Description

Method and device for processing multiple TRP CSI reports

Technical Field

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

Background

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

The multiple TRPs can be divided into ideal backhaul (ideal backhaul) and non-ideal backhaul (non-ideal backhaul).

When the backhaul is not an ideal backhaul, the interaction Information among multiple TRPs has a large delay, which is more suitable for independent scheduling, and positive acknowledgement/negative acknowledgement (ACK/NACK) and Channel State Information (CSI) reports are fed back to each TRP respectively. The method is generally applicable to multiple Downlink Control Information (DCI) scheduling, that is, each TRP transmits a Physical Downlink Control Channel (PDCCH), each PDCCH schedules a Physical Downlink Shared Channel (PDSCH), and a plurality of Control Resource sets (core sets ) configured for the UE are associated with different Radio Resource Control (RRC) parameter Control Resource set pool indexes (core _ pool indexes) and correspond to different TRPs. Multiple PDSCHs scheduled by multiple DCIs may be non-overlapping, partially overlapping, and completely overlapping on time-frequency resources. On the overlapped time-frequency resources, each TRP performs independent precoding according to its own channel, and the UE receives a multi-layer data stream belonging to multiple PDSCHs in a Non-Coherent Joint Transmission (NCJT) manner.

In an ideal backhaul, scheduling information and feedback information of the UE may be exchanged between multiple TRPs in real time, and besides scheduling multiple PDSCHs through the multiple DCI, a single DCI may also be used to schedule the PDSCH, including the following transmission schemes:

space Division Multiplexing (SDM): different data layers of the same Transport Block (TB) are from NCJT transmissions of different TRPs;

frequency-division multiplexing (FDM): different frequency domain resources mapped by the same TB and the same Redundancy Version (RV) are sent from different TRPs or different RVs of the same TB are mapped to different frequency domain resources and sent from different TRPs;

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

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

Rel-17 specifically defines multiple TRPs/multiple panels from the aspects of CSI report setting, report content, CSI resource configuration and the like, and mainly comprises the following methods:

1) Configuring a plurality of CSI report settings (Reporting setting), wherein the resource setting (resource setting) of each CSI report setting corresponds to one TRP, namely each CSI report setting corresponds to one CSI report of the TRP.

2) The base station configures one CSI report setting, defaults to or instructs joint (common) calculation of one CSI report by 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 where feedback overhead is large or more important CSI information is discarded.

The following first presents a brief description of the communications vocabulary associated with the present application.

1. Physical Uplink Shared Channel (PUSCH) -based CSI reporting mechanism of Rel-16

The CSI supports Type1 (Type 1) wideband or subband CSI and also supports Type2 (Type 2) CSI based on PUSCH reporting.

For Type1, type2 and enhanced Type2CSI based on PUSCH feedback, one CSI report (report) consists of two parts (Part 1 and Part 2), where Part1 has a fixed load size while indicating the number of information bits (bit) of Part2, noting that: part1 is transmitted all before Part 2.

For Type1CSI feedback, part1 may include one or more of Rank Indication (RI), CSI-RS resource Indication (CRI), channel Quality Indication (CQI) of a first codeword, and Part2 includes one or more of Precoding Matrix Indication (PMI) and CQI of a second codeword;

for Type2CSI feedback, part1 comprises one or more items of RI, CQI and indication of each layer of nonzero wideband amplitude coefficient of Type2CSI, and Part2 comprises PMI of Type2 CSI;

for enhanced Type2CSI feedback, part1 includes indication of RI, CQI, and total number of enhanced Type2CSI cross-layer nonzero amplitude coefficients, and Type2 includes PMI of enhanced Type2 CSI;

when the CSI reported based on the PUSCH includes Part1 and Part2, the UE may delete Part of the Part2CSI content, and the deletion rule of Part2 is shown in table 1 and table 2 in order of priority from high to low.

Wherein, for the enhanced Type2CSI report, group 0 includes indices i1,1, i1,2 and i1,8,l (l =1, \8230;, v); group1 contains the indices i1,5 (if reported), i1,6,l, high priority section i1,7,l, i2,3,l, high priority section i2,4,l, high priority section i2,5,l (l =1, \8230;, v); group2 comprises low priority portions i1,7, l, low priority portions i2,4, l, low priority portions i2,5, l (l =1, \8230;, v);

TABLE 1

TABLE 2

Amount of feedback	Means of
		i _2,3,1 [i _2,3,l ]	The magnitude of the strongest coefficient between polarizations quantifies the relationship.
i _2,4,1 [i _2,4,l ]	Magnitude quantization values of coefficients corresponding to Taps.
		i _2,5,1 [i _2,5,l ]	The phase quantization values of the coefficients corresponding to Taps.

2. Physical Uplink Control Channel (PUCCH) -based CSI reporting mechanism of Rel-16

The periodic CSI reporting based on PUCCHs format2, 3 and 4 supports wideband Type1CSI;

the semi-continuous CSI based on the PUCCH reports the Type1CSI;

the semi-continuous CSI based on PUCCH format2 reports and supports wideband Type1CSI;

the method comprises the steps that a PUCCH format3 or 4-based semi-continuous CSI report supports wideband and sub-band Type1CSI and Type2CSI Part1;

for the case that the sub-band type1CSI is reported based on PUCCH format3 or 4, the CSI load may be divided into two parts (Part 1 and Part 2), where Part1 includes RI, CRI, and Part or all of CQI corresponding to the first codeword, and Part2 includes PMI and CQI corresponding to the second codeword (when RI >4, there are two codewords);

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

3. Possible multiple TRP report formats

Rel-17 supports a CSI report consisting of two parts (Part 1 and Part 2) for CSI report settings related to the NCJT measurement hypothesis.

Wherein part1 includes a CSI-RS resource Indicator (CRI), a Rank Indicator (RI), a Wideband (WB) Channel Quality Indicator (CQI), a Subband (SB) CQI, and zero padding (if needed) of a first Codeword (CW);

wherein part2 includes Precoding Matrix Indicator (PMI) related information.

4. Potential CSI reporting (reporting) mechanism for multiple TRPs

With regard to the CSI reporting mechanism, the current proposal (element) is as follows:

the following two approaches are supported for one CSI report:

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

mode 2: the configuration UE selects to report 1 optimal measurement hypothesis from all the 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

Wherein y =0 denotes an aperiodic CSI report based on a PUSCH report, y =1 denotes a semi-persistent CSI report based on a PUSCH report, and y =2 denotes a PUCCH report based on a PUCCH reportSemi-persistent CSI report, y =3 denotes periodic CSI report based on PUCCH report, k =0 denotes report carrying L1-RSRP or L1-SINR, k =1 denotes report not carrying L1-RSRP or L1-SINR, c denotes serving cell index (cell index), N _cells Indicating the value of the high-level parameter maxNrofServingCells, s indicating reportConfigID, ms indicating the value of the high-level parameter maxNrofCSI-ReportConfigurations.

Note that: the lower the Pri (y, k, c, s) value, 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 problem of a relatively high feedback overhead or a relatively important CSI information discarded, referring to fig. 2, an embodiment of the present application provides a method for processing a multi-TRP CSI report, including:

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

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

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

For example, the terminal indicates, through one bitmap (bitmap) with length K1 × K2, which MTRP measurement hypotheses of N measurement hypotheses (K1 Single TRP (STRP) measurement hypotheses, K2 multiple TRP (MTRP, including NCJT or JT) measurement hypotheses, and K1+ K2= N) in the CSI report and the STRP measurement hypotheses share the PMI. Specifically, assuming 2 STRP measurement hypotheses and 2 MTRP measurement hypotheses, the shared PMIs of MTRP1 and (STRP 1, STRP 2) may be obtained 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 an unshared PMI), and the terminal only reports two PMIs of MTRP1 or (STRP 1, STRP 2) and two PMIs of MTRP2, and the network side applies the four PMIs to the four measurement hypotheses for data transmission.

TABLE 3

	STRP1	STRP2
			MTRP1	1	1
MTRP2	0	0

For example, the terminal indicates, through one bitmap (bitmap) with length K1 × K2, which MTRP measurement hypotheses of N measurement hypotheses (K1 Single TRP (STRP) measurement hypotheses, K2 multiple TRP (MTRP, including NCJT or JT) measurement hypotheses, and K1+ K2= N) in the CSI report and the STRP measurement hypotheses share the PMI. Specifically, 2 STRP measurement hypotheses and 1 MTRP measurement hypothesis are assumed, where STRP1 corresponds to CMR1 and PMI1, STRP2 corresponds to CMR2 and PMI2, MTRP1 corresponds to CMR3, CMR4, PMI3 and 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 a bitmap with a length of 2 (please refer to table 3, where 1 indicates shared PMI, and 0 indicates unshared PMI), it is possible to obtain that STRP1 and (STRP 1 and STRP 2) can share PMI, and then the terminal only reports two PMIs MTRP1 or (STRP 1 and STRP 2), and the network side applies the two PMIs to the four measurement hypotheses to transmit data. The same resource refers to 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 the CMR resource or resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

TABLE 3

	STRP1	STRP2
			MTRP1	1	1

For example: the terminal indicates whether 3 measurement hypotheses (2 STRP measurement hypotheses and 1 MTRP measurement hypothesis) in the CSI report can share the PMI through the 1-bit switch identifier. If the MTRP1 and the STRP1 can share the PMI, the terminal only reports the MTRP1 or (STRP 1) and 2 PMIs of the STRP2, and the network side applies the 2 PMIs to the three measurement hypotheses for data transmission. If the PMI sharing cannot be performed, the terminal needs to report 4 PMIs in total of three measurement hypotheses.

For example: the terminal indicates whether 3 measurement hypotheses (2 STRP measurement hypotheses and 1 MTRP measurement hypothesis) in the CSI report can share the PMI through codepoint, wherein the STRP measurement hypotheses correspond to one CMR and one PMI, and the MTRP measurement hypotheses correspond to 2 CMRs and two PMIs. Since three measurement assumptions are totally counted, a sequence with a length of 2 bits is needed, 4 states are totally counted, if the codepoint is indicated to be 10, a first CMR representing the MTRP measurement assumption and a corresponding first PMI thereof and a PMI of the first STRP measurement assumption can share a PMI, the terminal only reports a second PMI corresponding to a second CMR of the MTRP measurement assumption, the first PMI corresponding to the first CMR of the MTRP measurement assumption or the PMI of the first STRP measurement assumption and the PMI of the second STRP measurement assumption, 3 PMIs are totally counted, at this time, the first CMR representing 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 3 PMIs applied to the three measurement assumptions by the network side for data transmission. If codepoint is indicated to be 01, the second CMR representing the MTRP measurement hypothesis and the corresponding second PMI thereof and the PMI of the second STRP measurement hypothesis can 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, 3 PMIs are counted, at this time, 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 resource, and the 3 PMIs are applied to the three measurement hypotheses by the network side for data transmission. If codepoint is indicated to be 00, PMI sharing cannot be carried out, and the terminal needs to report 4 PMIs in total of three measurement hypotheses. If codepoint is indicated to be 11, the first CMR representing the MTRP measurement hypothesis and the corresponding first PMI thereof and the first PMI of the STRP measurement hypothesis can share the PMI, the second CMR representing the MTRP measurement hypothesis and the corresponding second PMI thereof and the PMI of the second STRP measurement hypothesis can share the PMI, the terminal only reports the first PMI corresponding to the first CMR of the MTRP measurement hypothesis or the PMI of the first STRP measurement hypothesis, the PMI corresponding to the second CMR of the MTRP measurement hypothesis or the PMI of the second STRP measurement hypothesis can report 2 PMI in total, at the moment, the first CMR representing the MTRP measurement hypothesis and the CMR corresponding to the first CMR have the same ID or are in the same CMR group or are in the same resource, 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 in the same resource, and the first CMR and the second PMI of the MTRP measurement hypothesis and the CMR are applied to the CMR side for transmitting data on the three different CMRs. 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 the one or several CMR resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

For example: the terminal indicates whether 2 measurement hypotheses (1 STRP measurement hypothesis and 1 MTRP measurement hypothesis) in the CSI report can share the PMI through codepoint, wherein the STRP measurement hypothesis corresponds to one CMR and one PMI, and the MTRP measurement hypothesis corresponds to 2 CMRs and two PMIs. Because two measurement hypotheses are counted, a sequence with the length of 1bit is needed, 2 states are counted, if codepoint is indicated to be 1, the target CMR of the MTRP measurement hypothesis and the corresponding target PMI thereof 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 PMI corresponding to the CMR of the MTRP measurement hypothesis except the target CMR, the target PMI corresponding to the target CMR of the MTRP measurement hypothesis or the PMI of the STRP measurement hypothesis, 2 PMIs are counted, and the 2 PMIs are applied to the two measurement hypotheses by the network side for data transmission. If the codepoint is indicated to be 0, PMI sharing cannot be performed, and the terminal needs to report 3 PMIs in total of two measurement assumptions. The same resource refers to 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 the CMR resource or resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

For example: the terminal indicates whether 2 measurement hypotheses (1 STRP measurement hypothesis and 1 MTRP measurement hypothesis) in a CSI report can share the PMI through a codepoint, wherein the STRP measurement hypothesis corresponds to one CMR and one PMI, the MTRP measurement hypothesis corresponds to 2 CMRs (a first CMR and a second CMR) and two PMIs, there may be 3 cases, and therefore a 2-bit length is required, that is, if the codepoint is indicated to be 01, the first CMR representing the MTRP measurement hypothesis and the corresponding PMI thereof and the PMI of the STRP measurement hypothesis can share the PMI, 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 are measured by the terminal, 2 PMIs counted, and the 2 PMIs applied to the two measurement hypotheses by the network side for data transmission. If the codepoint is indicated to be 10, the PMI of the second CMR and the corresponding PMI of the second CMR representing the MTRP measurement hypothesis and the PMI of the STRP measurement hypothesis can share the PMI, 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 are measured by the MTRP, 2 PMIs are counted, and the 2 PMIs are applied to the two measurement hypotheses by the network side for data transmission. If codepoint is indicated to be 00, PMI sharing cannot be performed, and the terminal needs to report 3 PMIs in total of 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 the one or several CMR resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

In the embodiment of the present application, if the multiple 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 multiple TRP CSI report only includes an RI of one measurement hypothesis of 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, 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 this 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 hypotheses share the RI. Optionally, the first field is located in Part1 of the CSI report. Wherein the first field may be a bitmap (bitmap) indication or a codepoint (codepoint) or a switch identifier (enable/disable/0/1/true/false).

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

For example, the terminal indicates, through one bitmap (bitmap) of length K1 × K2, which of N measurement hypotheses (K1 Single TRP (STRP) measurement hypotheses, K2 multiple TRP (MTRP, including NCJT or JT) measurement hypotheses, and K1+ K2= N) of the CSI report share the RI. Specifically, assuming 2 STRP measurement hypotheses and 2 MTRP measurement hypotheses, then, according to a bitmap with a length of 4 (please refer to table 3, in table 3, 1 indicates shared RI, and 0 indicates unshared RI), MTRP1 and (STRP 1, STRP 2) sharable RI can be obtained, and the terminal only reports MTRP1 or two RIs (STRP 1, STRP 2) and two RI of MTRP2, and the network side applies the four RIs to the four measurement hypotheses to perform data transmission.

For example, the terminal indicates, through one bitmap (bitmap) of length K1 × K2, which of N measurement hypotheses (K1 Single TRP (STRP) measurement hypotheses, K2 multiple TRP (MTRP, including NCJT or JT) measurement hypotheses, and K1+ K2= N) of the CSI report share the RI. Specifically, 2 STRP measurement hypotheses and 1 MTRP measurement hypothesis are assumed, 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, CMR2 and CMR4 are in the same CMR group or have the same CMR ID or are the same resource, then according to a bitmap with a length of 2 (please refer to table 3, where 1 indicates shared RI, and 0 indicates unshared RI), MTRP1 and (STRP 1, STRP 2) can obtain shared RI, and the terminal only reports two MTRP1 or (STRP 1, STRP 2), and the network side applies the two to the four measurement hypotheses to send data on the four 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 the one or several CMR resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

For example: the terminal indicates whether 3 measurement hypotheses (2 STRP measurement hypotheses, 1 MTRP measurement hypothesis) in the CSI report can share the RI through the 1-bit switch identifier. If the indication that MTRP1 and STRP1 can share RI indicates that the terminal only reports MTRP1 or (STRP 1) and 2 RIs of STRP2, the network side applies the 2 RIs to the three measurement hypotheses for data transmission. If the indication indicates that RI sharing is not possible, the terminal needs to report a total of 4 RIs of the 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 the RI through codepoint, where the STRP measurement hypotheses correspond to one CMR and one RI, and the MTRP measurement hypotheses correspond to 2 CMRs and two RIs. Because three measurement assumptions are counted, a sequence with a length of 2 bits is needed, if codepoint is indicated to be 10, a first CMR representing the MTRP measurement assumption and a corresponding first RI thereof and an RI of a first STRP measurement assumption can share the RI, the terminal only reports a second RI corresponding to a second CMR of the MTRP measurement assumption, the first RI corresponding to the first CMR of the MTRP measurement assumption or the RI of the first STRP measurement assumption, and the RI of the second STRP measurement assumption and 3 RIs in total, at this time, the first CMR representing 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 network side applies the 3 RIs to the three measurement assumptions for data transmission. If the codepoint is 01, the second CMR representing the MTRP measurement hypothesis and the corresponding second RI thereof and the second RI of the STRP measurement hypothesis may share the RI, 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, which total 3 RIs, when 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 resource, the network side applies the 3 RIs to the three measurement hypotheses for data transmission. If codepoint is indicated to be 00, then RI sharing is not possible, and the terminal needs to report 4 RIs in total of three measurement hypotheses. If codepoint is indicated to be 11, the first CMR representing the MTRP measurement hypothesis and the corresponding first RI thereof and the RI of the first STRP measurement hypothesis can share RI, the second CMR representing the MTRP measurement hypothesis and the corresponding second RI thereof and the RI of the second STRP measurement hypothesis can share RI, the terminal only reports the first RI corresponding to the first CMR of the MTRP measurement hypothesis or the RI of the first STRP 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 2 RIs in total, at the moment, 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 in the same resource, 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 resource, and the first CMR and the second CMR of the MTRP measurement hypothesis and the CMR belong to the CMR group or are in the same resource, and the CMR group, and the CMR side sending data on three different sides. The same resource refers to 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 the CMR resource or resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

For example: the terminal indicates whether 2 measurement hypotheses (1 STRP measurement hypothesis and 1 MTRP measurement hypothesis) in the CSI report can share the RI through codepoint, where the STRP measurement hypothesis corresponds to one CMR and one RI, and the MTRP measurement hypothesis corresponds to 2 CMRs and two RIs. Because two measurement assumptions are counted, a sequence with a length of 1bit is needed, if codepoint is indicated to be 1, it indicates that a target CMR of the MTRP measurement assumption and a target RI corresponding to the target CMR and an RI of the STRP measurement assumption can share the RI, where the target CMR and the CMR corresponding to the STRP measurement assumption 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 of the MTRP measurement assumption except the target CMR, the target RI corresponding to the target CMR of the MTRP measurement assumption or the RI of the STRP measurement assumption, 2 RIs are counted, and the network side applies the 2 RIs to the two measurement assumptions for data transmission. If codepoint is indicated to be 0, then RI sharing is not possible, and the terminal needs to report a total of 3 RIs 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 the one or several CMR resources can be used for both the STRP measurement hypothesis and the MTRP measurement hypothesis.

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 all CSI reports is discarded, the wideband CSI information of all measurement hypotheses in all CSI reports is discarded.

For example: if the reporting resource cannot simultaneously carry the reporting of the 2CSI reports, the CSI information of the CSI report 2 with the lowest priority is discarded, the CSI information of a target measurement hypothesis in the 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 the CSI report 2 is discarded, the odd-numbered sub-band CSI information of the target measurement hypothesis can be discarded first, and then the even-numbered sub-band CSI information of the target measurement hypothesis is discarded until the reporting resource can carry the reporting of the CSI reports. And if the discarding of the sub-band CSI information of all the measurement hypotheses in the CSI report 2 is finished and the reporting resource still cannot simultaneously carry the reporting of the CSI report, discarding the sub-band CSI information of all the measurement hypotheses in the CSI report 1. And if the reporting resource still cannot simultaneously carry the reporting of the CSI report, discarding the broadband CSI information of all the measurement hypotheses in the CSI report 1 and the CSI report 2.
