate the structure sufficiently for the macro cell to provide service to the UE 115 located indoors. UHF-wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100km) compared to transmission of smaller frequencies and longer wavelengths using the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz.

The wireless communication system 100 may also operate in the ultra-high frequency (SHF) region using a frequency band from 3GHz to 30GHz, which is also referred to as a centimeter band. SHF areas include frequency bands, such as the 5GHz industrial, scientific, and medical (ISM) band, which can be used opportunistically by devices that can tolerate interference from other users.

The wireless communication system 100 may also operate in the Extremely High Frequency (EHF) region of the spectrum, e.g., from 30GHz to 300GHz (also referred to as the millimeter-wave band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antenna of the respective device may be even smaller and more compact than the UHF antenna. In some cases, this may facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may suffer from greater atmospheric attenuation and shorter transmission distances than SHF or UHF transmissions. Transmissions across the use of one or more different frequency regions may employ the techniques disclosed herein, and the designated use of frequency bands across these frequency regions may differ due to country or regulatory bodies.

In some cases, the wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ Licensed Assisted Access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (e.g., the 5GHz ISM band). When operating in the unlicensed radio frequency spectrum band, wireless devices (e.g., base stations 105 and UEs 115) may employ a listen-before-talk (LBT) procedure to ensure that frequency channels are free before transmitting data. In some cases, operation in the unlicensed band may be based on CA configurations in conjunction with CCs operating in the licensed band (e.g., LAA). Operations in the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in the unlicensed spectrum may be based on Frequency Division Duplexing (FDD), Time Division Duplexing (TDD), or a combination of both.

In some examples, a base station 105 or UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. For example, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., base station 105) and a receiving device (e.g., UE 115), where the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communication may employ multipath signal propagation to improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers, which may be referred to as spatial multiplexing. For example, a transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Likewise, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams. Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques may include single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., base station 105 or UE 115) to shape or steer an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by: signals transmitted via the antenna elements of the antenna array are combined such that signals propagating in a particular orientation with respect to the antenna array undergo constructive interference, while other signals undergo destructive interference. The adjustment of the signal transmitted via the antenna element may comprise: a transmitting device or a receiving device applies some amplitude and phase offset to signals carried via each of the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a set of beamforming weights associated with a particular orientation (e.g., with respect to an antenna array of a transmitting device or a receiving device, or with respect to some other orientation).

In one example, the base station 105 may use multiple antennas or antenna arrays for beamforming operations for directional communication with the UE 115. For example, the base station 105 may transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions, which may include: signals are transmitted according to different sets of beamforming weights associated with different transmission directions. The transmissions in the different beam directions may be used (e.g., by the base station 105 or by a receiving device such as the UE 115) to identify beam directions for subsequent transmission and/or reception by the base station 105. Some signals (e.g., data signals associated with a particular receiving device) may be transmitted by the base station 105 in a single beam direction (e.g., a direction associated with a receiving device such as the UE 115). In some examples, a beam direction associated with a transmission along a single beam direction may be determined based at least in part on signals transmitted in different beam directions. For example, the UE 115 may receive one or more of the signals transmitted by the base station 105 in different directions, and the UE 115 may report to the base station 105 an indication of the signal received by the UE 115 that has the highest signal quality or otherwise acceptable signal quality. Although the techniques are described with reference to signals transmitted by the base station 105 in one or more directions, the UE 115 may use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying beam directions for subsequent transmission or reception by the UE 115), or transmitting signals in a single direction (e.g., for transmitting data to a receiving device).

When receiving various signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) from the base station 105, a receiving device (e.g., UE 115, which may be an example of a mmW receiving device) may attempt multiple receive beams. For example, the receiving device may attempt multiple receive directions by receiving via different antenna sub-arrays, by processing received signals according to different antenna sub-arrays, by receiving according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of an antenna array, or by processing received signals according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of an antenna array (any of the above operations may be referred to as "listening" according to different receive beams or receive directions). In some examples, a receiving device may use a single receive beam to receive along a single beam direction (e.g., when receiving data signals). The single receive beam may be aligned in a beam direction determined based at least in part on listening from different receive beam directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio, or otherwise acceptable signal quality based at least in part on listening from multiple beam directions).

In some cases, the antennas of a base station 105 or UE 115 may be located within one or more antenna arrays that may support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some cases, the antennas or antenna arrays associated with the base station 105 may be located at different geographic locations. The base station 105 may have an antenna array with multiple rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with the UEs 115. Likewise, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations.

In some cases, the wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communications at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. In some cases, the Radio Link Control (RLC) layer may perform packet segmentation and reassembly to communicate on logical channels. A Medium Access Control (MAC) layer may perform priority processing and multiplexing of logical channels to transport channels. The MAC layer may also use Hybrid Automatic Retransmission (HARQ) to provide retransmissions at the MAC layer to improve link efficiency. In the control plane, a Radio Resource Control (RRC) protocol layer may provide for the establishment, configuration, and maintenance of an RRC connection between the UE 115 and the base station 105 or core network 130 that supports radio bearers for user plane data. At the Physical (PHY) layer, transport channels may be mapped to physical channels.

In some cases, the UE 115 and the base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. HARQ feedback is a technique that increases the likelihood that data will be received correctly on the communication link 125. HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), Forward Error Correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., signal and noise conditions). In some cases, the wireless device may support HARQ feedback for the same slot, where the device may provide HARQ feedback for data received in a previous symbol in the slot in a particular slot. In other cases, the device may provide HARQ feedback in subsequent time slots or according to some other time interval.

May be in basic time units (which may for example refer to T)_sA sampling period of 1/30,720,000 seconds) to represent the time interval in LTE or NR. The time intervals of the communication resources may be organized according to radio frames each having a duration of 10 milliseconds (ms), where the frame period may be denoted as T_f＝307,200T_s. The radio frames may be identified by a System Frame Number (SFN) ranging from 0 to 1023. Each frame may include 10 subframes numbered from 0 to 9, and each subframe may have a duration of 1 ms. The sub-frame may be further divided into 2 slots, each having a duration of 0.5ms, and each slot may contain 6 or 7 modulation symbol periods (e.g., depending on the length of the cyclic prefix added in front of each symbol period). Each symbol period may contain 2048 sample periods, excluding the cyclic prefix. In some cases, a subframe may be the smallest scheduling unit of the wireless communication system 100 and may be referred to asTransmission Time Interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 may be shorter than a subframe or may be dynamically selected (e.g., in a burst of shortened ttis (sTTI) or in a selected component carrier using sTTI).

In some wireless communication systems, a slot may be further divided into a plurality of minislots comprising one or more symbols. In some examples, the symbol of the mini-slot or the mini-slot may be the minimum scheduling unit. Each symbol may vary in duration depending on, for example, the subcarrier spacing or frequency band of operation. Further, some wireless communication systems may implement timeslot aggregation, where multiple timeslots or minislots are aggregated together and used for communication between the UE 115 and the base station 105.

The term "carrier" refers to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication over the communication link 125. For example, the carrier of the communication link 125 may include a portion of the radio frequency spectrum band that operates according to physical layer channels for a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. The carriers may be associated with predefined frequency channels (e.g., E-UTRA absolute radio frequency channel number (EARFCN)) and may be placed according to a channel grid for discovery by UEs 115. The carriers may be downlink or uplink (e.g., in FDD mode), or may be configured to carry downlink and uplink communications (e.g., in TDD mode). In some examples, the signal waveform transmitted on a carrier may be composed of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as OFDM or DFT-s-OFDM).

The organization of the carriers may be different for different radio access technologies (e.g., LTE-A, LTE-A Pro, NR, etc.). For example, communications over carriers may be organized according to TTIs or slots, each of which may include user data as well as control information or signaling to support decoding of the user data. The carriers may also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling that coordinates operation for the carriers. In some examples (e.g., in a carrier aggregation configuration), a carrier may also have control signaling to acquire signaling or coordinate operations for other carriers.

The physical channels may be multiplexed on the carriers according to various techniques. For example, physical control channels and physical data channels may be multiplexed on a downlink carrier using Time Division Multiplexing (TDM) techniques, Frequency Division Multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. In some examples, the control information sent in the physical control channel may be distributed in a cascaded manner between different control regions (e.g., between a common control region or common search space and one or more UE-specific control regions or UE-specific search spaces).

The carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or "system bandwidth" of the wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of predetermined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80MHz) of the carrier for the particular wireless access technology. In some examples, each served UE 115 may be configured to operate over part or all of the carrier bandwidth. In other examples, some UEs 115 may be configured for operation using a narrowband protocol type associated with a predefined portion or range within a carrier (e.g., a set of subcarriers or RBs) (e.g., an "in-band" deployment of the narrowband protocol type).

In a system employing MCM technology, a resource element may consist of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme). Thus, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate may be for the UE 115. In a MIMO system, wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers), and the use of multiple spatial layers may further increase the data rate for communication with the UE 115.

Devices of the wireless communication system 100 (e.g., base stations 105 or UEs 115) may have a hardware configuration that supports communication over a particular carrier bandwidth or may be configurable to support communication over one carrier bandwidth of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include base stations 105 and/or UEs that may be 105 and/or UEs 115 capable of supporting simultaneous communication via carriers associated with more than one different carrier bandwidth.

The wireless communication system 100 may support communication with UEs 115 over multiple cells or carriers (a feature that may be referred to as Carrier Aggregation (CA) or multi-carrier operation). According to a carrier aggregation configuration, a UE 115 may be configured with multiple downlink CCs and one or more uplink CCs. Carrier aggregation may be used with both FDD and TDD component carriers.

In some cases, the wireless communication system 100 may use an enhanced component carrier (eCC). An eCC may be characterized by one or more features, including: a wider carrier or frequency channel bandwidth, a shorter symbol duration, a shorter TTI duration, or a modified control channel configuration. In some cases, an eCC may be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have suboptimal or undesirable backhaul links). An eCC may also be configured for unlicensed spectrum or shared spectrum (e.g., where more than one operator is allowed to use the spectrum). An eCC featuring a wide carrier bandwidth may include one or more segments that may be used by UEs 115 that cannot monitor the entire carrier bandwidth or are otherwise configured to use a limited carrier bandwidth (e.g., to conserve power).

In some cases, an eCC may use a different symbol duration than other CCs, which may include using a reduced symbol duration compared to the symbol durations of the other CCs. Shorter symbol durations may be associated with increased spacing between adjacent subcarriers. A device using an eCC, such as a UE 115 or a base station 105, may transmit a wideband signal (e.g., according to a frequency channel or carrier bandwidth of 20MHz, 40MHz, 60MHz, 80MHz, etc.) with a reduced symbol duration (e.g., 16.67 microseconds). A TTI in an eCC may consist of one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in a TTI) may be variable.

Wireless communication systems, such as NR systems, may utilize any combination of licensed, shared, and unlicensed frequency bands, and the like. Flexibility in eCC symbol duration and subcarrier spacing may allow eCC to be used across multiple spectra. In some examples, NR sharing spectrum may increase spectral utilization and spectral efficiency, particularly through dynamic vertical (e.g., across frequency domains) and horizontal (e.g., across time domains) sharing of resources.

In some aspects, the UE 115 may identify a first plurality of control resources associated with a first transceiver node and a second plurality of control resources associated with a second transceiver node. The UE 115 may select a decoding configuration to use for decoding one or more control signals received on control resources from the first plurality of control resources and one or more control signals received on control resources from the second plurality of control resources based at least in part on a decoding restriction of the UE 115. The UE 115 may decode control signals received on control resources from the first plurality of control resources and the second plurality of control resources according to a decoding configuration.

In some aspects, the base station 105 may identify a plurality of control resources configured for the UE 115. The base station 105 may configure an identifier for each of the plurality of resources based at least in part on a number of transceiver nodes transmitting control resources to the UE 115. The base station 105 may transmit a plurality of control signals to the UE 115 using a control resource of a plurality of control resources, each control resource being transmitted in an order corresponding to the identifier.

Fig. 2 illustrates an example of a wireless communication system 200 that supports oversubscription processing for multiple transceiver nodes in accordance with aspects of the present disclosure. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. The wireless communication system 200 may include a plurality of transceiver nodes 105 (of which two transceiver nodes 105-a and 105-b are shown by way of example only) and a UE 115-a, which transceiver nodes 105 and UE 115-a may be examples of corresponding devices described herein.

In some aspects, each transceiver node 105 may be an example of a base station, TRP, AP, or the like. In some examples, a base station may monitor, manage, control, or otherwise associate with multiple TRPs. In some examples, a base station may monitor, manage, control, or otherwise associate with a single TRP. In some examples, such as in a carrier aggregation scenario, one transceiver node 105 may be considered a serving transceiver node while another transceiver node 105 may be considered a secondary transceiver node.

In some aspects, the network may allocate or otherwise configure a plurality of control resources for each transceiver node 105 for the UE 115-a. In some aspects, each control resource may include a PDCCH candidate, such as a search space set, which may also be referred to as an SS set. In general, the SS set may include basic elements of PDCCH configuration for providing information such as: on which symbols in the slot PDCCH candidates are transmitted, how many PDCCH candidates can be transmitted in these symbols, which CCEs are used to carry PDCCH candidates, etc. In general, the control resources may be used to communicate control information between the respective transceiver node 105 and the UE 115-a and/or by the UE 115-a to perform channel estimation.

In some examples, the network may collectively overboost control resources for UE 115-a. Oversubscription may refer to the network configuring PDCCH candidates (e.g., via multiple transceiver nodes 105) for UE 115-a that result in the number of BDs required or the number of CCEs used for channel estimation exceeding the corresponding decoding limit of UE 115-a. For example, two PDCCH processing restrictions may be configured for UE 115-a. The first PDCCH processing restriction may include the maximum number of BDs that the UE 115-a may perform per slot. The second PDCCH limit may include the maximum number of CCEs that the UE 115-a uses to perform channel estimation per slot. The decoding restriction of the UE 115-a may refer to a BD restriction, a CCE restriction, or a combination of a BD restriction and a CCE restriction. In some aspects, the UE 115-a may decode only a portion of the configured PDCCH candidates (e.g., control signals received on control resources) for which neither the required number of BDs nor the number of CCEs used for channel estimation exceed the corresponding decoding limit in the slot. Overbooking is useful because it makes network scheduling for multiple PDCCH configurations more efficient with manageable complexity.

However, conventional oversubscription processing techniques are inefficient and often ineffective, which results in wasted resources, excessive power consumption at the UE 115-a, and/or loss of communication between the UE 115-a and one or more of the associated transceiver nodes 105. In some aspects, oversubscription may not be allowed for Common Search Spaces (CSS), e.g., neither the total number of BDs required nor the total number of CCEs used for channel estimation exceed the corresponding decoding limits for all configured CSS sets in a slot. Accordingly, in the conventional art, the first step of the oversubscription process is for the UE 115-a to count the number of BDs and CCEs of all CSS sets configured in a slot and remove it from the corresponding BD and/or CCE limit (e.g., the decoding limit of the UE 115-a).

However, for each configured UE-specific search space (USS) set (from the USS set with the lowest ID to the USS set with the highest ID), the UE 115-a counts the total number of BDs and CCEs used to decode that USS set and all SS sets that have been counted (including CSS and USS sets), and compares the count to the corresponding BD and CCE limits (e.g., decoding limits). If a PDCCH candidate in a USS set cannot be fully decoded without exceeding any limit, the PDCCH candidates in that USS set and in all subsequent USS sets are not decoded. Thus, the conventional oversubscription process prioritizes PDCCH candidates for the lower ID SS set over PDCCH candidates for the higher ID SS set.

In one non-limiting example of such conventional techniques, the UE 115-a may be configured with four USS sets in a slot, where decoding of PDCCH candidates for each USS set consumes eight BDs. After counting the PDCCH candidates of the CSS set, the remaining budget for BDs in the slot is 20. According to the conventional oversubscription process based on BD restrictions, only two USS sets with the two lowest USS set IDs are processed. If the third USS set is also processed, the number of BDs is 24 (which is greater than 20) and therefore exceeds the decoding limit of the UE 115-a. In some aspects, the decoding constraints may not include the number of CCEs for all configured SS sets. In other examples, the decoding restrictions may include both BD restrictions and CCE restrictions that are met by the set of SSs processed by the UE 115-a. In some examples, such as in mmW networks, each set of SSs may be associated with a single beam, and the UE 115-a may communicate with one transceiver node 105 through one beam at a time, each decoded set of SSs may be associated with only a single transceiver node 105.

Aspects of the present disclosure provide various techniques to improve oversubscription processing. In broad terms, the described techniques generally ensure that the UE 115-a assigns its decoding restrictions in such a way that: ensuring that the UE 115-a is able to decode control signals received on the control resources corresponding to each associated transceiver node 105. The described techniques may be based on the ID of the configured control resource, the ID associated with each transceiver node 105, and/or based on the number of transceiver nodes 105 configuring the control resource for UE 115-a.

For example, the network may allocate or otherwise configure transceiver node 105 with a plurality of control resources for UE 115-a (e.g., a first plurality of control resources 205-a for transceiver node 105-a and a second plurality of control resources 205-b for transceiver node 105-b). Each transceiver node 105 is capable of transmitting control signals (e.g., PDCCH information) corresponding to that transceiver node 105 to the UE 115-a on a corresponding plurality of control resources 205. In some examples, a transceiver node 105 may be capable of transmitting a control signal associated with another transceiver node 105. In some aspects, each control resource 205 configured by the network for a corresponding transceiver node 105 may have an associated ID. The network of transceiver nodes 105 may configure the UE 115-a with multiple sets of control resources (e.g., multiple control resources) per time slot for each serving cell.

In some aspects, the UE 115-a may identify or otherwise select a decoding configuration to be used for decoding control signals received on the control resources 205. Broadly speaking, the decoding configuration may use various techniques (alone or in any combination) to ensure that the UE 115-a decodes some or all of the control signals received on the control resources 205 corresponding to the transceiver nodes 105-a and 105-b. Although two transceiver nodes 105 are shown in fig. 2, it is to be understood that the described techniques may be used for any number of transceiver nodes associated with UE 115-a. Further, it is to be further understood that in some examples, the network may configure a transceiver node 105 (e.g., transceiver node 105-a) to transmit control signals to the UE 115-a using control resources associated with another transceiver node (e.g., transceiver node 105-b), and vice versa.

In one example, the decoding configuration may be based on an ID associated with each configured control resource 205. For example, the network (e.g., a functional unit of the core network, a base station associated with the transceiver node 105, etc.) may control the numbering (e.g., IDs) of the control resources 205-a in the first plurality for the transceiver node 105-a and the control resources 205-b in the second plurality for the transceiver node 105-b such that the UE 115-a utilizes aspects of conventional oversubscription processing techniques (e.g., based on the lowest ID of each control resource 205). For example, the network (e.g., via any of the transceiver nodes 105) may use consecutive numbers for the plurality of control resources 205 corresponding to each transceiver node 105. The consecutive numbers may include control resources 205-a corresponding to transceiver node 105-a having IDs of 0, 2, 4, 6, etc., and control resources 205-b corresponding to transceiver node 105-b having IDs of 1, 3, 5, 7, etc. (e.g., alternating IDs). Accordingly, the decoding configuration selected by UE 115-a may use conventional techniques (e.g., starting with the lowest ID) to determine that UE 115-a selects to decode control signals received on control resource 205(ID 0) corresponding to transceiver node 105-a, then to determine that UE 115-a selects to decode control signals received on control resource 205(ID 1) corresponding to transceiver node 105-b, then to determine that UE 115-a selects to decode control signals received on control resource 205(ID 2) corresponding to transceiver node 105-a, and so on. The UE 115-a may continue with this control resource 205 selection in a sequential order with respect to the control resources 205, e.g., first decode the control signal received on the control resource 205 with ID 0, then ID 1, then ID 2, then ID 3, and so on. Accordingly, the decoding configuration ensures that the UE 115-a is able to decode control signals received on the control resources 205 for each associated transceiver node 105 within its decoding limits.

Other aspects of this example may include other numbering configurations for control resources 205, e.g., the numbering may include control resources 205-a corresponding to transceiver node 105-a having an ID of 0, 3, 8, 11, etc., and control resources 205-b corresponding to transceiver node 105-b having an ID of 1, 5, 9, 13, etc. In this example, the network may configure the transceiver node 105 with IDs 0, 1, 3, 5, 8, 9, 11, 13 for the transceiver node 105 with which the UE 115-a communicates. When the UE 115-a selects the control signal received on the control resource 205 for decoding using conventional techniques (e.g., selecting consecutive IDs based on the lowest ID from all control resources 205 configured for the UE 115-a), this ensures that the control resources 205 are selected alternately for each associated transceiver node 105.

Additionally or alternatively, the decoding configuration may be based on the control resource 205ID and the ID associated with each respective transceiver node 105. The network may use any ID for the control resource 205 corresponding to each respective transceiver node 105. For example, the number may include control resources 205-a corresponding to transceiver node 105-a having an ID of 0, 1, 2, 3, etc., and control resources 205-b corresponding to transceiver node 105-b having an ID of 4, 5, 6, 7, etc. The decoding configuration selected by the UE 115-a may include (e.g., starting with the lowest ID and for the first transceiver node): UE 115-a selects to decode control signals received on the lowest ID control resource 205(ID 0) corresponding to transceiver node 105-a, then UE 115-a selects to decode control signals received on the lowest ID control resource 205(ID 4) corresponding to transceiver node 105-b, and then UE 115-a selects to decode control signals received on the next lowest ID control resource 205(ID 1) corresponding to transceiver node 105-a. The UE 115-a may continue the selection in ascending order for the control resources 205 corresponding to each transceiver node 105 to decode the control signals received on the control resources 205. Accordingly, the decoding configuration ensures that the UE 115-a is able to decode control signals received on the control resources 205 for each associated transceiver node 105 within its decoding limits. Other aspects of this example may include other numbering configurations for control resources 205, e.g., the numbering may include control resources 205-a corresponding to transceiver node 105-a having an ID of 0, 1, 4, 7, etc., and control resources 205-b corresponding to transceiver node 105-b having an ID of 2, 3, 5, 6, etc.

Additionally or alternatively, the decoding configuration may be based on a decoding limit associated with the UE 115-a and the number of transceiver nodes 105. For example, the UE 115-a may allocate its decoding restrictions among the associated transceiver nodes 105 without regard to the ID used to control the resources 205. The network may use any ID for the control resource 205 corresponding to each respective transceiver node 105. As an example, the number may include control resources 205-a corresponding to transceiver node 105-a having an ID of 0, 3, 5, 6, etc., and control resources 205-b corresponding to transceiver node 105-b having an ID of 1, 2, 4, 7, etc. The decoding configuration selected by the UE 115-a may include: the UE 115-a selects to decode a control signal received on the lowest control resource 205ID (e.g., ID 0) for transceiver node 105-a, selects to decode a control signal received on the lowest control resource 205ID (e.g., ID 1) for transceiver node 105-b, selects to decode a control signal received on the next lowest control resource 205ID (e.g., ID 3) for transceiver node 105-a, and so on. In other examples, the UE 115-a may select to decode control signals received on the control resources 205 corresponding to the first transceiver node 105-a up to the portion of the decoding constraints assigned to the first transceiver node 105-a, and then turn to other transceiver nodes, select to decode control signals received on the control resources 205 corresponding to each transceiver node 105 up to the respective assignment to that transceiver node 105 in the decoding constraints. Accordingly, the decoding configuration ensures that the UE 115-a is able to decode the control resources 205 corresponding to each associated transceiver node 105 within its decoding limits.

It is to be understood that the control resource 205ID configured by the network for each associated transceiver node 105 may use any numbering scheme. For example, the network may number a set of search spaces (e.g., control resources 205) configured for UE 115-a with IDs that are not consecutive, e.g., IDs 0, 2, 5, 7, 9, 12, 13, 15 may be used for eight sets of control resources. Any other numbering scheme for controlling the resource 205ID may be used by the network without departing from the scope of this description.

In some aspects, the UE 115-a may receive a signal identifying the control resource 205ID from a respective transceiver node 105, from a single transceiver node 105, and/or from a different entity (e.g., such as a core network and/or from a base station coordinating with the transceiver node 105). Further, the UE 115-a may receive a signal identifying the transceiver node 105 from the respective transceiver node 105, from a single transceiver node 105, and/or from a different entity (e.g., such as a core network and/or from a base station coordinating with the transceiver node 105).

In some aspects, any of the decoding configurations may include: the UE 115-a decodes a number of control signals received on the control resource 205 up to its decoding limit. In some aspects, any of the decoding configurations may include: the UE 115-a decodes a number of control signals received on the control resource 205 that satisfy a threshold (e.g., until channel estimation is complete, based on a successful number of BDs, etc.).

In some aspects, any of the decoding configurations may include: UE 115-a decodes the two (or more) control signals received on control resource 205 corresponding to transceiver node 105-a, and then decodes the two (or more) control signals received on control resource 205 corresponding to transceiver node 105-b, and so on. Accordingly, the described decoding configuration is not limited at all to: the UE 115-a decodes one control signal received on the control resource 205 corresponding to the transceiver node 105-a and then decodes one control signal received on the control resource 205 corresponding to the transceiver node 105-b. In general, the number of control signals received on a control resource 205 corresponding to one transceiver node 105 that the UE 115-a decodes before turning to decoding control signals received on a control resource 205 corresponding to another transceiver node 105 may be based on a decoding limit of the UE 115-a, a number of control resources 205 included in the plurality of control resources, and/or the like.

In some aspects, the decoding configuration may include: one or more of the transceiver nodes 105 configure and/or actually transmit only a portion (or subset) of the configured plurality of control resources 205. For example, based on the decoding restrictions of the UE 115-a, the network (e.g., base station, core network, TRP, etc.) may send only a first portion or subset of the control signals (e.g., the control resource 205 with the lowest ID) on the control resources 205 configured for the UE 115-a.

Fig. 3 illustrates an example of a decoding configuration 300 that supports oversubscription processing for multiple transceiver nodes, in accordance with aspects of the present disclosure. In some examples, the decoding arrangement 300 may implement aspects of a wireless communication system 100/200. Aspects of the decoding configuration 300 may be implemented by a transceiver node, UE, base station, and/or network (which may be examples of corresponding devices described herein).

In general, decoding configuration 300 illustrates an example of a decoding configuration followed by a UE to perform decoding operations on control information received on various control resources. For example, the UE may be configured to have or otherwise identify a first plurality of control resources 305 and a second plurality of control resources 310, the first plurality of control resources 305 being associated with or otherwise configured by a first transceiver node (TRP 1), the second plurality of control resources 310 being associated with or otherwise configured by a second transceiver node (TRP 2). In some aspects, each of the plurality of control resources 305 and 310 may include a plurality of control resources 315 (e.g., a set of search spaces) configured for a respective transceiver node for use by the UE in receiving control information, performing channel estimation, and so on. For ease of reference, only one control resource 315 is labeled in FIG. 3. Further, it is to be understood that each of the plurality of control resources 305 and/or the plurality of control resources 310 can include more or fewer control resources 315.

In some aspects, the decoding configuration 300 may comprise: the UE selects a first control signal received on a first control resource 315 from the first plurality of control resources 305 to be decoded in a sequential order based at least in part on an ID associated with each control resource 315 prior to selecting a second control signal received on a second control resource 315 from the second plurality of control resources 310 to be decoded. For example, the decoding configuration 300 includes using alternate IDs for each control resource 315 corresponding to different transceiver nodes. For example, an ID for a control resource 315 corresponding to a first transceiver node may be selected to have alternating IDs with respect to IDs of control resources 315 corresponding to a second transceiver node.

In the example of fig. 3, the IDs for the control resources 315 corresponding to the first transceiver node may be configured as 0, 2, 4, and 6, and the IDs for the control resources 315 corresponding to the second transceiver node may be configured as 1, 3, 5, and 7. Accordingly, decoding configuration 300 illustrates an example decoding configuration in which a UE may begin with a selection to decode control signals received on control resource 315(ID 0) corresponding to a first transceiver node, then a selection by the UE to decode control signals received on control resource 315(ID 1) corresponding to a second transceiver node, then a selection by the UE to decode control signals received on control resource 315(ID 2) corresponding to the first transceiver node, and continue with a selection by the UE to decode control signals received on control resource 315(ID 3) corresponding to the second transceiver node, and so on. Thus, from the UE perspective, the UE continuously selects to decode consecutive control resources 315 (e.g., from the ID (0, 1, 2, 3, etc.) where the actual control resources 315 corresponding to the perspective of the respective transceiver node use alternate IDs. In this manner, the network working with the respective transceiver node configures the ID for the control resources 315 so that the UE can follow conventional techniques while ensuring that the UE implements an efficient and effective decoding configuration, e.g., ensuring that the UE decodes the control resources 315 corresponding to each associated transceiver node. It is to be understood that other numbering techniques may be used for the control resources 315 corresponding to each transceiver node, e.g., TRP 1 may be configured with control resource IDs 0, 3, 8, 11 and TRP 2 may be configured with control resource IDs 1, 5, 9, 13.

The example decoding configuration 300 shows the UE alternating between: the control signals received on the control resources 315 corresponding to the first transceiver node are selected to be decoded, then the control signals received on the control resources 315 corresponding to the second transceiver node are selected to be decoded, and then a switch back to the first transceiver node is made to select the control signals received on the control resources 315 to be decoded. However, it is to be understood that other iterations may also be supported in accordance with aspects of the described techniques. For example, the UE may select to decode two or all control signals received on control resources 315 corresponding to a first transceiver node, select to decode two or all control signals received on control resources 315 corresponding to a second transceiver node, and then switch back to the first transceiver node to select to decode additional control signals received on control resources 315. Other configurations are also contemplated.

In some aspects, the UE may implement a decoding configuration 300 for decoding control signals received on control resources 315 as much as allowed according to its decoding restrictions. In other aspects, the UE may implement a decoding configuration 300 for decoding only a required number of control signals received on the control resources 315 until a condition or threshold is met. Example conditions or thresholds may include: the UE decodes enough control signals received on the control resources 315 corresponding to each transceiver node in order to complete channel estimation, upon successful BD attempts, and so on.

In some aspects, the decoding configuration 300 follows some aspects of oversubscription processing based on the current SS set index (or ID). In some aspects, this may include: instead of assigning a subset of consecutive IDs from all IDs to the set of SSs for a TRP, the network assigns IDs alternately to sets of SSs associated with different TRPs. Thus, in the example decoding configuration 300, eight USS sets of IDs 0-7 are configured in a slot with the lowest to highest IDs assigned to the USS. For example, the network configures the USS set corresponding to TRP 1 and TRP 2 with alternating IDs. Five BDs may be required for each USS set, and the BD budget remaining after processing the CSS set may be 20. According to the oversubscription process based on the BD restrictions, the UE can process USS sets 0 and 2 for TRP 1 and USS sets 1 and 3 for TRP 2.

Fig. 4 illustrates an example of a decoding configuration 400 that supports oversubscription processing for multiple transceiver nodes, in accordance with aspects of the present disclosure. In some examples, the decoding configuration 400 may implement aspects of the wireless communication system 100/200 and/or the decoding configuration 300. Aspects of the decoding configuration 400 may be implemented by a transceiver node, UE, base station, and/or network (which may be examples of corresponding devices described herein).

In general, decoding configuration 400 illustrates an example of one decoding configuration for a UE to perform decoding operations on control information received on various control resources. For example, the UE may be configured to have or otherwise identify a first plurality of control resources 405 and a second plurality of control resources 410, the first plurality of control resources 405 being associated with or otherwise configured by a first transceiver node (TRP 1), and the second plurality of control resources 410 being associated with or otherwise configured by a second transceiver node (TRP 2). In some aspects, each of the plurality of control resources 405 and 410 may include a plurality of control resources 415 (e.g., a set of search spaces) corresponding to a respective transceiver node for use by the UE in receiving control information, performing channel estimation, and so on. For ease of reference, only one control resource 415 is labeled in FIG. 4. Further, it is to be understood that each of the plurality of control resources 405 and/or the plurality of control resources 410 may include more or fewer control resources 415.

In some aspects, the decoding configuration 400 may include: the UE selects to decode the control signal received on control resource 415 based at least in part on both the control resource 415ID and the ID for each associated transceiver node. That is, the UE may select a decoding configuration that takes into account both the control resource 415ID and the transceiver node ID to ensure that the control signals received on the control resource 415 corresponding to each transceiver node are decoded. This may include: the UE selects to decode a first control signal received on a first control resource 415 from the first plurality of control resources 405, selects to decode a second control signal received on a second control resource 415 from the second plurality of control resources 410, selects to decode a third control signal received on a third control resource 415 from the first plurality of control resources 405, and so on. The UE may repeat this operation in an iterative manner in accordance with the decoding configuration 400 to ensure that control signals received on the control resources 415 corresponding to each associated transceiver node are selected for decoding.

With respect to control resource 415ID, the UE may select, in a first iteration, to decode control signals received on control resource 415 having the lowest ID (e.g., ID 0) corresponding to a first transceiver node, and select, in a second iteration, to decode control signals received on control resource 415 having the lowest ID (e.g., ID 4) corresponding to a second transceiver node, and so on. Accordingly, and as shown in decoding configuration 400, the UE may choose to decode a control signal received on control resource 415(ID 0) corresponding to a first transceiver node, then choose to decode a control signal received on control resource 415(ID 4) corresponding to a second transceiver node, then choose to decode a control signal received on control resource 415(ID 1) corresponding to the first transceiver node, and so on. In this manner, the network working with the respective transceiver node configures the ID for the control resource 415 so that the UE can follow aspects of conventional techniques while ensuring that the UE implements an efficient and effective decoding configuration, e.g., ensuring that the UE decodes the control resource 415 corresponding to each associated transceiver node. It is to be understood that other numbering techniques may be used for the control resources 415 corresponding to each transceiver node, e.g., TRP 1 may be configured with control resource IDs 0, 1, 4, 7 and TRP 2 may be configured with control resource IDs 2, 3, 5, 6.

Aspects of the decoding configuration 400 may include: the UE determines or otherwise identifies IDs associated with the first transceiver node and the second transceiver node. In some examples, the UE may determine the ID of the transceiver node based on explicit signaling (e.g., from the respective transceiver node, from a single transceiver node, from a base station, etc.). In some examples, the UE may determine the ID of the transceiver node based on a one-to-one mapping between the transceiver node and another entity, such as a control resource set (coreset), a cell ID, and so on. For example, a particular coreset/cell ID or a group of coreset/cell IDs may be associated with a single transceiver node.

The example decoding configuration 400 shows the UE alternating between: control signals received on control resources 415 corresponding to a first transceiver node are decoded, then control signals received on control resources 415 corresponding to a second transceiver node are decoded, and then a switch back to the first transceiver node to decode control signals received on control resources 415. However, it is to be understood that other iterations may also be supported in accordance with aspects of the described techniques. For example, the UE may choose to decode two control signals received on control resources 415 (IDs 0 and 1) corresponding to a first transceiver node, decode two more control signals received on control resources 415 (IDs 4 and 5) corresponding to a second transceiver node, and then switch back to the first transceiver node to decode additional control signals received on control resources 415. Other configurations are also contemplated.

In some aspects, the UE may implement a decoding configuration 400 for decoding control signals received on control resources 415 as much as allowed according to its decoding restrictions. In other aspects, the UE may implement a decoding configuration 400 for decoding only a required number of control signals received on the control resources 415 until a condition or threshold is met. Example conditions or thresholds may include: the UE decodes enough control signals received on the control resources 415 corresponding to each transceiver node in order to complete channel estimation, upon successful BD attempts, and so on.

In some aspects, decoding configuration 400 illustrates an example in which oversubscription processing is based on both a TRP ID (e.g., a transceiver node ID) and an SS set ID (e.g., a control resource 415 ID). For example, when the UE counts the number of BDs or CCEs used for the USS set (starting with the TRP with the lowest TRP ID), the UE counts the lowest ID USS set associated with the TRP that has not yet been counted. The UE then switches to the next higher ID TRP to check the USS set. As one non-limiting example, eight USS sets are configured, with four lowest USS set IDs for TRP 1 and four other USS set IDs for TRP 2. Five BDs can be used per USS set, and the BD budget remaining after processing the CSS set is 20. USS sets 0 and 1 are processed for TRP 1 and USS sets 4 and 5 are processed for TRP 2 according to the BD restriction based oversubscription process.

Fig. 5 illustrates an example of a decoding configuration 500 that supports oversubscription processing for multiple transceiver nodes, in accordance with aspects of the present disclosure. In some examples, the decoding configuration 500 may implement aspects of the wireless communication system 100/200 and/or the decoding configuration 300/400. Aspects of the decoding configuration 500 may be implemented by a transceiver node, UE, base station, and/or network (which may be examples of corresponding devices described herein).

In general, decoding configuration 500 illustrates an example of one decoding configuration that may be selected by a UE for performing decoding operations on control information received on various control resources. For example, the UE may be configured to have or otherwise identify a first plurality of control resources 505 associated with or otherwise configured by a first transceiver node (TRP 1) and a second plurality of control resources 510 associated with or otherwise configured by a second transceiver node (TRP 2). In some aspects, each of the plurality of control resources 505 and 510 may include a plurality of control resources 515 (e.g., a set of search spaces) corresponding to a respective transceiver node for use by the UE in receiving control information, performing channel estimation, and so on. For ease of reference, only one control resource 515 is labeled in FIG. 5. Further, it is to be understood that each of the plurality of control resources 505 and/or the plurality of control resources 510 can include more or fewer control resources 515.

In some aspects, the decoding configuration 500 may include: the UE selects a control signal to decode received on control resource 515 based at least in part on the ID for each associated transceiver node and the decoding restrictions of the UE. That is, the UE may select a decoding configuration that takes into account the transceiver node IDs to ensure that control signals received on the control resources 515 corresponding to each transceiver node are decoded up to the decoding limit of the UE. The UE may divide its decoding restrictions among the associated transceiver nodes (e.g., assign a first transceiver node a portion of the decoding restrictions and assign a second transceiver node another portion of the decoding restrictions). The UE may then select to decode control signals received on control resources 505 corresponding to the first transceiver node up to its assigned decoding limit (of the first transceiver node), and then select to decode control signals received on control resources 515 corresponding to the second transceiver node up to its assigned decoding limit (of the second transceiver node). That is, the UE may select the portions of the decoding constraints allocated for each transceiver node to be decoded in any order on the control signals received on the control resources 515 corresponding to each transceiver node.

With respect to control resource 515ID, the UE may optionally select to decode a control signal received on the control resource 515 with the lowest ID (e.g., ID 0) corresponding to the first transceiver node, select to decode a control signal received on the control resource 515 with the lowest ID (e.g., ID 1) corresponding to the second transceiver node, and so on. In another example, the UE may select to decode control signals received on control resources 515(ID 0 and ID 3) corresponding to a first transceiver node (e.g., up to the portion of the decoding constraints assigned to the first transceiver node) and then select to decode control signals received on control resources 515(ID 1 and ID 2) corresponding to a second transceiver node (e.g., up to the portion of the decoding constraints assigned to the second transceiver node). In this manner, the network working with the respective transceiver node configures the control resources 515 with IDs so that the UE can follow aspects of conventional techniques while ensuring that the UE implements an efficient and effective decoding configuration, e.g., that the UE decodes control signals received on the control resources 515 corresponding to each associated transceiver node.

Aspects of the decoding configuration 500 may include: the UE determines or otherwise identifies IDs associated with the first transceiver node and the second transceiver node. In some examples, the UE may determine the ID of the transceiver node based on explicit signaling (e.g., from the respective transceiver node, from a single transceiver node, from a base station, etc.). In some examples, the UE may determine the ID of the transceiver node based on a one-to-one mapping between the transceiver node and another entity (such as a coreset, cell ID, etc.). For example, a particular coreset/cell ID or a group of coreset/cell IDs may be associated with a single transceiver node.

Example decoding configuration 500 may include: the UE selects to decode control signals received on the control resource 515 corresponding to the first transceiver node up to its assigned decoding limit, and then selects to decode control signals received on the control resource 515 corresponding to the second transceiver node up to its assigned decoding limit. However, it is to be understood that other iterations may also be supported in accordance with aspects of the described techniques.

In some aspects, the UE may implement a decoding configuration 500 for decoding control signals received on control resource 515 as much as allowed according to its decoding limitations. In other aspects, the UE may implement a decoding configuration 500 for decoding only a required number of control signals received on the control resource 515 until a condition or threshold is met. Example conditions or thresholds may include: the UE decodes enough control signals received on the control resources 515 corresponding to each transceiver node in order to complete channel estimation, upon successful BD attempts, and so on.

In some aspects, the decoding configuration 500 shows an example as follows: wherein the UE splits CCE/BD restrictions (e.g., decoding restrictions) among the TRPs and counts BD and number of CCEs for the USS set (e.g., control resource 515) associated with each TRP based on the USS set ID. BD and CCE budgets of the USS set associated with a TRP may be consumed until a limit for each TRP is reached. For each TRP, the set of SSs with lower ID may optionally be counted before the set of SSs with higher ID. As one non-limiting example, the UE may be configured with eight USS sets, with four USS sets configured for each TRP. Five BDs may be required for each USS set, and the BD budget remaining after counting CSS sets is 20. According to the oversubscription process based on BD restriction splitting between TRPs, the UE can process USS sets 0 and 3 for TRP 1 and USS sets 1 and 2 for TRP 2.

Fig. 6 shows an example of a process 600 to support oversubscription processing for multiple transceiver nodes, in accordance with aspects of the present disclosure. In some examples, the process 600 may implement aspects of the wireless communication system 100/200 and/or the decoding configuration 300/400/500. Aspects of the process 600 may be implemented by the first transceiver node 605, the UE 610, and/or the second transceiver node 615 (which may be examples of corresponding devices described herein). In some aspects, the first transceiver node 605 and the second transceiver node 615 may be examples of TRPs.

At 620, the first transceiver node 605 may identify a plurality of control resources for the UE 610. For example, the first transceiver node 605 may configure the plurality of control resources individually, may coordinate with the second transceiver node 615 to configure the plurality of control resources, and may be configured by a control entity (e.g., a base station, a core network, etc.).

At 625, the second transceiver node 615 may identify a plurality of control resources for the UE 610. For example, the second transceiver node 615 may configure the plurality of control resources individually, may coordinate with the first transceiver node 605 to configure the plurality of control resources, may be configured with the plurality of control resources by a control entity (e.g., a base station, a core network, etc.).

At 630, the first transceiver node 605 may configure an ID for each of the plurality of control resources. In some aspects, this may include: the ID for each control resource is configured using a consecutive number or using a non-consecutive number. In some aspects, this may include: the ID for each control resource is configured based on the ID associated with the first transceiver node 605. In some aspects, this may include: the ID for each control resource is configured based on the number of transceiver nodes associated with the UE 610. For example, the first transceiver node 605 may use alternate IDs such that when combined with control resource IDs from other transceiver nodes, the control resource IDs are consecutive.

At 635, the second transceiver node 615 may configure an ID for each of the plurality of control resources. In some aspects, this may include: the ID for each control resource is configured using a consecutive number or using a non-consecutive number. In some aspects, this may include: the ID for each control resource is configured based on the ID associated with the second transceiver node 615. In some aspects, this may include: the ID for each control resource is configured based on the number of transceiver nodes associated with the UE 610. For example, the second transceiver node 615 may use alternate IDs such that when combined with control resource IDs from other transceiver nodes, the control resource IDs are consecutive.

The techniques described herein may be used for various wireless communication systems such as code division multiple access (CMDA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and others. A CDMA system may implement a radio technology such as CDMA2000, Universal Terrestrial Radio Access (UTRA), and the like. CDMA2000 covers IS-2000, IS-95 and IS-856 standards. The IS-2000 release may be commonly referred to as CDMA 20001X, 1X, etc. IS-856(TIA-856) IS commonly referred to as CDMA 20001 xEV-DO, High Rate Packet Data (HRPD), etc. UTRA includes wideband CDMA (W-CDMA) and other variants of CDMA. TDMA systems may implement wireless technologies such as global system for mobile communications (GSM).

The OFDMA system may implement wireless technologies such as Ultra Mobile Broadband (UMB), evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE)802.11(Wi-Fi), IEEE 802.16(WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). LTE, LTE-A and LTE-A Pro are releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE-A, LTE-A Pro, NR, and GSM are described in documents from an organization named "3 rd Generation partnership project" (3 GPP). CDMA2000 and UMB are described in documents from an organization named "3 rd generation partnership project 2" (3GPP 2). The techniques described herein may be used for the systems and wireless techniques mentioned above as well as other systems and wireless techniques. Although aspects of the LTE, LTE-A, LTE-A Pro or NR system may be described for purposes of illustration, and LTE, LTE-A, LTE-A Pro or NR terminology may be used in much of the description, the techniques described herein may be applied beyond LTE, LTE-A, LTE-A Pro or NR applications.

A macro cell typically covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 115 with service subscriptions with the network provider. The small cell may be associated with a lower power base station 105 than the macro cell, and the small cell may operate in the same or different (e.g., licensed, unlicensed, etc.) frequency band as the macro cell. Small cells may include pico cells, femto cells, and micro cells according to various examples. For example, a pico cell may cover a smaller geographic area and may allow unrestricted access by UEs 115 with service subscriptions with the network provider. A femto cell may also cover a smaller geographic area (e.g., a home) and may provide restricted access by UEs 115 with association with the femto cell (e.g., UEs 115 in a Closed Subscriber Group (CSG), UEs 115 for in-home users, etc.). An eNB for a macro cell may be referred to as a macro eNB. An eNB for a small cell may be referred to as a small cell eNB, pico eNB, femto eNB, or home eNB. An eNB may support one or more (e.g., two, three, four, etc.) cells and may also use one or more component carriers to support communication.

One or more of the wireless communication systems 100 described herein may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and transmissions from different base stations 105 may not be aligned in time. The techniques described herein may be used for synchronous or asynchronous operations.

Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

The various illustrative blocks and modules described in connection with the present disclosure may be implemented or performed with a general purpose processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable Logic Device (PLD), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration).

The functions described herein may be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If embodied in software executed by a processor, the functions may be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Other examples and implementations are within the scope of the disclosure and the appended claims. For example, due to the nature of software, the functions described above can be implemented using software executed by a processor, hardware, firmware, hard wiring, or any combination of these. Features implementing functions may also be physically located at various locations, including in a distributed fashion where portions of the functions are implemented at different physical locations.

Computer-readable media includes both non-transitory computer storage media and communication media including any medium that facilitates transfer of a computer program from one location to another. Non-transitory storage media may be any available media that can be accessed by a general purpose or special purpose computer. By way of example, and not limitation, non-transitory computer-readable media can comprise Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory, Compact Disc (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code means in the form of instructions or data structures and that can be accessed by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. Further, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of medium. Disk and disc, as used herein, includes CD, laser disc, optical disc, Digital Versatile Disc (DVD), floppy disk and blu-ray disc where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above are also included within the scope of computer-readable media.

As used herein (including in the claims), an "or" as used in a list of items (e.g., a list of items ending with a phrase such as "at least one of" or "one or more of") indicates an inclusive list such that, for example, a list of at least one of A, B or C means a, or B, or C, or AB, or AC, or BC, or ABC (i.e., a and B and C). Further, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an exemplary step described as "based on condition a" may be based on both condition a and condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "based at least in part on" is interpreted.

In the drawings, similar components or features may have the same reference numerals. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If only the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label or other subsequent reference labels.

The description set forth herein in connection with the appended drawings describes example configurations and is not intended to represent all examples that may be implemented or within the scope of the claims. The term "exemplary" as used herein means "serving as an example, instance, or illustration," and is not "preferred" or "advantageous over other examples. The detailed description includes specific details for the purpose of providing an understanding of the described technology. However, the techniques may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.

The description herein is provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to the disclosure will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the present disclosure is not intended to be limited to the examples and designs described herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
