Description

Method and device for processing multi-TRP CSI report

Technical Field

The application belongs to the technical field of wireless communication, and particularly relates to a method and a device for processing a multi-TRP CSI report.

Background

The 3GPP Rel-16 standardizes a multiple-transmit-receive point/multiple-antenna panel (multi-TRP/multi-panel) scenario, which may increase reliability and throughput performance of transmission, e.g., a User Equipment (UE, which may also be referred to as a terminal) may receive the same data or different data from multiple TRPs.

The multi-TRP can be divided into ideal backhaul (ideal backhaul) and non-ideal backhaul (non-ideal backhaul).

When the non-ideal backhaul is in a non-ideal backhaul, the interaction Information among multiple TRPs has larger time delay, is relatively suitable for independent scheduling, and is fed back to each TRP respectively by a positive acknowledgement/negative acknowledgement (ACK/NACK) report and a channel state Information (CHANNEL STATE Information (CSI) report. It is generally applicable to multiple downlink control information (Downlink Control Information, DCI) scheduling, i.e. each TRP transmits a respective physical downlink control channel (Physical Downlink Control Channel, PDCCH), each PDCCH schedules a respective physical downlink shared channel (Physical Downlink SHARED CHANNEL, PDSCH), multiple control resource sets (control resource set, CORESET) configured for a UE are associated to different radio resource control (Radio Resource Control, RRC) parameter control resource set pool indices (CORESETPoolIndex) corresponding to different TRPs. The multiple PDSCH scheduled by multiple DCI may be non-overlapping, partially overlapping, fully overlapping on time-frequency resources. On the overlapping time-frequency resources, each TRP is independently precoded according to a respective channel, and the UE receives the multi-layer data streams belonging to multiple PDSCH in a Non-coherent joint transmission (Non-Coherent Joint Transmission, NCJT) manner.

When the backhaul is ideal, the scheduling information and the feedback information of the UE can be interacted in real time between the multiple TRPs, and besides the multiple PDSCH can be scheduled by the multiple DCI, the PDSCH can be scheduled by the single DCI, which comprises the following transmission schemes:

Space division multiplexing (Space Division Multiplex, SDM) NCJT transmissions from different TRPs for different data layers of the same Transport Block (TB);

frequency Division Multiplexing (FDM) in which different Frequency domain resources mapped by the same redundancy version (redundancy version, RV) of the same TB are mapped from different TRPs or different RVs of the same TB are mapped to different Frequency domain resources and are derived from different TRPs;

Time division multiplexing (Time Division Multiplexing, TDM) multiple repetitions of different RVs of the same TB come from different TRPs, e.g. repetitions within one time slot, or repetitions of multiple time slots.

At this time, the ACK/NACK feedback and CSI report may be fed back to any one TRP.

Rel-17 will specifically define the multi-TRP/multi-panel from CSI report setting, report content, and CSI resource allocation, and mainly includes the following methods:

1) A plurality of CSI report settings (Reporting setting) are configured, the resource setting (resource setting) of each CSI report setting corresponding to one TRP, i.e., the CSI report of each CSI report setting corresponding to one TRP.

2) The base station configures a CSI report setting that defaults or indicates that a CSI report is jointly (co) calculated from multiple CSI resources.

The existing CSI reporting method and reporting format are not optimized according to two possible CSI reporting settings, and there may be a case that feedback overhead is large or more important CSI information is discarded.

The communication vocabulary related to the present application will be briefly described below.

1. CSI reporting mechanism of Rel-16 based on Physical Uplink SHARED CHANNEL, PUSCH

CSI is based on PUSCH reporting, supporting Type1 (Type 1) wideband or subband CSI, while also supporting Type2 (Type 2) CSI.

For Type1, type2 and enhanced Type2 CSI are based on PUSCH feedback, one CSI report (report) consists of two parts (Part 1 and Part 2), where Part1 has a fixed payload size, while indicating the number of information bits (bits) of Part2, note that Part1 is to be transmitted in its entirety before Part 2.

For Type1 CSI feedback, part1 may include one or more of a Rank Indication (RI), a CSI-RS resource Indication (CRI), a channel quality Indication (Channel Quality Indicator, CQI) of a first codeword, part2 contains one or more of a precoding matrix Indication (Precoding Matrix Indicator, PMI) and a CQI of a second codeword;

For Type2 CSI feedback, part1 includes one or more of RI, CQI, and Type2 CSI per layer non-zero wideband amplitude coefficient indication, part2 includes PMI for Type2 CSI;

for enhanced Type2 CSI feedback, part1 includes an indication of the total number of RI, CQI, enhanced Type2 CSI cross-layer non-zero amplitude coefficients, type2 contains PMI of enhanced Type2 CSI;

when the PUSCH report-based CSI contains Part1 and Part2, the UE may delete Part of the Part2 CSI content, and the deletion rule of Part2 is shown in the order of priority from high to low in table 1 and table 2.

Wherein, for enhanced Type2 CSI reporting, group 0 includes indexes i1, i1,2, and i1,8,l (l=1,., v); group1 contains indices i1,5 (if reported), i1,6,l, high priority parts i1,7, l, i2,3, l, high priority parts i2,4, l, high priority parts i2,5,l (l=1., v); group2 includes low priority parts i1,7,l, low priority parts i2,4, l, low priority parts i2,5,l (l=1., v);

		i_2,3,1[i_2,3,l]	Amplitude quantization relationship of strongest coefficients between polarizations.
i_2,4,1[i_2,4,l]	Amplitude quantization value of the coefficient corresponding to Taps.
		i_2,5,1[i_2,5,l]	The phase quantization value of the tap-corresponding coefficient.

2. Rel-16 CSI reporting mechanism based on physical uplink control channel (Physical Uplink Control Channel, PUCCH)

Periodic CSI reporting based on PUCCH formats 2, 3 and 4 supports wideband Type1CSI;

The semi-persistent CSI reporting based on the PUCCH supports Type1CSI;

the semi-persistent CSI reporting based on the PUCCH format2 supports wideband Type1CSI;

The semi-persistent CSI reporting based on the PUCCH format3 or 4 supports wideband and subband Type1CSI and Type2CSI Part1;

For the case where the subband Tytpe CSI is reported based on PUCCH format3 or 4, the CSI payload may be divided into two parts (Part 1 and Part 2), part1 including RI, CRI, part or all of the CQI corresponding to the first codeword, part2 including PMI and CQI corresponding to the second codeword (when RI >4, there are two codewords);

if one CSI report contains two parts, the UE may delete the content of Part2CSI, and the priority order is consistent with the priority table reported based on PUSCH.

3. Possible multi-TRP reporting formats

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

Wherein part1 comprises a CSI-RS resource Indication (CSI-RS resource indicator, CRI), a Rank Indication (RI), a Wideband (WB) channel quality Indication (Channel Quality Indicator, CQI) and a Subband (SB) CQI for a first codeword (Codeword, CW) and zero padding (if needed);

Wherein part2 comprises precoding matrix indicator (Precoding Matrix Indicator, PMI) related information.

4. Multi-TRP potential CSI reporting (reporting) mechanism

Regarding CSI reporting mechanisms, the current proposal (agreement) is as follows:

The following two modes are supported for one CSI report:

mode 1, a UE may be configured to report X Single TRP (STRP) measurement hypotheses and 1 NCJT measurement hypotheses, where x=0, 1, 2;

Mode 2 the UE is configured to select to report 1 optimal measurement hypothesis from all STRP measurement hypotheses and NCJT measurement hypotheses.

5. CSI reporting priority

The priority of CSI reporting is defined as Pri (y, k, c, s) =2·n _cells·M_s·y+N_cells·M_s·k+M_s ·c+s

Where y=0 denotes aperiodic CSI reporting based on PUSCH reporting, y=1 denotes semi-persistent CSI reporting based on PUSCH reporting, y=2 denotes semi-persistent CSI reporting based on PUCCH reporting, y=3 denotes periodic CSI reporting based on PUCCH reporting, k=0 denotes reporting of bearer L1-RSRP or L1-SINR, k=1 denotes reporting of non-bearer L1-RSRP or L1-SINR, c denotes serving cell index (cell index), N _cells denotes a value of higher layer parameter maxNrofServingCells, s denotes reportConfigID, ms denotes a value of higher layer parameter maxNrofCSI-ReportConfigurations.

Note that the lower the value of Pri (y, k, c, s), the higher the priority.

In order to solve the problem that the existing CSI reporting method and reporting format are not optimized according to two possible CSI reporting settings, and there may be a large feedback overhead or discarding more important CSI information, please refer to fig. 2, an embodiment of the present application provides a method for processing a multi-TRP CSI report, which includes:

Step 21, the terminal generates and reports a multi-TRP CSI report according to one CSI report setting (reporting setting) or according to a plurality of CSI report settings, wherein the multi-TRP CSI report is generated and/or reported in at least one of the following modes:

In the embodiment of the application, the generation and/or reporting process when the multi-TRP CSI report is generated according to two possible CSI report settings is optimized, so that the expenditure of the CSI report can be reduced or the effectiveness of the CSI report can be increased. In the embodiment of the present application, if the multi-TRP CSI report includes CSI of multiple measurement hypotheses, and at least two measurement hypotheses of the multiple measurement hypotheses can share a precoding matrix indication PMI, the multi-TRP CSI report includes only PMI of one measurement hypothesis of the at least two measurement hypotheses, that is, the terminal only needs to report PMI of one measurement hypothesis for the at least two measurement hypotheses, so that CSI reporting overhead can be reduced, and meanwhile, the network side applies the shared PMI to the at least two measurement hypotheses for data transmission.

In an embodiment of the present application, optionally, the multi-TRP CSI report includes a first field, where the first field is used to indicate whether the at least two measurement hypotheses share PMI. Optionally, the first domain is located at Part1 of the CSI report. Wherein the first field may be a bitmap (bitmap) indication or a code point (codepoint) or a switch identification (enable/disable/0/1/true/false). In the embodiment of the present application, optionally, if two or more PMIs corresponding to two or more CMRs of the multi-TRP CSI measurement hypothesis are shared with PMIs corresponding to CMRs of the single TRP measurement hypothesis, the first domain is used to indicate a correspondence relationship between PMIs sharing. The correspondence may be which PMI of two or more PMIs corresponding to two or more CMRs of a single TRP measurement hypothesis and a multi TRP CSI measurement hypothesis may be shared. In the case of two-level codebook, the PMI may be formed by the first-level codebook, or the first-level codebook and the second-level codebook may be formed together.

For example, the terminal indicates, by a bitmap (bitmap) of length K1 x K2, which of N measurement hypotheses (K1 Single TRP (STRP) measurement hypotheses, K2 multiple TRP (MTRP, including NCJT or JT) measurement hypotheses in the CSI report, and k1+k2=n) measurement hypotheses share the PMI. Specifically, assuming 2 STRP measurement hypotheses and 2 MTRP measurement hypotheses, if MTRP1 and (STRP 1 and STRP 2) can obtain a shared PMI according to a bitmap with a length of 4 (please refer to table 3, in table 3, 1 represents a shared PMI, and 0 represents a non-shared PMI), the terminal only reports MTRP1 or (STRP 1 and STRP 2) two PMIs and MTRP2 two PMIs, and the network side applies these four PMIs to these four measurement hypotheses for data transmission.

TABLE 3 Table 3

	STRP1	STRP2
			MTRP1	1	1
MTRP2	0	0

For example, the terminal indicates, by a bitmap (bitmap) of length K1 x K2, which of N measurement hypotheses (K1 Single TRP (STRP) measurement hypotheses, K2 multiple TRP (MTRP, including NCJT or JT) measurement hypotheses in the CSI report, and k1+k2=n) measurement hypotheses share the PMI. Specifically, assuming 2 STRP measurement hypotheses and 1 MTRP measurement hypothesis, wherein STRP1 corresponds to CMR1 and PMI1, STRP2 corresponds to CMR2 and PMI2, MTRP1 corresponds to CMR3, CMR4 and PMI3, PMI4, 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, and then MTRP1 and (STRP 1, STRP 2) can be obtained according to bitmap with length of 2 (please refer to table 3, in table 3, 1 indicates shared PMI,0 indicates not shared PMI), and PMIs can be shared by MTRP1 and (STRP 1, STRP 2), then the terminal only reports MTRP1 or (STRP 1, STRP 2), and the network side applies these two PMIs to these four measurement hypotheses for data transmission. Where the same resource refers to that a certain STRP measurement hypothesis uses the same CMR as a certain MTRP measurement hypothesis for the measurement, i.e. the network configures a certain CMR resource or resources and indicates that the CMR resource or resources can be used for both STRP measurement hypotheses and MTRP measurement hypotheses.

TABLE 3 Table 3

	STRP1	STRP2
			MTRP1	1	1

For example, the terminal indicates whether 3 measurement hypotheses (2 STRP measurement hypotheses, 1 MTRP measurement hypothesis) in the CSI report can share the PMI through the 1bit switch identification. If the MTRP1 and the STRP1 can share the PMI, the terminal only reports the MTRP1 or (STRP 1) and 2 PMIs of STRP2, and the network side applies the 2 PMIs to the three measurement hypotheses for data transmission. If it is indicated that PMI sharing is not possible, the terminal needs to report a total of4 PMIs for three measurement hypotheses.

For example, the terminal indicates whether 3 measurement hypotheses (2 STRP measurement hypotheses, 1 MTRP measurement hypothesis) in the CSI report can share PMI, wherein the STRP measurement hypothesis corresponds to one CMR and one PMI, and the MTRP measurement hypothesis corresponds to 2 CMRs and two PMIs, through codepoint (code points). Since a total of three measurement hypotheses are required, a total of 4 states are required, if the indication codepoint is 10, the first CMR of the MTRP measurement hypothesis and the PMI corresponding to the first CMR and the PMI of the first STRP measurement hypothesis can share the PMI, 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 3 PMIs, at this time, the first CMR representing 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, and the network side applies the 3 PMIs to the three measurement hypotheses for data transmission. If the indication codepoint is 01, the second CMR indicating the MTRP measurement hypothesis and the PMI corresponding to the second CMR may share the PMI, the terminal only reports the first PMI corresponding to the first CMR of the MTRP measurement hypothesis, the second PMI corresponding to the second CMR of the MTRP measurement hypothesis or the PMI of the second STRP measurement hypothesis, and the PMI of the first STRP measurement hypothesis, which are 3 total PMIs, where the second CMR indicating 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, and the network side applies the 3 PMIs to the three measurement hypotheses for data transmission. if the indication codepoint is 00, PMI sharing is not possible, and the terminal needs to report a total of 4 PMIs of three measurement hypotheses. If the indication codepoint is 11, the first CMR representing the MTRP measurement hypothesis and the PMI corresponding to the first PMI and the first STRP measurement hypothesis may share the PMI, the second CMR representing the MTRP measurement hypothesis and the PMI corresponding to the second CMR and the PMI corresponding to the second STRP measurement hypothesis may share the PMI, the terminal only reports the first PMI corresponding to the first CMR of the MTRP measurement hypothesis or the PMI corresponding to the first STRP measurement hypothesis, the second PMI corresponding to the second CMR of the MTRP measurement hypothesis or the PMI corresponding to the second STRP measurement hypothesis, 2 PMIs in total, at this time, the first CMR representing 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, the second CMR representing 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 resources, and the first CMR and the second CMR representing the MTRP measurement hypothesis and the second CMR corresponding to the second CMR are different CMR on the CMR side of the MTRP measurement hypothesis transmit data to the network hypothesis of the network of the application. where the same resource refers to that a certain STRP measurement hypothesis uses the same CMR as a certain MTRP measurement hypothesis for the measurement, i.e. the network configures a certain CMR resource or resources and indicates that the CMR resource or resources can be used for both STRP measurement hypotheses and MTRP measurement hypotheses.

For example, the terminal indicates whether 2 measurement hypotheses (1 STRP measurement hypothesis, 1 MTRP measurement hypothesis) in the CSI report can share PMI, wherein the STRP measurement hypothesis corresponds to one CMR and one PMI, and the MTRP measurement hypothesis corresponds to 2 CMRs and two PMIs, through codepoint (code points). Because of the total two measurement hypotheses, a sequence of 1bit length is needed, 2 states are totally needed, if the indication codepoint is 1, the target CMR of the MTRP measurement hypothesis and the corresponding target PMI and the PMI of the STRP measurement hypothesis can share the PMI, wherein 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 PMIs corresponding to CMRs except 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, 2 PMIs are totally indicated, and the network side applies the 2 PMIs to the two measurement hypotheses for data transmission. If the indication codepoint is 0, PMI sharing is not possible, the terminal needs to report a total of 3 PMIs of the two measurement hypotheses. Where the same resource refers to that a certain STRP measurement hypothesis uses the same CMR as a certain MTRP measurement hypothesis for the measurement, i.e. the network configures a certain CMR resource or resources and indicates that the CMR resource or resources can be used for both STRP measurement hypotheses and MTRP measurement hypotheses.

For example, the terminal indicates whether 2 measurement hypotheses (1 STRP measurement hypothesis, 1 MTRP measurement hypothesis) in the CSI report can share PMIs through codepoint (code point), wherein the STRP measurement hypothesis corresponds to one CMR and one PMI, the MTRP measurement hypothesis corresponds to 2 CMRs (first CMR and second CMR) and two PMIs, there may be 3 cases, so that a 2-bit length is required, that is, if the indication codepoint is 01, the first CMR of the MTRP measurement hypothesis and the PMI corresponding to the first CMR can share PMIs, the terminal only reports the PMIs corresponding to the second CMR of the MTRP measurement hypothesis, the PMIs corresponding to the first CMR of the MTRP measurement hypothesis or the PMIs of the STRP measurement hypothesis, 2 PMIs in total, and the network side applies these 2 PMIs to the two measurement hypotheses for data transmission. If the indication codepoint is 10, the second CMR indicating the MTRP measurement hypothesis and the PMI corresponding to the second CMR indicating the MTRP measurement hypothesis can share the PMI, and 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, 2 PMIs in total, and the network side applies the 2 PMIs to the two measurement hypotheses to transmit data. If the indication codepoint is 00, PMI sharing is not possible, the terminal needs to report a total of 3 PMIs of the two measurement hypotheses. Where the same resource refers to that a certain STRP measurement hypothesis uses the same CMR as a certain MTRP measurement hypothesis for the measurement, i.e. the network configures a certain CMR resource or resources and indicates that the CMR resource or resources can be used for both STRP measurement hypotheses and MTRP measurement hypotheses.

In the embodiment of the present application, if the multi-TRP CSI report includes CSI of multiple measurement hypotheses, and at least two measurement hypotheses of the multiple measurement hypotheses can share a precoding matrix indicator RI, the multi-TRP CSI report includes RI of only one measurement hypothesis of the at least two measurement hypotheses, that is, the terminal only needs to report RI of one measurement hypothesis for the at least two measurement hypotheses, so that CSI reporting overhead can be reduced, and meanwhile, the network side applies the shared RI to the at least two measurement hypotheses for data transmission.

In an embodiment of the present application, optionally, the multi-TRP CSI report includes a first field, where the first field is used to indicate whether the at least two measurement hypotheses share an RI. Optionally, the first domain is located at Part1 of the CSI report. Wherein the first field may be a bitmap (bitmap) indication or a code point (codepoint) or a switch identification (enable/disable/0/1/true/false).

In the embodiment of the present application, optionally, if two or more RIs corresponding to two or more CMRs of the multi-TRP CSI measurement hypothesis are shared with an RI corresponding to a CMR of the single TRP measurement hypothesis, the first domain is used to indicate a correspondence relationship between RI sharing. The correspondence may be which RI of two or more RIs corresponding to two or more CMRs of a single TRP measurement hypothesis may be shared with an RI corresponding to a multi TRP CSI measurement hypothesis.

For example, the terminal indicates, by a bitmap (bitmap) of length K1 x K2, which of N measurement hypotheses (K1 Single TRP (STRP) measurement hypotheses, K2 multiple TRP (MTRP, including NCJT or JT) measurement hypotheses in the CSI report, and k1+k2=n) measurement hypotheses share RI. Specifically, assuming 2 STRP measurement hypotheses and 2 MTRP measurement hypotheses, if MTRP1 and (STRP 1 and STRP 2) can be obtained according to a bitmap with a length of 4 (please refer to table 3, in table 3, 1 represents shared RI, and 0 represents non-shared RI), the terminal only reports MTRP1 or (STRP 1 and STRP 2) two RIs and MTRP2 two RIs, and the network side applies these four RIs to these four measurement hypotheses for data transmission.

For example, the terminal indicates, by a bitmap (bitmap) of length K1 x K2, which of N measurement hypotheses (K1 Single TRP (STRP) measurement hypotheses, K2 multiple TRP (MTRP, including NCJT or JT) measurement hypotheses in the CSI report, and k1+k2=n) measurement hypotheses share RI. Specifically, assuming 2 STRP measurement hypotheses and 1 MTRP measurement hypothesis, wherein STRP1 corresponds to CMR1 and RI1, STRP2 corresponds to CMR2 and RI2, MTRP1 corresponds to CMR3, CMR4 and RI3, and RI4, 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 MTRP1 and (STRP 1, STRP 2) can be obtained according to bitmap with length of 2 (please refer to table 3, in table 3, 1 indicates shared RI,0 indicates not shared RI), and RI can be shared, then the terminal only reports MTRP1 or (STRP 1, STRP 2) two RIs, and the network side applies these two RIs to these four measurement hypotheses for data transmission. Where the same resource refers to that a certain STRP measurement hypothesis uses the same CMR as a certain MTRP measurement hypothesis for the measurement, i.e. the network configures a certain CMR resource or resources and indicates that the CMR resource or resources can be used for both STRP measurement hypotheses and MTRP measurement hypotheses.

For example, the terminal indicates whether 3 measurement hypotheses (2 STRP measurement hypotheses, 1 MTRP measurement hypothesis) in the CSI report can share RI through the 1-bit switch identification. If the MTRP1 and the STRP1 can share RI, the terminal only reports MTRP1 or (STRP 1) and 2 RI of STRP2, and the network side applies these 2 RI to these three measurement hypotheses for data transmission. If RI sharing is indicated not to be possible, the terminal needs to report a total of 4 RIs for three measurement hypotheses.

For example, the terminal indicates whether 3 measurement hypotheses (2 STRP measurement hypotheses, 1 MTRP measurement hypothesis) in the CSI report, which correspond to one CMR and one RI, and 1 MTRP measurement hypothesis, which correspond to 2 CMRs and two RI, can share RI through codepoint (code points). Since a total of three measurement hypotheses are required, a sequence of 2bit length is required, if the indication codepoint is 10, it indicates that the first CMR of the MTRP measurement hypothesis and the RI corresponding to the first CMR and the RI of the first STRP measurement hypothesis can share the RI, 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, for a total of 3 RIs, where 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, and the network side applies the 3 RIs to the three measurement hypotheses for data transmission. If the indication codepoint is 01, the second CMR indicating the MTRP measurement hypothesis and the RI corresponding to the second CMR may share the RI with the RI corresponding to 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 corresponding to the second STRP measurement hypothesis, and the RI of the first STRP measurement hypothesis, for a total of 3 RIs, where the second CMR indicating 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, and the network side applies the 3 RIs to the three measurement hypotheses for data transmission. If the indication codepoint is 00, RI sharing is not possible, the terminal needs to report a total of 4 RIs for three measurement hypotheses. If the indication codepoint is 11, the first RI representing the MTRP measurement hypothesis and the RI corresponding to the first RI and the first STRP measurement hypothesis may share the RI, the second CMR representing the MTRP measurement hypothesis and the RI corresponding to the second RI and the RI corresponding to the second STRP measurement hypothesis may share the RI, the terminal only reports the first RI corresponding to the first CMR or the RI corresponding to the first STRP measurement hypothesis, the second RI corresponding to the second CMR of the MTRP measurement hypothesis or the RI corresponding to the second STRP measurement hypothesis, 2 RI in total, at this time, the first CMR representing 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, the second CMR representing 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, and the CMR corresponding to the second CMR of the MTRP measurement hypothesis and the second CMR are in the same resources, and the CMR corresponding to the first CMR and the second CMR of the MTRP measurement hypothesis and the second CMR are different from the CMR application side to the network side of the data is transmitted on the three hypothesis. where the same resource refers to that a certain STRP measurement hypothesis uses the same CMR as a certain MTRP measurement hypothesis for the measurement, i.e. the network configures a certain CMR resource or resources and indicates that the CMR resource or resources can be used for both STRP measurement hypotheses and MTRP measurement hypotheses.

For example, the terminal indicates whether 2 measurement hypotheses (1 STRP measurement hypothesis, 1 MTRP measurement hypothesis) in the CSI report, which correspond to one CMR and one RI, and 1 MTRP measurement hypothesis, which correspond to 2 CMRs and two RI, can share RI through codepoint (code points). Since two measurement hypotheses are totally added, a sequence with 1bit length is needed, if the indication codepoint is 1, the target CMR representing the MTRP measurement hypothesis and the RI of the corresponding target RI and the STRP measurement hypothesis can share RI, wherein 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 RI corresponding to the CMR except 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, 2 RI are totally added, and the network side applies the 2 RI to the two measurement hypotheses for data transmission. If the indication codepoint is 0, RI sharing is not possible, the terminal needs to report a total of 3 RIs for both measurement hypotheses. Where the same resource refers to that a certain STRP measurement hypothesis uses the same CMR as a certain MTRP measurement hypothesis for the measurement, i.e. the network configures a certain CMR resource or resources and indicates that the CMR resource or resources can be used for both STRP measurement hypotheses and MTRP measurement hypotheses.

If multiple CSI reports exist on the uplink resource for carrying the multiple TRP CSI reports, and the uplink resource can simultaneously carry the reporting of the multiple CSI reports, no discard rule is triggered.

In the embodiment of the application, the CSI information with high effectiveness is reported on limited uplink resources by defining the discarding rule of the CSI information carried in the MTRP CSI report, so that the effectiveness of the MTRP CSI report is improved.

In an embodiment of the present application, optionally, the discarding rule includes:

if the reporting resource cannot bear the reporting of the multiple CSI reports at the same time, discarding the CSI information of the target CSI report with the lowest current priority in the multiple CSI reports according to one of the following conditions until the reporting resource can meet the reporting of the CSI report:

Discarding the CSI of the target measurement hypothesis in the target CSI report according to the CQI;

And discarding the CSI of the target measurement hypothesis in the target CSI report according to the RI and the CQI.

In the embodiment of the present application, the target measurement hypothesis may be 1 or more measurement hypotheses in the target CSI report.

For example, there are 3 CSI reports on the reporting resource, where the transmission priority of CSI report 1, CSI report 2 and CSI report 3 is higher than that of CSI report 2, and the transmission priority of CSI report 2 is higher than that of CSI report 3, and if the reporting resource cannot simultaneously carry the reporting of the 3 CSI reports, firstly, the CSI information of the CSI report 3 with the lowest current priority is discarded, and according to RI, CQI, or RI and CAI, the CSI information of the target measurement hypothesis in CSI report 3 may be discarded until the reporting resource can carry the reporting of the CSI report. If the CSI information of all measurement hypotheses in the CSI report 3 is discarded, reporting resources cannot bear reporting of the CSI report at the same time, discarding the CSI information of the CSI report 2 with the lowest current priority, and so on until the reporting resources can bear reporting of the CSI report.

Namely, firstly discarding the CSI of the measurement hypothesis with the lowest RI in the target CSI report, and if the reporting resource still cannot meet the reporting requirement of the CSI report, continuing discarding the CSI of the measurement hypothesis with the lowest RI in the target CSI report.

In the embodiment of the 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 according to the order of CQI from low to high. Namely, firstly discarding the CSI of the measurement hypothesis with the lowest CQI in the target CSI report, and if the reporting resource still cannot meet the reporting requirement of the CSI report, continuing discarding the CSI of the measurement hypothesis with the lowest current CQI in the target CSI report.

In some embodiments of the present application, further optionally, the discarding rule further includes:

Discarding CSI information of a target measurement hypothesis in the target CSI report in the following order:

odd subband CSI information of the target measurement hypothesis;

even subband CSI information of the target measurement hypothesis;

the target measures hypothesized wideband CSI information.

Namely, firstly discarding odd subband CSI information of a target measurement hypothesis, discarding even subband CSI information of the target measurement hypothesis if uplink resources cannot meet the reporting requirement of the CSI report, and discarding wideband CSI information of the target measurement hypothesis if the uplink resources cannot meet the reporting requirement of the CSI report.

The above-described manner of dropping in order of odd subband CSI information, even subband CSI information, and wideband CSI information is applicable to the above-described three scenarios of dropping according to RI, dropping according to CQI, and/or dropping CSI information of a target measurement hypothesis in the target CSI report according to RI and CQI.

For example, 3 CSI reports exist on the reporting resource, the transmission priority of CSI report 1, CSI report 2 and CSI report 3 is higher than that of CSI report 2, the transmission priority of CSI report 2 is higher than that of CSI report 3, if the reporting resource cannot simultaneously carry the reporting of the 3 CSI reports, firstly, the CSI information of the CSI report 3 with the lowest current priority is discarded, and the CSI information of the target measurement hypothesis in CSI report 3 can be discarded according to RI, CQI or RI and CAI, wherein when the CSI information of the target measurement hypothesis in CSI report 3 is discarded, the odd subband CSI information of the target measurement hypothesis can be discarded first, then the even subband CSI information of the target measurement hypothesis is discarded, and finally the order of the wideband CSI information of the target measurement hypothesis is discarded until the reporting resource can carry the reporting of the CSI report. If the discarding of the CSI information of all measurement hypotheses in the CSI report 3 is completed, the reporting resource cannot still carry the reporting of the CSI report at the same time, the CSI information of the CSI report 2 with the lowest current priority is discarded (see the CSI report 3 for discarding mode), and so on until the reporting resource can carry the reporting of the CSI report.

odd subband CSI information of the target measurement hypothesis;

the target measures hypothetical even subband CSI information.

Namely, the odd subband CSI information of the target measurement hypothesis is discarded first, and if the uplink resource cannot meet the reporting requirement of the CSI report, the even subband CSI information of the target measurement hypothesis is discarded. Further optionally, if the reporting resource still cannot simultaneously carry the reporting of the CSI report after the subband CSI information of all measurement hypotheses in the target CSI report is discarded, the wideband CSI information of all measurement hypotheses in the target CSI report is discarded.

In this embodiment, the three scenarios of CSI information of the target measurement hypothesis in the target CSI report are also discarded based on RI discard, CQI discard, and/or RI and CQI discard as described above.

For example, 3 CSI reports exist on the reporting resource, the transmission priority of CSI report 1, CSI report 2 and CSI report 3 is higher than that of CSI report 2, the transmission priority of CSI report 2 is higher than that of CSI report 3, if the reporting resource cannot simultaneously carry the reporting of the 3 CSI reports, firstly, the CSI information of the CSI report 3 with the lowest current priority is discarded, and the CSI information of the target measurement hypothesis in CSI report 3 can be discarded according to RI, CQI or RI and CAI, wherein when the CSI information of the target measurement hypothesis in CSI report 3 is discarded, the CSI information of the odd subband of the target measurement hypothesis can be discarded first, and then the CSI information of the even subband of the target measurement hypothesis is discarded until the reporting resource can carry the reporting of the CSI report. If the discarding of the sub-band CSI information of all measurement hypotheses in the CSI report 3 is completed, the reporting resource cannot simultaneously carry the reporting of the CSI report, and the wideband CSI information of all measurement hypotheses in the CSI report 3 is discarded. If the reporting resource cannot still bear the reporting of the CSI report at the same time, the CSI information of the CSI report 2 with the lowest current priority is discarded (the discarding mode is referred to as CSI report 3), and so on until the reporting resource can bear the reporting of the CSI report.

odd subband CSI information of the target measurement hypothesis;

the target measures hypothetical even subband CSI information.

Namely, the odd subband CSI information of the target measurement hypothesis is discarded first, and if the uplink resource cannot meet the reporting requirement of the CSI report, the even subband CSI information of the target measurement hypothesis is discarded. Further optionally, if the reporting resource cannot still simultaneously carry the reporting of the CSI report after the subband CSI information of all measurement hypotheses in all CSI reports is discarded, the wideband CSI information of all measurement hypotheses in all CSI reports is discarded.

For example, 2 CSI reports exist on the reporting resource, the transmission priority of CSI report 1 and CSI report 2 is higher than that of CSI report 2, if the reporting resource cannot simultaneously carry the reporting of the 2 CSI reports, firstly, the CSI information of the CSI report 2 with the lowest current priority is discarded, and the CSI information of the target measurement hypothesis in CSI report 2 can be discarded according to RI, CQI, or RI and CAI, wherein when the CSI information of the target measurement hypothesis in CSI report 2 is discarded, 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 is discarded until the reporting resource can carry the reporting of the CSI report. If the discarding of the sub-band CSI information of all measurement hypotheses in CSI report 2 is completed, reporting resources cannot still carry reporting of the CSI report at the same time, and discarding the sub-band CSI information of all measurement hypotheses in CSI report 1. And if the reporting resource cannot bear the reporting of the CSI report at the same time, discarding wideband CSI information of all measurement hypotheses in the CSI report 1 and the CSI report 2.

In some embodiments of the application, optionally, the discarding rule comprises:

If the reporting resource cannot bear the reporting of the plurality of CSI reports at the same time, discarding sub-band CSI information in the CSI reports according to the sequence from low priority to high priority of the plurality of CSI reports, wherein the sub-band CSI information of each CSI report comprises odd sub-band CSI information and even sub-band CSI information, and discarding the sub-band CSI information in the CSI reports according to the sequence of the odd sub-band CSI information of all measurement hypotheses and the even sub-band CSI information of all measurement hypotheses when the sub-band CSI information in the CSI reports is discarded until the reporting resource can meet the reporting of the CSI reports;

if the reporting resource still cannot bear the reporting of the CSI report at the same time after all the subband CSI information of the CSI report is discarded, discarding all the wideband CSI information in the plurality of CSI reports, wherein each wideband CSI information corresponds to 1 CSI report.

For example, 2 CSI reports exist on the reporting resource, the transmission priority of CSI report 1 and CSI report 2 is higher than that of CSI report 2, if the reporting resource cannot simultaneously carry the reporting of the 2 CSI reports, the subband CSI information of the CSI report 2 with the lowest current priority is discarded first, where when the subband CSI information in CSI report 2 is discarded, the odd subband CSI information of all measurement hypotheses may be discarded first, and then the even subband CSI information of all measurement hypotheses may be discarded until the reporting resource can carry the reporting of the CSI report. If the discarding of the sub-band CSI information of all measurement hypotheses in CSI report 2 is completed, reporting resources cannot still carry reporting of the CSI report at the same time, and discarding the sub-band CSI information of all measurement hypotheses in CSI report 1. And if the reporting resource cannot bear the reporting of the CSI report at the same time, discarding wideband CSI information of all measurement hypotheses in the CSI report 1 and the CSI report 2.
