Description

Method and apparatus for sending channel state information report

This application claims the priority of the Chinese patent application with the application number 202110362501.4 and the application title "Method and Apparatus for Sending a Channel Status Information Report" filed with the China Patent Office on April 2, 2021, the entire contents of which are incorporated herein by reference Applying.

technical field

The present application relates to the field of wireless communication technologies, and in particular, to a method and apparatus for sending a channel state information report.

Background technique

In the communication process of the wireless system, before sending service data to the user equipment (UE), the network usually needs to obtain the channel state information of the downlink channel from the transmission and reception point (TRP) to the UE in advance ( channel state information, CSI). The acquisition process may be that the TRP transmits a channel state sounding signal, for example, a non-zero power channel state information reference signal (NZP CSI-RS), and the UE uses a preconfigured channel measurement resource (channel measurement resource). , CMR) to receive NZP CSI-RS for channel measurement. In addition, the network side further configures a set of interference measurement resources (interference measurement resource, IMR) corresponding to the CMR for the UE, and the UE receives signals on these pre-configured IMRs to perform interference measurement. The UE performs CSI calculation based on the measurement results on the CMR and IMR, and feeds back the CSI calculation results to the network side through the uplink channel.

Non-coherent joint transmission (NCJT) is a multi-TRP-based transmission technology introduced to improve downlink performance, that is, a maximum of two TRPs can simultaneously provide data transmission services for the same UE. Since the data sent by the two TRPs are different, the signals from the two TRPs actually interfere with each other. However, in the current communication protocol, when the UE performs CSI calculation in the NCJT mode, it is assumed that two TRPs provide services for the UE independently, regardless of the interference between the signals of the two TRPs.

In future communication protocols, if enhancement of CSI reporting is considered, the network side needs to be able to configure the UE to perform CSI calculation and reporting according to the NCJT mode. That is, when the UE performs CSI calculation, the mutual interference of the signals of the two TRPs needs to be considered.

However, CSI calculation involves a large number of matrix operations, and the computational complexity is very high, which requires a certain number of central processing units (CPUs) of the UE. After the CSI calculation in NCJT mode is introduced, the demand for the number of CPUs for CSI calculation will be further increased. According to the current communication protocol and processing rules for reporting CSI reports, when the number of idle CPUs of the UE is less than the number of CPUs required to calculate a CSI report, the UE will not update the CSI report. At the same time, the number of CPUs that can be supported by currently commercially available terminal chips is very limited (generally no more than three). Faced with the general situation that the hardware level of terminal chips is limited, it is difficult to implement the technical solution for enhancing the reporting of CSI reports. Once the number of CPUs corresponding to a CSI report exceeds the number of idle CPUs, the CSI report will not get a chance to be processed by the UE.

SUMMARY OF THE INVENTION

The present application provides a method and apparatus for sending a CSI report, which can improve the probability that the CSI report is processed by the UE.

It should be noted that the meaning of "single TRP measurement hypothesized CSI" in this application may refer to: CSI parameters are obtained from one CSI-RS resource or one CSI-RS resource and its corresponding interference measurement resource ; The meaning of "NCJT measurement hypothesized CSI" may refer to: CSI parameters are multiple CSI-RS resources in one CSI-RS resource group or multiple CSI-RS resources in one CSI-RS resource group and It is obtained on the corresponding interference measurement resource.

For the description of CSI parameters, please refer to the manual.

In a first aspect, a method for sending a CSI report is provided. It can be understood that the method can be applied to a terminal device, and can also be applied to a chip or a chip system on the terminal side. The method includes: acquiring first configuration information, where the first configuration information is used for CSI reporting, wherein the first configuration information is associated with configuration information of reference signal resources, and the configuration information of reference signal resources configures a reference signal resource set and interference measurement A resource set, the reference signal resource set includes K reference signal resources, the interference measurement resource set includes multiple interference measurement resources, and K is an integer greater than or equal to 2; determine the CSI processing unit corresponding to the CSI report. The number P, where P is a positive integer; determine the number Q of available CSI processing units, where Q is a positive integer; send an updated CSI report to the network device, where Q is less than P.

It should be noted that, the interference measurement resource set may be one or more interference measurement resource sets. For example, the interference measurement resource set is an interference measurement resource set, wherein the interference measurement resources in the interference measurement resource set are non-zero power channel state information reference signal resources (non-zero power channel state information-reference signal resource, NZP CSI-RS resource). Alternatively, the interference measurement resources in the interference measurement resource set are channel state information interference measurement resources (channel state information-interference measurement reosurce, CSI-IM resource). Alternatively, the interference measurement resource set is two interference measurement resource sets, and the types of interference measurement resources included in the two interference measurement resource sets are different. For example, the interference measurement resources in one of the two interference measurement resource sets are non-zero power channel state information reference signal resources, and the interference measurement resources in the other interference measurement resource set are channel state information interference measurement resources .

According to the rules of UE processing CSI reports in the existing communication protocol, when the number of available CSI processing units is not enough to process a CSI report, the UE abandons the update of the CSI report, that is, reports an unupdated CSI report. CSI report.

In the technical solution of the present application, for a CSI report, when the number of available CSI processing units is less than the number of CSI processing units corresponding to the CSI report, that is, the number of available CSI processing units The number is not enough to process one CSI report. The UE updates part of the CSI in the CSI report to reduce the demand for the number of CSI processing units, so as to report an updated CSI report to the network side, which is different from the existing communication protocol. The update of the CSI report, or the solution in which the CSI report cannot be processed by the UE, increases the probability that the CSI report can be processed by the UE.

In addition, after the NCJT measurement assumption is introduced into the CSI report, since the CSI calculation of the NCJT measurement assumption is compared with the CSI of the single TRP measurement assumption, the requirement for the number of CSI processing units is further increased. The number of CSI processing units corresponding to the UE processing a CSI report containing NCJT measurement assumptions is more, and according to the hardware level of the existing terminal chip, it includes no more than 4 CPUs at most, and the UE has no chance to process the CSI report containing NCJT measurement assumptions. CSI reports, this will become a common situation. The technical solution provided by this application is helpful to improve this situation. For example, when the CPU available to the UE is not sufficient to process a CSI report that contains the NCJT measurement hypothesis as well as other measurement hypotheses (eg, single TRP measurement hypothesis), the UE may only update the CSI of the NCJT measurement hypothesis, but not The other measures the assumed CSI, so that the available CPU can be sufficient to process this CSI report, thereby making this CSI report a chance to be processed by the UE.

In conjunction with the first aspect, in some implementations of the first aspect, the method further includes:

The terminal device determines S reference signal resources, where the S reference signal resources are part of the K reference signal resources included in the reference signal resource set, S is a positive integer, and S is less than K.

In this implementation manner, on the basis of configuring the K reference signal resources, the network device may further configure S reference signal resources in the K reference signal resources for single TRP measurement.

In the second aspect, a method for receiving a CSI report is provided. It can be understood that the method can be applied to a network device, and can also be applied to a chip or a chip system on the network side. The method includes: sending first configuration information to a terminal device, where the first configuration information is used for CSI reporting, wherein the first configuration information is associated with configuration information of reference signal resources, and the configuration information of reference signal resources configures a set of reference signal resources and an interference measurement resource set, the reference signal resource set includes K reference signal resources, where K is an integer greater than or equal to 2, and the interference measurement resource set includes multiple interference measurement resources; receiving an updated CSI report from the terminal equipment, The number Q of available CSI processing units of the terminal device is smaller than the number P of CSI processing units corresponding to the updated CSI report, and both P and Q are positive integers.

In the technical solution of the present application, a CSI report is configured for the UE. When the number of available CSI processing units of the UE is insufficient to process the CSI report, the UE updates part of the CSI in the CSI report to reduce the need for CSI processing. The number of units is required to report an updated CSI report to the network device.

Specifically, the third CSI processing capability value represents the number of CSI processing units corresponding to the NCJT measurement hypothesis, and the fourth CSI processing capability value represents the number of CSI processing units corresponding to the single TRP measurement hypothesis.

If Q is greater than or equal to the third CSI processing capability value, and Q is less than the fourth CSI processing capability value, it indicates that the available CSI processing units of the UE are sufficient to process the CSI assumed by the NCJT measurement but not the CSI assumed by the single TRP measurement. In this case, the UE may only update the CSI assumed by the NCJT measurement, but not the CSI assumed by the single TRP measurement.

Specifically, the fifth CSI processing capability value represents the number of CSI processing units corresponding to the single TRP measurement hypothesis, and the sixth CSI processing capability value represents the number of CSI processing units corresponding to the NCJT measurement hypothesis.

If Q is greater than or equal to the fifth CSI processing capability value, and Q is less than the sixth CSI processing capability value, it indicates that the available CSI processing units of the UE are sufficient to process the CSI assumed by the single TRP measurement but not the CSI assumed by the NCJT measurement. In this case, the UE may only update the CSI assumed by the single TRP measurement, but not the CSI assumed by the NCJT measurement.

Equipment, etc., are not limited.

The technical solutions of the present application are described herein by taking TRP and UE as examples.

Referring to FIG. 1 , FIG. 1 is a schematic diagram of a communication system applicable to this embodiment of the present application. As shown in FIG. 1 , the wireless communication system 100 includes at least two network devices, such as TRP 111 and TRP 112 as shown in FIG. 1 . The wireless communication system 100 may further include a terminal device, such as the terminal device 113 shown in FIG. 1 . Among them, TRP 111 and TRP 112 can provide data transmission service for terminal device 113 at the same time.

Optionally, when the TRP 111 and the TRP 112 provide services for the terminal device 113 at the same time, two different implementation modes may be included, namely, a mode based on multiple downlink control information (DCI) and a mode based on a single DCI.

In the multi-DCI mode, the TRP 111 and the TRP 112 each transmit one DCI, and schedule two physical layer downlink shared channels (physical downlink share channels, PDSCH) to be sent to the terminal device 113. Among them, one DCI schedules one PDSCH. In the single DCI mode, only one TRP in TRP 111 and TRP 112 transmits 1 DCI and schedules 1 PDSCH. However, some of the streams or layers in this PDSCH are transmitted by one TRP, and another part of the streams or layers are transmitted by another TRP. Among them, some of the streams or layers correspond to some of the demodulation reference signal (demodulation reference signal, DMRS) ports.

When the TRP 111 and the TRP 112 provide data transmission services for the terminal device 113 at the same time, the transmission mode at this time is called a non-coherent joint transmission (NCJT) mode.

In order to facilitate the understanding of the solution, the following briefly introduces the CSI measurement based on multiple TRPs, that is, the CSI measurement in the NCJT mode.

For CSI measurement in NCJT mode, the network side first transmits a channel state sounding signal, for example, NZP CSI-RS is used in the new radio interface (new radio, NR). The UE receives the NZP CSI-RS on a preconfigured channel measurement resource (channel measurement resource, CMR) for channel estimation. In addition, the network side also configures a set of interference measurement resources (interference measurement resource, IMR) corresponding to the CMR for the UE, and the UE receives signals on these pre-configured IMRs to perform interference measurement. Based on the measurement results of the CMR and IMR, the CSI is calculated, and finally the CSI is fed back to the network side through the uplink channel. The network side sends service data to the UE based on the NCJT mode according to the CSI report fed back by the UE.

In NCJT mode, although the data sent by the two TRPs is for the same UE, the data sent by the two TRPs (for example, in the multi-DCI mode, are carried by two PDSCHs, and in the single-DCI mode, they are carried by two groups of stream or layer bearer) are different, so the signals from the two TRPs actually interfere with each other. When the UE receives the signal from TRP1, the signal from TRP2 may interfere with the reception of the signal from TRP1, and vice versa. However, in the current communication protocol, when the UE performs CSI measurement, it is assumed that the TRPs serve the UE independently, and the interference between the signals of the two TRPs when the two TRPs serve the same UE at the same time is not considered.

When the UE performs CSI measurement, if the measurement is based on the assumption that a single TRP provides services for the UE alone, it is hereinafter referred to as a single TRP measurement assumption. The CSI parameter is obtained by measurement on a specific reference signal resource configured on the network side and its associated interference measurement resource, and is hereinafter referred to as the CSI assumed by the single TRP measurement. The reference signal resource set associated with the CSI report includes at least one reference signal resource, which is hereinafter referred to as a CSI report including a single TRP measurement hypothesis. However, if the interference between the signals of the two TRPs is considered, it is the NCJT measurement hypothesis. The reference signal resource set associated with the CSI report includes at least one reference signal resource group, which is hereinafter referred to as a CSI report including NCJT measurement assumptions.

It is understandable that, for terminal equipment, CSI calculation involves various matrix operations, and the computational complexity and computational complexity are very high, which has a very high impact on the chip cost and power consumption of the terminal equipment. In addition, terminal devices using chips with different capabilities have different capabilities for calculating CSI.

When the network device configures or triggers the UE to perform reporting of the CSI report, the UE will occupy a certain amount of CPU resources (represented by O _CPU below). For different measurement configurations, the number of CPUs occupied by the CSI report calculation is also different. For example, when the network side configures the UE to perform time-frequency offset tracking measurement, the calculation of the CSI report will occupy no CPU, that is, O _CPU = 0; and if the CSI report is used for beam measurement, the calculation of the CSI report will occupy 1 CPU, that is, 0 _CPU = 1; if the UE is configured to report the CSI report quickly, the calculation of the CSI report will occupy all CPU, 0 _CPU = N _CPU ; if the UE is configured to report the regular non-beam, non-time-frequency tracking, non-fast CSI report , the calculation of the CSI report will occupy K _S CPUs, where K _S represents the number of NZP CSI-RS resources used for channel measurement associated with the CSI report.

Calculate the number of CPUs occupied by the CSI report or CSI, which is hereinafter referred to as the number of CPUs corresponding to the CSI report or CSI.

According to the current communication protocol, such as version 15 (release 15, R15) or version 16 (release 16, R16), the CSI report processing rules specified, when the number of available CPUs is less than the number of CPUs corresponding to a CSI report , the UE will not update the CSI report, and on the time-frequency resource used for sending the CSI report, the UE sends an unupdated CSI report.

At the same time, in the current commercial chips, the number of CPUs of the terminal equipment is very limited. In the current commercial chips, there are usually only 2 and at most 4 CPUs. Under this situation, once the number of CPUs corresponding to one CSI report exceeds the number of CPUs currently idle in the UE, the UE will not report the updated CSI report to the network side.

To this end, the present application provides a method for sending CSI, which can improve the probability that a CSI report is processed by a terminal device. Even if the number of CPUs corresponding to a CSI report is greater than the number of CPUs available to the UE, the UE still It is possible to update this CSI report so as to report the updated CSI to the network side. The so-called number of available CPUs here refers to: on a symbol, the calculation of multiple CSI reports needs to start occupying the CPU. For CSI report n, the number of available CPUs is:

Among them, N _CPU represents the number of CPUs that the terminal device can support at the same time, L represents the number of CPUs that have been occupied, and O _i represents the number of CPUs corresponding to CSI report i, where the priority of x CSI reports is higher than that of CSI reports n The priority of , that is, there are x CSI reports with a priority higher than CSI report n, where the number of CPUs corresponding to the i-th CSI report is represented as O _i . The CSI report priority is determined according to the configuration parameters related to the CSI report, for example, the type of the CSI report, the content of the CSI report, and the configuration ID of the CSI report, and the like.

In general, in the technical solution of the present application, when the number of CPUs corresponding to one CSI report calculated is greater than the number of CPUs currently available to the UE, the UE can update part of the CSI in the CSI report, and send the updated CSI report to the network side, that is, the UE sends an updated CSI report to the network side.

Further, in a multi-TRP scenario, considering that the single TRP measurement assumption ignores the defect of interference between signals of different TRPs, the future communication system may enhance the CSI report, so that the network side can configure the UE to perform CSI in the NCJT mode. Calculation and reporting. It will generally occur that the number of CPUs corresponding to the CSI report that includes the NCJT measurement assumption is larger than the number of CPUs available to the UE. With the technical solution of the present application, the UE can only update the NCJT included in the CSI report. The assumed CSI is measured, but the CSI assumed for single TRP measurement is not updated, so that the number of CPUs corresponding to the calculation of the CSI report can also be reduced, so that the CSI containing the NCJT measurement assumption is more likely to be processed by the UE, and the The processing results are fed back to the network side to improve the limited hardware level to a certain extent.

The technical solution of the present application will be described in detail below.

In this application, the complexity of the CSI calculation of the NCJT measurement hypothesis is higher than that of the single TRP measurement hypothesis, and the NCJT measurement hypothesis is only an example of a measurement hypothesis with higher complexity (relative to the single TRP measurement hypothesis) . For example, with the evolution of communication technologies, in future communication systems, calculating a CSI report may also include other measurement assumptions than the single TRP measurement assumption and the NCJT measurement assumption, if the CSI calculation under the other measurement assumptions is expected by the network side, then in the case that the number of available CPUs of the UE cannot satisfy the CSI for calculating all the measurement assumptions in the CSI report, the technical solutions of the present application are still applicable, that is, the UE can choose to update only the expected CSI The calculation result of the assumed CSI is measured and reported to the network side.

The following description only takes the assumption that the CSI report involves the NCJT measurement and the single TRP measurement assumption as an example.

Referring to FIG. 2, FIG. 2 is a flowchart of a method for sending a CSI report provided by the present application. The method in FIG. 2 may be executed by a communication device, or may be executed by a chip installed in the communication device. The following describes the method 200 executed by a communication device (specifically, a network device and a terminal device) as an example.

In addition, the numbers 210-250 in FIG. 2 are only for clearly describing the solution. In a specific implementation, the steps 210-250 can be combined into fewer steps or split into more steps, or can also be increased some other steps. This article does not limit this. In addition, the above steps 210-250 are only used for the purpose of differentiation, and do not represent the order of execution of the steps.

210. The network device sends first configuration information to the terminal device, where the first configuration information is used for CSI reporting. The terminal device obtains the first configuration information.

The first configuration information is associated with configuration information of reference signal resources, the configuration information of reference signal resources configures a reference signal resource set and an interference measurement resource set, the reference signal resource set includes K reference signal resources, and K is greater than or An integer equal to 2, the set of interference measurement resources includes a plurality of interference measurement resources.

Optionally, the set of interference measurement resources may be one or more.

For example, the interference measurement resource set is an interference measurement resource set, and the interference measurement resource in the interference measurement resource set may be an NZP CSI-RS resource or a CSI-IM resource.

For another example, the interference measurement resource set is two interference measurement resource sets, and the types of interference measurement resources included in the two interference measurement resource sets are different. For example, the interference measurement resources in one of the two interference measurement resource sets are non-zero power channel state information reference signal resources, and the interference measurement resources in the other interference measurement resource set are channel state information interference measurement resources .

The configuration information of the reference signal resources may be used by the terminal device to determine one or more reference signal resource groups, wherein each reference signal resource group includes multiple reference signal resources, and each reference signal resource group includes multiple reference signal resources The resources all belong to the same reference signal resource set. The reference signal resource may be a non-zero power channel state information reference signal resource (non-zero power channel state information-reference signal resource, NZP CSI-RS resource). The reference signal resources are resources used for channel measurement.

Optionally, the configuration information of the reference signal resources can also be used by the terminal device to determine S reference signal resources from the K reference signal resources, where S is less than K, and S is a positive integer.

The configuration information of the reference signal resources may also be associated with one measurement resource set, the measurement resource set includes multiple interference measurement resources, and the interference measurement resources may be non-zero power channel state information reference signal resources (non-zero power channel resources). state information-reference signal resource, NZP CSI-RS resource), or may be channel state information-interference measurement resource (channel state information-interference measurement reosurce, CSI-IM resource).

The terminal equipment can obtain multi-user interference based on NZP CSI-RS resource; or can obtain inter-cell interference based on CSI-IM resource. Each reference signal resource is associated with one interference measurement resource in the one measurement resource set, and each reference signal resource group is associated with one or two interference measurement resources in the one measurement resource set relation.

The terminal device receives indication information of the network device, where the indication information indicates the association relationship between the reference signal resources and reference signal resource groups in the reference signal resource set and the interference resources in the measurement resource set. Alternatively, the terminal device determines the association relationship between the reference signal resources and reference signal resource groups in the reference signal resource set and the interference resources in the measurement resource set according to a predefined rule.

The following is a specific example of determining the reference signal resource and the association relationship between the reference signal group and the interference resource according to a predefined rule. The reference signal resource set includes 4 reference signal resources and 2 reference signal resource groups (wherein the reference signal resource group may be explicitly included or implicitly included), and the measurement resource set associated with the reference signal resource set Contains 6 interference measurement resources. which is:

Reference signal resource set: {reference signal resource 1, reference signal resource 2, reference signal resource 3, reference signal resource 4, reference signal resource group 1, reference signal resource group 2};

Measurement resource set: {interference measurement resource 1, interference measurement resource 2, interference measurement resource 3, interference measurement resource 4, interference measurement resource 5, interference measurement resource 6};

The pre-defined rule may be that the reference signal resources in the reference signal resource set are associated with a corresponding number of interference measurement resources in the measurement resource set in order, and the reference signal resource group in the reference signal resource set is associated with the remaining interference in the measurement resource set. The measurement resources are sequentially associated with one interference measurement resource. According to the above rules, the reference signal resource/reference signal resource group and the interference measurement resource with an associated relationship can be expressed as:

{reference signal resource 1, interference measurement resource 1}, {reference signal resource 2, interference measurement resource 2}, {reference signal resource 3, interference measurement resource 3}, {reference signal resource 4, interference measurement resource 4}, {ref Signal resource group 1, interference measurement resource 5}, {reference signal resource group 2, interference measurement resource 6}. Wherein, the reference signal resource/reference signal resource group in the curly brackets has an associated relationship with the interference measurement resource.

Alternatively, the configuration information of the reference signal resources may also be associated with two other measurement resource sets, the first measurement resource set includes multiple channel state information interference measurement resources, and the second measurement resource set includes multiple non-zero power Channel state information reference signal resources. Each of the reference signal resources has an associated relationship with one interference measurement resource in the first measurement resource set, and has an associated relationship with one interference measurement resource in the second measurement resource set; and each The reference signal resource group is associated with one or two interference measurement resources in the first measurement resource set, and is associated with one or two interference measurement resources in the second measurement resource set relation.

The CSI under the single TRP measurement assumption is calculated on the reference signal resource and its associated interference measurement resource; the CSI under the NCJT measurement assumption is the multiple reference signal resources included in the reference signal resource group and their associated interference measurement resources. Calculated on the associated interference measurement resource.

The CSI under the single TRP measurement assumption includes many parameters.

For example, it includes 1 channel state information reference signal resource indicator (CSI-RS resource indicator, CRI); 1 rank indicator (rank indicator, RI) information to indicate the rank value; 1 channel quality indicator (channel quality indicator) , CQI) information to indicate channel quality; 1 precoding matrix indicator (PMI) information to indicate precoding matrix information; 1 layer indicator (LI) information to indicate layer information. Alternatively, one piece of CRI information, one piece of RI information, and one piece of CQI information may also be included; or, one piece of CRI information, one piece of RI information, one piece of CQI information, and one piece of PMI information may also be included.

Any one of the above parameters may also be referred to as a CSI parameter.

The CRI information included in the CSI under the single TRP measurement assumption is associated with a reference signal resource. Except for the CRI itself, other CSI parameters in the CSI report are in the reference signal resource associated with the CRI and the reference signal resource. Calculated on the interference measurement resource associated with the reference signal resource. The parameters specifically included in the CSI under the single TRP measurement assumption are configured by the network side.

The CSI under the NCJT measurement assumption includes many parameters.

For example, it includes 1 piece of CRI information, 2 pieces of RI information and 1 piece of CQI information; 2 pieces of PMI information; and 2 pieces of LI information. Or, it includes 1 piece of CRI information, 2 pieces of RI information and 1 piece of CQI information. Alternatively, one piece of CRI information, two pieces of RI information, one piece of CQI information, and two pieces of PMI information may be included.

Any one of the above parameters may also be referred to as a CSI parameter.

The CRI information included in the CSI under the NCJT measurement assumption is associated with a reference signal resource group. Except for the CRI itself, other CSI parameters in the CSI report are in the reference signal resource group associated with the CRI and the reference signal resource group. Calculated on the interference measurement resources associated with the reference signal resource group. The specific parameters included are configured by the network side.

Exemplarily, the first configuration information may be denoted as CSI-MeasConfig, where the CSI-MeasConfig may include a CSI-ResourceConfig field and a CSI-ReportConfig field. That is, the first configuration information mainly includes information for configuring CSI-RS resources (that is, the above-mentioned configuration information of CSI-RS resources), and information for configuring CSI reports.

The configuration information of the reference signal resources is used to configure a reference signal resource set, that is, a CSI-RS-ResourceSet. The CSI-RS-ResourceSet includes the most basic CSI-RS resource. Wherein, the CSI-RS resource may include a non-zero power channel state information reference signal (non-zero power channel state information reference signal, NZP CSI-RS). Further, the types of these CSI-RS resources may be periodic, aperiodic or semi-persistent.

In addition, the CSI-ReportConfig field is used to configure how the UE reports CSI reports.

Exemplarily, the CSI-ReportConfig may include two aspects of CSI-ResourceConfigId and reportConfigType. The CSI-ResourceConfigId is used to associate with the CSI-ResourceConfig, and the UE can obtain CSI-RS resources for measurement. reportConfigType is used to configure the type of CSI report to be periodic, aperiodic or semi-persistent, wherein the semi-persistent CSI report includes a physical uplink control channel (PUCCH) or a physical uplink shared channel (physical uplink shared channel). channel, PUSCH) for reporting.

In this application, since the CSI measurement needs to be differentiated based on the single TRP measurement assumption or the NCJT measurement assumption, the network device may perform the following configurations:

The network device may configure K reference signal resources for channel measurement for the terminal device, and the network device may further configure N reference signal resource groups in the K reference signal resources, and each reference signal resource group contains 2 reference signal resources. signal resource. From a configuration point of view, the two reference signal resources included in the same reference signal resource group are associated with two different transmission configuration indicator states (TCI state) information, and the TCI state contains the information of the reference signal resource. Quasi co-location (QCL) information. The terminal device receives the reference signal on the corresponding reference signal resource according to the QCL information contained in the TCI state. The UE performs CSI calculation on the 2 reference signal resources included in each reference signal resource group and the associated interference measurement resources according to the NCJT measurement assumption. Therefore, when N reference signal resource groups are configured, it means that there are N NCJTs Measurement assumptions. In addition, the network device can configure the terminal device to perform CSI calculation on the K reference resource resources and the associated interference measurement resources according to the single TRP measurement hypothesis, that is, there are K single TRP measurement hypotheses and N NCJT measurement hypotheses.

Optionally, the network device may further configure S reference signal resources among the K reference signal resources for CSI calculation of a single TRP measurement hypothesis, that is, there are S single TRP measurement hypotheses and N NCJT measurement hypotheses, Among them, S is a positive integer, and S is less than K.

It can be understood that it is only an optional solution that the network device further configures S reference signal resources for the CSI calculation of the single TRP measurement hypothesis, and the network side can only configure the K reference signal resources and the N reference signal resources. In this case, by default, all the K reference signal resources can be used for CSI calculation of a single TRP measurement hypothesis.

In order to match the calculation of CSI for the single TRP measurement assumption and the NCJT measurement assumption, the network device may configure the UE to include in a CSI report:

Option 1: X CSI assumed for single TRP measurement and 1 CSI assumed for NCJT measurement, where X can be 0, 1, 2;

Option 2: 1 CSI, where this CSI can be obtained by measurement under 1 measurement assumption among all single TRP measurement assumptions and NCJT measurement assumptions.

When the UE is configured to perform CSI reporting according to option 1, and X=0, the terminal device needs to report a CSI assumed by the NCJT measurement. In this case, the CSI report only includes the CSI assumed by the NCJT measurement. When X=1 or X=2, the UE needs to report the CSI of the single TRP measurement assumption and the CSI of the NCJT measurement assumption. At this time, the CSI report includes both the NCJT measurement assumption and the single TRP measurement assumption. When the terminal device is configured to perform CSI reporting according to option 1, the terminal device reports a CSI report that includes the CSI calculation result of a certain measurement hypothesis. At this time, the CSI report also includes only one measurement hypothesis (single TRP measurement hypothesis or NCJT measurement assumptions).

From this, it can be understood that the CSI report mentioned in this document contains a single TRP measurement assumption, or the CSI report contains a single TRP measurement assumption and an NCJT measurement assumption, or the CSI report contains an NCJT measurement assumption, or the CSI report contains two measurement assumptions, or the CSI report It contains one or some measurement assumptions, which will not be repeated below.

220. The terminal device determines one or more reference signal resource groups.

Wherein, each reference signal resource group includes multiple reference signal resources, and the multiple reference signals included in each reference signal resource group belong to the above-mentioned reference signal resource set.

The terminal device may determine one or more reference signal resource groups based on the indication information sent by the network device. For example, each reference signal resource group includes 2 reference signal resources, and the K reference signal resources included in the reference signal resource set are divided into 2 reference signal resource subsets, which are subset 1 and subset 2 respectively. Wherein, subset 1 includes K ₁ reference signal resources, and subset 2 includes K ₂ reference signal resources. The terminal device receives 1 indication information, for example, the indication information is a bit sequence of length K ₁ K ₂ , and the (i-1) K ₂ +jth bit corresponds to the ith reference signal resource in subset 1 and the ith reference signal resource in subset 2. A reference signal resource group formed by the jth reference signal resource, where i is a positive integer less than or equal to K ₁ , and j is a positive integer less than or equal to K ₂ . When the (i-1)K ₂ +jth bit is "1", the corresponding reference signal resource group is a reference signal resource group configured for the terminal device; if the (i-1)K ₂ +jth bit is When "0", the corresponding reference signal resource group is not a reference signal resource group configured for the terminal device. The total number of "1" bits in the bit sequence of length K ₁ K ₂ determines the number of reference signal resource groups. The bits "1" and "0" are only examples, and vice versa, that is, when the (i-1)K ₂ +jth bit is "0", the corresponding reference signal resource group is a reference configured to the terminal device Signal resource group; if the (i-1)K ₂ +jth bit is "1", the corresponding reference signal resource group is not a reference signal resource group configured for the terminal device. The total number of "0" bits in the bit sequence of length K ₁ K ₂ determines the number of reference signal resource groups.

Alternatively, the terminal device determines one or more reference signal resource groups according to a preset rule. For example, each reference signal resource group includes 2 reference signal resources, and the K reference signal resources included in the reference signal resource set are divided into 2 reference signal resource subsets, which are subset 1 and subset 2 respectively. Subset 1 includes K ₁ reference signal resources, subset 2 includes K ₂ reference signal resources, K ₁ ≤ K ₂ , K 1 reference signal resources in subset ₁ and the first K ₁ reference signal resources in subset 2 The signal resources are sequentially associated to form K ₁ reference signal resource groups, that is, the ith reference signal resource in subset 1 is associated with the ith reference signal resource in subset 2 to form one reference signal resource group.

230. The terminal device determines the number P of CSI processing units corresponding to the CSI report, where P is a positive integer.

According to the description in 210, it can be understood that when the CSI report includes both the single TRP measurement hypothesis CSI and the NCJT measurement hypothesis CSI, in step 230, the number of CSI processing units corresponding to the CSI report is the single TRP measurement hypothesis The CSI and NCJT measurements assume the sum of the number of CSI processing units corresponding to each CSI. When the CSI report contains only one measurement hypothesis CSI (single TRP measurement hypothesis CSI or NCJT measurement hypothesis CSI), the number P of CSI processing units corresponding to the CSI report is the CSI calculation of the measurement hypothesis included in the CSI report. The number of corresponding CSI processing units.

Exemplarily, the CSI processing unit may be a CPU.

240. The terminal device determines the number Q of available CSI processing units, where Q is a positive integer.

In a time unit (eg, symbol), the computation of multiple CSI reports needs to start occupying the CPU, and for CSI report n, the number of available CPUs is

Among them, N _CPU represents the number of CPUs that the terminal device can support at the same time, L represents the number of occupied CPUs, O _i represents the number of CPUs corresponding to CSI report i, where x CSI reports have a higher priority than The priority of the CSI report n.

250. The terminal device sends an updated CSI report to the network device, where Q is less than P. The network device receives the updated CSI report from the network device.

That is, when Q is less than P, the terminal device sends an updated CSI report to the network device.

It should be noted that when Q is greater than or equal to P, the terminal device also sends an updated CSI report to the network device.

That is to say, for a CSI report, if the CSI report contains two or more measurement hypotheses, in the case where Q is less than P, the CSI report sent by the terminal device to the network device only contains part of the updated CSI . When Q is equal to or greater than P, the CSI report sent by the terminal device to the network device may include all the updated CSI.

In this document, the updated CSI report may refer to, with respect to a CSI report configured by the network side for the UE, the UE performs the calculation of part or all of the CSI contained in the CSI report according to the configuration of the network side, and uses the CSI report to calculate the CSI report. The calculation result of is carried in the CSI report. In other words, an updated CSI report includes at least part of the updated CSI, and the updated CSI is relative to the unupdated CSI. Exemplarily, the unupdated CSI means that the UE has not performed the calculation of the CSI, and the calculation result of the existing CSI obtained from the cache may be carried in the CSI report, or any data generated may be carried in the CSI report.

The updated CSI report described in step 250 will be described in detail below in conjunction with the calculation of CSI for different measurement assumptions involved in this application.

In order to clearly describe the solution, the reference signal resource group and the reference signal resource it contains, or the reference signal indication information, or the CSI measurement information, under different possible situations (see (1)-(6) above), or The CSI measurement result information and the like are distinguished by the numbers "first", "second", "'third'", and so on.

Several examples of the UE sending the updated CSI report to the network side when Q is less than P are described above. Further, in the case that Q is smaller than P, various possible specific implementations are involved.

For example, as an example, Q is less than P, and Q is greater than or equal to a first CSI processing capability value, and the first CSI processing capability value is associated with the number N of the one or more reference signal resource groups determined by the UE.

Exemplarily, the first CSI processing capability value may represent the number of CSI processing units corresponding to the CSI calculation performed by the UE with a complexity higher than that assumed for a single TRP measurement.

Taking the single TRP measurement hypothesis and the NCJT measurement hypothesis as an example, the CSI calculation of the NCJT measurement hypothesis requires joint CSI calculation on two reference signal resources and their corresponding interference measurement resources to obtain one set of CSI measurement information, and its complexity is average. It is higher than performing CSI calculation separately on the two reference signal resources and their corresponding interference measurement resources to obtain two sets of CSI measurement resources. In this case, the first CSI processing capability value may be the number of CSI processing units corresponding to the CSI calculation assumed by the NCJT measurement.

Preferably, the first CSI processing capability value is equal to 2 times N. In addition, the first CSI processing capability value may also have other associated relationships with N, for example, the first CSI processing capability value is equal to three times N, etc., which are not limited.

For another example, in another example, Q is less than P, and Q is greater than or equal to a second CSI processing capability value, and the second CSI processing capability value is associated with the number K of the CSI-RS resources.

Similar to the above-mentioned first CS processing capability value, the second CSI processing capability value may represent the number of CSI processing units corresponding to the CSI calculation assumed by the UE to perform a single TRP measurement.

Preferably, the second CSI processing capability value is equal to K.

As another example, in another example, Q is less than P, and Q is greater than or equal to the third CSI processing capability value, and Q is less than the fourth CSI processing capability value. The third CSI processing capability value is associated with the number N of the one or more reference signal resource groups, and the fourth CSI processing capability value is associated with the number K of the CSI-RS resources.

Here, for the meaning of the third CSI processing capability value, reference may be made to the first CSI processing capability value, and for the meaning of the fourth CSI processing capability value, reference may be made to the description of the second CSI processing capability value, which will not be repeated.

As another example, in another example, Q is less than P, and Q is greater than or equal to the fifth CSI processing capability value, and Q is less than the sixth CSI processing capability value. The fifth CSI processing capability value is associated with the number N of the one or more reference signal resource groups, and the sixth CSI processing capability value is associated with the number K of the CSI-RS resources.

Here, for the meaning of the fifth CSI processing capability value, reference may be made to the first CSI processing capability value, and for the meaning of the sixth CSI processing capability value, reference may be made to the description of the second CSI processing capability value, which will not be repeated.

Optionally, in the above embodiment, P is associated with the determined number N of the one or more reference signal resource groups. For example, for multiple CSI reports that need to occupy one symbol, and the multiple CSI reports contain only one measurement hypothesis (as in case 1 below), for the nth CSI report, if the UE is configured to use option 1 for report, and X is configured as 0, then P is equal to a times N. Or in case 1, and X is configured as 1 or 2, then P is equal to aN+ _Ks . Alternatively, at least one of the multiple CSI reports includes two measurement hypotheses, (as in case 2 below), and P is equal to aN+K _s . Where a is a number greater than 1, for example, a is 2, or a is 3, etc.

The following takes the single TRP measurement assumption and the NCJT measurement assumption as examples to give how the UE reports the CSI report in many specific cases where Q is less than P.

In order to facilitate the description below, the following conventions are first made:

The UE reports to the network side the number of parallel CSI calculations that can be supported (hereinafter defined as N _CPU ). The UE receives the first configuration information from the network side, and obtains the CSI report configuration from the first configuration information. In a given time unit, the number of idle CSI processing units of the UE is N _CPU -L.

In a given time unit, the UE has N CSI reports that need to occupy idle CSI processing units. Here, the time unit may be a time slot or an OFDM symbol, etc., which is not particularly limited.

When the number of CSI processing units corresponding to the N CSI reports is greater than the number of idle CSI processing units, that is, the

in,

Indicates the number of CPUs corresponding to the nth CSI report in the N CSI reports. According to the technical solutions provided in this application, the UE can perform the CSI report in the following manner.

The UE reports the CSI reports according to the types of the N CSI reports. Specifically, the types of the N CSI reports may refer to the types of measurement assumptions included in the N CSI reports. According to whether there is a CSI report containing both the single TRP measurement hypothesis and the NCJT measurement hypothesis in the N CSI reports, it can be divided into the following case 1 and case 2.

Case 1

Each of the N CSI reports has only one of the single TRP measurement hypothesis and the NCJT measurement hypothesis, that is, each CSI report contains only one measurement hypothesis.

For example, if the network side configures the UE to perform CSI reporting according to option 1, and configures X=0, then only NCJT measurement assumptions exist in the CSI report.

When performing CSI reporting, the UE only needs to send M updated CSI reports to the network side, and does not need to update the remaining NM CSI reports. Among them, the M updated CSI reports have a higher priority than the remaining NM CSI reports, and M is the maximum value when the total number of occupied CPUs is not greater than the number of idle CPUs, that is, it satisfies

Case 2

At least one of the N CSI reports includes both a single TRP measurement hypothesis and an NCJT measurement hypothesis.

For the clarity and conciseness of the description, the number of CPUs corresponding to the CSI report that includes both the single TRP measurement hypothesis and the NCJT measurement hypothesis will be expressed as

in,

Indicates the number of CPUs corresponding to the CSI report assumed by a single TRP measurement,

Indicates the number of CPUs corresponding to the CSI report assumed by the NCJT measurement.

When performing CSI reporting, the UE determines whether the corresponding CSI reports need to be updated in order according to the priorities of the N CSI reports and in descending priority order. Number of CPUs available for the nth CSI report

for:

Here, the 1st, 2nd, 3rd,...n-1th CSI reports have higher priority than the nth CSI reports. When the number of available CPUs is less than the number of CPUs corresponding to the nth CSI report

Whereas the nth CSI report includes both the NCJT measurement hypothesis and the single TRP measurement hypothesis, the UE may only update the CSI of part of the measurement hypotheses in the n CSI reports.

Exemplarily, the UE may report the CSI in the following manner.

way 1

Optionally, in Mode 1, the UE is based on the number of available CPUs and

, determine the CSI that needs to be updated in the nth CSI report.

As an example, the determination process is as follows:

(1) If the number of available CPUs is less than the number of CPUs corresponding to the CSI assumed by the NCJT measurement, that is, the number of available CPUs is less than

The UE does not update the CSI information in the nth CSI report, that is, the UE does not update the CSI assumed by the NCJT measurement and the CSI assumed by the single TRP measurement.

(2) If the number of available CPUs is greater than or equal to the number of CPUs corresponding to the CSI assumed by the NCJT measurement, that is, the number of available CPUs is greater than or equal to

Then, in the nth CSI report, the UE only updates the CSI assumed by the NCJT measurement, but does not update the CSI assumed by the single TRP measurement.

Specifically, if the UE is configured to use option 1 to send the nth CSI report, that is, the UE needs to report X CSI for single TRP measurement assumptions and 1 CSI for NCJT measurement assumptions. At this time, the UE only measures the CSI assumed by the NCJT measurement, and updates the CSI assumed by the NCJT measurement in the nth CSI report, and the CSI assumed by the single TRP measurement that is not updated.

It should be noted that when the UE does not need to update the CSI of the single TRP measurement hypothesis, the UE does not need to perform the CSI calculation according to the single TRP measurement hypothesis. At this time, the number of CPUs corresponding to the nth CSI report is

If the UE is configured to use option 2 to send the nth CSI report, the UE only needs to report 1 CSI, which is obtained by measurement under one NCJT measurement hypothesis among all the NCJT measurement hypotheses included in the nth CSI report .

Likewise, it should be noted that when the UE is configured to use option 2 to send the nth CSI report, although the nth CSI report is associated with multiple reference signal resources for single TRP measurement hypotheses, and reference signal resources for multiple NCJT measurement hypotheses Since the UE needs to measure on the reference signal resource group corresponding to all NCJT measurement hypotheses, and obtain updated CSI on the reference signal resource group corresponding to 1 NCJT measurement hypothesis, it does not need to be on the reference signal resource. The CSI calculation is performed according to the single TRP assumption. Therefore, the number of CPUs corresponding to the nth CSI report is equal to

way 2

Optionally, in Mode 2, the UE is based on the number of available CPUs,

and

The size comparison relationship of , determines the CSI that needs to be updated in the nth CSI report.

As an example, the determination process is as follows:

(1) If the number of available CPUs is greater than or equal to the number of CPUs corresponding to the CSI assumed by the NCJT measurement, and less than the number of CPUs corresponding to the CSI assumed by the single TRP measurement, that is, the number of available CPUs less than

Also, the number of available CPUs is less than

The UE needs to update the CSI of the NCJT measurement assumption in the nth CSI report.

(2) If the number of available CPUs is less than the number of CPUs corresponding to the CSI assumed by the NCJT measurement, and greater than or equal to the number of CPUs corresponding to the CSI assumed by the single TRP measurement, that is, the number of available CPUs less than

Also, the number of available CPUs is greater than or equal to

The UE needs to update the CSI of the single TRP measurement assumption in the nth CSI report.

(3) If the number of available CPUs is greater than the number of CPUs corresponding to the CSI assumed by the NCJT measurement, and greater than the number of CPUs corresponding to the CSI assumed by the single TRP measurement, that is, the number of available CPUs is greater than

Also, the number of available CPUs is greater than

The UE can adopt the following reporting schemes:

As some examples, the UE makes the following updates in the nth CSI report.

Specifically, if the number of CPUs corresponding to the NCJT measurement hypothesis is greater than the number of CPUs corresponding to the CSI of the single TRP measurement hypothesis, the UE updates the CSI of the NCJT measurement hypothesis in the nth CSI report.

Alternatively, if the number of CPUs corresponding to the single TRP measurement hypothesis is greater than the number of CPUs corresponding to the CSI of the NCJT measurement hypothesis, the UE updates the CSI of the single TRP measurement hypothesis in the nth CSI report.

Alternatively, if the number of CPUs corresponding to the single TRP measurement hypothesis is equal to the number of CPUs corresponding to the CSI of the NCJT measurement hypothesis, the UE updates the CSI of the NCJT measurement hypothesis in the nth CSI report.

Among them, updating the CSI of the measurement hypothesis that requires a large number of CPUs can fully utilize the computing resources of the UE.

Alternatively, the UE updates the CSI of the single TRP measurement assumption in the nth CSI report, and this solution has better backward compatibility.

The above describes that when the UE performs a CSI report (for example, the nth CSI report above), if the number of available CPUs Q is less than the number of CPUs P corresponding to the CSI report, the UE can choose to update the CSI. Partial CSI in the report instead of reporting an unupdated CSI report. In other words, when the number of available CPUs is insufficient to report a CSI report that includes both a single TRP measurement hypothesis and an NCJT measurement hypothesis, the UE only calculates and updates the CSI of a certain measurement hypothesis in the CSI report. Through such a reporting manner, the number of CPUs corresponding to the CSI report can be reduced.

From a time unit, if the calculation of N CSI reports in this time unit needs to start occupying the CPU, the UE sequentially determines whether each CSI report needs to be updated according to the priority of the N CSI reports. After CSI report 0 to CSI report (n-1) with higher priority occupy the idle CPU in sequence, if the remaining available CPU is not enough to calculate the nth CSI report, the UE adopts the method provided in the above embodiment. The nth CSI report is sent in the manner of the UE. Specifically, the UE may send the nth CSI report that only contains the partially updated CSI.

Optionally, the determination of the priority of each CSI report in the N CSI reports may be independent of the type of measurement hypothesis included in the CSI report and/or the number of CPUs corresponding to the CSI report.

In this implementation, when the number of CSI processing units corresponding to the nth CSI report is greater than the number of currently available CSI processing units, the UE indirectly makes the nth CSI report by updating only part of the CSI in the nth CSI report. The number of CSI processing units corresponding to each CSI report is reduced.

Optionally, in another implementation, the priority of each CSI report in the N CSI reports can be determined at least according to the type of measurement hypothesis included in the CSI report and/or corresponding to the CSI report. The number of CPUs is related. In other words, the UE or the network device needs to determine the priority of the CSI report according to the type of measurement hypothesis included in the CSI report and/or the number of CPUs corresponding to the CSI report.

For this implementation, some examples are provided below. The following are examples only, and it is understood that other priority criteria may also be included in the present application.

For example, when a CSI report in the N CSI reports includes an NCJT measurement hypothesis, the CSI report has a higher priority than other CSI reports that do not include an NCJT measurement hypothesis, so that the NCJT measurement hypothesis can be guaranteed to be included. The CSI report of the UE can preferentially occupy the CSI computing resources of the UE.

For another example, the smaller the number of CPUs corresponding to a CSI report, the higher the priority of the CSI report, which can ensure that the CSI report with low complexity can preferentially occupy the CSI computing resources of the UE.

As an example, the UE and the network side can calculate the priority of the CSI report according to the following formula (1):

Pri _iCSI (y,k,c, _s )=3·N _cells ·Ms·y+N _cells ·Ms· _k +Ms·c+ _s (1)

The value of y is determined by the type of CSI report. For aperiodic CSI report, y=0; for semi-persistent CSI report carried by PUSCH, y=1; for semi-persistent CSI report carried by PUCCH, y=2; for periodic CSI reporting, y=3;

The value of k is related to the content of the CSI report, wherein, if the CSI report contains L1-RSRP, that is, when the CSI report is beam-related, k=0; if the CSI report does not contain L1-RSRP, but contains NCJT The reported amount related to the measurement hypothesis, k=1; if the CSI report does not include L1-RSRP and does not include the reported amount related to the NCJT measurement hypothesis, k=2;

c is the index value of the serving cell, N _cells is the high-level parameter, and the maximum number of serving cells is maxNrofservingCells;

s is a configuration identifier of a CSI report, M _s is a high-level parameter, and the maximum number of CSI report configurations is maxNrofCSI-ReportCOnfigurations.

Or, as another example, the UE and the network side can calculate the priority of the CSI report according to the following formula (2):

Pri _iCSI (y,k,c,s)=2·64·N _cells ·M _s ·y+64·N _cells ·M _s ·k+N _cells ·M _s ·O _CPU +M _s ·c·s ( 2)

The value of k is related to the content of the CSI report, wherein, if the CSI report includes L1-RSRP, that is, when the CSI report is beam-related, k=0; if the CSI report does not include L1-RSRP, that is, the CSI report When reporting as non-beam correlation, k=1;

O _CPU is the number of CPUs corresponding to the CSI report;

s is a configuration identifier of the CSI report, M _s is a high-level parameter, and the maximum CSI report configuration number maxNrofCSI-ReportCOnfigurations.

The above embodiments are only examples, and the determination of the priority of the CSI report may also be a combination of the above examples, which is not limited.

By associating the determination of the priority with the NCJT measurement hypothesis included in the CSI report, the network side can have a higher chance to obtain the CSI report including the NCJT measurement hypothesis. When the determination of the priority of the CSI report is related to the number of CPUs corresponding to the CSI report, the utilization rate of the CSI computing resources of the UE can be higher.

The process of sending the CSI report to the network side by the UE has been described in detail above.

As mentioned above, CSI calculation requires a large amount of computation and a very high computational complexity. In order to ensure that the UE has enough time to process the CSI calculation, the UE needs to consider the processing delay of the CSI calculation when reporting the CSI report.

In combination with the technical solutions provided in the present application, the present application defines two time intervals, hereinafter referred to as the first interval (denoted as Z _ref ) and the second interval (denoted as Z' _ref ), wherein the first interval and the second interval is defined as follows.

The first interval: the time interval from the end time of the last symbol of the PDCCH carrying the triggering CSI report to the start time of the first symbol of the PUSCH carrying the corresponding CSI report (including the effect of timing advance).

Second interval: from the end time of the last symbol of the reference signal resource associated with the updated CSI contained in the nth CSI report and the latter resource in the interference measurement resource, to the end time of the uplink resource carrying the nth CSI report The time interval between the start of the first symbol (including the effects of timing advance).

Wherein, the uplink resource carrying the nth CSI report may be PUCCH or PUSCH.

It should be noted that the definition of the second interval takes into account that when the nth CSI report contains multiple types of measurement hypotheses (for example, single TRP measurement hypotheses and NCJT measurement hypotheses), if the number of available CSI processing units is Q is less than the number P of CSI processing units corresponding to the nth CSI report, and the UE chooses to update only the CSI of some measurement hypotheses in the nth CSI report, that is, the nth CSI report will contain the CSI that needs to be updated (denoted as the first CSI) and CSI (denoted as the second CSI) that does not need to be updated. The first CSI that needs to be updated and the second CSI that does not need to be updated are associated with respective reference signal resources and interference measurement resources. When only part of the CSI is updated in the nth CSI report, the CSI calculation delay should not take into account the processing delay of the unupdated CSI. In other words, for the unupdated CSI, the UE does not actually have CSI calculation is performed.

In other words, when a CSI report includes multiple measurement hypotheses, and the CSI report contains only the CSI update of a specific measurement hypothesis (the NCJT measurement hypothesis is taken as an example below, that is, the first CSI is the CSI of the NCJT measurement hypothesis), Then, the determination of the second interval of the CSI report needs to be determined according to the position of the measurement resource associated with the CSI assumed by the NCJT measurement.

For example, when the nth CSI report contains multiple CSIs of different measurement hypotheses, and only the CSI of the NCJT measurement hypotheses needs to be updated, then the second interval _Z'ref is associated with the CSI of the NCJT measurement hypotheses from the nth CSI report Between the end time of the last symbol of the following measurement resource in the CMR and IMR of the 1st CSI report, and the start time of the first symbol of the uplink resource (for example, PUSCH) carrying the nth CSI report (including the effect of timing advance) time interval. In this way, when the measurement resource (including CMR and IMR) associated with the CSI that needs to be updated in the nth CSI report is located behind the measurement resource associated with the CSI that does not need to be updated in time, and the UE is based on the CSI that does not need to be updated The position of the associated measurement resource calculates the second interval, resulting in a mismatch between the calculation result of the second interval and the actual CSI calculation delay by the UE.

An example is given below with reference to FIG. 3 .

Referring to FIG. 3 , FIG. 3 is a schematic diagram of a reference point for processing delay of a CSI report provided by the present application. As shown in FIG. 3 , taking the nth CSI report as an example, assuming that the network device configures the UE to report the CSI report using option 1, and X=1, the nth CSI report includes a single TRP measurement hypothesis and an NCJT measurement hypothesis. The network device pre-configures the UE for the reference signal resource used for channel measurement for the single TRP measurement hypothesis and its associated interference measurement resource for interference measurement, and the reference signal resource group for channel measurement for the NCJT measurement hypothesis and Its associated interference measurement resource for interference measurement. As described in the above embodiment, if the number of CPUs corresponding to the nth CSI report is P and the number of available CPUs Q is less than P, the UE only updates part of the CSI in the nth CSI report, while Not all CSI.

For example, if the UE needs to update the CSI of the single TRP measurement hypothesis in the nth CSI report, the second interval is the last symbol of the reference signal resources associated from the single TRP measurement hypothesis and its associated interference measurement resources after the last symbol The time interval between the end time of , and the start time of the first symbol of the PUSCH carrying the nth CSI report (including the effect of timing advance), as shown in the second interval (1) in FIG. 3 .

For another example, if the UE needs to update the CSI of the NCJT measurement hypothesis in the nth CSI report, the second interval is obtained from multiple reference signal resources corresponding to the reference signal resource group associated with the NCJT measurement hypothesis and their associated interference measurement resources. The time interval between the end time of the last symbol of the latter resource and the start time of the first symbol of the PUSCH carrying the nth CSI report (including the effect of timing advance), as shown in FIG. Two intervals (2).

For another example, if the UE needs to update the CSI of the single TRP measurement hypothesis and the CSI of the NCJT measurement hypothesis in the nth CSI report, since both the CSI of the two measurement hypotheses need to be updated, the second interval is the reference associated with the single TRP measurement hypothesis. The signal resource and its interference measurement resource, the reference signal resource corresponding to the reference signal resource group associated with the NCJT measurement hypothesis, and the end time of the first symbol of the next measurement resource in the reference signal resource group associated with the NCJT measurement hypothesis. The time interval between the start instants of the first symbol of the PUSCH of n CSI reports. Taking FIG. 3 as an example, in terms of time, since the interference measurement resource associated with the single TRP measurement assumption is located at the end, the start moment of the second interval at this time is the last symbol of the interference measurement resource associated with the single TRP measurement assumption. The end time is used as the starting reference point. In this case, the second interval is the second interval ( 1 ) shown in FIG. 3 .

In the actual scheduling process, if the second interval of a CSI report is less than the minimum required value specified by the communication protocol, the UE will not update the CSI report. And when the second interval is greater than or equal to the minimum required value (eg, the second threshold) specified by the communication protocol, and the first interval _Zref is also equal to or greater than the minimum required value specified by the communication protocol (eg, the first threshold) , the UE sends a CSI report containing the updated CSI to the network device.

It should be understood that the definition of the second interval is also applicable in other embodiments herein. The following description will be made with reference to FIG. 4 .
