Technical Field

The embodiment of the application relates to the field of communication, and more particularly, to a wireless communication method, terminal equipment and network equipment.

Background

In order for the network device to perform reasonable scheduling, the terminal device needs to feed back downlink channel state information (Channel State Information, CSI) so that the network device determines scheduling information of the terminal such as the number of transmission layers, the precoding matrix, the transmission beam, the modulation coding scheme and the like. Specifically, CSI reporting by the terminal device is performed based on CSI reporting configuration (CSI-ReportConfig) indicated by the network device, and uplink resources used for reporting CSI by the terminal device, downlink reference signals and measurement subbands used for performing CSI measurement are indicated by the CSI reporting configuration.

The terminal equipment reports one CSI for each CSI reporting configuration, wherein the CSI is calculated based on channel measurement resources and interference measurement resources configured by a network and is used for obtaining channel information of a Transmission point/receiving point (TRP). In a multi-TRP transmission scheme based on multi-downlink control information (Downlink Control Information, DCI), two TRPs independently schedule physical downlink shared channels (Physical Downlink Shared Channel, PDSCH) of the same terminal device, and corresponding PDSCH physical resources may be fully overlapping, partially overlapping or non-overlapping. Under the condition of different resource overlapping, due to different corresponding CSI of interference, how to measure and report the CSI is a problem to be solved urgently.

For better understanding of the embodiments of the present application, the downlink incoherent transmission related to the present application is described.

Non-coherent Transmission based on downlink and uplink of a plurality of Transmission/reception points (TRPs) is introduced in the NR system. The backhaul (backhaul) connection between the TRPs may be ideal or non-ideal, and information interaction between the TRPs under the ideal backhaul may be performed rapidly and dynamically, and information interaction between the TRPs under the non-ideal backhaul may be performed only in a quasi-static manner due to a larger time delay. In downlink incoherent transmission, multiple TRPs may use different control channels to independently schedule multiple physical downlink shared channels (Physical Downlink Shared Channel, PDSCH) of one terminal for transmission, or may use the same control channel to schedule transmission of different TRPs, where data of different TRPs uses different transmission layers, which can only be used in the case of ideal backhaul.

For downlink transmissions scheduled using multiple physical downlink control channels (Physical Downlink Control Channel, PDCCH), the scheduled PDSCH may be transmitted in the same time slot or in different time slots. The terminal needs to support simultaneous reception of PDCCH and PDSCH from different TRPs. When the terminal feeds back Acknowledgement (ACK)/negative Acknowledgement (Negative Acknowledgement, NACK) and channel state information (Channel State Information, CSI), the ACK/NACK and CSI may be fed back to different TRP (e.g. a in fig. 2) for transmitting the corresponding PDSCH, or may be reported to one TRP (e.g. B in fig. 2) in a combined manner. The former can be applied to both ideal and non-ideal backhaul scenarios, and the latter can only be applied to ideal backhaul scenarios. The downlink control information (Downlink Control Information, DCI) transmitted by different TRPs and used for scheduling PDSCH can be carried by different control resource sets (Control Resource Set, CORESET), i.e. the network side configures a plurality of CORESETs, each TRP is scheduled by adopting a respective CORESET, i.e. different TRPs can be distinguished by the CORESET. For example, the network device may configure one CORESET group index for each CORESET, with different indices corresponding to different TRPs. When the terminal feeds back the CSI, it is necessary to feed back the CSI corresponding to each TRP. The CSI includes content such as Rank Indication (RI), precoding matrix Indication (Precoding Matrix Indicator, PMI), channel quality Indication (Channel Quantity Indicator, CQI), etc., and may be used for scheduling downlink transmission by the respective TRP.

For better understanding of the embodiments of the present application, description is made on the downlink CSI reporting related to the present application.

In order for the network device to perform reasonable scheduling, the terminal needs to feed back downlink channel state information CSI so that the base station determines scheduling information of the terminal such as the number of transmission layers, the precoding matrix, the transmission beam, the modulation coding mode and the like. Specifically, CSI reporting by the terminal is performed based on CSI reporting configuration indicated by the network device, and uplink resources used for reporting CSI by the terminal, downlink reference signals and measurement subbands used for performing CSI measurement are indicated by the CSI reporting configuration, where CSI reporting configuration (CSI-ReportConfig) may be shown in fig. 3. Wherein the resources for CSI measurement comprise two types of resources: channel measurement resources (Channel Measurement Resource, CMR) and interference measurement resources (Interference Measurement Resource, IMR). Specifically, the CMR may be a number of Non-zero power channel state information Reference signals (NZP-CSI-RS) or synchronization Signal blocks (Synchronization Signal Block, SSB), and the interference measurement resources may be channel state information interference measurements (Channel State Information Interference Measurement, CSI-IM) and/or NZP-CSI-RS. Meanwhile, the base station can instruct the terminal to measure the CSI on which sub-bands through the CSI reporting configuration, and the terminal only needs to measure the signals and the interference on the sub-bands and feeds back the CSI corresponding to the sub-bands. Each CSI report configuration corresponds to one CSI report, and each CSI report may include different information such as CRI, RI, PMI, CQI. Specifically, which content/information is contained in the CSI is determined by reporting quality information (reporting quality) in the CSI reporting configuration.

Note that SSB may also be referred to as a synchronization signal/physical broadcast channel block (synchronization signal/physical broadcast channel block, SS/PBCH block).

At present, a terminal reports one piece of CSI for each piece of CSI reporting configuration, wherein the CSI is obtained by calculation based on channel measurement resources and interference measurement resources configured by a network and is used for obtaining channel information of one TRP. For example, the terminal may obtain the independent CSI of TRP1 by CSI reporting configuration 1 and obtain the independent CSI of TRP2 by CSI reporting configuration 2. In the multi-TRP transmission scheme based on multi-DCI, two TRPs independently perform PDSCH scheduling of the same terminal device, and corresponding PDSCH physical resources may be completely overlapped, partially overlapped or non-overlapped. In case of different resource overlaps, the corresponding CSI will also be different due to the interference. The existing CSI reporting scheme cannot support reporting CSI under different resource overlapping conditions, and CSI obtained by the network device is not necessarily optimal CSI under the current scheduling condition, so that the performance of multi-TRP transmission is affected.

Based on the above problems, the present application proposes a scheme for configuring resource overlapping type information, which can instruct a terminal device to measure CSI under different PDSCH resource overlapping assumptions through the resource overlapping type information, so as to flexibly schedule PDSCH under different resource overlapping conditions, and support multi-TRP simultaneous transmission based on multi-DCI. After obtaining the CSI corresponding to different resource overlapping types, the network device may use the corresponding CSI for the scheduled PDSCH according to the current scheduling result, so as to obtain higher throughput.

The technical scheme of the present application is described in detail below through specific embodiments.

Fig. 4 is a schematic flow chart of a method 200 of wireless communication according to an embodiment of the present application, as shown in fig. 4, the method 200 may include at least some of the following:

s210, the network equipment sends a first CSI reporting configuration to the terminal equipment, wherein the first CSI reporting configuration at least comprises resource overlapping type information;

s220, the terminal equipment receives the first CSI reporting configuration;

and S230, the terminal equipment performs CSI measurement according to the resource overlapping type information.

In the embodiment of the present application, the resource overlap refers to resource overlap of PDSCH. When CSI is measured, a transmission assumption (corresponding to PDSCH scheduled by the network device) is needed, and it may be assumed that PDSCH is overlapped or not overlapped, and the corresponding CSI measurement method is different, after CSI measurement, the CSI measurement result may be reported to the network device, where CSI reporting is used for PDSCH transmission.

That is, in the embodiment of the present application, the resource overlapping type information is used to instruct the terminal device to perform CSI measurement according to the indicated resource overlapping type (overlay type).

In some embodiments, the resource overlap type information is used to indicate at least one of non-overlapping, partially overlapping, fully overlapping.

In some embodiments, the resource overlap type information is used to indicate at least one of non-overlapping, overlapping.

In some embodiments, the resource overlap type information in the first CSI reporting configuration is the same as the resource overlap type information in the second CSI reporting configuration; the second CSI reporting configuration is a CSI reporting configuration associated with the first CSI reporting configuration.

The association relationship between the first CSI reporting configuration and the second CSI reporting configuration may be notified to the terminal device in advance through a high layer signaling, that is, the association relationship between the first CSI reporting configuration and the second CSI reporting configuration is preconfigured through the high layer signaling.

In some embodiments, the association between the first CSI reporting configuration and the second CSI reporting configuration is indicated by the first CSI reporting configuration. For example, a configuration Identification (ID) indicating the associated second CSI reporting configuration in the first CSI reporting configuration.

In some embodiments, the CSI reporting configuration associated with the first CSI reporting configuration may be one or more, and in addition, the CSI reporting configuration associated with the first CSI reporting configuration may be indicated by information carried in the first CSI reporting configuration.

In some embodiments, in case the resource overlap type information indicates different resource overlap types, the interference measurement resources or interference measurement hypotheses used by the terminal device to make the CSI measurement are different.

It should be noted that, the interference measurement assumption used by the terminal device to perform CSI measurement may be, for example: one or more of the beam assumed by the interference measurement, the antenna panel (panel), and the precoder (precoder).

As embodiment 1, the resource overlap type information is used to indicate at least one of non-overlapping, partially overlapping, and fully overlapping.

In some implementations of embodiment 1, where the resource overlapping type information indicates that the resource overlapping type information does not overlap, S230 specifically includes:

and the terminal equipment performs CSI measurement according to the first CMR and the first IMR indicated in the first CSI reporting configuration.

That is, in case that the resource overlap type information indicates non-overlapping, the terminal device may perform CSI measurement and CSI reporting according to the first CMR and the first IMR indicated in the first CSI reporting configuration, without considering interference from another TRP.

In some implementations of embodiment 1, where the resource overlapping type information indicates a partial overlapping, S230 specifically includes:

The terminal equipment takes the second CMR as an interference measurement resource to carry out CSI measurement on the first sub-band, and does not take the second CMR as the interference measurement resource to carry out CSI measurement on the second sub-band;

the first sub-band is a reporting sub-band indicated in both the first CSI reporting configuration and the second CSI reporting configuration, the second sub-band is a reporting sub-band indicated in the first CSI reporting configuration but not indicated in the second CSI reporting configuration, the second CMR is a CMR indicated in the second CSI reporting configuration, and the second CSI reporting configuration is a CSI reporting configuration associated with the first CSI reporting configuration.

That is, in case the resource overlap type information indicates partial overlap, interference of another TRP is considered on the overlapping sub-bands in the associated two CSI reporting configurations, and interference of another TRP is not considered on the non-overlapping sub-bands.

For example, assume that in the first CSI reporting configuration, a first CMR is indicated as a channel measurement resource, a first IMR is indicated as an interference measurement resource, and the indicated reporting subband (Band) is { Band0, band1, band6, band7}; and in a second CSI reporting configuration related to the first CSI reporting configuration, a second CMR is indicated as a channel measurement resource, a second IMR is indicated as an interference measurement resource, and the indicated reporting sub-Band is { Band0, band1, band2, band3}. At this time, the first subband is a reporting subband indicated in both the first CSI reporting configuration and the second CSI reporting configuration, i.e., band0 and Band1; the second sub-Band is a reporting sub-Band indicated by the first CSI reporting configuration but not indicated in the second CSI reporting configuration, namely Band6 and Band7.

The terminal equipment takes the second CMR as interference measurement resources to carry out CSI measurement on the first sub-Band (namely Band0 and Band 1), namely the terminal equipment needs to carry out interference measurement on the second CMR and the first IMR, and carries out CSI calculation of the first CSI reporting configuration based on the measured interference. The terminal equipment does not use the second CMR as interference measurement resource on the second sub-Band (Band 6 and Band 7), i.e. the terminal equipment performs CSI measurement based on the first CMR and the first IMR only on the second sub-Band.

In some embodiments, in a case where the resource overlap type information indicates a partial overlap, the first CSI reporting configuration is not identical to the reporting subband indicated in the second CSI reporting configuration.

In some implementations of embodiment 1, if the first CSI reporting configuration is identical to the reporting sub-band indicated in the second CSI reporting configuration, the terminal device may perform CSI measurement on all reporting sub-bands with the second CMR indicated in the second CSI reporting configuration as an interference measurement resource.

In some implementations of embodiment 1, if the reporting subbands indicated in the first CSI reporting configuration and the second CSI reporting configuration are completely different, the terminal device may not perform CSI measurement on all the reporting subbands with the second CMR indicated in the second CSI reporting configuration as an interference measurement resource.

In some implementations of embodiment 1, where the resource overlap type information indicates complete overlap, S230 specifically includes:

the terminal equipment takes the second CMR as an interference measurement resource to carry out CSI measurement on all the subbands indicated in the first CSI reporting configuration;

the second CMR is a CMR indicated in a second CSI reporting configuration, where the second CSI reporting configuration is a CSI reporting configuration associated with the first CSI reporting configuration.

Specifically, for example, when the resource overlapping type information indicates complete overlapping, the terminal device performs interference measurement on all reporting subbands indicated by the first CSI reporting configuration, on both the second CMR indicated in the second CSI reporting configuration and the first IMR indicated in the first CSI reporting configuration, and performs CSI calculation of the first CSI reporting configuration based on the measured interference.

In some embodiments, in the case where the resource overlap type information indicates complete overlap, the first CSI reporting configuration is identical to the reporting subband indicated in the second CSI reporting configuration.

In some implementations of embodiment 1, in the case where the resource overlap type information indicates complete overlap, if the reporting subbands indicated in the first CSI reporting configuration and the second CSI reporting configuration are not identical, the terminal device only reports CSI on the overlapping subbands and does not report CSI on the non-overlapping subbands.

In embodiment 1, for example, as shown in fig. 5, in the case where the resource overlap type information indicates full overlap, channel measurement is performed on the first non-zero power CSI-RS (i.e., the CMR indicated in the first CSI reporting configuration), and interference measurement is performed on the first CSI-IM (i.e., the IMR indicated in the first CSI reporting configuration) and the second non-zero power CSI-RS (i.e., the CMR indicated in the second CSI reporting configuration). In case the resource overlap type information indicates a partial overlap, for the overlapping subbands, performing channel measurements on a first non-zero power CSI-RS (i.e., the CMR indicated in the first CSI reporting configuration) and performing interference measurements on a first CSI-IM (i.e., the IMR indicated in the first CSI reporting configuration) and a second non-zero power CSI-RS (i.e., the CMR indicated in the second CSI reporting configuration); for non-overlapping subbands, channel measurements are made on a first non-zero power CSI-RS (i.e., the CMR indicated in the first CSI reporting configuration) and interference measurements are made on a first CSI-IM (i.e., the IMR indicated in the first CSI reporting configuration). In case the resource overlap type information indicates no overlap, channel measurements are made on the first non-zero power CSI-RS (i.e. the CMR indicated in the first CSI reporting configuration) and interference measurements are made on the first CSI-IM (i.e. the IMR indicated in the first CSI reporting configuration).

In some implementations of embodiment 1, in a case where the resource overlap type information indicates a plurality of resource overlap types, the terminal device performs CSI measurements according to the plurality of resource overlap types, respectively, and the CSI measurements of the plurality of resource overlap types are based on the same CMR and/or different IMRs.

For example, when the resource overlap type information indicates non-overlap and full overlap, both resource overlap types perform channel measurement based on the same first CMR, but when interference measurement is performed, interference from another TRP (CSI reporting configuration) needs to be additionally considered in the case of full overlap.

In some implementations of embodiment 1, the terminal device reports CSI corresponding to the first CSI reporting configuration, where the CSI corresponding to the first CSI reporting configuration includes CSI corresponding to at least one resource overlapping type.

In some implementations of embodiment 1, when the resource overlapping type information indicates multiple resource overlapping types, the terminal device concatenates CSI corresponding to the multiple resource overlapping types according to a configuration order of the multiple resource overlapping types, and then feeds back the CSI in the same CSI report.

For example, when the resource overlapping type information indicates "complete overlapping" and "non-overlapping", the corresponding CSI is CSI0 and CSI1 respectively, and the terminal concatenates the two CSI in the order of { CSI0, CSI1} and reports the two CSI in the same CSI.

For the network side, after obtaining CSI corresponding to different resource overlapping types, the network device may use corresponding CSI for the scheduled PDSCH according to the current scheduling result (whether there is resource overlapping in PDSCH with different TRP), so as to obtain higher throughput.

In some implementations of embodiment 1, in a case where the resource overlap type information indicates a plurality of resource overlap types, the terminal device selects CSI corresponding to a part of resource overlap types from CSI corresponding to the plurality of resource overlap types to report CSI.

In some implementations, the terminal device may send first indication information to the network device, where the first indication information is used to indicate a resource overlapping type selected by the terminal device in the multiple resource overlapping types, or the first indication information is used to indicate an identifier of CSI corresponding to the resource overlapping type selected by the terminal device in the multiple resource overlapping types.

Note that, the first indication information may be reported together with the CSI corresponding to the first CSI reporting configuration, or may be reported separately, which is not limited in this application.

For example, assuming that the resource overlapping type information indicates "full overlapping", "partial overlapping" and "non-overlapping", the terminal device selects CSI corresponding to one resource overlapping type from CSI corresponding to each of the three resource overlapping types for reporting, and indicates the selected resource overlapping type with 2-bit information. Different states in the 2 bits correspond to different resource overlap types.

Specifically, the terminal device may recommend an optimal resource overlapping type according to the current channel state and report the corresponding CSI to the network device, so that the network device may use a corresponding scheduling policy to achieve the recommended overlapping state, and use the fed-back CSI to achieve a higher throughput.

In some implementations of embodiment 1, when the resource overlapping type information indicates a plurality of resource overlapping types and a part of CSI in CSI corresponding to the first CSI reporting configuration needs to be discarded, the terminal device performs discarding in sequence according to a configuration sequence of the plurality of resource overlapping types, or the terminal device performs discarding in a discarding sequence agreed with the network device.

For example, when the code rate of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH)/physical uplink control channel (Physical Uplink Control Channel, PUCCH) carrying CSI reporting corresponding to the first CSI reporting configuration exceeds a certain threshold, part of CSI needs to be discarded, so as to ensure that the discarded code rate does not exceed the threshold. Assuming that the resource overlapping type information indicates "partial overlapping" and "non-overlapping" (the configuration order of the partial overlapping is before), and the corresponding CSI is CSI0 and CSI1, when CSI is discarded, CSI corresponding to the reporting amount information with the configuration order after (i.e., CSI 1) may be discarded first, and CSI corresponding to the reporting amount information with the configuration order before (i.e., CSI 0) may be discarded again when needed, until the code rate meets the threshold.

In some implementations, the discard order agreed with the network device includes:

firstly discarding the CSI with the resource overlapping type being the CSI corresponding to the partial overlapping, then discarding the CSI with the resource overlapping type being the CSI corresponding to the complete overlapping, and then discarding the CSI with the resource overlapping type being the CSI corresponding to the non-overlapping.

In another implementation, the discard order agreed with the network device includes:

the method comprises the steps of discarding the CSI corresponding to the resource overlapping type completely overlapping, discarding the CSI corresponding to the resource overlapping type partially overlapping, and discarding the CSI corresponding to the resource overlapping type not overlapping. And so on.

As embodiment 2, the resource overlap type information is used to indicate at least one of non-overlapping, overlapping.

In some implementations of embodiment 2, where the resource overlapping type information indicates that the resource overlapping type information does not overlap, S230 specifically includes:

In some implementations of embodiment 2, in a case where the resource overlap type information indicates overlap, S230 specifically includes:

Specifically, for example, the terminal device performs interference measurement on all reporting subbands indicated by the first CSI reporting configuration, on both the second CMR indicated in the second CSI reporting configuration and the first IMR indicated in the first CSI reporting configuration, and performs CSI calculation of the first CSI reporting configuration based on the measured interference.

In some implementations, if the reporting subbands in the first CSI reporting configuration and the second CSI reporting configuration are not identical, the terminal device performs CSI measurement with the second CMR as an interference measurement resource on the first subband, and does not perform CSI measurement with the second CMR as an interference measurement resource on the second subband;

In some implementations, if the reporting subbands in the first CSI reporting configuration and the second CSI reporting configuration are the same, the terminal device performs CSI measurement on all the subbands with the second CMR indicated in the second CSI reporting configuration as an interference measurement resource, that is, only the first subband and no second subband at this time.

For example, assume that in the first CSI reporting configuration, a first CMR is indicated as a channel measurement resource, a first IMR is indicated as an interference measurement resource, and the indicated reporting subband is { Band0, band1, band2, band3}; and in a second CSI reporting configuration related to the first CSI reporting configuration, a second CMR is indicated as a channel measurement resource, a second IMR is indicated as an interference measurement resource, and the indicated reporting sub-Band is { Band2, band3, band4, band5}. At this time, the first sub-Band is Band2 and Band3, and the second sub-Band is Band0 and Band1. The terminal equipment performs interference measurement on the second CMR and the first IMR in the first sub-Band (i.e. Band2 and Band 3), and performs CSI calculation of the first CSI reporting configuration based on the measured interference. The terminal device does not use the second CMR as interference measurement resource on the second sub-bands (Band 0 and Band 1), i.e. the terminal performs CSI measurement based on the first CMR and the first IMR only. If the reporting subbands in the first and second CSI reporting configurations are { Band0, band1, band2, band3}, the terminal uses the second CMR as an interference measurement resource on all subbands.

In some implementations of embodiment 2, in a case where the resource overlap type information indicates a plurality of resource overlap types, the terminal device performs CSI measurements according to the plurality of resource overlap types, respectively, and the CSI measurements of the plurality of resource overlap types are based on the same CMR and/or different IMRs.

In some implementations of embodiment 2, the terminal device reports CSI corresponding to the first CSI reporting configuration, where the CSI corresponding to the first CSI reporting configuration includes CSI corresponding to at least one resource overlapping type.

In some implementations of embodiment 2, when the resource overlapping type information indicates multiple resource overlapping types, the terminal device concatenates CSI corresponding to the multiple resource overlapping types according to a configuration order of the multiple resource overlapping types, and then feeds back the CSI in the same CSI report.

For example, when the resource overlapping type information indicates "overlapping" and "non-overlapping", the corresponding CSI is CSI0 and CSI1 respectively, and then the terminal device concatenates the two CSI in the order { CSI1, CSI0} (the concatenation order is before after the configuration) and reports the two CSI in the same CSI.

In some implementations of embodiment 2, in a case where the resource overlap type information indicates a plurality of resource overlap types, the terminal device selects CSI corresponding to a part of resource overlap types from CSI corresponding to the plurality of resource overlap types to report CSI.

For example, when the resource overlapping type information indicates two resource overlapping types, the terminal device selects one CSI corresponding to one resource overlapping type from CSI corresponding to the two resource overlapping types for CSI reporting.

For example, the terminal device reports the indication information of the selected resource overlapping type, or the indication information of the CSI corresponding to the selected resource overlapping type. Specifically, 1-bit signaling may be used to indicate the selected resource overlap type or CSI corresponding to the selected resource overlap type.

In some implementations of embodiment 2, when the resource overlapping type information indicates a plurality of resource overlapping types and a part of CSI in CSI corresponding to the first CSI reporting configuration needs to be discarded, the terminal device performs discarding in sequence according to a configuration sequence of the plurality of resource overlapping types, or the terminal device performs discarding in a discarding sequence agreed with the network device.

For example, when the code rate of PUSCH/PUCCH carrying CSI reporting corresponding to the first CSI reporting configuration exceeds a certain threshold, part of CSI needs to be discarded, so as to ensure that the discarded code rate does not exceed the threshold. Assuming that the resource overlapping type information indicates "non-overlapping" and "overlapping" (the configuration order of non-overlapping is before), and the corresponding CSI is CSI0 and CSI1, when CSI is discarded, CSI corresponding to the reporting amount information with the configuration order before (i.e., CSI 0) may be discarded first, and CSI corresponding to the reporting amount information with the configuration order before (i.e., CSI 1) may be discarded again when needed, until the code rate meets the threshold.

and discarding the CSI corresponding to the overlapping type of the resource, and discarding the CSI corresponding to the non-overlapping type of the resource.

Therefore, in the embodiment of the application, the network device may instruct the terminal device to measure CSI under different PDSCH resource overlapping assumptions through the resource overlapping type information, so as to perform flexible scheduling of PDSCH under different resource overlapping conditions, and support multi-TRP simultaneous transmission based on multi-DCI. In addition, after obtaining CSI corresponding to different resource overlapping types, the network device may use corresponding CSI for the scheduled PDSCH according to the current scheduling result, so as to obtain higher throughput.
