The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0039] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0040] Existing research results show that AI can achieve corresponding gains in multiple fields such as CSI feedback, beam management, and positioning under the existing 5G design framework, showing considerable application prospects. A typical use case of beam management is time domain beam prediction / tracking under high-speed mobility. Figure 2As shown, for traditional solutions, for example, the beam tracking frequency is set to once every 40ms, and each time the quality of part of the beam is measured and reported according to CSI-ReportConfig. For AI-based time domain beam prediction on the terminal side, for example, the time interval between adjacent sampling points of beam tracking is 40ms, based on the measured quality of the part of the beam at 4 consecutive sampling points, the quality of the best beam in the part of the beam at the next 4 moments is predicted and reported, or the quality of the best beam in all beams at the next 4 moments is predicted and reported, and then the UE sends the beam report according to a specific sending method.

[0041] The AI-based time-domain beam prediction implementation method is to first train based on a larger data set, for example, the data set contains millions of samples, each sample contains the RSRP of all beam pairs at multiple moments, and the RSRP of a small number of beam pairs at several moments is used as the input of the AI ​​model (usually a neural network) during training, and the RSRP of all beam pairs at several moments is used as the label of the AI ​​model output. The parameters in the AI ​​model are continuously updated through the gradient descent algorithm until the error between the AI ​​model output and the label (which can be measured by NMSE) is less than the threshold. At this time, the model converges and has good prediction ability. In actual use, the RSRP results of several moments of configuration measurement are used as the input of the AI ​​model, and the predicted RSRP of all beam pairs at several future moments is output. The base station determines the beam pair used for terminal data transmission based on the predicted RSRP values ​​of the previous K optimal beam pairs at each future moment and the beam pair load, and performs beam indication.

[0042] The existing CSI reporting framework only supports measuring the CSI-RS resource set once / at one time in each CSI resource set period, and does not support configuring CSI resource set measurements with different patterns at different times; it can only report CSI for the measured past time, and cannot indicate reporting of beam quality in the future.

[0043] Table 1 below shows the information content of the existing CSI reporting configuration.

[0044]

[0045] Table 1

[0046] Figure 3 Schematic diagram of the process of configuring the CSI reporting method provided in the embodiment of the present application Figure 1 ,like Figure 3 As shown, the CSI reporting configuration method includes the following steps:

[0047] Step 301: The terminal device receives a CSI reporting configuration sent by a network device, where the CSI reporting configuration is used to configure multiple CSI resource sets, and different CSI resource sets among the multiple CSI resource sets correspond to different measurement times.

[0048] In an optional implementation manner of the present application, the CSI reporting configuration includes first configuration information, where the first configuration information is used to configure multiple patterns of a full set of CSI resources within a CSI resource set period, and the multiple patterns are used to determine the multiple CSI resource sets.

[0049] In an optional implementation manner of the present application, the first configuration information includes at least one of the following information:

[0050] Quantity information, where the quantity information is used to indicate the number of the multiple CSI resource sets or the total number of times the multiple CSI resource sets are sent in the CSI resource set period;

[0051] interval information, where the interval information is used to indicate a time interval between two adjacent CSI resource sets in the CSI resource set period; and

[0052] First information, where the first information is used to indicate each of the patterns in the CSI resource set period.

[0053] Indicatively, the IE shown in Table 2 may be added to CSI-ReportConfig:

[0054]

[0055] Table 2

[0056] Among them, the MeasurementPattern configuration is shown in Table 3:

[0057]

[0058] Table 3

[0059] In this implementation, in one CSI resource set period, a full set of CSI resources of different patterns is repeatedly sent several times, and for each transmission / each moment, the reference signal pattern to be measured is configured to be a subset of the full set.

[0060] In CSI-ReportConfig, CSI-ResourceConfigId indicates the resource location of the first transmission of the full set of CSI resources of different patterns in a cycle. RepeatnrofRSset corresponds to the quantity information, indicating the number of times the base station repeats the transmission of the CSI resource set corresponding to CSI-ResourceConfigId in a cycle. IntervalofRSset corresponds to the interval information, indicating the time interval between two adjacent CSI resource sets in the CSI resource set cycle. MeasurementPattern corresponds to the first information, indicating the CSI resource pattern that needs to be measured at different times in the full set of CSI resources in a bitmap manner.

[0061] In an optional implementation manner of the present application, the CSI reporting configuration includes second configuration information, where the second configuration information is used to configure multiple patterns of the entire CSI resource set, and the multiple patterns are used to determine the multiple CSI resource sets.

[0062] In an optional implementation manner of the present application, the second configuration information includes:

[0063] Second information, where the second information is used to indicate each of the patterns in the plurality of patterns.

[0064] In an optional implementation manner of the present application, the multiple CSI resource sets are measured in different CSI resource set periods or at different times.

[0065] Indicatively, the IE shown in Table 4 may be added to CSI-ReportConfig:

[0066]

[0067] Table 4

[0068] Among them, the MeasurementPattern configuration is as described in Table 5:

[0069]

[0070] Table 5

[0071] In this implementation, each CSI resource set period sends a full set of CSI resources of different patterns, and for each period / each moment, the reference signal pattern that needs to be measured is a subset of the full set. CSI-ResourceConfigId in CSI-ReportConfig configures the full set of CSI resources of different patterns. MeasurementPattern uses a bitmap to indicate the CSI resource pattern that needs to be measured at different periods / moments in the full set of CSI resources. Schematically, CSI resource sets of different patterns are measured in turn at different periods / moments. For example, there are 3 patterns in total. The first resource set period measures measurementpattern1, the second resource set period measures measurementpattern2, the third resource set period measures measurementpattern3, the fourth resource set period measures measurementpattern1, and so on.

[0072] In an optional implementation of the present application, the CSI reporting configuration includes third configuration information, and the third configuration information is used to configure at least one associated CSI reporting configuration associated with the CSI reporting configuration; the CSI reporting configuration is used to configure a first CSI resource set, and each of the associated CSI reporting configurations is used to configure a second CSI resource set, and the first CSI resource set and at least one of the second CSI resource sets form multiple associated CSI resource sets.

[0073] In an optional implementation manner of the present application, the third configuration information includes the following information:

[0074] The associated information is used to indicate a configuration identifier of the at least one associated CSI reporting configuration.

[0075] Indicatively, the IE shown in Table 6 may be added to CSI-ReportConfig:

[0076]

[0077] Table 6

[0078] In this implementation, associated CSI-ReportConfig is configured in CSI-ReportConfig, and CSI resource sets in different CSI-ReportConfig correspond to different measurement patterns respectively. After the terminal completes measurement / prediction within a period of time T according to these associated CSI-ReportConfig, they are reported together. Among them, several assoCSI-ReportConfig are associated with the current CSI-ReportConfig. Starting from a certain moment (for example, the moment corresponding to the CSI resource set configured by the current CSI-ReportConfig), the terminal measures the CSI resource sets of all associated CSI-ReportConfig within a period of time T, and predicts and reports based on these measurement results. T is determined by the terminal. Schematically, T can be a reporting period.

[0079] In an optional implementation of the present application, the CSI reporting configuration includes fourth configuration information, and the fourth configuration information is used to configure multiple associated sub-reporting configurations, each of the sub-reporting configurations is used to configure a CSI resource set, and the multiple CSI resource sets configured by the multiple sub-reporting configurations form multiple associated CSI resource sets.

[0080] Indicatively, the IE shown in Table 7 may be added to CSI-ReportConfig:

[0081]

[0082] Table 7

[0083] In this implementation, several subReportConfigs are configured in CSI-ReportConfig, and the CSI resource sets in different subReportConfigs correspond to different measurement patterns. After the terminal completes measurement / prediction according to these subReportConfigs within a period of time T, they are reported together. Among them, several subReportConfigs are associated, and the terminal starts from a certain moment (for example, the moment corresponding to the CSI resource set configured by the subReportConfig with the smallest ID), measures the CSI resource sets of all associated subReportConfigs within a period of time T, and reports based on these measurement results. T is determined by the terminal, and T can be a reporting period.

[0084] In an optional implementation manner of the present application, the CSI reporting configuration is also used to configure beam prediction information.

[0085] In an optional implementation manner of the present application, the CSI reporting configuration includes fifth configuration information, and the fifth configuration information includes at least one of the following information:

[0086] A predicted quantity, the predicted quantity is used to indicate the quantity at the predicted moment,

[0087] First offset information, wherein the first offset information is used to indicate a time offset of a first predicted moment relative to a reference moment.

[0088] The prediction interval is used to indicate the time interval between two adjacent prediction moments.

[0089] In an optional implementation of the present application, the reference time is the sending time of the first CSI resource set or the sending time or reporting time of the last CSI resource set among the multiple CSI resource sets. The reference time may also be other times, which is not limited in the present application.

[0090] In an optional implementation of the present application, the fifth configuration information also includes first indication information or second indication information, the first indication information is used to instruct the terminal device to report CSI to the network device, and the CSI report includes measurement results of the multiple CSI resource sets; the second indication information is used to instruct the terminal device to report CSI to the network device, and the CSI report includes prediction results corresponding to one or more prediction moments.

[0091] Exemplarily, for the fifth configuration information, an IE as shown in Table 8 may be added to CSI-ReportConfig:

[0092]

[0093] Table 8

[0094] Among them, nwtimeprediction represents the network side reasoning, and the terminal reports the quality of the reference signal measured in the CSI-ReportConfig, which is predicted by the network side. uetimeprediction represents the terminal side reasoning, and the time offset of the first prediction moment relative to the reference moment is slotoffsetofprediction. Starting from the first prediction moment, the beam quality of the next nrofBeamPrediction moments is predicted and reported.

[0095] Exemplarily, for the fifth configuration information, an IE as shown in Table 9 may be added to CSI-ReportConfig:

[0096]

[0097] Table 9

[0098] Among them, nwtimeprediction represents network-side reasoning, and the terminal reports the quality of the reference signal measured in the CSI-ReportConfig. uetimeprediction represents terminal-side reasoning, and the starting time of AI-based prediction is the first transmission time in a cycle of the CSI resource set configured by the current CSI-ReportConfig plus the time offset slotoffset, or the last transmission time in a cycle of the CSI resource set plus the time offset slotoffset, or the reporting time plus the time offset slotoffset. Starting from the predicted starting time, the beam quality of the next nrofBeamPrediction moments is predicted and reported, and the prediction time interval is intervalofPrediction.

[0122] In an optional implementation of the present application, the reporting configuration is carried in radio resource control RRC signaling.

[0123] The technical solution of the embodiment of the present application is illustrated below with reference to specific examples.

[0124] Example 1

[0125] refer to Figure 5 The base station has 8 transmit beams and the terminal has 4 receive beams. The AI-based beam prediction method configures the resource set of CSI-ReportConfig to include 8*4=32 reference signal / beam pairs, and the CSI resource set period is 160ms (1 time slot=1ms).

[0126] Table 10 below gives the pattern-based measurement configuration:

[0127]

[0128]

[0129] Table 10

[0130] The CSI-ResourceConfigId in CSI-ReportConfig indicates the resource location of the first transmission of the entire CSI resource set in a cycle. The base station repeats the CSI resource set corresponding to the CSI-ResourceConfigId for RepeatnrofRSset=4 times in a cycle, and the interval between two adjacent repetitions of the CSI resource set is intervalofRSset=20ms. MeasurementPattern uses a bitmap to indicate that the CSI resource ids that need to be measured at four moments in the entire CSI resource set are 0~7, 8~15, 16~23, and 24~31 respectively.

[0131] When the network side is inferring, the CSI reporting configuration is shown in Table 11:

[0132]

[0133] Table 11

[0134] The terminal reports the RSRP of the CSI reference signal measured at four moments in a cycle. The network side uses the RSRP results at four moments as the AI ​​model input and outputs the RSRP of all beam pairs at the next four moments. For example, if the RSRP of beam pairs 1, 1, 2, 3 is the highest at the 1st, 2nd, 3rd, and 4th moments in the future, and the beam pair load is not overloaded, the base station instructs the terminal to use beam pairs 1, 1, 2, and 3 to transmit data at the 1st, 2nd, 3rd, and 4th moments in the future, respectively.

[0135] When the terminal side is inferring, the CSI reporting configuration is shown in Table 12:

[0136]

[0137] Table 12

[0138] Starting from the moment corresponding to the last resource set in a cycle of the CSI resource set configured by the current CSI-ReportConfig, the time offsets of the four predicted moments relative to the last CSI resource set sending moment in a cycle are 40ms, 80ms, 120ms, and 160ms respectively. The terminal uses the RSRP results of the four configured measured moments as the input of the AI ​​model, outputs the RSRP of all beam pairs in the next four moments, and reports the sequence number and RSRP of the top K optimal beam pairs at each moment in the next four moments to the base station. For example, if the RSRP of beam pairs 1, 1, 2, and 3 is the highest at the 1st, 2nd, 3rd, and 4th moments in the future, and the beam pair load is not overloaded, the base station instructs the terminal to use beam pairs 1, 1, 2, and 3 to transmit data at the 1st, 2nd, 3rd, and 4th moments in the future, respectively.

[0139] Example 2

[0140] refer to Figure 6 , the base station has 32 transmit beams and the terminal has 4 receive beams. The CSI resource set period is 160ms (1 time slot = 1ms).

[0141] Table 13 below gives the pattern-based measurement configuration:

[0142]

[0143]

[0144] Table 13

[0145] Among them, CSI-ReportConfig with id=2, 3, 4 is associated with the current CSI-ReportConfig with id=1, and the resource sets of CSI-ReportConfig with id=1, 2, 3, 4 respectively contain CSI reference signals with id=0~31, 32~63, 64~95, 96~127. Starting from the time corresponding to the CSI resource set in a period of CSI-ReportConfig configuration with id=1, the terminal measures the CSI resource set of CSI-ReportConfig with id=1, 2, 3, 4 in a period, and makes predictions and reports based on these measurement results.

[0146] When the network side is inferring, the CSI reporting configuration is shown in Table 14:

[0147]

[0148] Table 14

[0149] The terminal reports the RSRP of the CSI reference signal of CSI-ReportConfig with id=1 to 4 within a period of CSI-ReportConfig with id=1. The network side uses the RSRP results of 4 moments (4 CSI-ReportConfig) as the input of the AI ​​model, and outputs the RSRP of all beam pairs in the next 4 moments. For example, if the RSRP of beam pairs 1, 1, 2, and 3 is the highest at the 1st, 2nd, 3rd, and 4th moments in the future, and the beam pair load is not overloaded, the base station instructs the terminal to use beam pairs 1, 1, 2, and 3 to transmit data at the 1st, 2nd, 3rd, and 4th moments in the future, respectively.

[0150] When the terminal side is inferring, the CSI reporting configuration is shown in Table 15:

[0151]

[0152] Table 15

[0153] The starting time of AI-based prediction is the transmission time of the CSI resource set configured by the CSI-ReportConfig with the current id = 1 in one cycle plus the time offset slotoffset = 100ms. Starting from the predicted starting time, the beam quality of the next four moments is predicted and reported, and the prediction time interval is 40ms.

[0154] The terminal uses the RSRP results of the four configured measured moments (4 CSI-ReportConfigs) as the input of the AI ​​model, outputs the RSRP of all beam pairs in the next four moments, and reports the sequence number and RSRP of the top K optimal beam pairs at each of the next four moments to the base station. For example, if the RSRP of beam pairs 1, 1, 2, and 3 is the highest at the 1st, 2nd, 3rd, and 4th moments in the future, and the beam pair load is not overloaded, the base station instructs the terminal to use beam pairs 1, 1, 2, and 3 to transmit data at the 1st, 2nd, 3rd, and 4th moments in the future, respectively.

[0155] Example 3

[0156] refer to Figure 7 The base station has 8 transmit beams and the terminal has 4 receive beams. The AI-based beam prediction method configures the resource set of CSI-ReportConfig to include 8*4=32 reference signal / beam pairs, and the CSI resource set period is 20ms (1 time slot=1ms).

[0157] Table 16 below gives the pattern-based measurement configuration:

[0158]

[0159]

[0160] Table 16

[0161] In CSI-ResourceConfig, CSI-ResourceConfigId indicates the resource location of the entire set of CSI resources. MeasurementPattern uses bitmap to indicate the CSI resource IDs of the four patterns in the entire set of CSI resources to be measured, which are 0 to 7, 8 to 15, 16 to 23, and 24 to 31. The terminal measures the four patterns in turn at different periods / times. The reporting period is 160ms.

[0162] When the network side is inferring, the CSI reporting configuration is shown in Table 17:

[0163]

[0164] Table 17

[0165] The terminal reports the RSRP of the CSI reference signal measured at multiple times within a reporting period. The network side uses the RSRP results of some of these times as the AI ​​model input and outputs the RSRP of all beam pairs at the next four times. For example, if the RSRP of beam pairs 1, 1, 2, 3 is the highest at the 1st, 2nd, 3rd, and 4th times in the future, and the beam pair load is not overloaded, the base station instructs the terminal to use beam pairs 1, 1, 2, and 3 to transmit data at the 1st, 2nd, 3rd, and 4th times in the future, respectively.

[0166] When the terminal side is inferring, the CSI reporting configuration is shown in Table 18:

[0167]

[0168] Table 18

[0169] The starting time of AI-based prediction is the reporting time plus the time offset slotoffset = 20ms. Starting from the predicted starting time, the beam quality of the next four moments is predicted and reported, with a prediction time interval of 40ms.

[0170] The terminal uses the RSRP results of the configured measurements at the four moments as the input of the AI ​​model, outputs the RSRP of all beam pairs at the next four moments, and reports the sequence number and RSRP of the top K optimal beam pairs at each of the next four moments to the base station. For example, if the RSRP of beam pairs 1, 1, 2, and 3 is the highest at the 1st, 2nd, 3rd, and 4th moments in the future, and the beam pair load is not overloaded, the base station instructs the terminal to use beam pairs 1, 1, 2, and 3 to transmit data at the 1st, 2nd, 3rd, and 4th moments in the future, respectively.

[0171] It should be noted that the above scheme is illustrated by taking AI-based beam prediction as an example, and the present application is not limited to this. The above scheme can also be used for time series analysis and regression analysis.

[0172] It should be noted that the above scheme is described using time domain beam prediction as an example, and the present application is not limited to this. The above scheme can also be used for CSI prediction and network energy saving.

[0173] The CSI reporting configuration method provided in the embodiment of the present application enhances the CSI reporting framework, enabling the base station to indicate pattern-based CSI resource set measurements and CSI reporting for a period of time in the future to support future AI-based beam prediction.
