Detailed Description

The disclosed technology provides implementation paradigms and examples of downlink control signaling in wireless communications. Some embodiments of the disclosed technology propose an efficient power saving technique to instruct a user equipment to perform its operation based on Information included in DCI (Downlink Control Information). In some embodiments, the DCI includes information to control one or more user devices to help the user devices save power consumption and improve performance.

Fig. 1 shows an example of a wireless communication system (e.g., a 5G or NR cellular network) including a BS 120 and one or more User Equipments (UEs) 111, 112, and 113. In some embodiments, the UE accesses the BS (e.g., network) using an implementation of the disclosed techniques (131, 132, 133), which then enables subsequent communication (141, 142, 143) from the BS to the UE. The UE may be, for example, a smartphone, a tablet, a mobile computer, a machine-to-machine (M2M) device, an Internet of Things (IoT) device, and so on.

Fig. 2 shows an example of a block diagram representation of a portion of an apparatus. An apparatus 210, such as a base station or wireless device (or UE), may include processor electronics 220, such as a microprocessor implementing one or more of the techniques presented in this document. Apparatus 210 may include transceiver electronics 230 to transmit and/or receive wireless signals over one or more communication interfaces, such as antenna 240. The apparatus 210 may include other communication interfaces for sending and receiving data. The apparatus 210 may include one or more memories (not explicitly shown) configured to store information, such as data and/or instructions. In some embodiments, processor electronics 220 may include at least a portion of transceiver electronics 230. In some embodiments, at least some of the disclosed techniques, modules, or functions are implemented using the apparatus 210.

Power consumption of the user equipment is an important factor affecting the user experience. Various embodiments of the disclosed technology provide power saving techniques for user equipment in a wireless communication system. In some embodiments of the disclosed technology, to improve network performance, power saving techniques propose to encode some information of one or more UEs (user equipments) together to reduce the size of the DCI payload.

When DRX (Discontinuous Reception) is configured, the UE does not have to continuously monitor a PDCCH (physical downlink control channel). Figure 3 shows an example of a DRX cycle with some parameters. DRX is characterized as follows:

-duration of opening: the UE waits for a duration to receive the PDCCH after waking up. If the UE successfully decodes the PDCCH, the UE keeps waking up and starts an inactive timer;

-inactivity timer: from the last time the PDCCH was successfully decoded, the UE waits for the duration of time to successfully decode the PDCCH, and if it fails, it may return to the sleep state. Only for the first transmission (i.e., not used for retransmission), after a single successful decoding of the PDCCH, the UE should restart the inactivity timer;

-a retransmission timer: a duration until retransmission can be expected;

-a period: specifying a periodic repetition of an on-duration followed by a possible inactive period;

-activation time: the UE monitors the total duration of the PDCCH. This includes the "on duration" of the DRX cycle, the time the UE performs continuous reception when the inactivity timer has not expired, and the time the UE performs continuous reception while waiting for a retransmission opportunity.

Even with the DRX configuration, the UE needs to wake up periodically to monitor the PDCCH, which may cause unnecessary power consumption when there is no data transmission or reception during the on duration.

For PDCCH monitoring, the period of its search space may be configured through RRC (Radio Resource Control) signaling. Multiple (e.g., up to 10) search spaces may be configured per downlink BWP (bandwidth portion). PDDCH monitoring occasions within the search space are related to period, offset and duration, PDCCH monitoring pattern within the time slot, etc. Fig. 4 shows an example of a diagram illustrating PDCCH monitoring. In fig. 4, the period is 4 slots, the offset is 1 slot, and the duration is 2 slots. The PDCCH monitoring pattern within a slot is a 14-bit bitmap. In an example, the PDCCH monitoring occasion is configured by higher layer signaling.

For BWP adaptation, the UE may be configured with multiple BWPs. Dynamic BWP handover may be implemented through DCI indication and/or a timer.

For CA-DC (Carrier Aggregation-dual Connection) operation, Scell (Secondary Cell) may be deactivated by a timer or a MAC CE (Control Element).

For current schemes in the spatial domain, the MIMO configuration (e.g., configuring the number of antenna ports) depends on UE capabilities, channel conditions, higher layer parameters, etc. The spatial configuration cannot dynamically adapt to the arriving traffic.

In the time domain, the time domain resource allocation parameters include K0, K1, K2, and a-CSI (Aperiodic CSI) offsets. A list of some examples of time domain resource allocation parameters, such as K0, K1, and K2, is configured by RRC signaling, and the actual parameters used in scheduling are indicated by DCI (downlink control information). The a-CSI (aperiodic CSI) offset is related to the QCL (quasi co-located) type. In the current scheme, the UE is not aware of the time domain resource allocation before the PDCCH is decoded, or the time domain resource allocation is related to the QCL type, which potentially increases the power consumption of the UE.

K0: time slot offset between DCI and its scheduled PDSCH (Physical Downlink Shared Channel)

K1: giving a PDSCH to DL (downlink) ACK (acknowledgement) timing;

k2: time slot offset between DCI and its scheduled PUSCH (Physical Uplink Shared Channel)

The a-CSI offset aperiodicTriggeringOffset is an offset between a slot containing DCI triggering a set of aperiodic NZP (Non-Zero Power) CSI-RS resources and a slot in which a set of CSI-RS resources is sent.

To further reduce UE power consumption, some embodiments of the disclosed technology provide a more energy efficient method of introducing a power save signal to instruct the UE to wake up when necessary. In some embodiments, the power save signal may be configured with other functions, such as PDCCH monitoring information, BWP handover, Scell operation, spatial domain information, time domain information, SRS request, CSI request, QCL information, etc., to further reduce power consumption or improve network performance.

Some embodiments of the disclosed technology provide a wireless communication method as shown in fig. 5 and 6. In fig. 5, the method includes transmitting, by the network device, control signaling to the user equipment, the control signaling including N data blocks indicating T trigger states of the M user equipment, and wherein N, T and M are natural numbers, and the trigger states indicate configuration information of the M user equipment. In some embodiments, the control signaling includes a control information format indicator. In some embodiments, the control signaling includes a functionality indicator. In some embodiments, N is equal to 1.

In fig. 6, the method includes: receiving, by a user equipment, control signaling from a network device, the control signaling comprising N data blocks indicating T trigger states of M user equipments, and wherein N, T and M are natural numbers, and the trigger states indicate configuration information of the M user equipments. In some embodiments, the control signaling includes a control information format indicator. In some embodiments, the control signaling includes a functionality indicator. In some embodiments, N is equal to 1.

Example 1

In some embodiments, each of the M user devices is configured with one data block.

In some examples, the fields of the data block are defined in table 1. For a UE configured with a data block, trigger state-0 is indicated by the value of the data block or code point "00", trigger state-1 is indicated by the value of the data block or code point "01", trigger state-2 is indicated by the value of the data block or code point "10", and trigger state-3 is indicated by the value of the data block or code point "11".

[ Table 1]

In some examples, multiple user devices configured with the same set of parameters may be indicated by the same data block. In this embodiment, the trigger states of multiple user equipments are encoded in one DCI payload. Thus, the resource overhead can be greatly reduced compared to a scheme in which the trigger states of a plurality of user equipments are encoded separately.

In some implementations, the user equipment is configured with location information. In some embodiments, the location information is used to configure the UE for extracting the trigger state from the DCI payload. In some embodiments, the interpretation of the trigger state of the user equipment is associated with location information. In some embodiments, the location information includes a start location and/or an end location of the data chunk. In some embodiments, the location information includes an index of the block number. In some embodiments, the location information includes a bit width of the data block or a size of the data block field. In some embodiments, the location information is configured by higher layer signaling. In some embodiments, the higher layer signaling comprises RRC signaling or MAC CE.

Example 2

In some embodiments, when the control signaling includes N data blocks, N is equal to 1. In some embodiments, the trigger states of M user devices or multiple user devices are jointly encoded. The trigger states of the M user equipments or of the plurality of user equipments are jointly encoded and indicated by a single value of the data block.

Examples of data block values are defined in table 2. In this example, the trigger states or configurations of multiple (e.g., M) user devices are jointly encoded and indicated by a single value of the data block. In this example, there are 3 UEs (UE-0, UE-1, UE-2), and each of the UEs has 3 trigger states (with indices of 0, 1, 2). A value or code point "0" indicates a trigger state with index 0 for UE-0, a trigger state with index 0 for UE-1, and a trigger state with index 0 for UE-2. A value or code point "1" indicates a trigger state with an index of 1 for UE-0, a trigger state with an index of 0 for UE-1, and a trigger state with an index of 0 for UE-2, and so on.

[ Table 2]

In this embodiment, the trigger states of multiple user equipments are jointly encoded in one data block and indicated by a value of the data block. Therefore, the load size can be reduced and the performance can be improved as compared with embodiment 1. More specifically, in the case where there are 3 user equipments and each user equipment has 3 trigger states, 2 (three trigger states) × 3 (the number of user equipments) ═ 6 bits are required for embodiment 1. However, for example 2, 5 bits are sufficient to indicate 3 × 3 — 27 combinations. Thus, in this example, one bit may be reduced. In case of different number of user equipments and different number of trigger states for each user equipment, more examples of reduced number of payload bits compared to embodiment 1 are given in table 3.

[ Table 3]

In those embodiments, the trigger state or configuration information is encoded together to reduce resource overhead and improve the performance of the wireless communication system. An example of BLER (block error rate) performance is given in fig. 7. In fig. 7, the legend for "case-1" is the performance of the technique as discussed in example-2 when there are 8 user equipments and each user equipment has 17 trigger states, and the legend for "case-2" is the performance of the technique as discussed in example-1.

In some embodiments, the trigger state of the user equipment indicated by the network is determined by or associated with at least one of: a value of a data block, a number of trigger states per user equipment, a mapping order of M user equipments, a number of trigger states of previous user equipments, a number of trigger states of user equipments having a less significant position, a number of trigger states of user equipments having a higher mapping order, a mapping order of previous user equipments, an order of user equipments having a less significant position, an order of user equipments having a higher mapping order, a mapping position of a user equipment or a number of trigger states of a user equipment.

In some embodiments, the value of the data block is determined by or associated with at least one of: a trigger state of a user equipment indicated by the network, a number of trigger states per user equipment, a mapping order or index of M user equipments, a number of trigger states of previous user equipments, a number of trigger states of user equipments having a less significant position, a number of trigger states of user equipments having a higher mapping order, a mapping order or index of previous user equipments, an order of user equipments having a less significant position, an order of user equipments having a higher mapping order, a mapping order or index of user equipments, or a number of trigger states of user equipments.

In some embodiments, the mapping order of the M user devices comprises an order in which values of the data blocks are formulated. In some examples, the value of data block C is determined by the following equation:

C＝a(Inf-UE-0)+b(Inf-UE-1,Inf-UE-0)+c(Inf-UE-2,Inf-UE-1,Inf-UE-0)+...+d(Inf-UE-N-1,Inf-UE-N-2,...,Inf-UE-1,Inf-UE-0).

in some examples, t0 ═ e (C, Inf-UE-0), t1 ═ f (C, Inf-UE-0, Inf-UE-1), t2 ═ g (C, Inf-UE-0, Inf-UE-1, Inf-UE-2), …, tN-1 ═ h (C, Inf-UE-0, Inf-UE-1, Inf-UE-2., Inf-UE-N-1), where a (x), b (x), C (x), d (x), e (x), f (x), g (x), and h (x) represent a function of x, while ti represents an indicated trigger state of the user equipment, 0 ≦ i ≦ N-1, and Inf-UE-i represent information of UE-i, 0 ≦ i ≦ N-1.

In some embodiments, the codepoint (codepoint) or value of the data block and the trigger state of the user equipment are determined as follows:

[ Table 4]

In some embodiments, the code point or value of the data block and the trigger state of the user equipment are determined as follows:

[ Table 5]

In some embodiments, the code point or value of the data block and the trigger state of the user equipment are determined as follows: c ═ T0+ T1 × T0+ T2 × T0 × T1+. + T (N-1) × T0 × T1 × T2 × T (N-2), where Ti is the number of trigger states of the ith user equipment, i ≦ N-1 for 0, and Ti is a natural number; ti is an index of the trigger state of the ith user equipment, i is more than or equal to 0 and less than or equal to N-1, and ti is a natural number; c is the code point of the data block.

In the example, the mapping order of the user equipments is UE-0, UE-1, UE-2, … …, UE-N-1. In an example, a user device with a smaller index is in front of or before a user device with a larger index. In an example, a user device with a smaller index has a less significant position. In an example, user devices with smaller indices have higher mapping orders.

In some embodiments, the predefined condition comprises at least one of: i) the trigger state of UE-i indicated by the data block is derived or associated with information or parameters of UE-j, ii) the trigger state of UE-j indicated by the data block is derived without requiring or being associated with information or parameters of UE-i. Where i and j are different user equipment indices and i and j are natural numbers.

In an example, the user equipment UE-j is in front of or before the user equipment UE-i when the predefined condition is met. In an example, user equipment UE-j has a lower effective position than user equipment UE-i when a predefined condition is met. In the example, user equipment UE-j has a higher mapping order than user equipment UE-i.

In some embodiments, the mapping order is represented by an index of the user equipment. In some examples, user devices with smaller indices have lower mapping orders. In some examples, user devices with larger indices have lower mapping orders.

Take table 2 as an example. There are 3 UEs (UE-0, UE-1, UE-2) and each of the UEs has 3 trigger states (index 0, 1, 2). If the value of the data block is 3, the trigger index of the UE-0 is T0 ═ mod (C, T0) ═ mod (3,3) ═ 0, T1 ═ mod (C/T0, T1) ═ mod (floor (3/3),3 ═ 1, T2 ═ mod (C/T0/T1, T2) ═ mod (floor (3/3/3),3) ═ 1. Conversely, if the index of the indicated trigger state of UE-0, UE-1 and UE-2 is 2, 1, the value of the data block is C-T0 + T0-T1 + T0-T1-T2-2 +3 + 1+ 3-1-14.

In some embodiments, the user equipment is configured with at least one of: information of a number of trigger states per user equipment, information of a mapping order or index of M user equipments, information of a number of trigger states of previous user equipments, a number of trigger states of user equipments having less significant positions, a number of trigger states of user equipments having a higher mapping order, a mapping order or index of previous user equipments, an order of user equipments having less significant positions, an order of user equipments having a higher mapping order, a mapping order or index of user equipments, or a number of trigger states of user equipments.

In some embodiments, the information of the number of trigger states of each user equipment, or the information of the number of trigger states of previous user equipments, or the information of the number of trigger states of user equipments having a less significant position, or the information of the number of trigger states of user equipments having a higher mapping order is in the form of a list or a set format. In some embodiments, the indices in the list or set indicate the mapping order. For example, there are three user equipments and the user equipments are configured with a list of values [3,5,7] corresponding to the number of trigger states for UE-0, UE-1, UE-3, respectively. In the example, the mapping order is first UE-0, then UE-1, and finally UE-2.

In some embodiments, the trigger state indicated by the block is determined by or associated with information of a previous user equipment, or information of a user equipment with a less significant position, or information of a user equipment with a higher mapping order. For example, there are three previous user equipments and the user equipments are configured with a list of values [3,5,7] corresponding to the number of trigger states for UE-0, UE-1, UE-3, respectively.

For example, when there are three previous user equipments, the fourth user equipment may be configured with a list of values corresponding to the number of trigger states of the first three user equipments [3,5,7 ]. For example, when there are three user equipments with less significant positions or a higher mapping order, the fourth user equipment may be configured with a list of values corresponding to the number of trigger states of the first three user equipments [3,5,7 ].

In some embodiments, the information of the number of trigger states of each user equipment, or the information of the number of trigger states of the previous user equipment, or the information of the number of trigger states of the user equipment having a less significant position, or the information of the number of trigger states of the user equipment having a higher mapping order is in a format of a differential value. By means of a differential approach, the overhead of signaling can be reduced.

In some embodiments, the trigger state indicated by the data block is determined by or associated with a mapping order or index of the user equipment and a number of trigger states of the user equipment. In some embodiments, the number of trigger states of the user equipment is the same. The user equipment may interpret the trigger state indicated by the data block with its mapping order or index and the number of trigger states.

In some examples, the indicated trigger state is ti ═ mod (operation-i (C/T _ temp), T), where T is the number of trigger states per user equipment, T is a natural number, for 0 ≦ i ≦ N-1; ti is an index of the indicated trigger state of the ith user equipment, i is more than or equal to 0 and less than or equal to N-1, and ti is a natural number; c is the code point of the data block; for i is more than or equal to 0 and less than or equal to N-1, operation-i is rounding-up, rounding-down or rounding-off operation. In this example, "^" is used to indicate the power function, and thus T ^ (i) indicates Tⁱ。

In some examples, the indicated trigger state is C ═ T0+ T1 ^ T + T2 ^ T2 +.. + T (N-1) × T ^ (N-2), where T is the number of trigger states per user equipment, T is a natural number; ti is an index of the indicated trigger state of the ith user equipment, i is more than or equal to 0 and less than or equal to N-1, and ti is a natural number; c is the code point of the data block.

Both embodiment 1 and embodiment 2 can reduce resource overhead and blocking rate, while embodiment 2 can further reduce the size of the payload.

In some embodiments, the control signaling may be included in a first set of DCI formats or a first set of DCI candidates (candidates). The first set of DCI formats or the first set of DCI candidates have a higher mapping priority than the second set of DCI formats or the second set of DCI candidates. The first set of DCI formats or the first set of DCI candidates and the second set of DCI formats or the second set of DCI candidates are distinguished by at least one of: DCI format, RNTI (Radio network temporary identifier), search space configuration, CORESET (control resource set) configuration, time resource, or frequency resource. In some embodiments, the second set of DCI formats or the second set of DCI candidates comprises at least one of: DCI format 0-0, DCI format 0-1, DCI format 1-0, DCI format 1-1, DCI format 2-0, DCI format 2-1, DCI format 2-2, DCI format 2-3.

Configuration information 1

In some embodiments, the wake-up information indicates whether the UE needs to monitor the second set of PDCCH candidates for a predefined period. In some embodiments, the wake-up information indicates whether the UE needs to monitor the PDCCH for a predefined period. In some embodiments, the wake-up information indicates whether the UE needs to monitor the second set of PDCCH candidates. In some embodiments, the wake-up information indicates whether the UE needs to monitor the PDCCH. In some embodiments, the wake information indicates a transition to the DRX state.

In some embodiments, the PDCCH monitoring period is equal to the period of the search space of the corresponding PDCCH candidate. In this case, the PDCCH monitoring behavior is processed per search space. For example, when the UE is configured with two PDCCH search spaces, search space 1 with period 1 and search space 2 with period 2, it is assumed that the information transmitted in the DCI indicates that the UE does not need to monitor the PDCCH in the next 2 PDCCH monitoring periods.

In some embodiments, the PDCCH monitoring period is equal to the maximum or minimum period of all search spaces. In some embodiments, the PDCCH monitoring period is equal to the maximum or minimum period of the search space for the second set of PDCCH candidates. For example, when the UE is configured with two PDCCH search spaces, i.e., search space 1 having period 1 and search space 2 having period 2 (where period 1 is less than period 2), it is assumed that the information transmitted in the DCI indicates that the UE does not need to monitor the PDCCH in the next 2 PDCCH monitoring periods. In this case, for both search space 1 and search space 2, the UE does not need to monitor the PDCCH candidates in the next 2 periods whose duration is equal to 2 times period 1. The duration of the inactivity time of the UE is 2 times the maximum of the periods in period 1 and period 2.

In some embodiments, the bit width of the ith block may be 1, where 0 ≦ i ≦ N-1.

In some embodiments, when the value of the ith block is value _1, this means that the UE needs to monitor a second set of PDCCH candidates or PDCCH candidates for the next N DRX cycles; when the value of the ith block is value _2, this means that the UE does not need to monitor the second set of PDCCHs or PDCCH candidates for the next N DRX cycles. In some embodiments, when the values of the ith block are all 0, this means that the UE does not need to monitor the second set of PDCCH candidates or PDCCH candidates for the next N DRX cycles, which means "not to wake up" or "go to sleep"

In some embodiments, when the value of the ith block is value _1, this means that the UE needs to monitor a second set of PDCCH candidates or PDCCH candidates for the next N DRX cycles; when the value of the ith block is value _2, this means that the UE does not need to monitor the second set of PDCCHs or PDCCH candidates for the next N DRX cycles. In some embodiments, when the values of the ith block are all 0, this means that the UE does not need to monitor the second set of PDCCH candidates or PDCCH candidates for the next N DRX cycles, which means "not to wake up" or "go to sleep"

In some embodiments, when the value of the i-th block is value _1, this means a transition of DRX on or DRX active time to DRX off or DRX inactive time; when the value of the ith block is value _2, this means a transition from the DRX off or DRX inactive time to the DRX on or DRX active time. In some embodiments, when the values of the ith block are all 0, this means a transition of DRX on or DRX active time to DRX off or DRX inactive time.

With the indication of the wake-up information, the UE does not need to wake up or may skip monitoring the PDCCH, which is beneficial for reducing power consumption.

Configuration information 2

The configuration information 2 may include information on a BWP (bandwidth part) indicator. If the UE does not support BWP activation via DCI change, the UE will ignore this information. Examples 1 to 3 are discussed below.

Example 1: the bit width for this configuration information is determined asA bit wherein

If n is_BWP,RRCN is less than or equal to 3_BWP＝n_BWP,RRC+1, in this case the bandwidth part indicator corresponds to the ascending order of the higher layer parameter BWP-Id. Wherein n is_BWP,RRCIs the number of DL BWPs configured by the higher layer, excluding the initial DL bandwidth part.

Else n_BWP＝n_BWP,RRCIn this case, the bandwidth part indicator is defined in table 6.

The UE ignores this information if the UE does not support the change of active BWP via DCI.

[ Table 6: bandwidth portion indicator

Example 2: the bit width for this configuration information is determined asA bit wherein

If n is_BWP,RRCN is less than or equal to 3_BWP＝n_BWP,RRC+1, in which case the bandwidth part indicator corresponds to the ascending order of the higher layer parameter BWP-Id; wherein n is_BWP,RRCIs the amount of UL BWP configured by higher layers, excluding the initial UL bandwidth portion

Else n_BWP＝n_BWP,RRCIn this case, the bandwidth part indicator is defined in table 6.

Example 3: in some embodiments, the BWP handover indication may be associated with a reference signal. In this case, the trigger state in the data block indicates that BWP is switched from the small BWP to the large BWP. A set of reference signals (TRS in fig. 7, but it could also be other CSI-RS, or both, or other reference signals, such as PT-RS) at T_{BWPswitchDelay}And then transmitted. In this example, the UE may get the channel condition or beam information of the large BWP soon after the BWP handover, which is beneficial to improve network performance.

For DCI-based BWP handover, after the UE receives a BWP handover request in slot n of the serving cell, the UE may be able to receive PDSCH (for DL active BWP handover) or transmit PUSCH (for UL active BWP handover) on the new BWP on the serving cell no later than slot n + T_{BWPswitchDelay}This occurs.

[ Table 7: examples of BWP handoff delays

In some embodiments, the downlink control signaling includes an identifier for a DCI format. The identifier field for the DCI format is 1 bit, and the 1 bit indicates an uplink or downlink BWP (bandwidth part) indicator. The indication bit may be configured separately for each block or common for all blocks. In some embodiments, the value of all 0 data blocks indicates no BWP switching.

With appropriate indication of the BWP indicator in the first set of PDCCH candidates, it is more advantageous for the UE to switch to a larger BWP for larger packet reception or transmission and to monitor the PDCCH candidates using a smaller BWP. Furthermore, BWP handover associated with reference signals improves network performance.

PDCCH monitoring occasion information indicator

BWP handover information indicator

Scell operation indicator

6. Spatial information.

QCL information indicator

In a specific example, there are M functions or configurations. The bit width of the functionality indicator may be obtained based on log 2 (M). To indicate the 8 functions listed above, 3 bits are required. For example, "000" indicates "awake", "001" indicates PDCCH monitoring occasion information, and the like.

In some embodiments, the functionality indicator is designed to indicate the functionality of all blocks in the DCI or the functionality of one or more blocks in the DCI. When the functionality indicator indicates the functionality of all blocks in the DCI, all blocks in the DCI payload share the same functionality indicator. It may reduce the payload and enhance performance. When the functionality indicator indicates the functionality of one or more blocks in the DCI, the blocks in the DCI payload may have a separate indicator. It provides more flexibility.

In some embodiments, the trigger status or functionality indicator of the data block is indicated by downlink control signaling. In some embodiments, the functionality indicator of the trigger status or data block is indicated by higher layer signaling. In an example, the higher layer signaling includes RRC signaling or MAC CE.

Bit width

In some embodiments, the bit width of each block is related to at least one of: at least one higher layer parameter, a functionality indicator, a RNTI (Radio network temporary identifier) or a UE-ID (UE specific identifier). In an example, the higher layer parameter indicates the functionality of the DCI, or one or more data blocks or trigger states in the DCI payload. In an example, the at least one higher layer parameter indicates a bit width of the DCI, or one or more blocks or trigger states in the DCI. In an example, the at least one higher layer parameter comprises RRC signaling or MAC CE. The bit width indicated by the at least one higher layer parameter is a maximum value. In some embodiments, the functionality indicator is included in RRC signaling, MAC CE, or DCI. In some embodiments, the RNTI comprises a PS-RNTI. In some embodiments, the RNTI does not include C-RNTI, CS-RNTI, MCS-C-RNTI, TC-RNTI, SP-CSI-RNTI, P-RNTI, SI-RNTI, RA-RNTI, TC-RNTI, SFI-RNTI, INT-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI.

In some embodiments, the UE is instructed to at least one of: i) a position in the DCI payload, or ii) a mapping rule. In some embodiments, the control signaling is specified by a UE set specific PDCCH. The UE needs to know how to interpret DCI after PDCCH decoding, or the UE needs to know what information is indicated from the BS. Items i) to ii) will be discussed in detail below.

i) Location in DCI payload. The UE is configured with information indicating which part of the DCI payload is used to transmit its information. The position in the DCI payload may be a starting position in the DCI payload, or an ending position in the DCI, or a block index. For example, assuming a payload of { b1, b2, b3, b4, b5, b6} (i.e., 6 bits in DCI), the UE is configured with a starting position of 3 and a bit width of 2. In this case, bits b3 and b4 are used to transmit information to this particular UE. In another example, DCI content block #1, block #2, block #3, block #4, block # 5. When a UE is configured with a block index of 3, then block #3 is used to transmit information to this UE.

ii) mapping rules. In this case, the UE is configured with different trigger states. The mapping rule relates to the number of UEs indicated by the same DCI and/or the number of trigger states per UE. In this case, the UE0 is indicated by a list of multiple trigger states { t1.. TN } indicative of the UE1 to the UE n.

Starting position

The starting position of the block is determined by the higher layer parameters of one or more UEs that are configured with the block. The UEs configured with the same DCI payload are determined by higher layer parameters, traffic type, UE-ID, RNTI, or UE assistance information.

Example 3

In some embodiments, the control signaling may include:

i) field-1: one of the configuration information 1 to 9 indicators. In some embodiments, field-1 includes a configuration information-1 indicator.

ii) field-other: other configuration information indicators

In some embodiments, the bit field carrying configuration information 1 is the first or last field in the DCI format bit field, or before/after the bit field having a predetermined size. If field-1 indicates that the UE configuration parameters have not changed, the corresponding field-other values are 0 or padding bits. If field-1 indicates an entry into a sleep indicator or a reserved entry, the corresponding field-other value is 0 or a padding bit. Alternatively, if field-1 indicates that the UE configuration parameters have not changed, or a sleep indicator has been entered, or an entry has been reserved, the size of the bit field in field-others is W1. Otherwise, field-bit field among others is of size W2. W1 and W2 are non-negative integers and W1 is less than W2.

Example 1: the information carried in the control signaling includes:

field-1:

block-1-1, block-1-2, … …, block-1-N; -B W bits, functional 1 or 2 indicators, wherein B and W are natural numbers.

Block-1-i is associated with block-m-j, where i and j are positive numbers, and 1 ≦ m ≦ N. If the value of block-1-i is a value of-1, then block-m-j is all zeros or padding bits. If the value of block-1-i is a value of-1, the bit width of block-m-j is W1. If the value of block-1-i is a value of-2, the bit width of block-m-j is W2. W1 and W2 are non-negative, and W1 is not greater than W2.

Example 2: the information carried in the control signaling includes:

field-1:

l bits configuration information 1

Field-other:

-Block 1, Block 2, … …, Block B-other configuration indicators

In this case, the UE is indicated by field-1 to go to sleep indicator, field-the corresponding block in the other is zero or a padding bit.

Information jointly coded in block/DCI

In some embodiments, the configuration information for the UE is jointly encoded in a data block. In some embodiments, the configuration information for one or more UEs is jointly encoded in DCI.

Indicator of a subset of a set of UEs

In some embodiments, the control signaling includes an indicator of a subset of the set of UEs. The control signaling is sent to one or more UEs. For example, in case that control signaling is used for a plurality of UEs, when the subset field of the control signaling is value _1, a data block or the control signaling is used to inform configuration parameters of a subset of the set of UEs. When the subset field of the control signaling is value _2, the data block or the control signaling is used to inform the configuration parameters of other subsets of the set of UEs.

In some embodiments, the control signaling comprises a CSI request, or the control signaling associates with a CSI request. In some embodiments, the SRS request is included in the control signaling. Alternatively, the control signaling is associated with the SRS request.

In some embodiments, the initial value of DM-RS of PS-PDCCH is related to PS-RNTI. In some embodiments, the number of OFDM symbols occupied by the CORESET of the PDCCH with control signaling is 1 or 2.

In some embodiments, the REG mapping pattern for the first set of PDCCH candidates does not include interleaving. In some embodiments, the search space of the PDCCH with control signaling is a common search space.

In some embodiments, a data block field with all zero values indicates at least one of: 1) an enter sleep indicator; 2) configuration information 2 identical to the predefined timing; 3) the same configuration information 3 as the predefined timing; 4) the same configuration information 4 as the predefined timing; 5) the same configuration information 5 as the predefined timing; 6) the same configuration information 6 as the predefined timing; 7) the same configuration information 7 as the predefined timing; 8) the same configuration information 8 as the predefined timing; 9) the same configuration information 9 as the predefined timing. In some embodiments, the predefined timing is when the first set of PDCCH candidates is received or transmitted or decoded.

In some embodiments, the second set of PDCCH candidates cannot occupy predefined resources. The predefined resource may be configured by the RRC for the first set of PDCCH candidates.

In some embodiments, the configuration of the first set of PDCCH candidates is for each cell or carrier.

Timing of PDCCH with control signaling

There are two different offsets, including an offset between the monitoring occasions and DRX on for the first set of PDCCH candidates provided by the corresponding search space, and an offset between the monitoring occasions for the first set of PDCCH candidates and the second set of PDCCH candidates provided by the corresponding search space.

In some embodiments, the offset between the monitoring occasion and DRX on for the first set of PDCCH candidates provided by the corresponding search space is associated with or determined by: i) UE capability, ii) PDSCH processing capability, iii) PUSCH preparation time, or iii) BWP handover time.

In some embodiments, the offset between the monitoring occasions for the first set of PDCCH candidates and the second set of PDCCH candidates provided by the corresponding search space is associated with or determined by: i) UE capability, ii) PDSCH processing capability, iii) PUSCH preparation time, or iii) BWP handover time.

In some embodiments, the monitoring occasions for the first set of PDCCH candidates or the search space for the first set of PDCCH candidates are periodic. In one example, the monitoring occasion for the first set of PDCCH candidates or the periodicity of the search space for the first set of PDCCH candidates is a multiple of the periodicity of the DRX cycle. In another example, the monitoring occasion for the first set of PDCCH candidates or the periodicity of the search space for the first set of PDCCH candidates is less than the periodicity of the DRX cycle. The monitoring occasion of the first set of PDCCH candidates or the periodicity of the search space of the first set of PDCCH candidates is a multiple of the maximum periodicity of the search space of the second set of PDCCH candidates. The monitoring occasion of the first set of PDCCH candidates or the periodicity of the search space of the first set of PDCCH candidates may be a multiple of the minimum periodicity of the search space of the second set of PDCCH candidates.

In some embodiments, the monitoring occasions for the first set of PDCCH candidates may be after the inactivity timer starts. The monitoring occasions of the first set of PDCCH candidates are distinguished from the monitoring occasions of the second set of PDCCH candidates in the time domain and they are defined at different time occasions. The first set of PDCCH candidates has a higher priority in mapping order than the second set of PDCCHs. Thus, if the timing of the first set of PDCCHs collides or overlaps with the second set of PDCCHs, the first set of PDCCH candidates is transmitted first.

In some embodiments, the number of blind decodings for the first set of PDCCH candidates is 1. In some embodiments, the beam information or antenna port quasi co-location information of the second set of PDCCH candidates is associated with or determined by the first set of PDCCH candidates. For example, beam information or antenna port quasi co-location information for the second set of PDCCHs is indicated by the first set of PDCCH candidates. In another example, if the second set of PDCCHs and the first set of PDCCH candidates overlap in certain domains, beam information or antenna port quasi-co-location information of the second set of PDCCHs is associated with the first set of PDCCH candidates. The domain includes CORESET, search space, time resources, or frequency resources.
