The NR Rel-16 supports multi-TRP based transmission, i.e. communication between the ue and one or more transmitting/receiving points TRP, and therefore, for CSI calculation of the multi-TRP, interference of each transmitting/receiving point needs to be considered when calculating CSI associated with each transmitting/receiving point. At present, NR Rel-16 does not carry out relevant standardization work on CSI under multi-TRP, namely, a specific CSI scheme of the multi-TRP is not available at present.

Referring to fig. 2, fig. 2 is a flowchart illustrating a CSI processing method according to an embodiment of the disclosure.

The method may be implemented by a user equipment, as shown in fig. 2, and includes:

step S11, receiving configuration information, wherein the configuration information comprises CSI configuration information of multiple transmitting and receiving points;

step S12, if the total number of channel state information processing units that are started to be occupied by CSI reports in the CSI configuration information is greater than the number of channel state information processing units (CPUs) that are not occupied in the same symbol, processing one or more CSI reports corresponding to the CSI configuration information according to the CSI configuration information.

Through the above method, the embodiment of the disclosure can process one or more CSI reports corresponding to CSI configuration information according to the CSI configuration information under the condition that the total number of channel state information processing units that are initially occupied by CSI reports in the received CSI configuration information is greater than the number of channel state information processing units that are not occupied in the same symbol, so as to adapt to multiple TRP scenarios, and process CSI in the multiple TRP scenarios, so that each TRP can adapt to channel conditions, and reliability of communication is ensured.

It should be noted that the embodiments of the present disclosure can be applied to a single TRP scenario in addition to a multi-TRP scenario (including more than 2 TRPs).

The "CSI report in CSI configuration information" may represent a CSI report that needs to be calculated and generated by the user equipment.

In a possible implementation manner, the CSI configuration information of the multiple transmission and reception points included in the CSI configuration information may be CSI configuration information under the assumption of multiple transmission and reception points TRP transmission.

In a possible implementation manner, each TRP may send CSI configuration information through higher layer information (e.g., RRC information, etc.), and/or downlink control information DCI triggers CSI computation feedback, and the embodiment of the present disclosure is not limited to the manner in which the TRP sends CSI configuration information.

In one example, when the user equipment receives the CSI configuration information, information related to a CSI report configured by the network may be determined according to the CSI configuration information, and a CSI processing unit that needs to be occupied by the CSI report (i.e., a CSI processing unit that starts to be occupied) may be calculated according to a related communication protocol and configuration. Of course, the embodiment of the present disclosure does not limit the specific implementation of how to calculate the number of CSI processing units that are occupied by the CSI report.

In a possible implementation, the CSI processing unit may be configured to calculate parameters such as channel quality according to the CSI configuration information, so as to obtain the CSI report.

In one possible implementation, the user equipment may send the number of CSI processing elements that can support the maximum parallel computation to the TRP in advance, so that the TRP may know the number of CSI processing elements of the user equipment.

In one possible implementation, the "same symbol" in step S12 may be the same orthogonal frequency division multiplexing OFDM symbol, and the "same symbol" may represent one network transmission.

Of course, in other embodiments, different symbols are possible.

In this embodiment of the present disclosure, the processing, in step S12, one or more CSI reports corresponding to the CSI configuration information according to the CSI configuration information may include various embodiments, which are described below as an example.

Referring to fig. 3, fig. 3 is a flowchart illustrating a CSI processing method according to an embodiment of the disclosure.

In a possible implementation manner, as shown in fig. 3, the processing, by step S12, one or more CSI reports corresponding to the CSI configuration information according to the CSI configuration information may include:

step S121, processing one or more CSI reports corresponding to the CSI configuration information in a first mode, wherein in the first mode, 1 CSI report carries CSI information of one or more sending and receiving points; or

Step S122, processing one or more CSI reports corresponding to the CSI configuration information in a second manner, where in the second manner, 1 CSI report only carries CSI information of 1 sending and receiving point.

Through the above method, the present disclosure may process one or more CSI reports according to different processing manners, thereby increasing flexibility and environmental adaptability.

In one example, the first mode and the second mode may be configured in advance, and those skilled in the art may configure the first mode or the second mode according to needs and actual situations.

In one example, the network may configure the user equipment to process one or more CSI reports corresponding to the CSI configuration information in a first manner, and assuming that the communication system includes 3 TRPs, the network may configure the terminal to transmit CSI information of 1, or 2, or 3 TRPs using 1 CSI report.

In an example, processing one or more CSI reports corresponding to the CSI configuration information in a first manner may include the user equipment obtaining a plurality of CSI information according to the CSI configuration information, generating one CSI report from the plurality of CSI information, and sending the one CSI report.

In one example, the network may configure the user equipment to process one or more CSI reports corresponding to the CSI configuration information in a second manner, and assuming that the communication system includes 3 TRPs, the network may configure the terminal to report the CSI information of the 3 TRPs respectively using the 3 CSI reports.

In an example, processing one or more CSI reports corresponding to the CSI configuration information in a second manner may include the user equipment obtaining a plurality of CSI information according to the CSI configuration information, and sending the CSI information as independent CSI reports.

In an example, whether one or more CSI reports corresponding to the CSI configuration information are processed in the first manner or the second manner, after obtaining the one or more CSI reports, the user equipment may select to send the one or more CSI reports to a certain TRP, or send the one or more CSI reports to a plurality of TRPs, which is not limited in the embodiment of the present disclosure.

When the ue is configured to process the one or more CSI reports corresponding to the CSI configuration information in the first manner, the step S12 may include processing the one or more CSI reports corresponding to the CSI configuration information according to the CSI configuration information, and includes:

In one example, if the channel state information processing unit that is initially occupied by the CSI report of any one of the plurality of TRPs is larger than the unoccupied CSI processing unit, the number of the unoccupied CSI processing units of the user equipment cannot complete calculation and generation of the CSI report of any one of the TRPs, and therefore the user equipment may not update the CSI report, thereby adapting to the current computing environment to improve flexibility and environmental adaptability.

In a possible implementation manner, in the case that the step S121 processes one or more CSI reports corresponding to the CSI configuration information in a first manner, the processing one or more CSI reports corresponding to the CSI configuration information according to the CSI configuration information may include:

In one example, it may be determined whether there are N TRPs having CSI reporting start occupying CSI processing units whose total number is less than or equal to the number of unoccupied CSI processing units in case that it is determined that the number of M TRPs having CSI reporting start occupying CSI processing units is greater than the number of unoccupied CSI processing units in the same symbol, where M represents the total number of configured transmission reception points.

When the total number of the CSI processing units that are initially occupied by the CSI reports of N TRPs in the M TRPs is less than or equal to the number of the unoccupied CSI processing units in the user equipment, the user equipment may determine that the current unoccupied CSI processing unit has the ability to calculate and generate the CSI reports of N TRPs (first CSI reports), and therefore, the user equipment starts an update procedure to update the first CSI report.

In one example, updating the first CSI report may include calculating CSI information of N TRPs according to CSI configuration information by using an unoccupied CSI processing unit, generating the first CSI report in case of obtaining the CSI information of the N TRPs, and transmitting the first CSI report.

The disclosed embodiments may be implemented in various ways to determine the N TRPs associated with the first CSI report, that is, the related N TRPs transmitted in the first CSI report may be determined in various ways, which is described as an example below.

In one possible embodiment, the CSI configuration information may include a reference signal resource CSI-RS for channel measurement and/or an interference measurement resource for interference measurement.

In an example, the user equipment may calculate and generate a CSI report according to the CSI-RS, so as to determine parameters such as channel quality of a current channel, may also calculate and generate a CSI report according to the interference measurement resource, so as to determine information such as an interference degree of other TRPs on the current TRP, or calculate and generate a CSI report according to the CSI-RS and the interference measurement resource, which is not limited in this disclosure.

Of course, the above description is exemplary, and in other embodiments, the CSI configuration information may further include other measurement resources to complete other measurement items, which is not limited in this disclosure.

In one possible implementation, the CSI information of the N transmission and reception points in the first CSI report may correspond to CSI information of N transmission and reception points with the earliest occurrence of reference signal resources and/or interference measurement resources among CSI configuration information of the M transmission and reception points.

In an example, the ue may determine, according to an occurrence time of a reference signal resource or an interference measurement resource, N TRPs related to CSI information reported in a first CSI report, and when an occurrence time of CSI-RS or an interference measurement resource corresponding to first N sending and receiving points of M sending and receiving points is the earliest and a total number of CSI processing units that are initially occupied by CSI reports of the first N sending and receiving points is less than or equal to a number of unoccupied CSI processing units, may process the CSI reports of the first N sending and receiving points, so as to obtain the first CSI report.

In one possible implementation, the CSI information of the N transmission and reception points in the first CSI report may correspond to CSI information of N transmission and reception points with the smallest reference signal resource identifier and/or interference measurement resource identifier in the CSI configuration information of the M transmission and reception points.

In one example, the identification of the reference signal resource may include a number of the reference signal resource, the identification of the interference measurement resource may include a number of the interference measurement resource, and a size of the number may be used to indicate a priority level at which the corresponding CSI information is processed, for example, a smaller number may be regarded as a higher priority level, that is, the CSI information corresponding to the measurement resource with a smaller number may be processed preferentially.

In one example, the user equipment may determine, according to the CSI configuration information, an identifier of a CSI-RS and/or an identifier of an interference measurement resource associated with a CSI report of each TRP, and determine first N identified (smallest numbered) TRPs, and may process, in a case that a total number of CSI information processing units occupied by the CSI reports of the N TRPs at the beginning is less than or equal to the number of unoccupied CSI processing units, the CSI reports of the TRPs identified as the first N to obtain the first CSI report.

The above describes a case where one or more CSI reports corresponding to the CSI configuration information are processed in a first manner, and the following describes an exemplary case where one or more CSI reports corresponding to the CSI configuration information are processed in a second manner.

In a possible implementation manner, in the case that the step S122 processes one or more CSI reports corresponding to the CSI configuration information in the second manner, the processing one or more CSI reports corresponding to the CSI configuration information according to the CSI configuration information may include:

In one example, when the total number of the channel state information processing units occupied by the CSI reports of the P TRPs is greater than the number of the unoccupied CSI processing units, it indicates that the calculation and generation of the CSI reports of the P TRPs cannot be realized by the remaining available CSI processing units of the user equipment, and therefore, the user equipment may choose not to update the P CSI reports of the P TRPs to adapt to the application environment of the current user equipment, thereby providing flexibility and environmental adaptability.

In a possible implementation, the not updating the P CSI reports may include:

In one example, P may be 1, that is, when the number of CSI processing elements occupied by a CSI report of any one of the plurality of TRPs is greater than the number of unoccupied CSI processing elements, it indicates that the ue cannot complete the calculation and generation of the CSI report of any one of the plurality of TRPs, and therefore, the ue may choose not to update the P CSI reports.

In a possible implementation manner, in the case that the step S122 processes one or more CSI reports corresponding to the CSI configuration information in the second manner, the processing one or more CSI reports corresponding to the CSI configuration information according to the CSI configuration information may further include:

and if the total number of the channel state information processing units which are started to be occupied by the T CSI reports is less than or equal to the number of the unoccupied channel state information processing units, updating the T second CSI reports, wherein the second CSI reports comprise CSI information of a corresponding sending and receiving point, T is less than Q, Q is more than or equal to 1 and less than or equal to the total number of the sending and receiving points, and Q is an integer.

In one example, when the total number of CSI processing elements that are initially occupied by CSI reports of Q TRPs in the multiple TRPs is greater than the number of CSI processing elements that are not occupied by the user equipment, the user equipment may update the CSI reports when a certain condition is satisfied, thereby implementing measurement of channel conditions.

In one example, the user equipment may continue to determine whether the total number of CSI process elements that are occupied by the T CSI reports is less than or equal to the number of unoccupied CSI process elements, and in a case that the total number of CSI process elements that are occupied by the T CSI reports is less than or equal to the number of unoccupied CSI process elements, the user equipment may determine that the processing capability of the current CSI process element is sufficient to complete the calculation and generation of the T CSI reports, and thus, the user equipment may start the calculation and generation of the CSI reports of the T TRPs to obtain the plurality of second CSI reports.

In a possible implementation manner, the processing one or more CSI reports corresponding to the CSI configuration information according to the CSI configuration information may further include:

determining T CSI reports from O CSI reports, wherein the number of channel state information processing units occupied by each CSI report in the O CSI reports is less than or equal to the number of unoccupied channel state information processing units, T is less than or equal to O, and O is less than Q.

In one example, in a case that the total number of the channel state information processing units occupied by the Q CSI reports of the multiple transmission and reception points is greater than the number of the unoccupied channel state information processing units, the user equipment may continuously determine whether the total number of the CSI processing units occupied by the O CSI reports is greater than the number of the unoccupied CSI processing units, and in a case that the CSI processing units occupied by each of the O CSI reports is less than or equal to the number of the unoccupied CSI processing units, the user equipment may determine T CSI reports from the O CSI reports.

In one possible embodiment, the CSI configuration information may include a number of CSI reports, reference signal resources for channel measurement, and/or interference measurement resources for interference measurement, or other information.

In one possible implementation, the embodiments of the present disclosure may determine which TRPs (or O CSI reports) the T CSI reports correspond to based on the number of CSI reports, reference signal resources used for channel measurement, and/or interference measurement resources used for interference measurement.

In one example, the T second CSI reports may correspond to T CSI reports of the smallest number of CSI reports among the O CSI reports.

In one example, the T second CSI reports may correspond to the T CSI reports for which the earliest occurrence of the associated reference signal resource and/or interference measurement resource among the O CSI reports.

Of course, the above description is exemplary, and the user equipment may also determine T CSI reports directly from Q CSI reports, for example, sequentially accumulate the numbers of CSI processing units that the T CSI reports start to occupy, according to the numbers of the Q CSI reports and the occurrence time of the associated measurement resources, starting from a CSI report that the number of the Q CSI reports is earlier or starting from a CSI report that the occurrence time of the measurement resources of the Q CSI reports is earlier, if the total number of CSI processing units that the T CSI reports start to occupy is less than or equal to the number of unoccupied CSI processing units, determine the T CSI reports, and process the T CSI reports according to the CSI configuration information to obtain a plurality of second CSI reports.

In a possible implementation manner, the ue may determine the number of CSI reports and the occurrence time of measurement resources (CSI-RS, interference measurement resources, etc.) according to the CSI configuration information, so as to determine T CSI reports to be processed according to the number of CSI reports or the occurrence time of measurement resources.

In one example, when determining the occurrence time of the measurement resource, the embodiments of the present disclosure may determine by using a first OFDM symbol of the multiple measurement resources, and may determine the earliest occurrence time of the measurement resource according to the first OFDM symbol, thereby determining the occurrence order of the measurement resources.

Of course, the disclosed embodiments are not limited thereto, and in other embodiments, a person skilled in the art may determine the occurrence time of the measurement resource in other manners.

In the above manner, the embodiments of the present disclosure may quickly determine T CSI reports.

By the method, the CSI reports under a multi-TRP scene can be processed, and when the total number of CSI processing units which are occupied by the CSI reports of the CSI configuration information sent by the TRP is larger than the number of the unoccupied CSI processing units, one or more CSI reports can be processed according to the CSI configuration information, so that channel measurement is realized by using the available CSI processing units of the user equipment, and the CSI reports are obtained.

Referring to fig. 4 clearly, fig. 4 shows a block diagram of a CSI processing apparatus according to an embodiment of the present disclosure.

The transposing may be applied to a user equipment, as shown in fig. 4, the apparatus comprising:

Through the above apparatus, in the embodiment of the present disclosure, when the total number of channel state information processing units that are initially occupied by CSI reports in received CSI configuration information is greater than the number of channel state information processing units that are not occupied in the same symbol, one or more CSI reports corresponding to the CSI configuration information are processed according to the CSI configuration information, so as to adapt to multiple TRP scenarios, and process CSI in multiple TRP scenarios, so that each TRP can adapt to channel conditions, and reliability of communication is ensured.
