[0036] In order to better understand the technical solutions provided by this application, we first introduce the relevant technologies involved in this application.

[0037] 1. CSI Architecture

[0038] Generally, the CSI architecture can be divided into two parts: downlink CSI and uplink CSI. The downlink CSI architecture includes downlink physical channels and downlink reference signals, while the uplink CSI architecture includes uplink physical channels and uplink reference signals.

[0039] 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).

[0040] In 5G systems, CSI is mainly used in adaptive antenna beamforming (ABF) and multiple input multiple output (MIMO) technologies to improve wireless transmission bandwidth and reliability.

[0041] In general, the 5G CSI architecture is a very important technology in 5G communication systems, playing an important role in improving wireless transmission bandwidth and reliability and interference coordination.

[0042] 2. CSI Report Content

[0043] Typically, the terminal may determine through higher layer signaling or default rules that the 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'.

[0044] 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.

[0045] 3. CSI Acquisition

[0046] The network associates each CSI report configuration (CSI-ReportConfig) with a reference signal resource configuration for channel measurement (CSI-ResourceConfig), 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. The terminal obtains the corresponding channel information by measuring the reference resources associated with these resource configurations. Currently, the corresponding channel information can generally be considered as baseband digital precoding matrix information and baseband modulation scheme recommendation information. The terminal further obtains the corresponding CSI information based on the codebook configuration information and report content associated with the CSI report configuration and based on uplink channel feedback.

[0047] For PMI feedback, if the Rel-15 Type 1 codebook is used, the terminal measures up to eight channel measurement reference signals and selects one of them to feedback the PMI. If the Rel-15 Type 2 / Rel-16 Type 2 / Rel-17 codebook is used, the terminal measures one channel measurement reference signal and feedbacks the PMI associated with that reference signal. If the Rel-18 Type 2 coherent joint transmission (CJT) codebook is used, the terminal measures up to four channel measurement reference signals, assumes that the four reference signals are associated with four TRPs, and uses the channels associated with the four reference signals to obtain and feedback the PMI. If it is a Rel-18 Type2 prediction codebook, for periodic / semi-continuous channel measurement reference signals, the network side device configures one reference signal, and the terminal uses multiple transmission moments 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 moment of the 12 reference signals to obtain the predicted PMI.

[0048] Furthermore, when acquiring CJT CSI, the terminal can report the delay offset between two TRPs as 1 / B*N3, where B is the CSI reference signal bandwidth and N3 is the number of PMI subbands. This means that if the delay offset between two TRPs exceeds this range, the performance of the PMI obtained by the terminal will degrade. In other words, the network-side device cannot obtain the delay offset between two TRPs through PMI.

[0049] The CSI associated with the Rel-15 Type 2 / Rel-16 Type 2 / Rel-17 codebook 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.

[0050] However, there is no CSI report feedback framework in the related art to support the terminal to assist the network side equipment 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 equipment.

[0051] The following 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 in combination with the accompanying drawings.

[0052] FIG2 illustrates a flow chart of a method for obtaining a channel state information report according to an embodiment of the present application. Method 200 may be executed by a terminal. In other words, the method may be executed by software or hardware installed on the terminal. As shown in FIG2 , the method may include the following steps.

[0053] 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.

[0054] 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.

[0055] 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 that the first CSI report includes the target information based on the first network signaling sent by the network side device.

[0056] In the above implementation, the terminal can receive signaling sent by the network side device, which can be network signaling, such as Radio Resource Control (RRC) signaling or Medium 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 transmission performance of multiple transmission nodes (Multi Transmission and Reception Point, MTRP). Optionally, the terminal determines, based on network signaling or DCI sent by the network-side device, that the first CSI report includes one of the following: delay information, frequency shift information, or delay information and frequency shift information. That is, the network-side device may configure, through network signaling, the first CSI report fed back by the terminal to include: delay information, frequency shift information, or delay information and frequency shift information, or may 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, thereby avoiding the feedback of some useless information.

[0057] In another optional implementation, the terminal determines that the first channel state information CSI report to be fed back 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.

[0058] In an optional implementation, the method may further include at least one of the following:

[0059] (1) The terminal determines, based on second network signaling sent by a 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;

[0060] (2) The terminal determines, based on 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;

[0061] In an optional implementation of the embodiment of the present application, the network device may control the content and size of the CSI report by indicating a reference signal or reference signal set to the terminal, thereby avoiding the feedback of some useless information and reducing network signaling overhead. It can be understood that the network device may indicate some reference signals or reference signal sets from multiple reference signals or reference signal sets to obtain delay information or frequency shift information.

[0062] Regarding 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.

[0063] Alternatively, the terminal can determine the reference signal or reference signal set for obtaining delay and frequency shift information based on network signaling. This means that the delay and frequency shift information share the same reference signal or reference signal set. For example, if a CSI report is associated with four reference signal sets, the network device instructs the terminal via network signaling to use reference signal sets 0 / 1 / 2 for obtaining delay and frequency shift information.

[0064] 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 avoid the waste of resources caused by the terminal feeding back known information to the network side device.

[0065] (3) The terminal determines the accuracy of the delay information based on the fourth network signaling sent by the network side device;

[0066] (4) The terminal determines the accuracy of the frequency shift information based on the fifth network signaling sent by the network side device;

[0067] 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 accuracy to feed back large delays or frequency shifts, and low accuracy to feed back small delays or frequency shifts, thereby effectively utilizing feedback resources and improving the effectiveness of feedback information.

[0068] One method for effectively utilizing feedback resources is to indicate the accuracy to the network from the terminal. Specifically, the terminal can select appropriate time units or frequency shift units to feedback the delay and / or frequency shift information based on the delay and frequency shift information it obtains. In this manner, the network device can indicate a total feedback overhead to the terminal, and the terminal can provide the highest accuracy possible for feedback of the delay and / or frequency shift information without exceeding the total feedback overhead.

[0069] The accuracy of the time 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 the FFT size) or K times pi (K is a rational number), etc.

[0070] 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 from them to feed back corresponding delay information or frequency shift information.

[0071] (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;

[0072] (6) The terminal determines, based on the seventh network signaling sent by the network-side device, a maximum amount of delay information included in the first CSI report;

[0073] (7) The terminal determines, based on eighth network signaling sent by the network-side device, the amount of frequency shift information included in the first CSI report;

[0074] (8) The terminal determines the maximum amount of frequency shift information included in the first CSI report based on the ninth network signaling sent by the network side device.

[0075] It should be noted that the above-mentioned first to ninth network signalings can 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 can be the same network signaling.

[0076] In an optional implementation of the embodiment of the present application, the network-side device may further indicate to the terminal via network signaling the amount of latency information included in the CSI report. Based on the determined amount of latency information, the terminal may select an appropriate reference signal or reference signal set to feedback its associated latency information. In this case, some of the latency information feedback provided by the terminal may contain invalid values ​​or specific values, indicating that the latency information associated with the corresponding reference signal or reference signal set exceeds the available range.

[0077] Alternatively, the network-side device may further indicate to the terminal the maximum amount of delay information included in the CSI report through network signaling, and the terminal selects an appropriate reference signal or reference signal set to feed back its associated delay information. Furthermore, 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 the feedback of too many values ​​that exceed the processing range can be avoided.

[0078] In an optional implementation, 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:

[0079] (1) Frequency shifts associated with each second reference signal; that is, the 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.

[0080] (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.

[0081] 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.

[0082] Optionally, when the first CSI report includes frequency shift information for the frequency shifts associated with each of the above-mentioned second reference signals or the frequency shifts 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.

[0083] (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 this embodiment of the present application, the reference reference signal refers to a reference signal serving 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.

[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 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. In other words, 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.

[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 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. In other words, the 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.

[0086] (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.

[0087] 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 device minus 1, or the total number of second reference signal sets selected by the terminal minus 1. In other words, 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 device, or one of multiple second reference signal sets selected by the terminal.

[0088] 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. In other words, the 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.

[0089] In an optional implementation of an embodiment of the present application, when the first CSI report includes frequency shift information, one piece of 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 an 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 offsets of other TRPs relative to the reference TRP.

[0090] In the case where a piece of 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 pieces 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 pieces may be the number of second reference signal sets or second reference signals indicated by a network-side device. In yet another implementation, the number of frequency shift information pieces may be the number of second reference signal sets or second reference signals selected by the terminal.

[0091] Optionally, when the frequency shift information is 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 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. The terminal can assume that there is no frequency shift to process the impact of subsequent frequency shift. At this time, if there is 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 domain quasi-co-location information.

[0092] Similarly, when the CSI report includes delay information, one piece of delay information can 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, in 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 offsets of other TRPs relative to the reference TRP.

[0093] For the case where a delay information may be a delay associated with a first reference signal or a first reference signal set, the quantity of delay information is the first reference signal set or the number of first reference signals associated with the first CSI report, or the quantity 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 quantity of delay information is the number of first reference signal sets or the number of first reference signals selected by the terminal.

[0094] For the case where a piece of delay information can be a delay offset; that is, in this optional implementation, each piece of delay information in the multiple pieces of delay information included in the first CSI report is the delay offset of one second reference signal or second reference signal set relative to the reference reference signal or reference reference signal set. Optionally, the amount of delay information in the first CSI report can be the total number of first reference signals or first reference signal sets associated with the first CSI report minus one, or the total number of first reference signals or first reference signal sets indicated by the network-side device minus one, or the total number of first reference signals or first reference signal sets selected by the terminal minus one. That is, the reference reference signal or reference reference signal set can be one of multiple first reference signals or first reference signal sets associated with the first CSI report, or one of multiple first reference signals or first reference signal sets indicated by the network-side device, or one of 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.

[0095] Optionally, when the delay information is a time 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 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 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 domain quasi-co-location information.

[0096] In an optional implementation, the terminal may determine, based on a tenth network signaling sent by a network-side device, whether the frequency shift information includes the frequency shift or the frequency shift offset, or determine whether the delay information includes the delay or the delay offset. It can be understood that the network may configure, through higher-layer signaling, whether the terminal feeds back the frequency shift or delay, or the frequency shift offset or the delay offset.

[0097] S212: The terminal obtains the target information based on the reference signal associated with the first CSI report.

[0098] 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. 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 based on a reference signal or reference signal set configured by a network-side device, or may be indicated by the network-side device through network signaling, or may be selected by the terminal based on measurement results, and may be determined specifically based on actual conditions.

[0099] 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.

[0100] In an optional implementation, when the terminal obtains target information in the first CSI report, the number of CSI processing units (CPUs) associated with the first CSI report is related to at least one of the following:

[0101] (1) the number of reference signal sets associated with the first CSI report;

[0102] (2) The target information included in the first CSI report.

[0103] That is, 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 items of delay information or frequency shift information.

[0104] In another optional implementation, for 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 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.

[0105] 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 carrying 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.

[0106] In the above optional implementation, when the frequency shift information included in the first CSI report is a frequency shift offset, or when the delay information included in the first CSI report is a 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 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 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 device in the first CSI report that a certain reference signal or a reference signal set is a reference for the delay offset.

[0107] In an optional implementation, after S212, the method may further include: the terminal feeding 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 fact that the feedback priority of the first CSI report is higher than that of the second CSI report indicates 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 preferentially processed or fed back.

[0108] 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 meet at least one of the following conditions:

[0109] (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-persistent CSI report, and aperiodic CSI report;

[0110] (2) The first CSI report and the second CSI report are associated with the same channel type, where the channel type includes one of the following: Physical Uplink Shared Channel (PUSCH) and Physical Uplink Control Channel (PUCCH);

[0111] (3) The first CSI report and the second CSI report are associated with the same serving cell;

[0112] (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:

[0113] a) the quasi-co-site 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;

[0114] 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 including 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.

[0115] c) an association relationship between the second CSI report and the first CSI report established through a physical cell identifier.

[0116] d) an association relationship between the second CSI report and the first CSI report established through the measurement bandwidth part.

[0117] In an actual system, there may be a situation where multiple CSI reports conflict or multiple CSI reports are multiplexed into one channel resource (for example, multiplexed into 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 generally a CSI report associated with joint measurement of multiple reference signals) conflict or are multiplexed.

[0118] 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., the MTRP CSI report) because the delay information or frequency shift information is more important for helping the network-side device achieve higher quality MTRP transmission. In addition, the feedback of the delay information or frequency shift information may not be as frequent as the feedback of the MTRP CSI 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 (DPS) CSI, etc.) in the CSI report.

[0119] Furthermore, optionally, more detailed conditions 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 conditions is met, the priority associated with the first CSI report is higher than that of the second CSI report. The conditions include:

[0120] 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-persistent CSI report or aperiodic CSI report) as the MTRP CSI report;

[0121] 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;

[0122] iii. The first CSI report carrying delay information or frequency shift information is associated with the same serving cell as the MTRP CSI report;

[0123] iv. The first CSI report carrying delay information or frequency shift information is associated with the MTRP CSI report;

[0124] In particular, the association between the first CSI report carrying the delay information or frequency shift information and the MTRP CSI report may be established in at least one of the following ways:

[0125] a) Among the reference signals associated with the MTRP CSI report, there is a quasi-co-site reference signal, which is the reference signal associated with the CSI report carrying the delay information and / or frequency shift information;

[0126] 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.

[0127] c) Establishing an association relationship through network signaling associated with the MTRP CSI report (serving cell configuration ServingCellConfig); for example, the MTRP CSI report and the first CSI report carrying the delay information or frequency shift information are associated with the same network signaling, such as ServingCellConfig or CSI-MeasConfig;

[0128] 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;

[0129] 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.

[0130] Through the above method, the priority of the MTRP CSI report and the first CSI report carrying the delay information or frequency shift information can be clarified, avoiding inconsistent understanding of the priority of the CSI report between the terminal and the network side device, which leads to errors in the network side device parsing the CSI report. At the same time, more important CSI information can be fed back to the network side device as much as possible to ensure the stability of transmission.

[0131] 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.

[0132] The first situation may include at least one of the following:

[0133] (1) The most recent transmission opportunity 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;

[0134] 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.

[0135] Optionally, the feedback time slot or feedback symbol may be the first time slot or the first symbol among all time slots or symbols associated with the second CSI report, or may be a time slot or a symbol agreed upon in a protocol.

[0136] (2) The most recent transmission opportunity 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 slot or feedback symbol associated with the second CSI report;

[0137] (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.

[0138] The first target operation includes at least one of the following:

[0139] a) not feeding back the second CSI report;

[0140] b) Feedback partial content of the second CSI report; for example, only feedback of the CSI report part 1, i.e., Part 1, of the second CSI report, or only feedback of the STRP CSI in the second CSI report without feedback of the MTRP CSI in the CSI report.

[0141] c) indicating in the first CSI report whether to feed back the second CSI report;

[0142] d) indicating in the first CSI report whether to feed back part of the content of the second CSI report.

[0143] 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.

[0144] 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.

[0145] Because CSI containing delay or frequency shift information may affect the calculation of MTRP CSI, in some cases, CSI feedback containing delay or frequency shift information may render the MTRP CSI invalid or inaccurate, resulting in performance loss. For example, in Figure 3, when the reference signal used to obtain CSI containing delay or frequency shift information appears between the CSI reference resource associated with the MTRP CSI and the CSI feedback, the MTRP CSI may be inaccurate or have a large error because the MTRP CSI is calculated based on the delay and / or frequency shift information previously measured on the CSI reference resource, rather than the measurement results of the most recently measured delay and / or frequency shift information.

[0146] The above situations may include at least one of the following:

[0147] (1) The most recent transmission opportunity of all reference signals associated with the first CSI report associated with delay information or frequency shift information is later than the CSI reference resource associated with the MTRP CSI report and earlier than the feedback slot or feedback symbol associated with the MTRP CSI report, as shown in FIG3 ;

[0148] 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.

[0149] (2) The most recent transmission opportunity 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;

[0150] 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.

[0151] (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;

[0152] 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.

[0153] 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 that is 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. 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 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.

[0154] For invalid or inaccurate MTRP CSI or MTRP CSI report, the terminal's handling method includes at least one of the following:

[0155] (1) The terminal does not feed back the MTRP CSI report;

[0156] (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, without feeding back the MTRP CSI in the CSI report;

[0157] (3) The terminal indicates in the first CSI report carrying the delay information or frequency shift information whether to feed back the MTRP CSI report. For example, if the terminal finds that the MTRP CSI report is inaccurate or invalid, it may indicate in the first CSI report carrying the delay information or frequency shift information that the MTRP CSI report will not be fed back later. If the terminal finds that the MTRP CSI report is accurate, it may indicate in the first CSI report carrying the delay information or frequency shift information that the MTRP CSI report will be fed back later.

[0158] (4) The terminal indicates in the first CSI report carrying the delay information or frequency shift information whether to feed back partial content of the MTRP CSI report. For example, if the terminal finds that the MTRP CSI report is inaccurate or invalid, it may 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 that the CSI report does not include MTRP CSI but only STRP CSI.

[0159] By adopting the above-mentioned method, invalid or inaccurate MTRP CSI feedback or MTRP CSI report feedback can be avoided or reduced, thereby reducing the complexity of the terminal in calculating the MTRP CSI and avoiding the problem of transmission performance degradation caused by feedback of invalid information.

[0160] 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.

[0161] The second situation may include at least one of the following:

[0162] (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 slot or feedback symbol associated with the first CSI report;

[0163] (2) The most recent transmission opportunity 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 slot or feedback symbol associated with the first CSI report; that is, the most recent transmission opportunity 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 slot or feedback symbol associated with the first CSI report;

[0164] (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 slot or feedback symbol associated with the first CSI report;

[0165] (4) The most recent transmission opportunity 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 slot or feedback symbol associated with the first CSI report; that is, the most recent transmission opportunity 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 slot or feedback symbol associated with the first CSI report;

[0166] (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.

[0167] The second target operation includes at least one of the following:

[0168] a) not feeding back the first CSI report;

[0169] b) feeding back partial content of the first CSI report; for example, feeding back only CSI report part 1, i.e., Part 1, of the first CSI report; or feeding back only frequency offset information in the first CSI report without feeding back delay information in the first CSI report; or feeding back only delay information in the first CSI report without feeding back frequency offset information in the first CSI report.

[0170] c) indicating in the second CSI report whether to feed back the first CSI report;

[0171] d) indicating in the second CSI report whether to feed back part of the content of the first CSI report.

[0172] 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 first CSI report, or the terminal indicates in the second CSI report whether to feed back the first CSI report or part of the first CSI report.

[0173] 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.

[0174] In actual systems, MTRP CSI may affect the acquisition and feedback of the CSI for the delay information or frequency shift information. Therefore, in some cases, the calculation and feedback of the MTRP CSI eliminates the need for calculation and feedback of the CSI for the delay information or frequency shift information. For example, in Figure 4, when the feedback of the MTRP CSI occurs between the CSI reference resource associated with the first CSI report carrying the delay information and frequency shift information and the CSI feedback, since the MTRP CSI carries the delay information, to avoid redundant delay information feedback, the delay information is not fed back in the first CSI report carrying the delay information and frequency shift information.

[0175] The above situation may include at least one of the following situations.

[0176] 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 delay information or frequency shift information and earlier than the feedback slot or feedback symbol associated with the CSI report carrying delay information and / or frequency shift information;

[0177] 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 delay information or frequency shift information and earlier than the feedback slot or feedback symbol associated with the CSI report carrying delay information and / or frequency shift information;

[0178] iii. The feedback slot or feedback symbol associated with the MTRP CSI report is later than the CSI reference resource associated with the first CSI report carrying delay information or frequency shift information and earlier than the feedback slot or feedback symbol associated with the CSI report carrying delay information and / or frequency shift information;

[0179] 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.

[0180] The CSI of the time 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:

[0181] 1. The terminal does not feedback the first CSI report carrying 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 delay information and after the CSI reference resource associated with the first CSI report carrying delay information, the CSI report carrying delay information is not fed back or feedback is skipped.

[0182] 2. The terminal only feeds back partial content of the first CSI report carrying the delay information or frequency shift information. Optionally, the partial content is partial content of the delay information, or partial content of the frequency shift information, or delay information, or frequency shift information, or CSI report part 1. 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 MTRP CSI 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.

[0183] 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 may indicate in the MTRP CSI report that there is no subsequent first CSI report carrying the delay information or frequency shift information, i.e., the first CSI report carrying the delay information or frequency shift information is skipped for feedback.

[0184] 4. The terminal indicates in the MTRP CSI report whether to feed back partial content of the first CSI report carrying delay information or frequency shift information. Optionally, the partial content is partial content of delay information, partial content of frequency shift information, delay information, frequency shift information, or CSI report part 1. For example, if the terminal finds that the MTRP CSI report can accurately carry delay information, it may indicate in the MTRP CSI report that the first CSI report that subsequently carries delay information and frequency shift information only feeds back frequency shift information. Alternatively, it may indicate in the MTRP CSI report that the first CSI report that subsequently carries delay information and frequency shift information only feeds back CSI report part 1.

[0185] By using the above approach, repeated feedback of delay information or frequency shift information can be avoided or reduced, thereby reducing terminal computational complexity. Furthermore, network-side devices can reduce the feedback resources occupied by the CSI report carrying delay information or frequency shift information, thereby improving resource utilization.

[0186] In an optional implementation, the method further includes: the terminal obtaining the second CSI report, wherein the second CSI report includes MTRP CSI.

[0187] Optionally, the PMI associated with the second CSI report is calculated by referring to the target symbol associated with the CSI reference resource associated with the second CSI report, wherein the target symbol includes one of the following: the first symbol associated with the CSI reference resource, the last symbol associated with the CSI reference resource, and a symbol agreed upon by the protocol among multiple symbols associated with the CSI reference resource.

[0188] Optionally, when the first CSI report is associated with the second CSI report (for example, having the above-mentioned target association relationship), 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 among multiple symbols associated with the CSI reference resource, or a symbol agreed upon by the protocol. That is, 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 calculated by compensating to the CSI reference resource, or calculated aligned to the CSI reference resource. 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.

[0189] Optionally, the terminal may also determine, according to a twelfth network signaling or default rule or protocol agreement, that the PMI associated with the second CSI report is calculated by using 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 using a target symbol associated with the 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 using a target symbol associated with the 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 using a target symbol associated with the reference CSI reference resource associated with the second CSI report.

[0190] 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.

[0191] 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 therewith that includes delay information or frequency shift information. A possible reference method is for the terminal to obtain the MTRP CSI report based on a specific time, where 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 data transmission is performed 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.

[0192] For a specific time, one possible approach is CSI reference resources. The CSI reference resource can be a downlink time slot or an uplink time slot, which 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 CSI reference signal (CSI Reference Signal, CSI-RS) transmission, 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.

[0193] For a specific time, another possible method is a specific symbol of the CSI reference resource, where the specific symbol can 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 or non-downlink symbol. For example, the terminal measures the channel at the CSI-RS transmission timing, compensates for the effect of frequency shift on the first symbol of the CSI reference resource, and then calculates the corresponding MTRP PMI and feeds it back to the network.

[0194] Optionally, for a specific time, the terminal may 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 a time slot associated with the CSI reference resource. For example, the network indicates that the calculation is based on the time slot or the first symbol. For another example, the protocol agreed rules stipulate that for CSI reference resources that include both uplink and downlink symbols, the calculation is based on the first downlink symbol; 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.

[0195] In an optional implementation, before the terminal obtains the second CSI report, when the second CSI report is associated with at least one of the first CSI reports, the terminal may determine, based on thirteenth network signaling from a network-side device, one of the following:

[0196] (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, or a feedback agreed upon by the protocol; optionally, the most recent feedback is feedback that is no later than the CSI reference resource associated with the second CSI report, and the any feedback or the feedback agreed upon by the protocol may be feedback that is no later than the CSI reference resource associated with the second CSI report.

[0197] (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, it does not consider the feedback content of the at least one first CSI report.

[0198] In an optional implementation of the 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 delay information or frequency shift information is periodic or semi-continuous CSI feedback, the network may instruct the terminal through signaling according to which feedback of the first CSI report (or not) to obtain the MTRP CSI report, including at least one of the following:

[0199] 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;

[0200] 2. The terminal obtains the MTRP CSI report based on a primary feedback of the at least one first CSI report including the delay information or the frequency shift information associated with the MTRP CSI report;

[0201] 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, it does not consider the feedback content of the at least one first CSI report;

[0202] Optionally, the most recent feedback is feedback no later than the CSI reference resource associated with the second CSI report; the feedback may be any one time, or a feedback agreed upon in the protocol.

[0203] 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.

[0204] 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:

[0205] (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;

[0206] (2) The terminal determines 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 based on the fifteenth network signaling sent by the network side device.

[0207] 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.

[0208] The network side device may select at least part of the delay information or frequency shift information from the multiple delay information or frequency shift information through signaling or a default rule at the transceiver end for obtaining the MTRP CSI report, including at least one of the following implementations.

[0209] 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, where 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 that is 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 that is 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.

[0210] 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 interval associated with the MTRP CSI report. Alternatively, the default rule may be for the terminal to obtain the second value based on 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 that is greater than or equal to the second value, the terminal needs to consider this 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 that is 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.

[0211] Furthermore, when the terminal obtains the second CSI report, the network-side device may indicate, through higher-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. Alternatively, when the higher-layer signaling is not configured, the terminal refers to all the delay information or frequency shift information.

[0212] 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 feedback it 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.

[0213] In addition, by clarifying the priority of the MTRP CSI report and the CSI report that carries the delay information or frequency shift information, inconsistent understanding of the priority of the CSI report between the terminal and the network is avoided, which leads to errors in the network parsing of 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. Further, the network-side device can reduce the feedback resources occupied by the CSI report that carries the delay information or frequency shift information, thereby improving resource utilization.

[0214] Optionally, the association described in the embodiments of the present application is not limited to the following explanations:

[0215] A is associated with B, which means A is B;

[0216] A is associated with B, which means that B can be obtained through A;

[0217] A is associated with B, which means that B can be determined through A.

[0218] Based on the same technical concept, an embodiment of the present application also provides a method for configuring a channel state information report.

[0219] Figure 5 illustrates a flow chart of a method for configuring channel state information reporting, as provided in an embodiment of the present application. Method 500 can be executed by a network-side device. In other words, the method can be executed by software or hardware installed on the network-side device. Where necessary, the following embodiments only describe the operation of the network-side device. For other matters not covered, please refer to the above description of method 200.

[0220] As shown in FIG5 , the method may include the following steps.

[0221] S510, a network-side device sends a first network signaling to a terminal, wherein the first network signaling is used to configure a first CSI report fed back by the terminal to include target information, and the target information includes at least one of the following: delay information and frequency shift information.

[0222] In an embodiment of the present application, the network device may configure, through network signaling, the first CSI report fed back by the terminal to include: latency information, frequency shift information, or both latency and frequency shift information. Alternatively, the network device may indicate to the terminal, through DCI, that the first CSI report fed back by the terminal includes: latency information, frequency shift information, or both latency and frequency shift information. In this manner, the network device can flexibly adjust the content of the CSI report based on known information or channel reciprocity, thereby avoiding the feedback of useless information.

[0223] In an optional implementation, the method may further include at least one of the following:

[0224] (1) The network-side device and the terminal send 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;

[0225] (2) The network-side device sends a third network signaling to the terminal, wherein the third network signaling is used to indicate at least one second reference signal or at least one second reference signal set associated with the frequency shift information, and the second reference signal set includes at least one second reference signal;

[0226] 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.

[0227] (3) The network-side device and the terminal send a fourth network signaling, wherein the fourth network signaling is used to indicate the accuracy of the delay information;

[0228] (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;

[0229] 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.

[0230] (5) The network-side device and the terminal send sixth network signaling, where the sixth network signaling is used to indicate the amount of delay information included in the first CSI report;

[0231] With the above optional implementation, the network device may further indicate to the terminal via network signaling the amount of latency information included in the CSI report. Based on the determined amount of latency information, the terminal may select an appropriate reference signal or reference signal set to feedback its associated latency information. In this case, some of the latency information feedback by the terminal may contain invalid values ​​or specific values, indicating that the latency information associated with the corresponding reference signal or reference signal set exceeds the available range.

[0232] (6) The network-side device and the terminal send seventh network signaling, where the seventh network signaling is used to indicate the maximum amount of delay information included in the first CSI report;

[0233] With this optional implementation, the network device can also indicate to the terminal, via network signaling, the maximum amount of delay information to include in the CSI report. The terminal then selects an appropriate reference signal or reference signal set to feedback its associated delay information. These approaches can effectively improve the quality of the delay or frequency shift information in the CSI report and avoid feedback of excessive values ​​that exceed the processing range.

[0234] (7) The network-side device and the terminal send an eighth network signaling, wherein the eighth network signaling is used to indicate the amount of frequency shift information included in the first CSI report;

[0235] (8) The network side device and the terminal send ninth network signaling, wherein the ninth network signaling is used to indicate the maximum amount of frequency shift information included in the first CSI report.

[0236] Through the above optional implementation manner, the network-side device may indicate the number or maximum number of frequency shift information included in the first CSI report to the terminal through network signaling.

[0237] 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 using the above-mentioned network signaling method. Through these methods, the quality of the delay information or frequency shift information in the CSI report can be effectively improved, and excessive feedback exceeding the processing range can be avoided.

[0238] In an optional implementation, 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:

[0239] a frequency shift associated with each second reference signal;

[0240] frequency shifts associated with each set of second reference signals;

[0241] an offset of the frequency shift of each second reference signal relative to the frequency shift associated with the base reference signal;

[0242] The frequency shift of each second reference signal set is an offset relative to the frequency shift associated with the base reference signal set.

[0243] 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 second reference signal set, the number of the frequency shifts included in the first CSI report is one of the following:

[0244] a total number of second reference signals associated with the first CSI report;

[0245] a total number of second reference signal sets associated with the first CSI report;

[0246] the total number of second reference signals indicated by the network-side device;

[0247] the total number of second reference signal sets indicated by the network-side device;

[0248] the total number of second reference signals selected by the terminal;

[0249] The total number of second reference signal sets selected by the terminal.

[0250] 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 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 network side device 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.

[0251] In an optional implementation, the first CSI report includes the frequency shift information, where the frequency shift information includes an offset of the frequency shift of each second reference signal 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. The number of the frequency shift offsets included in the first CSI report is one of the following:

[0252] The total number of second reference signals associated with the first CSI report minus 1;

[0253] The total number of second reference signal sets associated with the first CSI report minus 1;

[0254] The total number of second reference signals indicated by the network side device is reduced by 1;

[0255] The total number of the second reference signal sets indicated by the network side device is reduced by 1;

[0256] The total number of second reference signals selected by the terminal is reduced by 1;

[0257] The total number of the second reference signal sets selected by the terminal is reduced by 1.

[0258] In an optional implementation, the first CSI report includes the frequency shift information, where the frequency shift information includes an offset of the frequency shift of each second reference signal 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. The number of the frequency shift offsets included in the first CSI report is one of the following:

[0259] The total number of second reference signals associated with the first CSI report minus N;

[0260] The total number of second reference signal sets associated with the first CSI report minus N;

[0261] The total number of second reference signals indicated by the network side device minus N;

[0262] The total number of the second reference signal sets indicated by the network side device minus N;

[0263] The total number of second reference signals selected by the terminal minus N;

[0264] The total number of second reference signal sets selected by the terminal is reduced by N.

[0265] 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.

[0266] In an optional implementation, the method further includes:

[0267] 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.

[0268] In an optional implementation, the method further includes:

[0269] The network-side device receives the first CSI report fed back by the terminal.

[0270] In an optional implementation, the method further includes:

[0271] 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;

[0272] The first situation includes at least one of the following:

[0273] The most recent transmission opportunity 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;

[0274] The most recent transmission opportunity 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;

[0275] 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;

[0276] The first target operation includes at least one of the following:

[0277] Not feeding back the second CSI report;

[0278] Feedback part of the second CSI report;

[0279] Indicating in the first CSI report whether to feed back the second CSI report;

[0280] Indicate in the first CSI report whether to feed back part of the content of the second CSI report.

[0281] 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 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 instructs the terminal to feed back the second CSI report or part of the content of the second CSI report in the first CSI report, and then, based on 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, while avoiding the problem of transmission performance degradation caused by feedback of invalid information.

[0282] 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.

[0283] The second situation includes at least one of the following:

[0284] The latest 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;

[0285] The latest transmission opportunity 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;

[0286] The most recent transmission opportunity 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;

[0287] The most recent transmission opportunity 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;

[0288] 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.

[0289] The second target operation includes at least one of the following:

[0290] Not feeding back the first CSI report;

[0291] Feedback part of the first CSI report;

[0292] Indicating in the second CSI report whether to feed back the first CSI report;

[0293] Indicate in the second CSI report whether to feed back part of the content of the first CSI report.

[0294] In the above optional implementations, when the network-side device determines that the above second condition is met, in one implementation, the terminal is determined to feed back the second CSI report but not the first CSI report. In another implementation, the terminal is determined to feed back only a portion of the first CSI report. In yet another implementation, the terminal is determined to instruct the terminal in the second CSI report to feed back the first CSI report or a portion of the first CSI report, and then, based on the instruction in the second CSI report, the terminal is determined to feed back the first CSI report or a portion of the first CSI report. This can avoid or reduce repeated feedback of delay information or frequency shift information, thereby reducing terminal computational complexity. Furthermore, 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.

[0295] 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 indicates that the PMI associated with the second CSI report is calculated by the target symbol associated with the reference CSI reference resource associated with the second CSI report, and wherein the second CSI report includes multi-transmission node MTRP CSI.

[0296] 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:

[0297] 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: a most recent feedback, any feedback, and a feedback agreed upon in a protocol;

[0298] 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.

[0299] In an optional implementation, the method may further include at least one of the following:

[0300] 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:

[0301] The network-side device sends a fifteenth network signaling to the terminal, wherein the fifteenth network signaling is used to instruct to obtain the second CSI report with reference to all or part of the target information of at least one of the first CSI reports.

[0302] Through the above method provided in the embodiment of the present application, the network side device can obtain one or more types of information of delay information and frequency shift information by sending network signaling settings. 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 the terminal calculating MTRP CSI. Alternatively, it can avoid or reduce repeated feedback of delay information or frequency shift information, thereby reducing the terminal calculation complexity. Furthermore, 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.

[0303] The method for obtaining a channel state information report provided in the embodiment of the present application can be performed by a device for obtaining a channel state information report. In the embodiment of the present application, the device for obtaining a channel state information report performing the method for obtaining a channel state information report is used as an example to illustrate the device for obtaining a channel state information report provided in the embodiment of the present application.

[0304] FIG6 shows a schematic structural diagram of a device for acquiring a channel state information report according to an embodiment of the present application. As shown in FIG6 , the device mainly includes: a first determining module 601 and an acquiring module 602 .
