Description

Technical Field

[0001] The present application belongs to the field of wireless communication technology, and specifically relates to a method and device for processing multiple TRP CSI reports. Background Art

[0002] 3GPP Rel-16 standardizes the multi-TRP / multi-panel scenario, which can increase transmission reliability and throughput performance. For example, a user equipment (UE, also known as a terminal) can receive the same data or different data from multiple TRPs.

[0003] Multiple TRPs can be divided into ideal backhaul and non-ideal backhaul.

[0004] When the backhaul line is not ideal, there is a large delay in the exchange of information between multiple TRPs, which is more suitable for independent scheduling. The positive confirmation / negative confirmation (ACK / NACK) and channel state information (CSI) report are fed back to each TRP respectively. It is usually applicable to multiple downlink control information (DCI) scheduling, that is, each TRP sends its own physical downlink control channel (PDCCH), each PDCCH schedules its own physical downlink shared channel (PDSCH), and multiple control resource sets (CORESET) configured for the UE are associated with different radio resource control (RRC) parameters CORESETPoolIndex, corresponding to different TRPs. Multiple PDSCHs scheduled by multiple DCIs may be non-overlapping, partially overlapping, or completely overlapping in time-frequency resources. On the overlapping time-frequency resources, each TRP is independently precoded according to its own channel, and the UE receives multi-layer data streams belonging to multiple PDSCHs in a non-coherent joint transmission (NCJT) manner.

[0005] In an ideal backhaul, multiple TRPs can exchange scheduling information and UE feedback information in real time. In addition to scheduling multiple PDSCHs through the above-mentioned multiple DCIs, a single DCI can also schedule PDSCHs, including the following transmission schemes:

[0006] Space Division Multiplex (SDM): Different data layers of the same transport block (TB) come from NCJT transmission of different TRPs;

[0007] Frequency-division multiplexing (FDM): Different frequency domain resources mapped to the same redundancy version (RV) of the same TB are sent from different TRPs, or different RVs of the same TB are mapped to different frequency domain resources and sent from different TRPs;

[0008] Time Division Multiplexing (TDM): Multiple repetitions of different RVs of the same TB come from different TRPs, such as repetitions within one time slot, or repetitions across multiple time slots.

[0009] At this time, ACK / NACK feedback and CSI report can be fed back to any TRP.

[0010] Rel-17 will make specific definitions for multi-TRP / multi-panel in terms of CSI report settings, report content, and CSI resource configuration, mainly including the following methods:

[0011] 1) Multiple CSI reporting settings are configured, and the resource setting of each CSI reporting setting corresponds to a TRP, that is, each CSI reporting setting corresponds to a CSI report of a TRP.

[0012] 2) The base station configures a CSI report setting, and defaults or indicates that a CSI report is jointly (commonly) calculated by multiple CSI resources.

[0013] The existing CSI reporting method and reporting format are not optimized according to the two possible CSI reporting settings, and there may be a situation where the feedback overhead is large or more important CSI information is discarded. Summary of the invention

[0072] In the following, in combination with the accompanying drawings, the method for obtaining the multi-TRP CSI report, the terminal and the network side equipment provided in the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0073] The following first briefly describes the communication vocabulary related to this application.

[0074] 1. Rel-16 CSI reporting mechanism based on Physical Uplink Shared Channel (PUSCH)

[0075] CSI is reported based on PUSCH and supports Type 1 wideband or subband CSI, and also supports Type 2 CSI.

[0076] For Type 1, Type 2 and enhanced Type 2 CSI based on PUSCH feedback, a CSI report consists of two parts (Part 1 and Part 2), where Part 1 has a fixed payload size and indicates the number of information bits of Part 2. Note that Part 1 must be transmitted in full before Part 2.

[0077] For Type 1 CSI feedback, Part 1 may include one or more of Rank Indication (RI), CSI-RS Resource Indication (CRI), and Channel Quality Indicator (CQI) of the first codeword, and Part 2 includes one or more of Precoding Matrix Indicator (PMI) and CQI of the second codeword;

[0078] For Type 2 CSI feedback, Part 1 includes one or more of RI, CQI, and non-zero wideband amplitude coefficient indication for each layer of Type 2 CSI, and Part 2 includes the PMI of Type 2 CSI;

[0079] For enhanced Type 2 CSI feedback, Part 1 includes RI, CQI, and an indication of the total number of non-zero amplitude coefficients of enhanced Type 2 CSI across layers, and Type 2 includes the PMI of enhanced Type 2 CSI;

[0080] When the CSI reported based on the PUSCH includes Part 1 and Part 2, the UE may delete part of the Part 2 CSI content. The deletion rules of Part 2 are shown in Table 1 and Table 2 in descending order of priority.

[0081] Among them, for enhanced Type2 CSI report, Group 0 includes indexes i1,1, i1,2 and i1,8,l (l=1,...,v); Group 1 includes indexes i1,5 (if reported), i1,6,l, high priority part i1,7,l, i2,3,l, high priority part i2,4,l, high priority part i2,5,l (l=1,...,v); Group 2 includes low priority part i1,7,l, low priority part i2,4,l, low priority part i2,5,l (l=1,...,v);

[0087] 2. Rel-16 CSI reporting mechanism based on the physical uplink control channel (PUCCH)

[0088] Periodic CSI reporting based on PUCCH format 2, 3, and 4 supports wideband Type 1 CSI;

[0089] Semi-persistent CSI reporting based on PUCCH supports Type 1 CSI;

[0090] Semi-persistent CSI reporting based on PUCCH format 2 supports wideband Type 1 CSI;

[0091] Semi-persistent CSI reporting based on PUCCH format 3 or 4 supports wideband and subband Type 1 CSI and Type 2 CSI Part 1;

[0092] For the case where subband Type 1 CSI is reported based on PUCCH format 3 or 4, the CSI load can be divided into two parts (Part 1 and Part 2), Part 1 includes part or all of RI, CRI, and CQI corresponding to the first codeword, and Part 2 includes PMI and CQI corresponding to the second codeword (when RI>4, there are two codewords);

[0093] If a CSI report contains two parts, the UE can delete the content of Part2CSI, and the priority order is consistent with the priority table based on PUSCH reporting.

[0094] 3. Possible Multi-TRP Report Format

[0095] Rel-17 supports CSI reporting consisting of two parts (Part 1 and Part 2) for CSI reporting settings related to NCJT measurement assumptions.

[0096] Part 1 includes the CSI-RS resource indicator (CRI), rank indication (RI), wideband (WB) channel quality indicator (CQI), subband (SB) CQI and zero padding (if necessary) of the first codeword (CW);

[0097] Part 2 includes information related to precoding matrix indicator (Precoding Matrix Indicator, PMI).

[0098] 4. Potential CSI reporting mechanism for multiple TRPs

[0099] Regarding the CSI reporting mechanism, the current recommendations (agreement) are as follows:

[0100] The following two methods are supported for a CSI report:

[0101] Mode 1: The UE can be configured to report X single TRP (STRP) measurement assumptions and 1 NCJT measurement assumption, where X = 0, 1, 2;

[0102] Method 2: Configure the UE to select and report an optimal measurement hypothesis from all STRP measurement hypotheses and NCJT measurement hypotheses.

[0103] 5. CSI Report Priority

[0104] The priority of CSI report is defined as: Pri(y,k,c,s)=2·N cells ·M s y+N cells ·M s ·k+M s ·c+s

[0105] Wherein, y=0 indicates aperiodic CSI report based on PUSCH report, y=1 indicates semi-persistent CSI report based on PUSCH report, y=2 indicates semi-persistent CSI report based on PUCCH report, y=3 indicates periodic CSI report based on PUCCH report, k=0 indicates report carrying L1-RSRP or L1-SINR, k=1 indicates report not carrying L1-RSRP or L1-SINR, c indicates serving cell index (cell index), N cellsIt represents the value of the higher-level parameter maxNrofServingCells, s represents reportConfigID, and Ms represents the value of the higher-level parameter maxNrofCSI-ReportConfigurations.

[0106] Note: The lower the Pri(y,k,c,s) value, the higher the priority.

[0107] To solve the problem that the existing CSI reporting method and reporting format are not optimized according to the two possible CSI reporting settings, there may be a large feedback overhead or discarding of more important CSI information, please refer to Figure 2 , an embodiment of the present application provides a method for processing a multi-TRP CSI report, including:

[0108] Step 21: The terminal generates and reports a multi-TRP CSI report according to one CSI reporting setting or according to multiple CSI reporting settings, wherein the multi-TRP CSI report is generated and / or reported in at least one of the following ways:

[0109] If the multi-TRP CSI report includes CSI of multiple measurement hypotheses, and at least two measurement hypotheses among the multiple measurement hypotheses can share a precoding matrix indication PMI, the multi-TRP CSI report only includes the PMI of one measurement hypothesis among the at least two measurement hypotheses;

[0110] If there are multiple CSI reports on the uplink resource used to carry the multi-TRP CSI report, reporting the multiple CSI reports according to the priorities of the multiple CSI reports;

[0111] If there are multiple CSI reports on the uplink resources used to carry the multi-TRP CSI reports, the multiple CSI reports are reported according to the discarding rule.

[0112] In an embodiment of the present application, the generation and / or reporting process when generating a multi-TRP CSI report according to two possible CSI report settings is optimized, which can reduce the CSI report overhead or increase the effectiveness of the CSI report. In an embodiment of the present application, if the multi-TRP CSI report contains CSI of multiple measurement assumptions, and at least two of the multiple measurement assumptions can share a precoding matrix indication PMI, the multi-TRP CSI report only includes the PMI of one of the at least two measurement assumptions, that is, the terminal only needs to report the PMI of one measurement assumption for the at least two measurement assumptions, which can reduce the CSI report overhead. At the same time, the network side applies the shared PMI to the at least two measurement assumptions for data transmission.

[0113] In an embodiment of the present application, optionally, the multi-TRP CSI report includes a first field, and the first field is used to indicate whether the at least two measurement assumptions share a PMI. Optionally, the first field is located in Part 1 of the CSI report. The first field may be a bitmap indication or a codepoint or a switch identifier (enable / disable / 0 / 1 / true / false). In an embodiment of the present application, optionally, if two or more PMIs corresponding to two or more CMRs of the multi-TRP CSI measurement assumption are shared with the PMI corresponding to the CMR of the single TRP measurement assumption, the first field is used to indicate the corresponding relationship of the PMI sharing. The corresponding relationship may be which PMI can be shared between the PMI corresponding to the CMR of the single TRP measurement assumption and the two or more PMIs corresponding to the two or more CMRs of the multi-TRP CSI measurement assumption. In which, if it is a two-level codebook case, the PMI may be composed of the first-level codebook, or the first-level codebook and the second-level codebook may be composed of the first-level codebook and the second-level codebook.

[0114] For example, the terminal indicates which MTRP measurement assumptions and STRP measurement assumptions share PMI among the N measurement assumptions (K1 single TRP (STRP) measurement assumptions, K2 multi-TRP (MTRP, including NCJT or JT) measurement assumptions, and K1+K2=N) in the CSI report through a bitmap with a length of K1*K2. Specifically assuming 2 STRP measurement assumptions and 2 MTRP measurement assumptions, according to the bitmap with a length of 4 (please refer to Table 3, in Table 3, 1 indicates shared PMI, and 0 indicates unshared PMI), it can be obtained that MTRP1 and (STRP1, STRP2) can share PMI, then the terminal only reports MTRP1 or (STRP1, STRP2) two PMIs, and MTRP2 two PMIs, and the network side applies these four PMIs to these four measurement assumptions for data transmission.

[0115] Table 3

[0116] STRP1 STRP2 MTRP1 1 1 MTRP2 0 0

[0117] For example, the terminal indicates through a bitmap of length K1*K2 which MTRP measurement hypotheses and STRP measurement hypotheses share PMI among the N measurement hypotheses (K1 single TRP (STRP) measurement hypotheses, K2 multi-TRP (MTRP, including NCJT or JT) measurement hypotheses, and K1+K2=N) in the CSI report. Specifically, 2 STRP measurement assumptions and 1 MTRP measurement assumption are assumed, where STRP1 corresponds to CMR1 and PMI1, STRP2 corresponds to CMR2 and PMI2, MTRP1 corresponds to CMR3, CMR4 and PMI3, PMI4, and CMR1 and CMR3 are in the same CMR group or have the same CMR ID or are the same resource, CMR2 and CMR4 are in the same CMR group or have the same CMR ID or are the same resource, then according to the bitmap of length 2 (please refer to Table 3, in Table 3, 1 indicates shared PMI, 0 indicates unshared PMI), it can be obtained that MTRP1 and (STRP1, STRP2) can share PMI, then the terminal only reports MTRP1 or (STRP1, STRP2) two PMIs, and the network side applies these two PMIs to the four measurement assumptions for data transmission. The same resource means that a certain STRP measurement hypothesis and a certain MTRP measurement hypothesis use the same CMR for measurement, that is, the network configures one or several CMR resources and indicates that this or these CMR resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

[0118] Table 3

[0119] STRP1 STRP2 MTRP1 1 1

[0120] For example: The terminal indicates through a 1-bit switch flag whether the three measurement hypotheses (two STRP measurement hypotheses and one MTRP measurement hypothesis) in the CSI report can share PMI. If it is indicated that MTRP1 and STRP1 can share PMI, the terminal only reports MTRP1 or (STRP1), and two PMIs of STRP2, and the network side applies these two PMIs to these three measurement hypotheses for data transmission. If it is indicated that PMI sharing is not possible, the terminal needs to report a total of four PMIs for the three measurement hypotheses.

[0121] For example: the terminal indicates through codepoint whether the three measurement hypotheses (2 STRP measurement hypotheses and 1 MTRP measurement hypothesis) in the CSI report can share PMI, where the STRP measurement hypothesis corresponds to one CMR and one PMI, and the MTRP measurement hypothesis corresponds to two CMRs and two PMIs. Since there are three measurement hypotheses in total, a 2-bit length sequence is required, with a total of four states. If the indicated codepoint is 10, it means that the first CMR of the MTRP measurement hypothesis and its corresponding first PMI can share PMI with the PMI of the first STRP measurement hypothesis. The terminal only reports the second PMI corresponding to the second CMR of the MTRP measurement hypothesis, the first PMI corresponding to the first CMR of the MTRP measurement hypothesis or the PMI of the first STRP measurement hypothesis, and the PMI of the second STRP measurement hypothesis, a total of three PMIs. At this time, it means that the first CMR of the MTRP measurement hypothesis and the CMR corresponding to the first STRP measurement hypothesis have the same ID or are in the same CMR group or are the same resource. The network side applies these three PMIs to these three measurement hypotheses for data transmission. If the indicated codepoint is 01, it means that the second CMR of the MTRP measurement assumption and its corresponding second PMI can share PMI with the PMI of the second STRP measurement assumption. The terminal only reports the first PMI corresponding to the first CMR of the MTRP measurement assumption, the second PMI corresponding to the second CMR of the MTRP measurement assumption or the PMI of the second STRP measurement assumption, and the PMI of the first STRP measurement assumption, a total of 3 PMIs. At this time, it means that the second CMR of the MTRP measurement assumption and the CMR corresponding to the second STRP measurement assumption have the same ID or are in the same CMR group or the same resource. The network side applies these 3 PMIs to these three measurement assumptions for data transmission. If the indicated codepoint is 00, PMI sharing is not possible, and the terminal needs to report a total of 4 PMIs for the three measurement assumptions.If the indication codepoint is 11, it means that the first CMR of the MTRP measurement assumption and its corresponding first PMI can share PMI with the PMI of the first STRP measurement assumption, and the second CMR of the MTRP measurement assumption and its corresponding second PMI can share PMI with the PMI of the second STRP measurement assumption. The terminal only reports the first PMI corresponding to the first CMR of the MTRP measurement assumption or the PMI of the first STRP measurement assumption, the second PMI corresponding to the second CMR of the MTRP measurement assumption or the PMI of the second STRP measurement assumption, a total of 2 PMIs. At this time, it means that the first CMR of the MTRP measurement assumption and the CMR corresponding to the first STRP measurement assumption have the same ID or are in the same CMR group or are the same resource, and the second CMR of the MTRP measurement assumption and the CMR corresponding to the second STRP measurement assumption have the same ID or are in the same CMR group or are the same resource, and the first CMR and the second CMR of the MTRP measurement assumption belong to different CMR groups. The network side applies these two PMIs to these three measurement assumptions for data transmission. The same resource means that a certain STRP measurement hypothesis and a certain MTRP measurement hypothesis use the same CMR for measurement, that is, the network configures one or several CMR resources and indicates that this or these CMR resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

[0122] For example: the terminal indicates through codepoint whether the two measurement hypotheses (one STRP measurement hypothesis and one MTRP measurement hypothesis) in the CSI report can share PMI, where the STRP measurement hypothesis corresponds to one CMR and one PMI, and the MTRP measurement hypothesis corresponds to two CMRs and two PMIs. Since there are two measurement hypotheses in total, a sequence of 1 bit length is required, with a total of 2 states. If the indicated codepoint is 1, it means that the target CMR of the MTRP measurement hypothesis and its corresponding target PMI can share PMI with the PMI of the STRP measurement hypothesis, where the target CMR and the CMR corresponding to the STRP measurement hypothesis belong to the same CMR group or have the same CMR ID or are the same resource. The terminal only reports the PMI corresponding to the CMR other than the target CMR of the MTRP measurement hypothesis, the target PMI corresponding to the target CMR of the MTRP measurement hypothesis or the PMI of the STRP measurement hypothesis, a total of 2 PMIs. The network side applies these 2 PMIs to the two measurement hypotheses for data transmission. If the indicated codepoint is 0, PMI sharing is not possible, and the terminal needs to report a total of 3 PMIs of the two measurement hypotheses. The same resource means that a certain STRP measurement hypothesis and a certain MTRP measurement hypothesis use the same CMR for measurement, that is, the network configures one or several CMR resources and indicates that this or these CMR resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

[0123] For example: the terminal indicates through codepoint whether the two measurement hypotheses (1 STRP measurement hypothesis and 1 MTRP measurement hypothesis) in the CSI report can share PMI, where the STRP measurement hypothesis corresponds to one CMR and one PMI, and the MTRP measurement hypothesis corresponds to two CMRs (first CMR and second CMR) and two PMIs. There may be three situations, so a 2-bit length is required. That is, if the indicated codepoint is 01, it means that the first CMR of the MTRP measurement hypothesis and its corresponding PMI can share PMI with the PMI of the STRP measurement hypothesis. The terminal only reports the PMI corresponding to the second CMR of the MTRP measurement hypothesis, the PMI corresponding to the first CMR of the MTRP measurement hypothesis, or the PMI of the STRP measurement hypothesis, a total of 2 PMIs. The network side applies these two PMIs to these two measurement hypotheses for data transmission. If the indicated codepoint is 10, it means that the second CMR of the MTRP measurement hypothesis and its corresponding PMI can share PMI with the PMI of the STRP measurement hypothesis. The terminal only reports the PMI corresponding to the first CMR of the MTRP measurement hypothesis, the PMI corresponding to the second CMR of the MTRP measurement hypothesis, or the PMI of the STRP measurement hypothesis, a total of 2 PMIs. The network side applies these 2 PMIs to these two measurement hypotheses for data transmission. If the indicated codepoint is 00, PMI sharing is not possible, and the terminal needs to report a total of 3 PMIs for the two measurement hypotheses. The same resource refers to a STRP measurement hypothesis and a MTRP measurement hypothesis using the same CMR for measurement, that is, the network configures one or several CMR resources and indicates that this or these CMR resources can be used for both STRP measurement hypotheses and MTRP measurement hypotheses.

[0124] In an embodiment of the present application, if the multi-TRP CSI report includes CSI of multiple measurement hypotheses, and at least two measurement hypotheses among the multiple measurement hypotheses can share a precoding matrix indication RI, the multi-TRP CSI report only includes the RI of one measurement hypothesis among the at least two measurement hypotheses, that is, the terminal only needs to report the RI of one measurement hypothesis for the at least two measurement hypotheses, which can reduce the CSI reporting overhead. At the same time, the network side applies the shared RI to the at least two measurement hypotheses for data transmission.

[0125] In an embodiment of the present application, optionally, the multi-TRP CSI report includes a first field, and the first field is used to indicate whether the at least two measurement assumptions share RI. Optionally, the first field is located in Part 1 of the CSI report. The first field can be a bitmap indication or a codepoint or a switch identifier (enable / disable / 0 / 1 / true / false).

[0126] In an embodiment of the present application, optionally, if two or more RIs corresponding to two or more CMRs assumed by multi-TRP CSI measurement are shared with the RI corresponding to the CMR assumed by a single TRP measurement, the first field is used to indicate the corresponding relationship of RI sharing. The corresponding relationship may be which RI can be shared between the RI corresponding to the CMR assumed by a single TRP measurement and the two or more RIs corresponding to the two or more CMRs assumed by the multi-TRP CSI measurement.

[0127] For example, the terminal indicates which MTRP measurement assumptions and STRP measurement assumptions share RI among the N measurement assumptions (K1 single TRP (STRP) measurement assumptions, K2 multi-TRP (MTRP, including NCJT or JT) measurement assumptions, and K1+K2=N) in the CSI report through a bitmap with a length of K1*K2. Specifically assuming 2 STRP measurement assumptions and 2 MTRP measurement assumptions, according to the bitmap with a length of 4 (please refer to Table 3, in Table 3, 1 indicates shared RI, and 0 indicates unshared RI), it can be obtained that MTRP1 and (STRP1, STRP2) can share RI, then the terminal only reports MTRP1 or (STRP1, STRP2) two RIs, and MTRP2 two RIs, and the network side applies these four RIs to these four measurement assumptions for data transmission.

[0128] Table 3

[0129] STRP1 STRP2 MTRP1 1 1 MTRP2 0 0

[0130] For example, the terminal indicates through a bitmap of length K1*K2 which MTRP measurement hypotheses and STRP measurement hypotheses share RI among the N measurement hypotheses (K1 single TRP (STRP) measurement hypotheses, K2 multi-TRP (MTRP, including NCJT or JT) measurement hypotheses, and K1+K2=N) in the CSI report. Specifically, assume that there are 2 STRP measurement assumptions and 1 MTRP measurement assumption, where STRP1 corresponds to CMR1 and RI1, STRP2 corresponds to CMR2 and RI2, MTRP1 corresponds to CMR3, CMR4 and RI3, RI4, and CMR1 and CMR3 are in the same CMR group or have the same CMR ID or are the same resource, and CMR2 and CMR4 are in the same CMR group or have the same CMR ID or are the same resource. Then, according to the bitmap of length 2 (please refer to Table 3, in which 1 indicates shared RI and 0 indicates unshared RI), it can be obtained that MTRP1 and (STRP1, STRP2) can share RI, then the terminal only reports MTRP1 or (STRP1, STRP2) two RIs, and the network side applies these two RIs to the four measurement assumptions for data transmission. The same resource means that a certain STRP measurement assumption and a certain MTRP measurement assumption use the same CMR for measurement, that is, the network configures one or several CMR resources and indicates that this or these CMR resources can be used for both STRP measurement assumptions and MTRP measurement assumptions.

[0131] Table 3

[0132] STRP1 STRP2 MTRP1 1 1

[0133] For example: The terminal indicates through a 1-bit switch flag whether the three measurement hypotheses (two STRP measurement hypotheses and one MTRP measurement hypothesis) in the CSI report can share RI. If it is indicated that MTRP1 and STRP1 can share RI, the terminal only reports 2 RIs of MTRP1 or (STRP1) and STRP2, and the network side applies these 2 RIs to these three measurement hypotheses for data transmission. If it is indicated that RI sharing is not possible, the terminal needs to report a total of 4 RIs for the three measurement hypotheses.

[0134] For example: the terminal indicates through codepoint whether the three measurement hypotheses (2 STRP measurement hypotheses and 1 MTRP measurement hypothesis) in the CSI report can share RI, where the STRP measurement hypothesis corresponds to one CMR and one RI, and the MTRP measurement hypothesis corresponds to two CMRs and two RIs. Since there are three measurement hypotheses in total, a 2-bit sequence is required. If the indicated codepoint is 10, it means that the first CMR of the MTRP measurement hypothesis and its corresponding first RI can share RI with the RI of the first STRP measurement hypothesis. The terminal only reports the second RI corresponding to the second CMR of the MTRP measurement hypothesis, the first RI corresponding to the first CMR of the MTRP measurement hypothesis or the RI of the first STRP measurement hypothesis, and the RI of the second STRP measurement hypothesis, a total of three RIs. At this time, it means that the first CMR of the MTRP measurement hypothesis and the CMR corresponding to the first STRP measurement hypothesis have the same ID or are in the same CMR group or are the same resource. The network side applies these three RIs to these three measurement hypotheses for data transmission. If the indicated codepoint is 01, it means that the second CMR of the MTRP measurement hypothesis and its corresponding second RI can share RI with the RI of the second STRP measurement hypothesis. The terminal only reports the first RI corresponding to the first CMR of the MTRP measurement hypothesis, the second RI corresponding to the second CMR of the MTRP measurement hypothesis or the RI of the second STRP measurement hypothesis, and the RI of the first STRP measurement hypothesis, a total of 3 RIs. At this time, it means that the second CMR of the MTRP measurement hypothesis and the CMR corresponding to the second STRP measurement hypothesis have the same ID or are in the same CMR group or are the same resource. The network side applies these 3 RIs to these three measurement hypotheses for data transmission. If the indicated codepoint is 00, RI sharing is not possible, and the terminal needs to report a total of 4 RIs for the three measurement hypotheses.If the indication codepoint is 11, it means that the first CMR of the MTRP measurement assumption and its corresponding first RI can share RI with the RI of the first STRP measurement assumption, and the second CMR of the MTRP measurement assumption and its corresponding second RI can share RI with the RI of the second STRP measurement assumption. The terminal only reports the first RI corresponding to the first CMR of the MTRP measurement assumption or the RI of the first STRP measurement assumption, the second RI corresponding to the second CMR of the MTRP measurement assumption or the RI of the second STRP measurement assumption, a total of 2 RIs. At this time, it means that the first CMR of the MTRP measurement assumption and the CMR corresponding to the first STRP measurement assumption have the same ID or are in the same CMR group or are the same resource, and the second CMR of the MTRP measurement assumption and the CMR corresponding to the second STRP measurement assumption have the same ID or are in the same CMR group or are the same resource, and the first CMR and the second CMR of the MTRP measurement assumption belong to different CMR groups. The network side applies these two RIs to these three measurement assumptions for data transmission. The same resource means that a certain STRP measurement hypothesis and a certain MTRP measurement hypothesis use the same CMR for measurement, that is, the network configures one or several CMR resources and indicates that this or these CMR resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

[0135] For example: the terminal indicates through codepoint whether the two measurement hypotheses (one STRP measurement hypothesis and one MTRP measurement hypothesis) in the CSI report can share RI, where the STRP measurement hypothesis corresponds to one CMR and one RI, and the MTRP measurement hypothesis corresponds to two CMRs and two RIs. Since there are two measurement hypotheses in total, a sequence of 1 bit length is required. If the indicated codepoint is 1, it means that the target CMR of the MTRP measurement hypothesis and its corresponding target RI can share RI with the RI of the STRP measurement hypothesis, where the target CMR and the CMR corresponding to the STRP measurement hypothesis belong to the same CMR group or have the same CMRID or are the same resource. The terminal only reports the RI corresponding to the CMR other than the target CMR of the MTRP measurement hypothesis, the target RI corresponding to the target CMR of the MTRP measurement hypothesis or the RI of the STRP measurement hypothesis, a total of 2 RIs. The network side applies these 2 RIs to the two measurement hypotheses for data transmission. If the indicated codepoint is 0, RI sharing is not possible, and the terminal needs to report a total of 3 RIs for the two measurement hypotheses. The same resource means that a certain STRP measurement hypothesis and a certain MTRP measurement hypothesis use the same CMR for measurement, that is, the network configures one or several CMR resources and indicates that this or these CMR resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

[0136] In the embodiment of the present application, optionally, the at least two measurement assumptions have the same RI.

[0140] In an embodiment of the present application, optionally, if there are multiple CSI reports on the uplink resources (PUCCH or PUSCH) used to carry the multiple TRP CSI reports, the multiple CSI reports are reported in sequence according to the priorities of the multiple CSI reports, and the number of reported CSI reports is determined by the uplink resources used to carry the multiple TRP CSI reports. If the uplink resources can carry the reports of the multiple CSI reports at the same time, the multiple CSI reports can all be reported. If the uplink resources cannot carry the multiple CSI reports at the same time, the reported CSI reports are selected in order of priority from high to low. At this time, the number of reported CSI reports can be one or more.

[0141] In the embodiment of the present application, the priorities of multiple CSI reports are defined to ensure that the CSI report with the highest priority is reported on the priority uplink resource, thereby improving the effectiveness of the CSI report.

[0168] 9) When the reporting time domain types of the multiple CSI reports are the same, the priority of the single TRP CSI report is higher than that of the multi-TRP CSI report or the priority of the multi-TRP CSI report is higher than that of the single TRP CSI report, wherein the multi-TRP CSI report includes at least one of the following: a multi-TRP CSI report carrying the measurement results of a single TRP measurement hypothesis or the measurement results of multiple TRP measurement hypotheses, a multi-TRP CSI report carrying the measurement results of 0 single TRP measurement hypotheses and 1 multi-TRP measurement hypothesis, a multi-TRP CSI report carrying the measurement results of 1 single TRP measurement hypothesis and 1 multi-TRP measurement hypothesis, and a multi-TRP CSI report carrying the measurement results of 2 single TRP measurement hypotheses and 1 multi-TRP measurement hypothesis.

[0177] In the present application, Pri iCSI The lower the (y, k, c, s, i) value, the higher the priority.

[0178] In an embodiment of the present application, optionally, if there are multiple CSI reports on the uplink resource used to carry the multiple TRP CSI reports, and the uplink resource cannot carry the reporting of the multiple CSI reports at the same time, a discard rule is triggered, and the multiple CSI reports are reported according to the discard rule. If there are multiple CSI reports on the uplink resource used to carry the multiple TRP CSI reports, and the uplink resource can carry the reporting of the multiple CSI reports at the same time, the discard rule is not triggered.

[0179] In the embodiment of the present application, by defining a discarding rule for CSI information carried in the MTRP CSI report, it is ensured that CSI information with high validity is reported on limited uplink resources, thereby improving the validity of the MTRP CSI report.

[0180] In the embodiment of the present application, optionally, the discarding rule includes:

[0181] If the reporting resources cannot carry the reporting of the multiple CSI reports at the same time, the CSI information of the target CSI report with the lowest current priority among the multiple CSI reports is discarded according to one of the following, until the reporting resources can meet the reporting of the CSI report:

[0183] discarding CSI information of a target measurement hypothesis in the target CSI report according to the CQI;

[0184] The CSI information of the target measurement hypothesis in the target CSI report is discarded according to the RI and the CQI.

[0185] In this embodiment of the present application, the target measurement hypothesis may be one or more measurement hypotheses in the target CSI report.

[0186] For example, there are three CSI reports on the reporting resource, CSI report 1, CSI report 2 and CSI report 3. The transmission priority of CSI report 1 is higher than that of CSI report 2, and the transmission priority of CSI report 2 is higher than that of CSI report 3. If the reporting resource cannot carry the reporting of the three CSI reports at the same time, the CSI information of CSI report 3 with the lowest current priority is discarded first, and the CSI information of the target measurement hypothesis in CSI report 3 can be discarded according to RI, CQI, or RI and CAI until the reporting resource can carry the reporting of the CSI report. If the CSI information of all measurement hypotheses in CSI report 3 is discarded, and the reporting resource still cannot carry the reporting of the CSI report at the same time, the CSI information of CSI report 2 with the lowest current priority is discarded, and so on, until the reporting resource can carry the reporting of the CSI report.

[0187] In the embodiment of the present application, the discarded CSI information includes at least one of the following: PMI, LI, second codeword CQI, etc.

[0188] In the embodiment of the present application, optionally, discarding the CSI information of the target measurement hypothesis in the target CSI report according to the RI includes: discarding the CSI information of the target measurement hypothesis in the target CSI report in order of RI from low to high. That is, first discard the CSI information of the measurement hypothesis with the lowest RI in the target CSI report, and if the reporting resources still cannot meet the reporting of the CSI report, continue to discard the CSI information of the measurement hypothesis with the lowest current RI in the target CSI report.

[0189] In the embodiment of the present application, optionally, discarding the CSI information of the target measurement hypothesis in the target CSI report according to the CQI includes: discarding the CSI information of the target measurement hypothesis in the target CSI report in order of CQI from low to high. That is, first discard the CSI information of the measurement hypothesis with the lowest CQI in the target CSI report, and if the reporting resources still cannot meet the reporting of the CSI report, continue to discard the CSI information of the measurement hypothesis with the lowest current CQI in the target CSI report.

[0190] In the embodiment of the present application, optionally, discarding the CSI information of the target measurement hypothesis in the target CSI report according to the RI and the CQI includes:

[0191] Calculate a first value for each measurement hypothesis in the target CSI report according to the RI and the CQI;

[0192] The CSI information of the target measurement hypothesis in the target CSI report is discarded according to the order of the first values ​​from low to high.

[0193] In the embodiment of the present application, optionally, the first value is the amount of transmittable information calculated based on RI and CQI.

[0194] In some embodiments of the present application, further optionally, the discard rule also includes:

[0195] The CSI information of the target measurement hypothesis in the target CSI report is discarded in the following order:

[0196] Odd subband CSI information of the target measurement hypothesis;

[0197] Even subband CSI information of the target measurement hypothesis;

[0198] The target measurement assumes wideband CSI information.

[0199] That is, the odd subband CSI information of the target measurement assumption is discarded first. If the uplink resources cannot meet the reporting requirements of the CSI report, the even subband CSI information of the target measurement assumption is discarded. If the uplink resources still cannot meet the reporting requirements of the CSI report, the wideband CSI information of the target measurement assumption is discarded.

[0200] The above-mentioned method of discarding in order of odd subband CSI information, even subband CSI information and wideband CSI information is applicable to the three scenarios of discarding according to RI, discarding according to CQI, and / or discarding the CSI information of the target measurement hypothesis in the target CSI report according to RI and CQI.

[0201] For example: there are 3 CSI reports on the reporting resource, CSI report 1, CSI report 2 and CSI report 3. The transmission priority of CSI report 1 is higher than that of CSI report 2, and the transmission priority of CSI report 2 is higher than that of CSI report 3. If the reporting resource cannot carry the reporting of the 3 CSI reports at the same time, the CSI information of CSI report 3 with the lowest current priority is discarded first, and the CSI information of the target measurement assumption in CSI report 3 can be discarded according to RI, CQI, or RI and CAI. When discarding the CSI information of the target measurement assumption in CSI report 3, the odd subband CSI information of the target measurement assumption can be discarded first, and then the even subband CSI information of the target measurement assumption can be discarded, and finally the wideband CSI information of the target measurement assumption can be discarded in this order until the reporting resource can carry the reporting of the CSI report. If the CSI information of all measurement assumptions in CSI report 3 is discarded, and the reporting resources still cannot carry the CSI report at the same time, the CSI information of CSI report 2 with the lowest current priority is discarded (see CSI report 3 for the discarding method), and so on, until the reporting resources can carry the CSI report.

[0202] In some embodiments of the present application, further optionally, the discard rule also includes:

[0203] The CSI information of the target measurement hypothesis in the target CSI report is discarded in the following order:

[0204] Odd-numbered subband CSI information of the target measurement hypothesis;

[0205] The target measurement assumes even subband CSI information.

[0206] That is, the odd subband CSI information of the target measurement assumption is discarded first, and if the uplink resources cannot meet the reporting requirements of the CSI report, the even subband CSI information of the target measurement assumption is discarded. Further optionally, if the subband CSI information of all measurement assumptions in the target CSI report is discarded and the reporting resources are still unable to carry the reporting of the CSI report at the same time, the wideband CSI information of all measurement assumptions in the target CSI report is discarded.

[0207] In this embodiment, the three scenarios of discarding the CSI information of the target measurement hypothesis in the target CSI report according to RI, discarding according to CQI, and / or discarding according to RI and CQI are also described above.

[0208] For example: there are three CSI reports on the reporting resource, CSI report 1, CSI report 2 and CSI report 3, the transmission priority of CSI report 1 is higher than that of CSI report 2, and the transmission priority of CSI report 2 is higher than that of CSI report 3. If the reporting resource cannot carry the reporting of the three CSI reports at the same time, the CSI information of CSI report 3 with the lowest current priority is discarded first, and the CSI information of the target measurement hypothesis in CSI report 3 can be discarded according to RI, CQI, or RI and CAI. When discarding the CSI information of the target measurement hypothesis in CSI report 3, the odd subband CSI information of the target measurement hypothesis can be discarded first, and then the even subband CSI information of the target measurement hypothesis can be discarded until the reporting resource can carry the reporting of the CSI report. If the subband CSI information of all measurement assumptions in CSI report 3 is discarded, and the reporting resource still cannot carry the reporting of the CSI report at the same time, the wideband CSI information of all measurement assumptions in CSI report 3 is discarded. If the reporting resources still cannot carry the CSI report at the same time, the CSI information of CSI report 2 with the lowest current priority is discarded (see CSI report 3 for the discarding method), and so on, until the reporting resources can carry the CSI report.

[0209] In some embodiments of the present application, further optionally, the discard rule also includes:

[0210] The CSI information of the target measurement hypothesis in the target CSI report is discarded in the following order:

[0211] Odd subband CSI information of the target measurement hypothesis;

[0212] The target measurement assumes even subband CSI information.

[0213] That is, the odd subband CSI information of the target measurement hypothesis is discarded first, and if the uplink resources cannot meet the reporting requirements of the CSI report, the even subband CSI information of the target measurement hypothesis is discarded. Further optionally, if the subband CSI information of all measurement assumptions in all CSI reports is discarded and the reporting resources still cannot simultaneously carry the reporting of the CSI report, the wideband CSI information of all measurement assumptions in all CSI reports is discarded.

[0214] In this embodiment, the three scenarios of discarding the CSI information of the target measurement hypothesis in the target CSI report according to RI, discarding according to CQI, and / or discarding according to RI and CQI are also described above.

[0215] For example: there are two CSI reports on the reporting resource, CSI report 1 and CSI report 2, and the transmission priority of CSI report 1 is higher than that of CSI report 2. If the reporting resource cannot carry the reporting of the two CSI reports at the same time, the CSI information of CSI report 2 with the lowest current priority is discarded first, and the CSI information of the target measurement hypothesis in CSI report 2 can be discarded according to RI, CQI, or RI and CAI. When discarding the CSI information of the target measurement hypothesis in CSI report 2, the odd subband CSI information of the target measurement hypothesis can be discarded first, and then the even subband CSI information of the target measurement hypothesis can be discarded until the reporting resource can carry the reporting of the CSI report. If the subband CSI information of all measurement assumptions in CSI report 2 is discarded, and the reporting resource still cannot carry the reporting of the CSI report at the same time, the subband CSI information of all measurement assumptions in CSI report 1 is discarded. If the reporting resource still cannot carry the reporting of the CSI report at the same time, the wideband CSI information of all measurement assumptions in CSI report 1 and CSI report 2 is discarded.

[0216] In some embodiments of the present application, optionally, the discarding rule includes:

[0217] If the reporting resource cannot carry the reporting of the multiple CSI reports at the same time, discard the subband CSI information in the CSI report in order of priority of the multiple CSI reports from low to high, and the subband CSI information of each CSI report includes odd subband CSI information and even subband CSI information, wherein when discarding the subband CSI information in the CSI report, discard it in the order of odd subband CSI information of all measurement assumptions and even subband CSI information of all measurement assumptions until the reporting resource can meet the reporting of the CSI report;

[0218] If the reporting resources are still unable to simultaneously carry the reporting of the CSI report after all the subband CSI information of the CSI report is discarded, all the wideband CSI information in the multiple CSI reports are discarded, wherein each wideband CSI information corresponds to one CSI report.

[0219] For example: there are two CSI reports on the reporting resource, CSI report 1 and CSI report 2, and the transmission priority of CSI report 1 is higher than that of CSI report 2. If the reporting resource cannot carry the reporting of the two CSI reports at the same time, the subband CSI information of CSI report 2 with the lowest current priority is first discarded, wherein when discarding the subband CSI information in CSI report 2, the odd subband CSI information of all measurement assumptions can be discarded first, and then the even subband CSI information of all measurement assumptions can be discarded until the reporting resource can carry the reporting of the CSI report. If the subband CSI information of all measurement assumptions in CSI report 2 is discarded, and the reporting resource still cannot carry the reporting of the CSI report at the same time, the subband CSI information of all measurement assumptions in CSI report 1 is discarded. If the reporting resource still cannot carry the reporting of the CSI report at the same time, the wideband CSI information of all measurement assumptions in CSI report 1 and CSI report 2 is discarded.

[0220] In some embodiments of the present application, optionally, the discarding rule includes:

[0221] If the reporting resource cannot carry the reporting of the multiple CSI reports at the same time, discard the CSI information in the CSI report in order of priority of the multiple CSI reports from low to high;

[0222] The CSI information of each CSI report includes wideband CSI information, odd subband CSI information and even subband CSI information. When discarding the CSI information in the CSI report, the information is discarded in the order of odd subband CSI information of all measurement assumptions, even subband CSI information of all measurement assumptions, and wideband CSI information of all measurement assumptions until the reporting resources can meet the reporting of the CSI report.

[0223] For example: there are 2 CSI reports on the reporting resource, CSI report 1 and CSI report 2, and the transmission priority of CSI report 1 is higher than that of CSI report 2. If the reporting resource cannot carry the reporting of the two CSI reports at the same time, the CSI information of CSI report 2 with the lowest current priority is discarded first. When discarding the CSI information in CSI report 2, the odd subband CSI information of all measurement assumptions can be discarded first, then the even subband CSI information of all measurement assumptions can be discarded, and finally the wideband CSI information of all measurement assumptions can be discarded until the reporting resource can carry the reporting of the CSI report. If the CSI information of all measurement assumptions in CSI report 2 is discarded, and the reporting resource still cannot carry the reporting of the CSI report at the same time, the CSI information in CSI report 1 is discarded (see CSI report 2 for the discarding method).

[0224] In the above embodiment, relatively important CSI information is retained to improve the effectiveness of the CSI report.

[0225] Please refer to Figure 3 The embodiment of the present application also provides a method for processing a multi-TRP CSI report, including:

[0238] When C=2, the number of CPUs is xN+S, where x is a number less than or equal to 4, which can be an integer or a decimal.

[0239] When C>2, the number of CPUs is 2*C*N+S, or xN+S, where x is a number less than or equal to 2*C, and this number can be an integer or a decimal;

[0243] When P>2, the number of CPUs is 2*P*N+S, or xN+S, where x is a number less than or equal to 2*P, and this number can be an integer or a decimal.

[0244] Example 3: The number of allocated CPUs is related to the number of CMRs used for the STRP measurement hypothesis (S) and the number of CMR pairs used for the MTRP measurement hypothesis (N);

[0246] When the UE is scheduled by multiple-DCI, the number of CPUs is xN+S, where x is a number less than or equal to 4, and can be an integer or a decimal.
