[0033] In order to better understand the technical solution provided by this application, the relevant technologies involved in this application are first introduced.

[0034] 1. CSI Architecture

[0035] Generally, the CSI architecture can be divided into two parts: downlink CSI and uplink CSI. Downlink CSI architecture: includes downlink physical channels and downlink reference signals; uplink CSI architecture: includes uplink physical channels and uplink reference signals.

[0036] The downlink physical channel is usually used to transmit data, and the downlink reference signal is usually used to perform channel estimation to obtain downlink channel state information (CSI). The uplink physical channel is usually used to transmit uplink data, and the uplink reference signal is usually used to perform channel estimation to obtain uplink channel state information (CSI).

[0037] In 5G systems, CSI is mainly used in Adaptive Beamforming and MIMO (Multiple Input Multiple Output) technologies to improve wireless transmission bandwidth and reliability.

[0038] In general, the 5G CSI architecture is a very important technology in the 5G communication system, and plays an important role in improving wireless transmission bandwidth and reliability and interference coordination.

[0039] 2. Contents of CSI Report

[0040] Typically, the terminal may determine through higher-layer signaling or default rules that a CSI report may include one of: 'none', 'cri-ri-pmi-cqi', 'cri-RI-i1', 'cri-RI-CQI', 'cri-RSRP', 'cri-SINR', 'ssb-Index-RSRP', 'ssb-Index-SINR' or 'cri-RI-LI-PMI-CQI'.

[0041] If the terminal is configured with CSI-ReportConfig and the upper layer parameter reportQuantity is set to "none", the terminal will not report anything for CSI-ReportConfig.

[0042] 3. CSI acquisition

[0043] The network associates a reference signal resource configuration (CSI-ResourceConfig) for channel measurement, a reference signal resource configuration for interference measurement associated with a CSI-IM (CSI interference measurement) resource, and or a reference signal resource configuration for interference measurement associated with an NZP-CSI RS (non-zero power CSI-RS) resource for each CSI report configuration (CSI-ReportConfig). The terminal obtains the corresponding channel information by measuring the reference resources associated with these resource configurations. Currently, the corresponding channel information can usually be considered as baseband digital precoding matrix information and baseband modulation mode recommendation information. Further, according to the codebook configuration information and report content associated with the CSI report configuration, the corresponding CSI information is obtained, and based on the uplink channel feedback.

[0044] For PMI feedback, if the Rel-15 Type1 codebook configuration is used, the terminal measures up to 8 channel measurement reference signals and selects one of the reference signals to feedback PMI. If the Rel-15 Type2 / Rel-16 Type2 / Rel-17 codebook is used, the terminal measures 1 channel measurement reference signal and feedbacks the PMI associated with the reference signal. If the Rel-18 Type2 coherent joint transmission (CJT) codebook is used, the terminal measures up to 4 channel measurement reference signals, assumes that the 4 reference signals are associated with 4 TRPs, and uses the channels associated with the 4 reference signals to obtain and feedback PMI. If it is Rel-18 Type2 prediction codebook, for periodic / semi-continuous channel measurement reference signals, the network side device configures 1 reference signal, and the terminal uses multiple transmission times of one reference signal to obtain the predicted PMI. For non-periodic channel measurement reference signals, the network side device configures up to 12 reference signals. The 12 reference signals are sent at a certain interval in time, and the terminal uses one transmission time of the 12 reference signals to obtain the predicted PMI.

[0045] In addition, if CJT CSI is obtained, the delay offset between two TRPs that the terminal can feedback is 1 / B*N3, where B is the CSI reference signal bandwidth and N3 is the number of PMI subbands, which means that if the delay offset between two TRPs exceeds this range, the performance of the PMI obtained by the terminal will deteriorate. In other words, the network side device cannot obtain the delay offset between two TRPs through PMI.

[0046] For the CSI associated with the Rel-15 Type2 / Rel-16 Type2 / Rel-17 codebook, it may be divided into two parts, namely Part 1 and Part 2. The two parts are encoded independently. By interpreting the content of Part 1 of a CSI report, the network side device can determine the size of Part 2 of the CSI report.

[0047] However, there is no CSI report feedback framework in the related art to support the terminal to assist the network side device in time synchronization or timing synchronization or frequency alignment. To address this problem, the embodiments of the present application provide a method for obtaining a channel state information report, a terminal and a network side device.

[0048] The following, in combination with the accompanying drawings, describes in detail the channel state information report acquisition scheme provided in the embodiments of the present application through some embodiments and their application scenarios.

[0049] Figure 2A flow chart of a method for acquiring a channel state information report in an embodiment of the present application is shown. The method 200 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. Figure 2 As shown, the method may include the following steps.

[0050] S210, the terminal determines that the first CSI report to be fed back currently includes target information, wherein the target information includes at least one of the following: delay information and frequency shift information.

[0051] In an embodiment of the present application, the terminal may determine that the first CSI report to be fed back includes target information, namely, at least one of delay information and frequency shift information, based on network signaling of a network-side device or based on measurement of a reference signal.

[0052] In an optional implementation, the terminal determines that the first channel state information CSI report to be fed back currently includes target information, including: the terminal determines, based on a first network signaling sent by a network side device, that the first CSI report includes the target information.

[0053] In the above implementation, the terminal can receive signaling sent by the network side device, which can be network signaling, for example, Radio Resource Control (RRC) signaling or Media Access Control Control Element (MAC-CE) or downlink control information (DCI), and determine that the first CSI report includes one or two types of information including delay information and frequency shift information. Subsequently, the first CSI report can be fed back to the network side device through uplink channel resources to facilitate synchronization or frequency alignment between the network side device and the terminal, so as to achieve better subsequent transmission performance or multi-transmission node (MTRP) transmission performance. Optionally, the terminal determines that the first CSI report includes one of the following based on the network signaling or DCI sent by the network side device: delay information, frequency shift information, or delay information and frequency shift information, that is, the network side device can configure the first CSI report fed back by the terminal through network signaling to include: delay information, frequency shift information, or delay information and frequency shift information, or can also indicate to the terminal through DCI that the first CSI report fed back by the terminal includes: delay information, frequency shift information, or delay information and frequency shift information. In this way, the network side device can flexibly adjust the content of the CSI report based on known information or channel reciprocity, and can avoid the feedback of some useless information.

[0054] In another optional implementation, the terminal determines that the first channel state information CSI report to be fed back currently includes target information, including: the terminal determines that the first CSI report includes the target information based on the measurement of the reference signal. In the above implementation, the terminal can receive the reference signal sent by the network side device, and determine that the first CSI report includes one or two types of information among the delay information and the frequency shift information. Further, optionally, the terminal can receive the reference signal sent by the network side device, and determine the reference signal associated with the delay information or the frequency shift information in the first CSI report, which can also be understood as the terminal determining which reference signals need to feedback the delay information or the frequency shift information.

[0055] In an optional implementation, the method may further include at least one of the following:

[0056] (1) The terminal determines, based on the second network signaling sent by the network side device, at least one first reference signal or at least one first reference signal set associated with the delay information, wherein the first reference signal set includes at least one first reference signal;

[0057] (2) the terminal determines, based on a third network signaling sent by a network-side device, at least one second reference signal or at least one second reference signal set associated with the frequency shift information, wherein the second reference signal set includes at least one second reference signal;

[0058] In an optional implementation of the embodiment of the present application, the network side device can control the content and size of the CSI report by indicating a reference signal or a reference signal set to the terminal, thereby avoiding the feedback of some useless information and reducing the network signaling overhead. It can be understood that the network side device can indicate part of the reference signals or reference signal sets among multiple reference signals or reference signal sets to obtain delay information or frequency shift information.

[0059] For determining the reference signal or reference signal set for obtaining delay information or frequency shift information, on the one hand, the terminal can determine the reference signal or reference signal set for obtaining delay information based on network signaling, or the terminal can also determine the reference signal or reference signal set for obtaining frequency shift information based on network signaling. In other words, the network side device can indicate that the reference signal or reference signal set associated with the delay information and the reference signal or reference signal set associated with the frequency shift information are not exactly the same. In this way, the network side device can flexibly and independently configure or indicate to the terminal the reference signal or reference signal set associated with the delay information and the reference signal or reference signal set associated with the frequency shift information. For example: a CSI report setting associates 4 reference signal sets for obtaining delay information and frequency shift information. Through network signaling, the terminal determines that the reference signal set used to obtain delay information is set 0 / 1 / 2, and the reference signal set for the user to obtain frequency shift information is set 1 / 2 / 3.

[0060] On the other hand, the terminal can determine the reference signal or reference signal set for obtaining the delay information and frequency shift information based on network signaling, that is, the delay information and frequency shift information share the same reference signal or reference signal set. For example: a CSI report setting is associated with 4 reference signal sets, and the network side device indicates to the terminal through network signaling that the reference signal set used to obtain the delay information and frequency shift information is set 0 / 1 / 2.

[0061] Through the above method, the network side device can flexibly control the amount of delay information or frequency shift information fed back by the terminal, and at the same time, it can also avoid the waste of resources caused by the terminal feeding back known information of the network side device.

[0062] (3) The terminal determines the accuracy of the delay information based on the fourth network signaling sent by the network side device;

[0063] (4) The terminal determines the accuracy of the frequency shift information based on the fifth network signaling sent by the network side device;

[0064] In an optional implementation method of an embodiment of the present application, the network side device can also indicate the granularity of the delay information or frequency shift information to the terminal through network signaling, that is, the network side device can control the accuracy or unit of the delay information and / or frequency shift information fed back by the terminal, avoiding high-precision feedback of large delays or frequency shifts, and low-precision feedback of small delays or frequency shifts, thereby effectively utilizing feedback resources and improving the effectiveness of feedback information.

[0065] A method for effectively utilizing feedback resources is that the accuracy is indicated to the network by the terminal, that is, the terminal can select a suitable time unit or frequency shift unit to feedback the delay information and / or frequency shift information according to the delay information and frequency shift information obtained by itself. In this way, the network side device can indicate a total feedback overhead to the terminal, and the terminal can feedback the delay information and / or frequency shift information with the highest accuracy without exceeding the total feedback overhead.

[0066] The accuracy of the delay information may refer to the length of a time unit, for example, 1 ms or 1 Ts (sampling period), etc. The accuracy of the frequency shift information may refer to the size of a frequency shift unit, for example, 1 Hz or 1000 Hz or 1 / N (N is fft size) or K times of pi (K is a rational number), etc.

[0067] Alternatively, the network side device may indicate multiple time units or frequency shift units to the terminal, and the terminal selects an appropriate time unit or frequency shift unit to feed back corresponding delay information or frequency shift information.

[0068] (5) The terminal determines, based on sixth network signaling sent by the network side device, the amount of delay information included in the first CSI report;

[0069] (6) determining, by the terminal, a maximum amount of delay information included in the first CSI report based on the seventh network signaling sent by the network side device;

[0070] (7) determining, by the terminal, the amount of frequency shift information included in the first CSI report based on the eighth network signaling sent by the network side device;

[0071] (8) The terminal determines a maximum amount of frequency shift information included in the first CSI report based on a ninth network signaling sent by a network side device.

[0072] It should be noted that the above-mentioned first to ninth network signalings may be one network signaling or multiple network signalings, and any two, three, four, five, six, seven, eight or nine of the first to ninth network signalings may be the same network signaling.

[0073] In an optional implementation of the embodiment of the present application, the network side device may also indicate to the terminal through network signaling the amount of delay information included in the CSI report, and the terminal may select a suitable reference signal or reference signal set based on the determined amount of delay information to feed back the associated delay information. In this case, some of the delay information fed back by the terminal may be an invalid value or a specific value, indicating that the delay information associated with the corresponding reference signal or reference signal group exceeds the available range.

[0074] Alternatively, the network side device may also indicate the maximum amount of delay information included in the CSI report to the terminal through network signaling, and the terminal selects an appropriate reference signal or a reference signal set to feedback its associated delay information. Further, the amount of delay information does not exceed the maximum amount. Optionally, the amount or maximum amount of frequency shift information included in the first CSI report may also be indicated to the terminal in a similar manner as described above. Optionally, the amount or maximum amount of frequency shift information-delay information pairs included in the first CSI report may also be indicated to the terminal in the manner of the above-mentioned network signaling. Through these methods, the quality of the delay information or frequency shift information in the CSI report can be effectively improved, and feedback of too many values ​​that exceed the processing range can be avoided.

[0075] In an optional implementation manner, when the first CSI report includes the frequency shift information, the frequency shift information included in the first CSI report includes one of the following:

[0076] (1) Frequency shifts associated with each second reference signal; that is, each frequency shift information included in the first CSI report is the frequency shift of each second reference signal. Optionally, the number of frequency shift information may be the number of second reference signals associated with the first CSI report, or the number of frequency shift information may be the number of second reference signals indicated by the network side device, or the number of frequency shift information may be the number of second reference signals selected by the terminal.

[0077] (2) Frequency shifts associated with each second reference signal set; that is, each frequency shift information included in the first CSI report is the frequency shift of each second reference signal set.

[0078] Optionally, when the first CSI report includes frequency shift information and the frequency shift information is for each second reference signal, the number of frequency shift information in the first CSI report may be the number of second reference signal sets associated with the first CSI report, or the number of frequency shift information may be the number of second reference signal sets indicated by the network side device, or the number of frequency shift information may be the number of second reference signal sets selected by the terminal.

[0079] Optionally, in the case where the frequency shift information included in the first CSI report is the frequency shift associated with each of the above-mentioned second reference signals or the frequency shift associated with each second reference signal set, the terminal determines or assumes that the reference signal associated with the first CSI report or the physical downlink channel associated with the first CSI report has no frequency shift, or the terminal determines that the reference signal associated with the first CSI report or the physical downlink channel associated with the first CSI report has no frequency shift offset. For example, when receiving the reference signal associated with the first CSI report or the physical downlink channel associated with the first CSI report, the terminal receives or demodulates the reference signal associated with the first CSI report or the physical downlink channel associated with the first CSI report, assuming that there is no frequency shift or frequency shift offset.

[0080] (3) The frequency shift offset of each second reference signal relative to the frequency shift associated with the reference reference signal; that is, in this optional implementation, each of the multiple frequency shift information included in the first CSI report is the frequency shift offset of a second reference signal relative to the reference reference signal. In the embodiment of the present application, the reference reference signal refers to a reference signal used as a reference, and the frequency shift of the reference reference signal is used as a reference, that is, the offset of the frequency shift of the reference reference signal is set to 0, and the frequency shift offsets of each other second reference signal relative to the frequency shift of the reference reference signal are obtained.

[0081] Optionally, when the first CSI report includes frequency shift information, and the frequency shift information is the offset of the frequency shift of each second reference signal relative to the frequency shift associated with the reference reference signal, the amount of frequency shift information in the first CSI report may be the total number of second reference signals associated with the first CSI report minus 1, or the total number of second reference signals indicated by the network side device minus 1, or the total number of second reference signals selected by the terminal minus 1. That is, the reference reference signal may be one of multiple second reference signals associated with the first CSI report, or one of multiple second reference signals indicated by the network side device, or one of multiple second reference signals selected by the terminal.

[0082] Optionally, when the first CSI report includes frequency shift information, and the frequency shift information is the offset of the frequency shift of each second reference signal relative to the frequency shift associated with the reference reference signal, the amount of frequency shift information in the first CSI report may also be the total number of second reference signals associated with the first CSI report minus N, or the total number of second reference signals indicated by the network side device minus N, or the total number of second reference signals selected by the terminal minus N, where N is an integer greater than 1. That is, the above-mentioned reference reference signal may be N of the multiple second reference signals associated with the first CSI report, for example: the first N or the last N, or N of the multiple second reference signals indicated by the network side device, or N of the multiple second reference signals selected or indicated by the terminal.

[0083] (4) The offset of the frequency shift of each second reference signal set relative to the frequency shift associated with the reference reference signal set. That is, in this optional implementation, each frequency shift information in the multiple frequency shift information included in the first CSI report is the offset of the frequency shift of a second reference signal set relative to the reference reference signal. In the embodiment of the present application, the reference reference signal set refers to a reference signal set used as a reference, and the frequency shift of the reference reference signal set is used as a reference, that is, the offset of the frequency shift of the reference reference signal set is set to 0, and the offset of the frequency shift of each other second reference signal set relative to the frequency shift of the reference reference signal set is obtained.

[0084] Optionally, when the first CSI report includes frequency shift information, and the frequency shift information is the offset of the frequency shift of each second reference signal set relative to the frequency shift associated with the reference reference signal set, the amount of frequency shift information in the first CSI report may be the total number of second reference signal sets associated with the first CSI report minus 1, or the total number of second reference signal sets indicated by the network side device minus 1, or the total number of second reference signal sets selected by the terminal minus 1. That is, the reference reference signal set may be one of multiple second reference signal sets associated with the first CSI report, or one of multiple second reference signal sets indicated by the network side device, or one of multiple second reference signal sets selected by the terminal.

[0085] Optionally, when the first CSI report includes frequency shift information, and the frequency shift information is the offset of the frequency shift of each second reference signal set relative to the frequency shift associated with the reference reference signal set, the amount of frequency shift information in the first CSI report may also be the total number of second reference signal sets associated with the first CSI report minus N, or the total number of second reference signal sets indicated by the network side device minus N, or the total number of second reference signal sets selected by the terminal minus N, where N is an integer greater than 1. That is, the above-mentioned reference reference signal set may be N of the multiple second reference signal sets associated with the first CSI report, for example: the first N or the last N, or N of the multiple second reference signal sets indicated by the network side device, or N of the multiple second reference signal sets selected or indicated by the terminal.

[0086] In an optional implementation of an embodiment of the present application, when the first CSI report includes frequency shift information, one frequency shift information may be a frequency shift associated with a second reference signal or a second reference signal set, or may be a frequency shift offset associated with two second reference signals or a second reference signal set. For example, for the MTRP scenario, it can be understood that for each TRP, the terminal feeds back a frequency shift, or the terminal determines a reference TRP and feeds back the frequency shift offset of other TRPs relative to the reference TRP.

[0087] In the case where a frequency shift information may be a frequency shift associated with a reference signal or a reference signal set, in one implementation, the number of frequency shift information may be the number of second reference signal sets or second reference signals associated with the first CSI report. In another implementation, the number of frequency shift information may be the number of second reference signal sets or the number of second reference signals indicated by the network side device. In yet another implementation, the number of frequency shift information may be the number of second reference signal sets or the number of second reference signals selected by the terminal.

[0088] Optionally, when the frequency shift information is a frequency shift, the reference signal or physical downlink channel associated with the first CSI report does not consider the frequency shift or the impact of the frequency shift. It can be understood that the terminal has fed back the frequency shift to the network side device, and the network side device compensates based on the frequency shift. For the impact of the subsequent frequency shift, the terminal can assume that there is no frequency shift to process. At this time, if there is a quasi-co-location information configuration, for the quasi-co-location information associated with the channel measurement reference signal or the physical downlink channel, the terminal does not refer to the frequency shift in the quasi-co-location information, or the terminal assumes that there is no frequency shift. Alternatively, at this time, the channel measurement reference signal or the physical downlink channel is not associated with the quasi-co-location information or is only associated with the spatial quasi-co-location information.

[0089] Similarly, when the CSI report includes delay information, one delay information may be a delay associated with a first reference signal or a first reference signal set, or a delay offset associated with two first reference signals or a first reference signal set. For example, for the MTRP scenario, it can be understood that for each TRP, the terminal feeds back a delay, or the terminal determines a reference TRP and feeds back the delay offset of other TRPs relative to the reference TRP.

[0090] For the case where a delay information may be a delay associated with a first reference signal or a first reference signal set, the amount of delay information is the first reference signal set or the number of first reference signals associated with the first CSI report, or the amount of delay information is the number of first reference signal sets or the number of first reference signals indicated by the network side device, or the amount of delay information is the number of first reference signal sets or the number of first reference signals selected by the terminal.

[0091] For the case where a delay information may be an offset of the delay; that is, in this optional implementation, each of the multiple delay information included in the first CSI report is an offset of the delay of one second reference signal or a second reference signal set relative to the reference reference signal or a reference reference signal set. Optionally, the number of delay information in the first CSI report may be the total number of first reference signals or first reference signal sets associated with the first CSI report minus 1, or the total number of first reference signals or first reference signal sets indicated by the network side device minus 1, or the total number of first reference signals or first reference signal sets selected by the terminal minus 1. That is, the above-mentioned reference reference signal or reference reference signal set may be one of the multiple first reference signals or first reference signal sets associated with the first CSI report, or one of the multiple first reference signals or first reference signal sets indicated by the network side device, or one of the multiple first reference signals or first reference signal sets selected by the terminal. Optionally, the amount of frequency shift information in the first CSI report may be the total number of first reference signals or first reference signal sets associated with the first CSI report minus N, or the total number of first reference signals or first reference signal sets indicated by the network side device minus N, or the total number of first reference signals or first reference signal sets selected by the terminal minus N, where N is an integer greater than 1. That is, the above-mentioned reference reference signal or reference reference signal set may be N of the multiple first reference signals or first reference signal sets associated with the first CSI report, for example: the first N or the last N, or N of the multiple first reference signals or first reference signal sets indicated by the network side device, or N of the multiple first reference signals or first reference signal sets selected or indicated by the terminal.

[0092] Optionally, when the delay information is a delay, the reference signal or physical downlink channel associated with the first CSI report does not consider the delay or the impact of the delay. It can be understood that the terminal feeds back the delay to the network side device, and the network side device compensates based on the delay. For the impact of subsequent delays, the terminal can assume that there is no delay to process. At this time, if there is quasi-co-location information configuration, for the channel measurement reference signal or the quasi-co-location information associated with the physical downlink channel, the terminal does not refer to the actual delay in the quasi-co-location information, or the terminal assumes that there is no delay. Alternatively, at this time, the channel measurement reference signal or the physical downlink channel is not associated with the quasi-co-location information or is only associated with the spatial quasi-co-location information.

[0093] In an optional implementation, the terminal may determine, based on the tenth network signaling sent by the network side device, that the frequency shift information includes the frequency shift or the offset of the frequency shift, or determine that the delay information includes the delay or the offset of the delay. It can be understood that the network may configure, through high-level signaling, whether the terminal feeds back the frequency shift or the delay, or the frequency shift offset or the delay offset.

[0094] S212: The terminal obtains the target information based on the reference signal associated with the first CSI report.

[0095] In an embodiment of the present application, the terminal may obtain target information based on the reference signal associated with the first CSI report. For example, the terminal may obtain delay information based on at least one first reference signal or at least one first reference signal set associated with the first CSI report, or the terminal may obtain frequency shift information based on at least one second reference signal or at least one second reference signal set associated with the first CSI report. Among them, the at least one first reference signal or at least one first reference signal set or at least one second reference signal or at least one second reference signal set associated with the first CSI report may be determined according to the reference signal or reference signal set configured by the network side device, or may be indicated by the network side device through network signaling, or may be selected by the terminal according to the measurement result, which may be determined according to the actual situation.

[0096] It should be noted that the at least one first reference signal and the at least one second reference signal may be one reference signal or multiple reference signals, or the at least one first reference signal set and the at least one second reference signal set may be one reference signal set or multiple reference signal sets.

[0097] In an optional implementation, when the terminal obtains the target information in the first CSI report, the number of CSI processing units (CSI processing units, CPUs) associated with the first CSI report is related to at least one of the following:

[0098] (1) the number of reference signal sets associated with the first CSI report;

[0099] (2) The target information included in the first CSI report.

[0100] That is to say, for the calculation of the first CSI report, the number of CPUs associated with the first CSI report is related to the number of reference signal sets associated with the first CSI report; or, for the calculation of the first CSI report, the number of CPUs associated with the first CSI report is related to whether the report content associated with the first CSI report is one or two of the delay information or frequency shift information.

[0101] In another optional implementation, for the calculation of the first CSI report, the number of CPUs associated with the first CSI report is related to the number of at least one first reference signal or at least one first reference signal set associated with the first CSI report; or, for the calculation of the first CSI report, the number of CPUs associated with the first CSI report is related to the number of at least one second reference signal or at least one second reference signal set associated with the first CSI report.

[0102] In an optional implementation, when the target information included in the first CSI report is an offset of a time delay or a frequency shift, the method may further include: the terminal carries target indication information in the first CSI report, wherein the target indication information is used to indicate a reference signal or a reference signal set to which the target information refers.

[0103] In the above optional implementation, when the frequency shift information included in the first CSI report is the frequency shift offset, or when the delay information included in the first CSI report is the delay offset, the reference frequency shift or reference delay of the offset may be indicated by the terminal. Optionally, the terminal may indicate to the network side device in the first CSI report that a certain reference signal or a reference signal set is a reference for the frequency shift offset and the delay offset; or, the terminal may indicate to the network side device in the first CSI report that a certain reference signal or a reference signal set is a reference for the frequency shift offset; or, the terminal may indicate to the network side device in the first CSI report that a certain reference signal or a reference signal set is a reference for the delay offset.

[0104] In an optional implementation, after S212, the method may further include: the terminal feeds back the first CSI report, wherein the feedback priority of the first CSI report is higher than that of the second CSI report, and the second CSI report includes multi-transmission node MTRP CSI. The feedback priority of the first CSI report is higher than that of the second CSI report, indicating that when the first CSI report and the second CSI report conflict, or the first CSI report and the second CSI report are multiplexed into the same channel resource (e.g., PUSCH / PUCCH), the first CSI report is processed or fed back preferentially.

[0105] Optionally, it may be determined that the feedback priority of the first CSI report is higher than that of the second CSI report when the first CSI report and the second CSI report satisfy at least one of the following conditions:

[0106] (1) The first CSI report and the second CSI report are associated with the same CSI report type, where the CSI report type includes one of the following: periodic CSI report, semi-continuous CSI report, and aperiodic CSI report;

[0107] (2) The first CSI report and the second CSI report are associated with the same channel type, wherein the channel type includes one of the following: a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) and a physical uplink control channel (Physical Uplink Control Channel, PUCCH);

[0108] (3) The first CSI report and the second CSI report are associated with the same serving cell.

[0109] (4) The first CSI report and the second CSI report have a target association relationship, wherein the target association relationship includes at least one of the following:

[0110] a) the quasi-co-located reference signal of the reference signal present in the reference signal associated with the second CSI report is the reference signal associated with the first CSI report;

[0111] b) The association relationship between the second CSI report and the first CSI report indicated by the eleventh network signaling associated with the second CSI report, the eleventh network signaling comprising one of the following: CSI report setting signaling, serving cell configuration signaling; for example, the CSI report setting (CSI-ReportConfig) command associated with the second CSI report establishes a target association relationship between the first CSI report and the second CSI report, or the serving cell configuration (ServingCellConfig) signaling associated with the second CSI report establishes a target association relationship between the first CSI report and the second CSI report.

[0112] c) an association relationship between the second CSI report and the first CSI report established through a physical cell identifier.

[0113] d) an association relationship between the second CSI report and the first CSI report established by measuring the bandwidth part.

[0114] In an actual system, there may be a situation where multiple CSI reports conflict or multiple CSI reports are multiplexed to one channel resource (for example, multiplexed to one PUSCH). Therefore, the priority order of multiple CSI reports can be agreed upon, and the CSI report with a higher priority will be processed preferentially or mapped to the channel resource for feedback. Based on this, there may be a situation where at least one first CSI report and at least one second CSI report conflict or are multiplexed, which can also be understood as a situation where a CSI report carrying delay information and / or frequency shift information and an MTRP CSI report (the MTRP CSI report is usually a CSI report associated with joint measurement of multiple reference signals) conflict or are multiplexed.

[0115] In one implementation of an embodiment of the present application, the priority of the first CSI report carrying delay information or frequency shift information is higher than that of the second CSI report (i.e., MTRP CSI report), because the delay information or frequency shift information is more important for helping the network side device to achieve higher quality MTRP transmission, and in addition, the feedback of delay information or frequency shift information may not be as frequent as the feedback of the MTRPCSI report. The above-mentioned MTRP CSI report is a CSI report that includes MTRP CSI (for example: CJT CSI or NCJT CSI or dynamic transmission point selection (Dynamic Point Selection, DPS) CSI, etc.) in the CSI report.

[0116] Further, optionally, more detailed situations can be established to help the terminal more effectively and reasonably determine the priority of a CSI report carrying delay information or frequency shift information. That is, when at least one of the following situations is met, the priority associated with the first CSI report is higher than that of the second CSI report. The situations include:

[0117] i. The first CSI report carrying delay information or frequency shift information is associated with the same CSI report type (periodic CSI report or semi-continuous CSI report or aperiodic CSI report) as the MTRP CSI report;

[0118] ii. The first CSI report carrying delay information or frequency shift information is associated with the same channel type (PUSCH / PUCCH) as the MTRP CSI report;

[0119] iii. The first CSI report carrying delay information or frequency shift information is associated with the same serving cell as the MTRP CSI report;

[0120] iv. The first CSI report carrying delay information or frequency shift information is associated with the MTRP CSI report;

[0121] In particular, the association between the first CSI report carrying the delay information or the frequency shift information and the MTRP CSI report may be established in at least one of the following ways:

[0122] a) A quasi-co-located reference signal of a reference signal in the reference signal associated with the MTRP CSI report is a reference signal associated with the CSI report carrying the delay information and / or frequency shift information;

[0123] b) Establishing an association relationship through network signaling associated with the MTRP CSI report (CSI report setting CSI-ReportConfig); for example: there are parameters in the CSI-ReportConfig setting associated with the first CSI report carrying delay information or frequency shift information.

[0124] c) Establishing an association relationship through network signaling associated with the MTRP CSI report (serving cell configuration ServingCellConfig); for example: the same network signaling associated with the MTRP CSI report and the first CSI report carrying the delay information or frequency shift information, such as ServingCellConfig or CSI-MeasConfig;

[0125] d) Establishing an association relationship through a physical cell ID; for example, the MTRP CSI report and the first CSI report carrying the delay information or frequency shift information are associated with the same physical cell ID;

[0126] e) Establishing an association relationship through the measurement bandwidth part; for example: the MTRP CSI report and the first CSI report carrying the delay information or frequency shift information are associated with the same measurement bandwidth.

[0127] Through the above method, the priority of the MTRP CSI report and the first CSI report carrying delay information or frequency shift information can be clarified to avoid inconsistent understanding of the priority of the CSI report between the terminal and the network side equipment, which leads to errors in the network side equipment parsing the CSI report. At the same time, more important CSI information can be fed back to the network side equipment as much as possible to ensure the stability of transmission.

[0128] In an optional implementation, the method may further include: in a first case, the terminal determines to feed back the first CSI report and performs a first target operation.

[0129] The first situation may include at least one of the following:

[0130] (1) The most recent transmission timing of all reference signals associated with the first CSI report is later than the CSI reference resource associated with the second CSI report and earlier than the feedback time slot or feedback symbol associated with the second CSI report, and the second CSI report includes MTRP CSI;

[0131] Optionally, the CSI reference resource may be an uplink time slot, or may be associated with a downlink time slot, or may be associated with a symbol of an uplink time slot, or may be associated with a symbol of a downlink time slot. The terminal obtains the CSI in the second CSI report based on the CSI reference resource.

[0132] Optionally, the feedback time slot or feedback symbol may be the first time slot or the first symbol of all time slots or symbols associated with the second CSI report, or may be a time slot or a symbol agreed upon by the protocol.

[0133] (2) The most recent transmission timing of any reference signal associated with the first CSI report is later than the CSI reference resource associated with the second CSI report and earlier than the feedback time slot or feedback symbol associated with the second CSI report;

[0134] (3) The feedback time slot or feedback symbol associated with the first CSI report is later than the CSI reference resource associated with the second CSI report, and earlier than the feedback time slot or feedback symbol associated with the second CSI report.

[0135] The first target operation includes at least one of the following:

[0136] a) not feeding back the second CSI report;

[0137] b) Feedback partial content of the second CSI report; for example, only feed back the CSI report part 1, i.e., Part 1, of the second CSI report, or only feed back the STRP CSI in the second CSI report, without feeding back the MTRP CSI in the CSI report.

[0138] c) indicating in the first CSI report whether to feed back the second CSI report;

[0139] d) indicating in the first CSI report whether to feed back part of the content of the second CSI report.

[0140] For example, the terminal may determine whether the above-mentioned first situation is met after obtaining the configuration of the reference signal associated with the first CSI report, or after obtaining the reference signal associated with the first CSI report, or after obtaining the target information based on the reference signal associated with the first CSI report. If so, the terminal determines to feed back the first CSI report, the terminal does not feed back the second CSI report, or the terminal only feeds back part of the content of the second CSI report, or the terminal indicates in the first CSI report whether to feed back the second CSI report or part of the content of the second CSI report.

[0141] Among them, the above-mentioned most recent transmission opportunity includes but is not limited to one of the following: earlier than the most recent transmission opportunity of the reference signal of the CSI reference resource associated with the first CSI report, earlier than the most recent transmission opportunity of the reference signal of the feedback time slot or feedback symbol associated with the first CSI report, and earlier than the most recent transmission opportunity of the reference signal of the protocol-agreed time slot or symbol associated with the first CSI report.

[0142] Since the CSI of delay information or frequency shift information may affect the calculation of MTRP CSI, there are some cases where the CSI feedback of delay information or frequency shift information may cause the MTRP CSI to fail or be inaccurate, resulting in performance loss. Figure 3 In the present invention, when the reference signal of CSI used to obtain the delay information or frequency shift information appears between the CSI reference resource and the CSI feedback associated with the MTRP CSI, the MTRP CSI may be inaccurate or have a large error, because the MTRP CSI is calculated based on the delay information and / or frequency shift information previously measured by the CSI reference resource, and is not calculated based on the measurement results of the latest measured delay information and / or frequency shift information.

[0143] The above situations may include at least one of the following:

[0144] (1) The most recent transmission timing of all reference signals associated with the first CSI report associated with the delay information or frequency shift information is later than the CSI reference resource associated with the MTRP CSI report and earlier than the feedback time slot or feedback symbol associated with the MTRP CSI report, such as Figure 3 As shown;

[0145] For example, when the reception time of all reference signals used by the terminal to obtain the first CSI report of the delay information or frequency shift information is later than the CSI reference resource associated with the MTRP CSI report and earlier than the feedback time slot or feedback symbol associated with the MTRP CSI report, the CSI feedback of the delay information and / or frequency shift information may cause the MTRP CSI to be invalid or inaccurate.

[0146] (2) The most recent transmission timing of any reference signal associated with the first CSI report associated with the delay information or frequency shift information is later than the CSI reference resource associated with the MTRP CSI report and earlier than the feedback time slot or feedback symbol associated with the MTRP CSI report;

[0147] For example, when the reception time of any one or more reference signals used by the terminal to obtain the first CSI report of the delay information or frequency shift information is later than the CSI reference resource associated with the MTRP CSI report and earlier than the feedback time slot or feedback symbol associated with the MTRP CSI report, the first CSI report feedback of the delay information or frequency shift information may cause the MTRP CSI to be invalid or inaccurate.

[0148] (3) The feedback time slot or feedback symbol associated with the first CSI report associated with the delay information or frequency shift information is later than the CSI reference resource associated with the second CSI report and earlier than the feedback time slot or feedback symbol associated with the second CSI report;

[0149] For example, when the feedback time slot or feedback symbol associated with the first CSI report of the delay information or frequency shift information is later than the CSI reference resource associated with the MTRP CSI report and earlier than the feedback time slot or feedback symbol associated with the MTRP CSI report, the first CSI report feedback of the delay information or frequency shift information may cause the MTRP CSI to be invalid or inaccurate.

[0150] The most recent transmission opportunity may be the most recent transmission opportunity of the reference signal of the CSI reference resource associated with the CSI report earlier than the delay information and / or frequency shift information, or the most recent transmission opportunity of the reference signal of the feedback time slot or feedback symbol associated with the CSI report earlier than the CSI report. The CSI reference resource may be an uplink time slot, or may be associated with a downlink time slot, or may be associated with a symbol of an uplink time slot, or may be associated with a symbol of a downlink time slot. The terminal acquires CSI based on the CSI reference resource. The feedback time slot or feedback symbol may be the first time slot or the first symbol of all time slots or symbols associated with the MTRP CSI report, or may be a time slot or a symbol agreed upon by the protocol.

[0151] For invalid or inaccurate MTRP CSI or MTRP CSI report, the terminal may handle the invalid or inaccurate MTRP CSI or MTRP CSI report in at least one of the following ways:

[0152] (1) The terminal does not feed back the MTRP CSI report;

[0153] (2) The terminal only feeds back part of the MTRP CSI report, for example, only feeds back the CSI report part 1 (Part 1) of the MTRP CSI report, or only feeds back the STRP CSI in the MTRP CSI report, but does not feed back the MTRP CSI in the CSI report;

[0154] (3) The terminal indicates whether to feed back the MTRP CSI report in the first CSI report carrying the delay information or frequency shift information. For example, if the terminal finds that the MTRP CSI report is inaccurate or invalid, it may indicate that the MTRP CSI report is not fed back later in the first CSI report carrying the delay information or frequency shift information. If the terminal finds that the MTRP CSI report is accurate, it may indicate that the MTRP CSI report is fed back later in the first CSI report carrying the delay information or frequency shift information.

[0155] (4) The terminal indicates in the first CSI report carrying the delay information or frequency shift information whether to feed back part of the content of the MTRP CSI report. For example, if the terminal finds that the MTRP CSI report is inaccurate or invalid, it can indicate in the first CSI report carrying the delay information or frequency shift information that the CSI report fed back later only includes CSI report Part 1 or the CSI report does not include MTRP CSI but only includes STRP CSI.

[0156] Through the above-mentioned method, invalid or inaccurate MTRP CSI feedback or feedback of MTRP CSI report can be avoided or reduced, thereby reducing the complexity of calculating MTRP CSI by the terminal and avoiding the problem of transmission performance degradation caused by feedback of invalid information.

[0157] In an optional implementation, the method may further include: in a second case, the terminal determines to feed back a second CSI report and performs a second target operation, wherein the second CSI report includes MTRP CSI.

[0158] The second situation may include at least one of the following:

[0159] (1) The most recent transmission timing of all reference signals associated with the second CSI report is later than the CSI reference resource associated with the first CSI report and earlier than the feedback time slot or feedback symbol associated with the first CSI report;

[0160] (2) The most recent transmission timing of all reference signals associated with the MTRP CSI associated with the second CSI report is later than the CSI reference resource associated with the first CSI report and earlier than the feedback time slot or feedback symbol associated with the first CSI report; that is, the most recent transmission timing of all reference signals associated with the MTRP CSI associated with the second CSI report is later than the CSI reference resource associated with the first CSI report and earlier than the feedback time slot or feedback symbol associated with the first CSI report;

[0161] (3) The most recent transmission timing of any reference signal associated with the second CSI report is later than the CSI reference resource associated with the first CSI report and earlier than the feedback time slot or feedback symbol associated with the first CSI report;

[0162] (4) The most recent transmission timing of any reference signal associated with the MTRP CSI associated with the second CSI report is later than the CSI reference resource associated with the first CSI report and earlier than the feedback time slot or feedback symbol associated with the first CSI report; that is, the most recent transmission timing of any reference signal associated with the MTRP CSI associated with the second CSI report is later than the CSI reference resource associated with the first CSI report and earlier than the feedback time slot or feedback symbol associated with the first CSI report;

[0163] (5) The feedback time slot or feedback symbol associated with the second CSI report is later than the CSI reference resource associated with the first CSI report, and earlier than the feedback time slot or feedback symbol associated with the first CSI report.

[0164] The second target operation includes at least one of the following:

[0165] a) not feeding back the first CSI report;

[0166] b) Feedback part of the content of the first CSI report; for example, only feed back the CSI report part 1, i.e., Part 1, of the first CSI report; or, only feed back the frequency offset information in the first CSI report, without feeding back the delay information in the first CSI report; or, only feed back the delay information in the first CSI report, without feeding back the frequency offset information in the first CSI report.

[0167] c) indicating in the second CSI report whether to feed back the first CSI report;

[0168] d) indicating in the second CSI report whether to feed back part of the content of the first CSI report.

[0169] For example, the terminal may determine whether the above-mentioned second situation is met after obtaining the configuration of the reference signal associated with the first CSI report, or after obtaining the reference signal associated with the first CSI report, or after obtaining the target information based on the reference signal associated with the first CSI report. If so, the terminal determines to feed back the second CSI report, the terminal does not feed back the first CSI report, or the terminal only feeds back part of the content of the first CSI report, or the terminal indicates in the second CSI report whether to feed back the first CSI report or part of the content of the first CSI report.

[0170] Among them, the above-mentioned most recent transmission opportunity includes but is not limited to one of the following: earlier than the most recent transmission opportunity of the reference signal of the CSI reference resource associated with the second CSI report, earlier than the most recent transmission opportunity of the reference signal of the feedback time slot or feedback symbol associated with the second CSI report, and earlier than the most recent transmission opportunity of the reference signal of the protocol-agreed time slot or symbol associated with the second CSI report.

[0171] In an actual system, the MTRP CSI may affect the acquisition and feedback of the CSI of the delay information or frequency shift information. Therefore, in some cases, the calculation and feedback of the MTRP CSI makes it unnecessary to calculate and feedback the CSI of the delay information or frequency shift information. Figure 4 In the present invention, when the feedback of MTRP CSI appears between the CSI reference resource associated with the first CSI report carrying the delay information and the frequency shift information and the CSI feedback, since the MTRP CSI carries the delay information, in order to avoid redundant delay information feedback, the delay information is not fed back in the first CSI report carrying the delay information and the frequency shift information.

[0172] The above situation may include at least one of the following situations.

[0173] i. The most recent transmission opportunity of all reference signals associated with the MTRP CSI report is later than the CSI reference resource associated with the first CSI report carrying the delay information or frequency shift information and earlier than the feedback time slot or feedback symbol associated with the CSI report carrying the delay information and / or frequency shift information;

[0174] ii. The most recent transmission opportunity of any reference signal associated with the MTRP CSI report is later than the CSI reference resource associated with the first CSI report carrying the delay information or frequency shift information and earlier than the feedback time slot or feedback symbol associated with the CSI report carrying the delay information and / or frequency shift information;

[0175] iii. The feedback time slot or feedback symbol associated with the MTRP CSI report is later than the CSI reference resource associated with the first CSI report carrying the delay information or frequency shift information and earlier than the feedback time slot or feedback symbol associated with the CSI report carrying the delay information and / or frequency shift information;

[0176] The most recent transmission opportunity may be a most recent transmission opportunity of a reference signal of a CSI reference resource associated with the MTRP CSI report, or a most recent transmission opportunity of a reference signal of a feedback slot or feedback symbol associated with the MTRP CSI report.

[0177] The CSI of the delay information or frequency shift information does not need to be calculated and fed back, or only part of the content is fed back, including at least one of the following situations:

[0178] 1. The terminal does not feed back the first CSI report carrying the delay information or frequency shift information. For example, when the MTRP CSI includes delay information, and the first CSI report is a CSI report carrying delay information, if there is an MTRP CSI feedback before the feedback moment of the first CSI report carrying the delay information and after the CSI reference resource associated with the first CSI report carrying the delay information, at this time, the CSI report carrying the delay information is not fed back or one feedback is skipped.

[0179] 2. The terminal only feeds back part of the content of the first CSI report carrying the delay information or frequency shift information. Optionally, the part of the content is part of the delay information, or part of the frequency shift information, or the delay information, or the frequency shift information, or part 1 of the CSI report. For example, when the MTRP CSI includes delay information, and the first CSI report is a CSI report carrying delay information and frequency shift information, if there is an MTRPCSI feedback before the feedback moment of the CSI report carrying the delay information and frequency shift information and after the CSI reference resource associated with the CSI report carrying the delay information and frequency shift information, only the CSI report part 1, i.e., Part 1, of the first CSI report carrying the delay information and frequency shift information is fed back, or only the frequency domain information in the first CSI report carrying the delay information and frequency shift information is fed back;

[0180] 3. The terminal indicates in the MTRP CSI report whether to feed back the first CSI report carrying the delay information and / or frequency shift information. For example, if the terminal finds that the MTRP CSI report can accurately carry the delay information or frequency shift information, it can indicate in the MTRP CSI report that there is no first CSI report carrying the delay information or frequency shift information, that is, the first CSI report carrying the delay information or frequency shift information skips feedback once.

[0181] 4. The terminal indicates in the MTRP CSI report whether to feed back part of the content of the first CSI report carrying the delay information or frequency shift information. Optionally, the part is part of the delay information, or part of the frequency shift information, or the delay information, or the frequency shift information, or CSI report part 1. For example, if the terminal finds that the MTRP CSI report can accurately carry the delay information, it can indicate in the MTRP CSI report that the first CSI report carrying the delay information and frequency shift information only feeds back the frequency shift information. Alternatively, it can indicate in the MTRP CSI report that the first CSI report carrying the delay information and frequency shift information only feeds back the CSI report part 1.

[0182] By the above method, repeated feedback of delay information or frequency shift information can be avoided or reduced, thereby reducing terminal calculation complexity. Further, the network side device can reduce the feedback resources occupied by the CSI report carrying delay information or frequency shift information, thereby improving resource utilization.

[0183] In an optional implementation manner, the method further includes: the terminal obtains the second CSI report, wherein the second CSI report includes MTRP CSI.

[0184] Optionally, the PMI associated with the second CSI report is calculated by referring to a target symbol associated with the CSI reference resource associated with the second CSI report, wherein the target symbol includes one of: the first symbol associated with the CSI reference resource, the last symbol associated with the CSI reference resource, and a symbol agreed upon by protocol among multiple symbols associated with the CSI reference resource.

[0185] Optionally, when the first CSI report is associated with the second CSI report (for example, having the above-mentioned target association relationship), the calculation of the PMI associated with the second CSI report can be calculated by referring to the target symbol associated with the CSI reference resource associated with the second CSI report. The target symbol may be the first symbol or the last symbol of multiple symbols associated with the CSI reference resource or a symbol agreed upon by the protocol. That is to say, the PMI associated with the second CSI report can be calculated based on the CSI reference resource, or calculated on the CSI reference resource, or compensated to the CSI reference resource for calculation, or aligned to the CSI reference resource for calculation, that is, the terminal compensates or adjusts the channel obtained at the measurement timing of the reference signal associated with the second CSI report, aligns the channels of all reference signals to the CSI reference resource, and further obtains the CSI.

[0186] Optionally, the terminal may also determine, according to a twelfth network signaling or a default rule or a protocol agreement, that the PMI associated with the second CSI report is calculated by a target symbol associated with a reference CSI reference resource associated with the second CSI report. For example, the terminal determines, through network high-layer signaling configuration, whether to calculate the PMI by a target symbol associated with a reference CSI reference resource associated with the second CSI report, or by default, when the first CSI report associated with the second CSI report includes frequency shift information, the terminal calculates the PMI by a target symbol associated with a reference CSI reference resource associated with the second CSI report, or by default, when the second CSI report is associated with the first CSI report, the terminal calculates the PMI by a target symbol associated with a reference CSI reference resource associated with the second CSI report.

[0187] Optionally, when the CSI reference resource associated with the second CSI report is associated with a time slot, the PMI associated with the second CSI report is calculated by referring to the time slot associated with the CSI reference resource associated with the second CSI report.

[0188] In an embodiment of the present application, for the acquisition of an MTRP CSI report (the second CSI report), reference can be made to the at least one first CSI report associated with it that includes delay information or frequency shift information. A possible reference method is that the terminal obtains the MTRP CSI report based on a specific time, and the specific time is a time agreed upon by the transceiver. It can be understood that the impact of the delay or frequency shift before the specific time is processed by the terminal, and the impact of the delay or frequency shift after the specific time until the data is transmitted is processed by the network. In this way, the performance impact caused by repeated processing by the network and the terminal can be effectively avoided, or the performance impact caused by the situation where neither the network nor the terminal has processed it can be avoided.

[0189] For a specific time, one possible method is CSI reference resources, which can be a downlink time slot or an uplink time slot, and can be obtained through network indication or protocol agreement or protocol agreed rules or terminal indication. That is, the calculation of the PMI associated with the MTRP CSI report needs to refer to the CSI reference resource. For example, the terminal measures the channel at the time of transmission of the CSI Reference Signal (CSI-RS), compensates the effect of frequency shift on the CSI reference resource, and then calculates the corresponding MTRP PMI and feeds it back to the network.

[0190] For a specific time, another possible method is a specific symbol of the CSI reference resource, and the specific symbol may be the first symbol or the last symbol of the CSI reference resource or a symbol agreed upon by the protocol or the first downlink symbol or the first uplink symbol or the last downlink symbol or the last uplink symbol or the first non-uplink non-downlink symbol. For example, the terminal measures the channel at the CSI-RS transmission time, compensates the effect of the frequency shift to the first symbol of the CSI reference resource, and then calculates the corresponding MTRP PMI and feeds it back to the network.

[0191] Optionally, for a specific time, the terminal can determine, based on network signaling or default rules, whether the calculation of the PMI associated with the second CSI report refers to the first symbol or the last symbol of the CSI reference resource, or a symbol agreed upon by the protocol, or the time slot associated with the CSI reference resource. For example, the network indicates that the calculation is based on the time slot or based on the first symbol. For another example, the protocol agreed rules, for CSI reference resources that include both uplink symbols and downlink symbols, the calculation is based on the first downlink symbol, and for CSI reference resources that include uplink symbols and non-uplink and non-downlink symbols, the calculation is based on the first non-uplink and non-downlink symbol.

[0192] In an optional implementation, before the terminal acquires the second CSI report, in a case where the second CSI report is associated with at least one of the first CSI reports, the terminal may determine one of the following based on a thirteenth network signaling of a network side device:

[0193] (1) The terminal obtains the second CSI report based on target feedback of at least one of the first CSI reports associated with the second CSI report, wherein the target feedback includes one of the following that is no later than the CSI reference resource associated with the second CSI report: the most recent feedback, any feedback, and feedback agreed upon by the protocol; optionally, the most recent feedback is no later than feedback of the CSI reference resource associated with the second CSI report, and the any feedback or the feedback agreed upon by the protocol may be no later than feedback of the CSI reference resource associated with the second CSI report.

[0194] (2) The terminal does not obtain the second CSI report based on any feedback of at least one first CSI report associated with the second CSI report. That is, when the terminal obtains the second CSI report, the feedback content of the at least one first CSI report is not considered.

[0195] In an optional implementation manner of an embodiment of the present application, for the acquisition of an MTRP CSI report (the second CSI report), when the MTRP CSI report is associated with the feedback of the at least one first CSI report including delay information or frequency shift information, if the feedback of the first CSI report including the delay information or the frequency shift information is a periodic or semi-continuous CSI feedback, the network may instruct the terminal through signaling according to or with reference to which (or not with reference to) the feedback of the first CSI report to obtain the MTRP CSI report, including at least one of the following:

[0196] 1. The terminal obtains the MTRP CSI report based on the latest feedback of the at least one first CSI report including the delay information or the frequency shift information associated with the MTRP CSI report;

[0197] 2. The terminal obtains the MTRP CSI report based on a feedback of the at least one first CSI report including the delay information or the frequency shift information associated with the MTRP CSI report

[0198] 3. The terminal does not obtain the MTRP CSI report based on any feedback of the at least one first CSI report including delay information or frequency shift information associated with the MTRP CSI report, that is, when the terminal obtains the MTRP CSI report, the feedback content of the at least one first CSI report is not considered;

[0199] Optionally, the most recent feedback is no later than the feedback of the CSI reference resource associated with the second CSI report; the feedback may be any time, or a feedback agreed upon in the protocol.

[0200] In this way, the network side device can control whether the terminal obtains the MTRP CSI report based on the feedback of the first CSI report of the latest delay information or frequency shift information, thereby improving the accuracy of the MTRP CSI report. Or when the network side device does not receive the feedback of the first CSI report of the latest delay information or frequency shift information, it instructs the terminal to obtain the MTRP CSI report based on the previous feedback, or the MTRP CSI report is obtained without reference to the feedback of the first CSI report of the delay information or frequency shift information. This avoids the impact of inaccurate MTRP CSI reports and improves the flexibility of network side device configuration.

[0201] In an optional implementation, when the second CSI report is associated with at least one of the first CSI reports, the terminal may obtain the second CSI report according to at least one of the following:

[0202] (1) The terminal obtains a target value based on a default rule or a fourteenth network signaling sent by a network side device, and obtains the second CSI report based on the target value, wherein the target value includes one of the following: a frequency shift value, a delay value, a frequency shift offset, and a delay offset;

[0203] (2) The terminal determines, based on the fifteenth network signaling sent by the network side device, to obtain the second CSI report by referring to all or part of the target information of at least one of the first CSI reports.

[0204] In an optional implementation of an embodiment of the present application, for the acquisition of an MTRP CSI report (the second CSI report), when the MTRP CSI report is associated with the feedback of the at least one first CSI report including delay information or frequency shift information, and the at least one first CSI report including delay information or frequency shift information is associated with multiple delay information or frequency shift information, at this time, the network side device can select at least part of the delay information / or frequency shift information from the multiple delay information or frequency shift information through signaling or the transceiver through default rules for obtaining the MTRP CSI report. In this way, the implementation complexity of the network side device can be simplified, and some delay information or frequency shift information can be handed over to the terminal for processing.

[0205] The network side device can select at least part of the delay information or frequency shift information from the multiple delay information or frequency shift information through signaling or the transceiver through default rules to obtain the MTRP CSI report, including at least one of the following implementation methods.

[0206] Implementation method 1: The terminal obtains a first value according to the network signaling indicated by the network side device, and the terminal obtains the MTRP CSI report based on the first value, and the first value can be a frequency shift value or a delay value or a frequency shift offset value or a delay offset value. For at least part of the delay information or frequency shift information of the multiple delay information or frequency shift information greater than or equal to the first value, the terminal needs to consider it when obtaining the MTRP CSI report. In other words, for at least part of the delay information or frequency shift information of the multiple delay information or frequency shift information less than or equal to the first value, the terminal does not refer to these delay information or frequency shift information when obtaining the MTRP CSI report.

[0207] Implementation method 2: The terminal determines a second value based on a default rule, and the terminal obtains the MTRP CSI report based on the second value, where the second value is a frequency shift value or a delay value or a frequency shift offset value or a delay offset value. The default rule may determine the second value for the terminal through the bandwidth or carrier spacing associated with the MTRP CSI report. Alternatively, the default rule may be for the terminal to obtain the second value according to the measurement configuration or report configuration associated with the MTRP CSI report. For at least part of the delay information or frequency shift information of the multiple delay information or frequency shift information greater than or equal to the second value, the terminal needs to consider it when obtaining the MTRP CSI report. In other words, for at least part of the delay information or frequency shift information of the multiple delay information or frequency shift information less than or equal to the second value, the terminal does not refer to these delay information or frequency shift information when obtaining the MTRP CSI report.

[0208] Further, when the terminal obtains the second CSI report, the network side device may indicate through high-layer signaling whether to refer to all the delay information or frequency shift information of the at least one CSI report, or to refer to part of the delay information or frequency shift information of the at least one CSI report. Or when the high-layer signaling is not configured, the terminal refers to all the delay information or frequency shift information.

[0209] Through the technical solution provided in the embodiment of the present application, the terminal can receive network signaling sent by the network side device or the activated CSI report setting to obtain one or more information of delay information and frequency shift information, and feed it back to the network through the CSI report, so as to facilitate the synchronization of the network and the terminal, so as to achieve better subsequent MTRP transmission.

[0210] In addition, by clarifying the priority of the MTRP CSI report and the CSI report carrying the delay information or frequency shift information, the terminal and the network can avoid inconsistent understanding of the priority of the CSI report, which may lead to network parsing errors in the CSI report. In addition, by defining terminal processing methods under some special timing relationships, invalid or inaccurate MTRP CSI feedback or feedback of MTRP CSI reports can be avoided or reduced, thereby reducing the complexity of the terminal calculating the MTRP CSI. Alternatively, repeated feedback of delay information or frequency shift information can be avoided or reduced, thereby reducing the complexity of terminal calculation. Furthermore, the network side device can reduce the feedback resources occupied by the CSI report carrying the delay information or frequency shift information, thereby improving resource utilization.

[0211] Optionally, the association described in the embodiments of the present application is not limited to the following explanations:

[0212] A is associated with B, which means A is B;

[0213] A is associated with B, which means that B can be obtained through A;

[0214] A is associated with B, which means that B can be determined through A;

[0215] Based on the same technical concept, an embodiment of the present application also provides a method for configuring a channel state information report.

[0219] In an embodiment of the present application, the network side device may configure the first CSI report fed back by the terminal to include: delay information, frequency shift information, or delay information and frequency shift information through network signaling, or may indicate to the terminal through DCI that the first CSI report fed back by the terminal includes: delay information, frequency shift information, or delay information and frequency shift information. In this way, the network side device can flexibly adjust the content of the CSI report based on known information or channel reciprocity, and can avoid the feedback of some useless information.

[0220] In an optional implementation, the method may further include at least one of the following:

[0221] (1) The network side device and the terminal send a second network signaling, wherein the second network signaling is used to indicate at least one first reference signal or at least one first reference signal set associated with the delay information, and the first reference signal set includes at least one first reference signal;

[0223] Through the above optional implementation, the network side device can control the content and size of the CSI report by indicating a reference signal or a reference signal set to the terminal, thereby avoiding feedback of some useless information and reducing network signaling overhead.

[0224] (3) The network side device sends a fourth network signaling to the terminal, where the fourth network signaling is used to indicate the accuracy of the delay information;

[0225] (4) The network side device and the terminal send a fifth network signaling, wherein the fifth network signaling is used to indicate the accuracy of the frequency shift information;

[0226] Through the above-mentioned optional implementation method, the network side device can also indicate the granularity of the delay information or frequency shift information to the terminal through network signaling, that is, the network side device can control the accuracy or unit of the delay information and / or frequency shift information fed back by the terminal, avoiding high-precision feedback of large delays or frequency shifts, and low-precision feedback of small delays or frequency shifts, thereby effectively utilizing feedback resources and improving the effectiveness of feedback information.

[0227] (5) The network side device and the terminal send a sixth network signaling, where the sixth network signaling is used to indicate the amount of delay information included in the first CSI report;

[0228] Through the above optional implementation, the network side device may also indicate the amount of delay information included in the CSI report to the terminal through network signaling, and the terminal may select a suitable reference signal or reference signal set to feedback its associated delay information based on the determined amount of delay information. In this case, some of the delay information fed back by the terminal may be an invalid value or a specific value, indicating that the delay information associated with the corresponding reference signal or reference signal group exceeds the available range.

[0229] (6) The network side device and the terminal send a seventh network signaling, where the seventh network signaling is used to indicate a maximum amount of delay information included in the first CSI report;

[0230] Through this optional implementation, the network side device can also indicate the maximum amount of delay information included in the CSI report to the terminal through network signaling, and the terminal selects an appropriate reference signal or reference signal set to feedback its associated delay information. Through these methods, the quality of the delay information or frequency shift information in the CSI report can be effectively improved to avoid feedback of too many values ​​that exceed the processing range.

[0231] (7) The network side device and the terminal send an eighth network signaling, where the eighth network signaling is used to indicate the amount of frequency shift information included in the first CSI report;

[0232] (8) The network side device and the terminal send a ninth network signaling, wherein the ninth network signaling is used to indicate a maximum amount of frequency shift information included in the first CSI report.

[0233] Through the above optional implementation manner, the network side device can indicate the number or maximum number of frequency shift information included in the first CSI report to the terminal through network signaling.

[0234] Optionally, the number or maximum number of frequency shift information-delay information pairs included in the first CSI report may also be indicated to the terminal by means of the above network signaling. Through these methods, the quality of the delay information or frequency shift information in the CSI report can be effectively improved, and too many values ​​exceeding the processing range can be avoided from being fed back.

[0236] a frequency shift associated with each second reference signal;

[0237] a frequency shift associated with each set of second reference signals;

[0238] an offset of the frequency shift of each second reference signal relative to the frequency shift associated with the base reference signal;

[0239] The frequency shift of each second reference signal set is an offset relative to the frequency shift associated with the base reference signal set.

[0240] In an optional implementation, when the first CSI report includes the frequency shift information, and the frequency shift information includes the frequency shift associated with each of the second reference signals or the frequency shift associated with each of the second reference signal sets, the number of the frequency shifts included in the first CSI report is one of the following:

[0241] a total number of second reference signals associated with the first CSI report;

[0242] The total number of second reference signal sets associated with the first CSI report;

[0243] The total number of second reference signals indicated by the network side device;

[0244] The total number of second reference signal sets indicated by the network side device;

[0245] a total number of second reference signals selected by the terminal;

[0246] The total number of second reference signal sets selected by the terminal.

[0247] In an optional implementation, when the frequency shift information includes the frequency shift, after the terminal feeds back the first CSI report, the method further includes: the network side device determines that a reference signal associated with the first CSI report or a physical downlink channel associated with the first CSI report has no frequency shift, or the network side device determines that a reference signal associated with the first CSI report or a physical downlink channel associated with the first CSI report has no frequency shift offset.

[0248] In an optional implementation, the frequency shift information is included in the first CSI report, where the frequency shift information includes an offset of the frequency shift of each of the second reference signals relative to the frequency shift associated with the reference reference signal or an offset of the frequency shift of each second reference signal set relative to the frequency shift associated with the reference reference signal set, and the number of the frequency shift offsets included in the first CSI report is one of the following:

[0249] The total number of second reference signals associated with the first CSI report minus 1;

[0250] The total number of second reference signal sets associated with the first CSI report minus 1;

[0251] The total number of second reference signals indicated by the network side device is reduced by 1;

[0252] The total number of the second reference signal sets indicated by the network side device is reduced by 1;

[0253] The total number of second reference signals selected by the terminal is reduced by 1;

[0254] The total number of the second reference signal sets selected by the terminal is reduced by 1.

[0255] In an optional implementation, the frequency shift information is included in the first CSI report, where the frequency shift information includes an offset of the frequency shift of each of the second reference signals relative to the frequency shift associated with the reference reference signal or an offset of the frequency shift of each second reference signal set relative to the frequency shift associated with the reference reference signal set, and the number of the frequency shift offsets included in the first CSI report is one of the following:

[0256] The total number of second reference signals associated with the first CSI report minus N;

[0257] The total number of second reference signal sets associated with the first CSI report minus N;

[0258] The total number of second reference signals indicated by the network side device minus N;

[0259] The total number of the second reference signal sets indicated by the network side device minus N;

[0260] The total number of second reference signals selected by the terminal minus N;

[0261] The total number of second reference signal sets selected by the terminal is reduced by N.

[0262] N is an integer greater than 1. For example, the above-mentioned reference reference signal or reference reference signal set can be N of the multiple second reference signals or second reference signal sets associated with the first CSI report, for example: the first N or the last N, or, N of the multiple second reference signals or second reference signal sets indicated by the network side device, or, N of the multiple second reference signals or second reference signal sets selected or indicated by the terminal.

[0263] In an optional implementation, the method further includes:

[0264] The network side device sends a tenth network signaling to the terminal, wherein the tenth network signaling is used to indicate that the frequency shift information includes the frequency shift or the offset of the frequency shift.

[0265] In an optional implementation, the method further includes:

[0266] The network side device receives the first CSI report fed back by the terminal.

[0267] In an optional implementation, the method further includes:

[0268] In a first case, the network side device determines that the terminal will feed back the first CSI report and performs a first target operation;

[0269] The first situation includes at least one of the following:

[0270] The most recent transmission timing of all reference signals associated with the first CSI report is later than the CSI reference resource associated with the second CSI report and earlier than the feedback time slot or feedback symbol associated with the second CSI report, and the second CSI report includes MTRP CSI;

[0271] The most recent transmission timing of any reference signal associated with the first CSI report is later than the CSI reference resource associated with the second CSI report and earlier than the feedback time slot or feedback symbol associated with the second CSI report;

[0272] A feedback time slot or feedback symbol associated with the first CSI report is later than a CSI reference resource associated with the second CSI report, and earlier than a feedback time slot or feedback symbol associated with the second CSI report;

[0273] The first target operation includes at least one of the following:

[0274] Not feeding back the second CSI report;

[0275] Feedback part of the second CSI report;

[0276] Indicating in the first CSI report whether to feed back the second CSI report;

[0277] Indicate in the first CSI report whether to feed back part of the content of the second CSI report.

[0278] Since the CSI of delay information or frequency shift information may affect the calculation of MTRP CSI, there are some situations in which the CSI feedback of delay information or frequency shift information may cause the MTRP CSI to be invalid or inaccurate, thereby causing performance loss. Therefore, in the above optional implementation, when the network side device determines that the above first situation is met, in one implementation, it is determined that the terminal feeds back the first CSI report and does not feed back the second CSI report. In another implementation, it is determined that the terminal only feeds back part of the content of the second CSI report. In another implementation, it is determined that the terminal indicates in the first CSI report that the terminal feeds back the second CSI report or part of the content of the second CSI report, and then according to the instruction in the first CSI report, it is determined that the terminal feeds back the second CSI report or part of the content of the second CSI report. In this way, invalid or inaccurate MTRP CSI feedback or feedback of MTRP CSI reports can be avoided or reduced, thereby reducing the complexity of the terminal calculating MTRP CSI, and avoiding the problem of transmission performance degradation caused by feedback of invalid information.

[0279] In an optional implementation, the method further includes: in a second case, the network side device determines that the terminal feeds back a second CSI report, and performs a second target operation, wherein the second CSI report includes MTRP CSI;

[0280] The second situation includes at least one of the following:

[0281] The most recent transmission timing of all reference signals associated with the second CSI report is later than the CSI reference resource associated with the first CSI report and earlier than the feedback time slot or feedback symbol associated with the first CSI report;

[0282] The most recent transmission timing of all reference signals associated with the MTRP CSI associated with the second CSI report is later than the CSI reference resource associated with the first CSI report and earlier than the feedback time slot or feedback symbol associated with the first CSI report;

[0283] The most recent transmission timing of any reference signal associated with the second CSI report is later than the CSI reference resource associated with the first CSI report and earlier than the feedback time slot or feedback symbol associated with the first CSI report;

[0284] The most recent transmission timing of any reference signal associated with the MTRP CSI associated with the second CSI report is later than the CSI reference resource associated with the first CSI report and earlier than the feedback time slot or feedback symbol associated with the first CSI report;

[0285] A feedback time slot or feedback symbol associated with the second CSI report is later than a CSI reference resource associated with the first CSI report, and earlier than a feedback time slot or feedback symbol associated with the first CSI report;

[0286] The second target operation includes at least one of the following:

[0287] Not feeding back the first CSI report;

[0288] Feedback part of the first CSI report;

[0289] Indicating in the second CSI report whether to feed back the first CSI report;

[0290] Indicate in the second CSI report whether to feed back part of the content of the first CSI report.

[0291] In the above optional implementations, when the network side device determines that the above second situation is met, in one implementation, it is determined that the terminal feeds back the second CSI report but does not feed back the first CSI report; in another implementation, it is determined that the terminal feeds back only part of the first CSI report; in yet another implementation, it is determined that the terminal instructs the terminal to feed back the first CSI report or part of the first CSI report in the second CSI report, and then according to the instruction in the second CSI report, it is determined that the terminal feeds back the first CSI report or part of the first CSI report. In this way, repeated feedback of delay information or frequency shift information can be avoided or reduced, thereby reducing the calculation complexity of the terminal. Further, the network side device can reduce the feedback resources occupied by the CSI report carrying delay information or frequency shift information, and improve resource utilization.

[0292] In an optional implementation, the method may further include: the network side device sends a twelfth network signaling to the terminal, wherein the twelfth network signaling is used to indicate that the PMI associated with the second CSI report is calculated by a target symbol associated with a reference CSI reference resource associated with the second CSI report, and wherein the second CSI report includes a multi-transmission node MTRP CSI.

[0293] In an optional implementation, the method may further include: the network side device sending a thirteenth network signaling to the terminal, wherein the thirteenth network signaling is used to indicate one of the following:

[0294] The terminal obtains the second CSI report based on target feedback of at least one of the first CSI reports associated with the second CSI report, wherein the target feedback includes one of the following that is no later than the CSI reference resource associated with the second CSI report: the most recent feedback, any feedback, and a feedback agreed upon by a protocol;

[0295] The terminal does not acquire the second CSI report based on any feedback of at least one first CSI report associated with the second CSI report.

[0296] In an optional implementation, the method may further include at least one of the following:

[0297] The network side device sends a fourteenth network signaling to the terminal, wherein the fourteenth network signaling is used to instruct the terminal to obtain the second CSI report based on a target value, wherein the target value includes one of the following: a frequency shift value, a delay value, a frequency shift offset, and a delay offset:

[0298] The network side device sends a fifteenth network signaling to the terminal, wherein the fifteenth network signaling is used to indicate obtaining the second CSI report with reference to all or part of the target information of at least one of the first CSI reports.

[0299] Through the above method provided by the embodiment of the present application, the network side device can obtain one or more information of delay information and frequency shift information by sending network signaling settings, and by defining the terminal processing method under some special timing relationships, it can avoid or reduce invalid or inaccurate MTRP CSI feedback or MTRP CSI report feedback, thereby reducing the complexity of terminal calculation of MTRP CSI. Alternatively, it can avoid or reduce repeated feedback of delay information or frequency shift information, thereby reducing the complexity of terminal calculation.
