In some embodiments of the present disclosure, if multiple TRPs cannot be ideally synchronized, and there is no ideal backhaul link between multiple TRPs, that is, when the interaction delay between TRPs is large, it is possible to report a channel state information (CSI) report containing the arrival time difference of multiple TRPs to ensure that the data sent by multiple TPPs can reach the terminal side at the same time or within the CP range. However, when a terminal device has multiple types of CSI that need to be updated at the same time, different types of CSI each occupy a CSI processing unit (CSI processing unit, CPU), and the maximum number of CPUs supported by the terminal device at the same time is limited. When the CPUs occupied by multiple types of CSI exceed the maximum number of CPUs supported by the terminal device, multiple CSI reports cannot be updated at the same time, affecting the joint transmission performance of multiple TRPs. Therefore, how to choose which type of CSI report to update becomes a problem that needs to be solved urgently.

FIG2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. The method may be executed by the above communication system. As shown in FIG2A , the method may include:

Step S2101: The terminal device determines that the sum of the first CPU value and the second CPU value is greater than a CPU threshold.

In some embodiments, the first CPU value is the CPU required to update the first CSI report.

In some embodiments, the first CSI report may include at least one of the following:

a time difference between a first arrival time and a second arrival time, the first arrival time being an arrival time of a first reference signal on a Channel State Information Reference Signal (CSI-RS) resource, and the second arrival time being an arrival time of a second reference signal on a reference CSI-RS resource;

A frequency offset between the first reference signal and the second reference signal;

a phase offset between the first reference signal and the second reference signal;

a second parameter corresponding to the first reference signal and/or a second parameter corresponding to the second reference signal, the second parameter comprising at least one of the following: Doppler shift, Doppler spread, average delay, and delay spread;

The difference between the second parameter corresponding to the first reference signal and the second parameter corresponding to the second reference signal.

In some embodiments, the CSI-RS resource may be any CSI-RS resource except the reference CSI-RS resource among multiple CSI-RS resources sent by the network device.

In some embodiments, the terminal device may receive multiple reference signals. For example, the terminal device may receive multiple reference signals sent by a network device. For another example, the terminal device may also receive multiple reference signals sent by other entities.

In some embodiments, the first CSI report may be a CSI report generated by the terminal device after performing channel measurement based on multiple reference signals.

It should be noted that the first CSI report may also include other information specified by the protocol that can reflect the differences in reference signals corresponding to different TRPs.

In some embodiments, the first arrival time may be the time when the first reference signal arrives at the terminal device, and the second arrival time may be the time when the second reference signal arrives at the terminal device.

In some embodiments, when determining the time when a reference signal arrives at a terminal device, the impact of the time domain positions corresponding to different reference signals may be considered, or the impact of the time domain positions corresponding to the reference signals may not be considered, that is, only the arrival time differences caused by different TRP positions or different propagation paths are considered.

In one implementation, the time difference may include a time interval between a time domain position corresponding to the first reference signal and a time domain position corresponding to the second reference signal, wherein the time domain position includes at least one of the following: a time slot position and a symbol position.

For example, two CSI-RSs such as CSI-RS#1 and CSI-RS#2 have corresponding resources CSI-RS#resource 1 and CSI-RS#resource 2. The time domain position of CSI-RS#resource 1 is symbol#0 of slot#1, and the time domain position of CSI-RS#resource 2 is symbol#0 of slot#2. Assume that the terminal device measures the arrival time of CSI-RS#1 as t1 and the arrival time of CSI-RS#2 as t2. It can be understood that the time t1 is a period of time after symbol#0 of slot#1, and the time t2 is a period of time after symbol#0 of slot#2, so the time difference is t2-t1, and the time t2-t1 not only includes the time interval between symbol#0 of slot#2 and symbol#0 of slot#1, but also includes the difference in transmission time between the two reference signals sent from their respective TRPs to the terminal device.

In another implementation manner, the time difference may not include the time interval between the time domain position corresponding to the first reference signal and the time domain position corresponding to the second reference signal.

For example, two CSI-RSs such as CSI-RS#1 and CSI-RS#2 have corresponding resources CSI-RS#resource1 and CSI-RS#resource2 respectively. The time domain position of CSI-RS#resource1 is symbol#0 of slot#1, and the time domain position of CSI-RS#resource2 is symbol#0 of slot#2. Assume that the terminal device measures the arrival time of CSI-RS#1 as t1 and the arrival time of CSI-RS#2 as t2. It can be understood that the time t1 is a period of time after symbol#0 of slot#1, and the time t2 is a period of time after symbol#0 of slot#2. Therefore, the time t2-t1 not only includes the time interval between symbol#0 of slot#2 and symbol#0 of slot#1, but also includes the difference in transmission time between the two RSs sent from their respective TRPs to the terminal device. If the time difference does not include the time interval between the time domain positions corresponding to different CSI-RSs, the time difference is obtained by subtracting the time interval between symbol#0 of slot#2 and symbol#0 of slot#1 from t2-t1.

In some embodiments, the time difference may also be referred to as delay information (delay), that is, the delay of the first reference signal relative to the second reference signal reaching the terminal side.

In some embodiments, the difference between the second parameter corresponding to the first reference signal and the second parameter corresponding to the second reference signal may include at least one of the following: the difference between the Doppler frequency shift corresponding to the first reference signal and the Doppler frequency shift corresponding to the second reference signal, the difference between the Doppler spread corresponding to the first reference signal and the Doppler spread corresponding to the second reference signal, the difference between the average delay corresponding to the first reference signal and the average delay corresponding to the second reference signal, and the difference between the delay spread corresponding to the first reference signal and the delay spread corresponding to the second reference signal.

In some embodiments, the terminal device may also determine the reference CSI-RS resource.

For example, the terminal device may determine the reference CSI-RS resource before generating the first CSI report.

In some embodiments, the terminal device may receive second information sent by the network device, where the second information includes a channel measurement resource (Channel Measurement Resource, CMR), where the CMR includes at least one CSI-RS resource; and determine the reference CSI-RS resource from the at least one CSI-RS resource.

In some embodiments, the terminal device may receive the second information. For example, the terminal device may receive the second information sent by the network device. For another example, the terminal device may also receive the second information sent by other entities.

In some embodiments, the name of the second information is not limited, and may be, for example, "channel measurement resource information", "information indicating channel measurement resources", "measurement indication information", etc.

In one implementation, the terminal device may use a designated CSI-RS resource among the at least one CSI-RS resource as the reference CSI-RS resource, where the designated CSI-RS resource is the CSI-RS resource indicated by the network device or the first CSI-RS resource among the at least one CSI-RS resource.

For example, the network device may explicitly indicate the designated CSI-RS resource, and the terminal device may use the designated CSI-RS resource indicated by the network device as the reference CSI-RS resource. The network device may also implicitly indicate the designated CSI-RS resource, and "implicit indication" may be interpreted as the network device not indicating the designated CSI-RS resource, and the terminal device may use the first CSI-RS resource among at least one CSI-RS resource as the reference CSI-RS resource, and the first CSI-RS resource may be the CSI-RS resource with the smallest CSI-RS resource ID (identifier).

It should be noted that, when the network device does not indicate the designated CSI-RS resource, any CSI-RS resource among at least one CSI-RS may be used as the reference CSI-RS resource, and the any CSI-RS resource may be a CSI-RS resource specified by the protocol.

In another implementation manner, the terminal device may use the CSI-RS resource corresponding to the first CSI-RS that reaches the terminal device among the at least one CSI-RS resource as the reference CSI-RS resource.

For example, the network device may send a CSI-RS on at least one CSI-RS resource to the terminal device, and the terminal device uses the CSI-RS resource corresponding to the first received CSI-RS as the reference CSI-RS resource. In this case, the first channel state information also needs to include an identifier of the reference CSI-RS resource.

In some embodiments, the first CPU value is any one of the following:

The number of Channel State Information Reference Signal (CSI-RS) resources contained in the CMR;

The difference between the number of CSI-RS resources included in the CMR and 1;

1;

The product of a first number and a second number, the first number being the number of transceiver points TRPs, and the second number being determined according to the capability of the terminal device;

The product of a third number and the second number, the third number being the difference between the number of the TRP and 1.

For example, the first CPU value can be calculated using any of the following formulas:
O _CPU = K _S (1)
O _CPU = K _S -1 (2)
O _CPU = 1 (3)
O _CPU = X*N _TRP (4)
O _CPU =X*(N _TRP -1) (5)

Among them, O _CPU is the first CPU value, K _S is the number of CSI-RS resources included in the CMR, X is the second number, and _NTRP is the first number.

In some embodiments, the value of X may be greater than 0, for example, the value of X may be 1, 1.5, 2, 2.5, 3, etc.

In some embodiments, if the determined O _CPU is not an integer, the largest integer less than O _CPU may be used as the O _CPU (ie, rounded down). For example, if the calculated O _CPU is 2.5, the value of O _CPU may be 2.

It should be noted that the above method of determining the O _CPU is for illustration only, and the O _CPU may also be determined in other ways specified in the protocol, which is not limited in the embodiments of the present disclosure.

In some embodiments, the third number may be the number of TRPs used for CJT transmission minus one.

It should also be noted that the embodiments of the present disclosure may also determine the final O _CPU using the O _CPU calculated by the above-mentioned multiple formulas. For example, the average value calculated by the multiple formulas may be used as the O _CPU , the maximum value calculated by the multiple formulas may be used as the O _CPU , or the minimum value calculated by the multiple formulas may be used as the O _CPU . The embodiments of the present disclosure do not limit the specific determination method.

In some embodiments, the second CPU value is the CPU required to update the second CSI report.

In some embodiments, the second CSI report may be a CSI report in addition to the first CSI report.

In some embodiments, the second CSI report may include at least one of the following:

CSI-RS Resource Indicator (CSI-RS Resource Indicator, CRI) - Rank Indicator (Rank Indicator, RI) - Precoding Matrix Indicator (Precoding Matrix Indicator, PMI) - Channel Quality Indicator (Channel Quality Indicator, CQI);

CRI-RI-i1;

CRI-RI-i1-CQI;

CRI-RI-CQI;

CRI-Reference Signal Receiving Power (RSRP);

CRI-SINR;

Synchronization Signal Block (SSB) - Index - RSRP;

SSB-Index-Signal to Interference plus Noise Ratio (SINR);

CRI-RI-Layer Indicator (LI)-PMI-CQI;

CRI-RSRP-Index;

SSB-Index-RSRP-Index;

CRI-SINR-Index;

SSB-Index-SINR-Index or time domain channel properties (Time Domain Channel Properties, TDCP).

Wherein, i1 is the spatial basis vector selection indication information, which is related to the number of CSI-RS ports N1, N2, and O1 and O2. RSRP can be Layer 1 Reference Signal Receiving Power L1-RSRP (Layer 1-Reference Signal Receiving Power, L1-RSRP), and SINR can be Layer 1 Signal to Interference plus Noise Ratio L1-SINR (Layer 1-Signal to Interference plus Noise Ratio, L1-SINR). Wherein, N1 is the number of antenna ports in the first dimension, O1 is the number of oversampling or beams in the first dimension, N2 is the number of antenna ports in the second dimension, and O2 is the number of oversampling or beams in the second dimension.

It should be noted that if the second CSI report includes L1-RSRP or L1-SINR, it means that the second CSI report carries L1-RSRP or L1-SINR, that is, the content of the second CSI report is any one of the following:

CRI-RSRP;

CRI-SINR;

SSB-Index-RSRP;

SSB-Index-SINR;

CRI-RSRP-Index;

SSB-Index-RSRP-Index;

CRI-SINR-Index;

SSB-Index-SINR-Index.

If the second CSI report does not include L1-RSRP or L1-SINR, it means that the second CSI report does not carry L1-RSRP or L1-SINR, that is, the content of the second CSI report is any one of the following:

CRI-RI-i1;

CRI-RI-i1-CQI;

CRI-RI-CQI;

CRI-RI-LI-PMI-CQI;

TDCP.

It should be noted that the second CPU value can be determined according to the method specified in the existing protocol, which will not be described in detail here.

In some embodiments, the CPU threshold is determined by:

Determine a third CPU value required to update a fourth CSI report, where the fourth CSI report is a CSI report that starts to be updated before a specified symbol and needs to be continuously updated at the specified symbol, where the specified symbol is a symbol when the first CSI report and the second CSI report need to be started to be updated;

The difference between the designated CPU value and the third CPU value is used as the CPU threshold, and the designated CPU value is the CPU value that the terminal device can support.

In some embodiments, after the first CSI report is generated, the designated symbol for the next start of updating the first CSI report can be determined, and it is also determined that the second CSI report and the CPU threshold value need to be updated at the designated symbol. If there is a CSI report that has started to be updated before the designated symbol and still needs to be updated after the designated symbol (that is, there is a fourth CSI report at the designated symbol), the third CPU value required to update the fourth CSI report can be determined, and the difference between the designated CPU value (that is, the CPU value that the terminal device can support) and the third CPU value can be calculated, and the difference is used as the CPU threshold; if there is no CSI report that needs to be updated at the designated symbol (that is, there is no fourth CSI report at the designated symbol), the designated CPU value is used as the CPU threshold.

In some embodiments, the CPU threshold may also be a CPU value specified by a protocol. For example, the CPU threshold may be specified according to a CPU value that can be supported by a terminal device. This is not limited in the embodiments of the present disclosure.

In some embodiments, after determining the first CPU value and the second CPU value, if it is determined that the sum of the first CPU value and the second CPU value is greater than the CPU threshold, steps S2102 to S2104 may be executed.

Step S2102: The terminal device determines a first priority value based on the first parameter and first information of the first CSI report.

In some embodiments, the first information includes at least one of the following: reporting method, index of service cell, maximum number of service cells, report configuration identifier, maximum number of CSI report configurations; and the second priority value is determined based on the first parameter and first information of the second CSI report.

The index of the serving cell in the first information of the first CSI report may be the index of the serving cell corresponding to the first CSI report.

In some embodiments, the first priority value can be calculated by formula (1):
Pri _iCSI (y,k,c,s)＝2*N _cells *M _s *y+N _cells *M _s *k+M _s *c*s (6)

Among them, y is the reporting method of the first CSI report, k is the first parameter of the first CSI report, c is the index of the service cell corresponding to the first CSI report, N _cells is the maximum number of service cells corresponding to the first CSI report, s is the report configuration identifier of the first CSI report, _Ms is the maximum number of CSI report configurations, and "the maximum number of CSI report configurations" can be interpreted as the maximum number of CSI reports that can be configured by the terminal device.

In some embodiments, the reporting method may include any of the following:

Aperiodic CSI reports carried on the physical uplink shared channel (PUSCH);

Semi-persistent CSI reporting carried on PUSCH;

Semi-persistent CSI reporting carried on the physical uplink control channel (PUCCH);

Periodic CSI reporting carried on PUCCH.

For example, y=0 indicates aperiodic CSI reporting carried on PUSCH, y=1 indicates semi-persistent CSI reporting carried on PUSCH, y=2 indicates semi-persistent CSI reporting carried on PUCCH, and y=3 indicates periodic CSI reporting carried on PUCCH.

In some embodiments, the second CSI report carries layer 1 reference signal received power L1-RSRP (Layer 1-Reference Signal Receiving Power, L1-RSRP) or layer 1 signal to interference plus noise ratio L1-SINR (Layer 1-Signal to Interference plus Noise Ratio, L1-SINR); the second CSI report may also not carry L1-RSRP or L1-SINR.

For example, when the second CSI report carries L1-RSRP or L1-SINR, k=0; and when the second CSI report does not carry L1-RSRP or L1-SINR, k=1.

In some embodiments, N _cells may be the value of a higher layer parameter maxNrofServingCells, s may be reportConfigID, and _Ms may be the value of a higher layer parameter maxNrofCSI-ReportConfigurations.

It should be noted that, in the above-mentioned first information, only the first parameter (k) is related to the CSI report content.

In some embodiments, the first parameter of the first CSI report includes any one of the following:

The value of the first parameter of the first CSI report is less than or equal to 0;

A value of the first parameter of the first CSI report is greater than or equal to 1;

A value of the first parameter of the first CSI report is greater than or equal to 0 and less than or equal to 1;

The value of the first parameter of the second CSI report carrying L1-RSRP or L1-SINR is 0; the value of the first parameter of the second CSI report not carrying L1-RSRP or L1-SINR is 1.

For example, when the first information of the first CSI report is the same as the first information of the second CSI report, if the first parameter of the second CSI report does not carry L1-RSRP or L1-SINR, that is, the value of the first parameter of the second CSI report is 1, and the value of the first parameter of the first CSI report is less than or equal to 0, then the priority value of the first CSI report is less than the priority value of the second CSI report; if the first parameter of the second CSI report carries L1-RSRP or L1-SINR, that is, the value of the first parameter of the second CSI report is 0, and the value of the first parameter of the first CSI report is greater than or equal to 1, then the priority value of the first CSI report is greater than the priority value of the second CSI report.

Step S2103: The terminal device determines a second priority value based on the first parameter and the first information of the second CSI report.

It should be noted that the definition of the first information of the second CSI report may refer to the definition of the first information of the first CSI report, and the index of the serving cell in the first information of the second CSI report may be the index of the serving cell corresponding to the second CSI report.

In some embodiments, the second priority value can be calculated by formula (1), wherein y is the reporting method of the second CSI report, k is the first parameter of the second CSI report, c is the index of the service cell corresponding to the second CSI report, N _cells is the maximum number of service cells corresponding to the second CSI report, s is the report configuration identifier of the second CSI report, and _Ms is the maximum number of CSI report configurations.

Step S2104: The terminal device determines a third CSI report based on the first priority value and the second priority value.

In some embodiments, the third CSI report may be a CSI report with a higher priority value between the first CSI report and the second CSI report.

In some embodiments, a higher priority value indicates a lower priority, and the third CSI report may be a CSI report with a lower priority among the first CSI report and the second CSI report.

In some embodiments, if the first priority value is greater than the second priority value, the first CSI report may be used as the third CSI report; if the first priority value is less than the second priority value, the second CSI report may be used as the third CSI report.

Step S2105: The terminal device updates the fifth CSI report.

In some embodiments, the network device may receive an updated fifth CSI report and/or an unupdated third CSI report. For example, the network device may receive an updated fifth CSI report and/or an unupdated third CSI report from a terminal device. For another example, the network device may also receive an updated fifth CSI report and/or an unupdated third CSI report from another entity.

In some embodiments, the fifth CSI report may include a CSI report in addition to the third CSI report.

For example, if the first CSI report and the second CSI report have a lower priority than the first CSI report, then the third CSI report is the first CSI report, and the fifth CSI report is the second CSI report.

In some embodiments, the terminal device updates the fifth CSI report, which can be understood as the terminal device not updating the third CSI report. When the terminal device sends the CSI report, it can send at least one of the updated fifth CSI report and the unupdated third CSI report. If there is no conflict in the sending time between the updated fifth CSI report and the unupdated third CSI report, both can be sent, that is, they are sent at their respective corresponding sending times; if a conflict occurs, the unupdated third CSI report is not sent, or the updated fifth CSI report and the unupdated third CSI report are sent in a multiplexed manner at overlapping times.

By adopting the above method, when the CPU is limited, the terminal device may not update the CSI reports with low priority. In this way, it can ensure that the CSI reports with high priority can be updated in time, thereby improving the joint transmission performance of multiple TRPs.

It should be noted that the embodiment of the present disclosure does not limit the execution order of determining the first priority value and determining the second priority value in step S2102 and step S2103. The step of determining the first priority value in step S2102 can be executed first, or the step of determining the second priority value in step S2103 can be executed first.

The method involved in the embodiment of the present disclosure may include at least one of the above steps S2101 to S2105. For example, step S2101 may be implemented as an independent embodiment, step S2105 may be implemented as an independent embodiment, steps S2102+S2103 may be implemented as an independent embodiment, and steps S2104+S2105 may be implemented as an independent embodiment, but are not limited thereto.

For another example, step S2105 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

e) At least one of the Doppler frequency shift difference, Doppler spread difference, average delay difference, and delay spread difference between the RS on the CSI-RS resource and the RS on the Reference CSI-RS resource.

Embodiment 6, based on embodiment 5, the arrival time difference is defined as the time difference between two different RSs arriving at the UE side.

a) The arrival time can take into account the slot (time slot) and symbol (symbol) positions corresponding to the two RSs, that is, the arrival time should be added with the impact of the difference in slot and symbol positions corresponding to the CSI-RS resources; or,

b) The arrival time does not need to consider the slot and symbol positions corresponding to the two RSs, that is, it is assumed that the slot and symbol positions corresponding to the two RSs are the same, and only includes the arrival time difference caused by the different positions or propagation paths of the two TRPs.
