Background

The ultra-wide bandwidth high frequency band (i.e. millimeter wave communication) becomes an important direction for the development of future mobile communication, and attracts the attention of the global academia and industry. In particular, the advantages of millimeter waves are becoming more and more attractive when the increasingly congested spectrum resources and physical networks are now heavily accessed, and corresponding standardization work is being developed in many standards organizations, such as IEEE (Institute of Electrical and Electronics Engineers), 3GPP (3rd Generation Partnership Project). For example, in the 3GPP standard group, high-band communication will become an important innovation point of 5G New Radio Access Technology (New RAT, New 5G Radio Access Technology) by virtue of its large bandwidth.

In the existing 5G communication system, because the limitation of analog beam scheduling needs to be considered, only one analog beam dimension resource can be effectively scheduled from the transmission of the control channel, the data channel and the reference signal. However, in actual transmission, since flexible scheduling needs to be supported, more than one control channel, data channel, and reference signal need to be simultaneously transmitted or received to maximize transmission performance. The above technical problem is not solved in the prior art to support simultaneous transmission and reception under multiple control channels, data channels and reference signals.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

Fig. 1 is a schematic diagram of a hybrid precoding (hybrid analog-digital beamforming) transceiver according to the present invention. The system transmitting end and the system receiving end are configured with a plurality of antenna units and a plurality of radio frequency links. Wherein each rf chain is interconnected to an antenna array element (not excluding a partial connection scenario), and each antenna element has a digital keying phase shifter. By means of loading different phase shift quantities on signals of each antenna unit, the high-band system realizes Beamforming (Beamforming) at an analog end. In particular, in a hybrid beamforming transceiver, there are multiple streams of radio frequency signals. Each signal stream is loaded with precoding AWV (antenna weight vector) through a digital keying phase shifter and is sent to a high-frequency-band physical propagation channel from a multi-antenna unit; at the receiving end, the radio frequency signal streams received by the multiple antenna units are weighted and combined into a single signal stream, and after radio frequency demodulation at the receiving end, the receiver finally obtains a plurality of received signal streams, and the received signal streams are sampled and received by a digital baseband.

The UE (user equipment) end receives the channel characteristic hypothesis of the control channel resource set configured by the base station end, and the control channel resource set is composed of a first type search space, a second type search space, or a first type and a second type search space. Wherein, the channel characteristic hypothesis acts on the second type search space, and the control channel resource set refers to a downlink control channel resource set. For the description, in the embodiment of the present invention, the UE is also referred to as a first communication node, and the base station is also referred to as a second communication node.

And, the first type of search space is a common search space, or a beam recovery search space. Specifically, the common search space, including but not limited to:

1) type0-PDCCH (Physical Downlink Control Channel) common search space;

2) type0A-PDCCH common search space;

3) type1-PDCCH common search space;

4) type2-PDCCH common search space;

5) type3-PDCCH common search space.

The first type of search space does not require explicit configuration of channel state information, but rather determines the channel characteristic hypotheses for the first type of search space by predefined criteria. For example, a corresponding relationship between a first search space and a downlink reference signal (e.g., a synchronization reference signal SS/PBCH) is configured, and when the UE desires to receive the search space, it is necessary to assume a channel characteristic assumption according to the corresponding relationship, that is, determine the receiving beam information at the UE end.

For the beam recovery search space, the monitoring window starts from the time when the first communication node transmits a PRACH (Physical Random Access Channel) plus an offset time until the first communication node receives a Channel characteristic assumption reconfiguration for a downlink control Channel, and the corresponding Channel characteristic assumption is based on a downlink reference signal associated with the PRACH reported by the UE.

The second type of search space refers to a user-specific search space, and the channel characteristic assumption information of the search space is determined by explicit configuration signaling of the base station. Further, the channel characteristic assumption is: quasi co-location (QCL), or spatial quasi co-location (spatial QCL), or transport configuration indication status (TCI). Further, the channel characteristic assumption is used for indication of the beam.

The reference signal of the embodiment of the invention at least comprises one of the following components:

1) channel state information reference signal (CSI-RS)

2) Channel state information interference measurement signal (CSI-IM)

3) Demodulation reference signal (DMRS)

4) Downlink demodulation reference signal (DL DMRS)

5) Uplink demodulation reference signal (UL DMRS)

6) Channel Sounding Reference Signal (SRS)

7) Phase tracking reference signal (PT-RS)

8) Random access channel signal (RACH)

9) Synchronization Signal (SS)

10) Synchronizing signal block (SS block)

11) Primary Synchronization Signal (PSS)

12) Auxiliary synchronizing signal (SSS)

The beam may be a resource (e.g., transmit-side spatial filter, receive-side spatial filter, transmit-side precoding, receive-side precoding, antenna port, antenna weight vector, antenna weight matrix, etc.), and the beam sequence number may be replaced with a resource index (e.g., reference signal resource index), because the beam may be bound to some time-frequency code resources for transmission. A beam may also be a transmission (transmit/receive) mode; the transmission means may include spatial multiplexing, frequency/time domain diversity, etc.

In addition, the base station can perform Quasi-co-location (Quasi co-location) configuration for the two reference signals and inform the user terminal to describe the channel characteristic assumption. The parameters related to the quasi-co-location at least comprise Doppler expansion, Doppler translation, delay expansion, average delay, average gain and space parameters; the spatial parameters may include spatial receiving parameters, such as an angle of arrival, spatial correlation of receiving beams, average delay, and correlation of time-frequency channel response (including phase information).

First embodiment

Referring to fig. 2, fig. 2 is a flowchart of a channel configuration method according to a first embodiment of the present invention, including:

s201, receiving a second channel characteristic hypothesis of a control channel resource set configured by a second communication node; the control channel resource set is composed of a first type search space and/or a second type search space; the second channel characteristic hypothesis is used for a configuration of control channel resources within the second type of search space;

and S202, receiving the control channel resource sent by the second communication node according to the second channel characteristic hypothesis.

The set of control channel resources refers to a set of downlink control channel resources. The first channel characteristic assumption of the first type of search space in this embodiment may be determined by a predefined criterion.

In some embodiments, the first type of search space comprises a common search space and/or a beam recovery search space.

In some embodiments, the second type of search space comprises a user-specific search space.

In some embodiments, the second channel characteristic hypothesis includes at least one of quasi co-location, spatial quasi co-location, transmission configuration indication status.

In some embodiments, when the first type of search space and the second type of search space satisfy the first trigger condition, at least one of the following is further included:

receiving or monitoring a first type of search space;

the second channel characteristic hypothesis is determined by the first channel characteristic hypothesis of the first type of search space;

the second channel characteristic hypothesis is the same as the first channel characteristic hypothesis of the first type of search space;

the second channel characteristic hypothesis is the same as the first channel characteristic hypothesis of a search space with a specific search space index in the first type of search space;

the first channel characteristic hypothesis and the second channel characteristic hypothesis are the same as a first channel characteristic hypothesis of a search space having a specific search space index in the first type of search space;

a second type of search space is received or monitored when the second channel characteristic hypothesis is the same as the first channel characteristic hypothesis.

In some embodiments, the first type of search space and the second type of search space satisfy a first trigger condition, the first trigger condition including:

the first type of search space and the second type of search space are in the same OFDM (Orthogonal Frequency Division Multiplexing) symbol; the first type of search space and the second type of search space are in the same time slot; the first type of search space and the second type of search space are in the same resource block; the monitoring windows related to the first type of search space and the second type of search space are overlapped; at least one of the first type of search space and the second type of search space are simultaneously active. Wherein the specific search space index comprises one of: the lowest index order number, the highest index order number, or a particular search space index order number.

In some embodiments, the first type of search space is from the same set of control channel resources as the second type of search space. For different control resource sets, different carriers, and the case of inconsistent channel characteristic assumptions between the first type of search space and the second type of search space under different BWPs (bandwidth parts) can be disregarded; alternatively, the detection behavior of the channel characteristics between the first type search space and the second type search space under different BWPs assuming different time differences may be performed by the first communication node.

Fig. 3 is a diagram illustrating a channel characteristic assumption validation condition of a PDCCH according to the present invention. UE-SS is denoted UE-specific search space, i.e. search space of the second type of embodiments of the present invention, and CSS is denoted common search space, i.e. search space of the first type of embodiments of the present invention. The base station configures the channel characteristic hypothesis of the second type of search space UE-SS through the TCI, and the first type of search space has a corresponding relation with the previously sent SSB through default hypothesis or configuration. Here, it is assumed that the TCI of the UE-SS is configured as SSB2, and the period of the UE-SS is 2 slots. Therefore, on slot- { n +1} and slot- { n +3}, the UE-SS and the CSS face the problem of simultaneous transmission, and the embodiment of the invention requires that the CSS has higher priority relative to the UE-SS, and the UE-SS needs to obey the channel characteristic assumption of the CSS in collision. Thus, at slot- { n +3}, the UE-SS needs to receive SSB-2 according to CSS-4. The first-type search space and the second-type search space may be from the same control resource set or may be from different control resource sets.

In some embodiments, when the first type of search space and the second type of search space satisfy the first trigger condition, or the associated windows overlap or partially overlap, the method further includes:

receiving or monitoring a first type of search space of the lowest, highest or specific index under a preset index;

the second channel characteristic hypothesis is determined by the first type of channel characteristic hypothesis with the lowest, the highest or a specific index under a preset index;

the second channel characteristic hypothesis is the same as the first channel characteristic hypothesis with the lowest, the highest or a specific index under a preset index;

the second channel characteristic hypothesis is the same as a channel characteristic hypothesis of a search space having the lowest search space index among search spaces of the first type having the lowest, highest, or specific index under the preset index.

In some embodiments, pre-setting the index includes: at least one of a carrier index, a BWP index, a control channel resource set index, and a control channel resource index. The preset index may also be referred to as a class V index.

In some embodiments, when the first type of search space and the second type of search space satisfy the second trigger condition, the method further includes:

a second type of search space is detected or received.

In some embodiments, the first type of search space and the second type of search space satisfy a second trigger condition, the second trigger condition including:

the second type of search space is different from the first type of search space in OFDM symbols; the second type of search space and the first type of search space are in different time slots; the second type of search space and the first type of search space are in different resource blocks; the second type of search space is at a different time than the first type of search space; the second type of search space is at least one of different carriers than the first type of search space.

Optionally, when the second search space and the first search space are transmitted in an OFDM symbol, or a slot, or an RB (resource block ), or a carrier and collide with each other, the second search space may be selected not to be detected or not to be received. Optionally, the second type of search space is monitored when the first type of search space is not monitored or is not in the monitoring window associated with the first type of search space. The first type of search space may be in a monitoring state or in a monitoring window associated therewith.

Optionally, when the first type of search space is a beam recovery search space, the monitoring window starts from a time when the first communication node transmits the PRACH plus an offset time until the first communication node receives a channel characteristic assumption reconfiguration for the downlink control channel.

Fig. 4 is another diagram illustrating a condition for assuming validity of channel characteristics of a PDCCH according to the present invention. In the case of considering multiple carriers, namely, Primary cell and secondary cell, when UE-SS and CSS transmit at the same time, the channel feature assumption of the search space of the Primary cell is preferentially obeyed, and then, under the first type of search space and the second type of search space in the Primary cell, the channel feature assumption of the first type of search space is preferentially selected. Therefore, in this case, it is necessary to receive the UE-SS of the secondary cell, subject to the channel characteristic assumption of the CSS under the Primary cell.

The embodiment provides a channel configuration method, which receives a second channel characteristic hypothesis of a control channel resource set configured by a second communication node; the control channel resource set is composed of a first type search space and/or a second type search space, and the second channel characteristic hypothesis is used for the configuration of the control channel resources in the second type search space; and receiving the control channel resource sent by the second communication node according to the second channel characteristic hypothesis.

Seventh embodiment

A seventh embodiment of the present invention provides a channel configuration method, which is applied when a first type of search space and a second type of search space satisfy a first trigger condition, and specifically includes the following steps:

when the first search space and the second search space are in the same OFDM symbol, or in the same slot, or in the same Resource Block (RB), or when the associated monitoring windows coincide, or are simultaneously valid, that is, the first search space and the second search space satisfy the first trigger condition, if the channel characteristics of the first search space and the second search space are assumed to be different, it means that the base station needs to transmit using different transmit beams, and the UE needs to receive using different receive beams. However, when the base station side can only support simultaneous transmission of one beam, or the UE side can only support simultaneous reception of one beam, the requirements and capabilities of monitoring are contradictory, and therefore, it is necessary to correct the channel characteristic assumptions between different search spaces, and optionally, at least one or a combination of the following is performed:

#4 the second channel characteristic hypothesis for the second type of search space is to be the same as the first channel characteristic hypothesis for the search space having the lowest, highest, or particular search space index in the first type of search space; or

#5 the channel characteristic hypotheses in the first-type search space and the second-type search space, i.e., the first channel characteristic hypothesis and the second channel characteristic hypothesis, respectively, are to be the same as the first channel characteristic hypothesis for the search space having the lowest, highest, or particular search space index in the first-type search space; or

#6 the second type of search space is received or monitored when the second channel characteristic hypothesis of the second type of search space is the same as the first channel characteristic hypothesis of the first type of search space.

The above scheme is applicable to the case where the first type of search space and the second type of search space are from the same set of control channel resources. However, for the case where the channel characteristics between the first type search space and the second type search space under different BWPs are assumed to be inconsistent without considering different sets of control resources, different carriers; alternatively, the detection behavior of different channel characteristics between different sets of control resources, different carriers, and first and second search spaces under different BWPs may be assumed to be different at the same time by the first communication node.

When the first search space and the second search space are in the same OFDM symbol, or the same slot, or the same RB, or the same overlap of the associated monitoring windows, or are simultaneously valid, that is, when the first search space and the second search space satisfy the first trigger condition, the method may include:

#1 receives or monitors a first type of search space; alternatively, the first and second electrodes may be,

#2 receives or monitors a first type of search space for a lowest, highest, or particular index under a preset index; alternatively, the first and second electrodes may be,

#6 the channel characteristic hypotheses for the first-type search space and the second-type search space may also not affect each other.

Wherein, the preset index is composed of one or a combination of the following components: carrier index, BWP index, control channel resource set index, control channel resource index.

Optionally, the simultaneous validity referred to in this embodiment is valid at the same time, and includes a case where time domains in different carrier spacings and different numerologies (digital numerology) partially overlap.

In addition, in this embodiment, it may be further specified that the UE obeys a behavior criterion that the second type search space is not detected or not received when the second type search space collides with the first type search space on an OFDM symbol, or a slot, or an RB, or a carrier; or, the second type of search space is monitored when the first type of search space is not monitored or is not in the monitoring window associated with the first type of search space. However, the second type search space and the first type search space detect or receive the second type search space in different OFDM symbols, or different slots, or different RBs, or different time instants or different carriers, that is, when the first type search space and the second type search space satisfy the second trigger condition.

Optionally, the first type of search space is in a monitoring state or in a monitoring window associated therewith.

Optionally, when the first type of search space is a beam recovery search space, the monitoring window starts from a time when the first communication node transmits the PRACH plus an offset time until the first communication node receives a channel characteristic assumption reconfiguration for the downlink control channel.

Ninth embodiment

A ninth embodiment of the present invention provides a channel configuration method, which is applied to channel configuration under a PUCCH condition, and specifically includes the following steps:

for an uplink control channel, a method for a base station to perform channel characteristic assumption for a UE specifically includes: receiving a channel characteristic hypothesis of an uplink control channel resource configured by a second communication node;

and sending the uplink control channel resource to the second communication node according to the channel characteristic hypothesis of the uplink control channel resource.

Optionally, when different N uplink control channel resources are simultaneously transmitted, the N uplink control channel resources obey a setting mode of a channel characteristic assumption that is at least one of the following:

#1 channel characteristic assumption of uplink control channel resource of lowest, highest, or particular uplink control channel resource index;

#2 channel characteristic assumption of uplink control channel resources under the carrier or primary carrier of the lowest or highest carrier index;

#3 channel characteristic assumption of the uplink control channel resource under BWP indexed lowest or highest BWP or activated BWP;

#4 channel characteristic assumption of uplink control channel resource of lowest or highest or specific uplink control channel resource index under the carrier or primary carrier of lowest or highest carrier index;

#5 channel characteristic assumption of uplink control channel resource of lowest or highest or specific uplink control channel resource index under BWP of lowest or highest BWP index or active BWP;

#6 carrier or main carrier with lowest or highest carrier index, and/or BWP with lowest or highest BWP index or channel characteristic assumption of uplink control channel resource under active BWP;

#7 carrier or primary carrier with lowest or highest carrier index, and/or BWP with lowest or highest BWP index or channel characteristic assumption of uplink control channel resource with lowest or highest or specific uplink control channel resource index under active BWP.

The specific index refers to an index of a predefined specific index number, for example, when the uplink control channel resource index is 0 or 127.

The primary carrier is also referred to as a primary cell, or a primary cell under a primary PUCCH group.

Optionally, the step of simultaneously sending different N uplink control channel resources specifically includes: different N uplink control channel resources are valid at the same OFDM symbol, or the same slot, or the same RB, or the same overlap of the associated monitoring windows, or at the same time.

The channel characteristic assumption may include spatial relationship information, or spatial relationship, among others.

Optionally, when the uplink reference signal, the uplink data channel, or the uplink control channel scheduled by the common search space has a higher priority than the uplink reference signal, the uplink data channel, or the uplink control channel scheduled by the dedicated search space of the user.

Optionally, the channel characteristic assumption of the low priority reference signal or channel may be determined or the low priority reference signal or channel may not be transmitted at the same time for transmission, or at the same RB, or at the same OFDM symbol, or the same slot, or the same BWP, or the same carrier.

Fig. 10 is a diagram illustrating a channel characteristic assumption validation rule of a PUCCH according to the present invention. When the UE is configured with a Primary PUCCH group and a Secondary PUCCH group, the spatial relationship information of the Primary PUCCH group is preferentially obeyed under the collision of PUCCH resources PUCCH-P2 under the Primary PUCCH group and PUCCH-S2 under the Secondary PUCCH group at the time n + 1. By the method, the PUCCH resource scheduling which is relatively flexible can be realized by using the specified priority and the slave method under the condition of considering both the UE and the base station.

Tenth embodiment

A tenth embodiment of the present invention provides a channel power control method.

A method for determining power control facing to an uplink shared channel (PUSCH) is applied to a UE end and comprises the following steps:

receiving a first type of MAC-CE signaling sent to a UE end by a base station end;

and determining the power control parameter of the PUSCH according to the first type of MAC-CE signaling.

Wherein, the determination method comprises at least one of the following steps:

the open loop power control parameter of #1PUSCH is determined by the first type MAC-CE signaling;

reference signals of path loss PL of #2PUSCH are determined by first-type MAC-CE signaling;

#3 the closed loop power control index for the PUSCH is determined by the first type of MAC-CE signaling;

#4 resets the closed loop power control value of the PUSCH.

The open-loop power control parameter may be composed of alpha and a target power p 0.

However, the semi-persistent SRS associated with PUSCH transmission may be activated by MAC-CE signaling and carry spatial relationship information for the SRS. Further, the first type of MAC-CE signaling activates or deactivates the semi-persistent SRS reference signal, or configures the spatial relationship of the associated SRS, i.e., the same signaling as activating the semi-persistent SRS.

Further, the SRS is used in a non-codebook mode or a codebook mode, and specifically, the non-codebook mode and the codebook mode are transmission modes for the PUSCH.

Further, if the MAC-CE activation signaling of SRS is received and the usage of SRS is non-codebook mode or codebook mode, the closed loop power control value associated with PUSCH needs to be reset (when PUSCH uses closed loop power control in accumulation mode).

Specifically, the first type of MAC-CE signaling specifies an element index in an open loop power control parameter set, and is associated with an SRI code value in DCI, or the first type of MAC-CE signaling carries open loop power control parameter values associated with an SRI field in DCI; or, the first type of MAC-CE signaling specifies an element index in a reference signal set of the path loss PL, which is associated with an SRI code value in the bearer DCI, or the first type of MAC-CE signaling carries the reference signal index of the path loss PL associated with the SRI field in the bearer DCI; or, the first type of MAC-CE signaling carries a closed-loop power control index associated with the SRI code value in the DCI.

Furthermore, the uplink transmission power of the associated PUSCH may be controlled by:

the open-loop power control parameter of #1PUSCH is determined by an element index in an open-loop power control parameter set associated with an SRI code value in DCI configured by RRC; alternatively, the first and second electrodes may be,

#2 the reference signal for the pathloss PL for the PUSCH is determined by the downlink reference signal associated with the spatial parameters of the semi-persistent SRS associated with the SRI in the DCI; alternatively, the first and second electrodes may be,

and the open-loop power control parameter of the #3PUSCH is determined by the closed-loop power control index associated with the SRI code value in the DCI configured by RRC.

Fig. 11 is a schematic diagram of a signaling format of a MAC-CE configured power control parameter according to the present invention. In an explicit form, the MAC-CE configuration corresponds to the power control parameters in the SRI values in the DCI, i.e., the values of the target powers P0 and alpha, the reference signal index, and the closed-loop power control index. If only one SRS is involved, the DCI does not explicitly carry the SRI, and the corresponding parameter needs to be configured, so that the SRI facing the default indication is 0.

Fig. 12 is another schematic diagram of a signaling format of a MAC-CE configured power control parameter according to the present invention. In the RRC signaling, a parameter resource set for uplink power control has been configured, in which case, corresponding elements are indicated in the parameter resource set described in the MAC-CE signaling to implement configuration of power control parameters. Specifically, for each SRI, a corresponding P0 and alpha set index (i.e., an open-loop power control parameter set, which is a set configured at RRC and carries a plurality of the open-loop power control parameter sets), PL reference signal resource index, and closed-loop power control index are configured.

In summary, according to the configuration or the predetermined channel configuration method or channel power control method, coordination is performed among multiple control channels, data channels, and reference signals, so as to effectively implement simultaneous scheduling of multiple control channels, data channels, and reference signals on the premise of ensuring the support capability of the base station and the user side, thereby significantly improving the system performance.
