In addition, the character " / " in this paper generally represents an "or" relationship between the associated objects.

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

[0040] The existing research results show that AI can obtain corresponding gain in CSI feedback, beam management, positioning and other fields under the existing 5G design framework, and shows considerable application prospect. The typical use case of beam management is time domain beam prediction / tracking under high speed movement. For example, Figure 2As shown, for the conventional scheme, the beam tracking frequency is set to once every 40 ms, and the partial beam quality is reported according to the CSI-ReportConfig measurement each time. For the AI-based time-domain beam prediction on the terminal side, the time interval between adjacent sampling points of beam tracking is 40 ms, and according to the partial beam quality of the measured 4 consecutive sampling points, the quality of the best beam in the partial beam at the next 4 time points is predicted and reported, or the quality of the best beam in all beams at the next 4 time points is predicted and reported, and then the UE sends the beam report according to a specific sending mode.

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

[0042] The existing CSI reporting framework only supports measuring the CSI-RS resource set at one time point once per CSI resource set period, and does not support configuring different patterns of CSI resource set measurement at different time points; only the past time CSI can be reported, and the beam quality in the future period of time cannot be indicated for reporting.

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

[0044]

[0045] Table 1

[0046] Figure 3 The flowchart of the configuration method of the CSI reporting provided by the embodiments of the present application is shown in Figure 1 As shown in Figure 3 The configuration method of the CSI reporting includes the following steps:

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

[0048] In one optional embodiment of this application, the CSI reporting configuration includes first configuration information, which is used to configure multiple patterns of the complete 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 one optional embodiment of this application, the first configuration information includes at least one of the following:

[0050] Quantity information, which indicates the number of the plurality of CSI resource sets or the total number of transmissions of the plurality of CSI resource sets during the CSI resource set period;

[0053] As an example, you can add IEs as shown in Table 2 to CSI-ReportConfig:

[0054]

[0055] Table 2

[0056] The MeasurementPattern configuration is shown in Table 3:

[0057]

[0058] Table 3

[0059] In this implementation, within a CSI resource set cycle, the entire set of CSI resources with different patterns is repeatedly sent several times. For each transmission / each moment, the reference signal pattern to be measured is configured to be a subset of the entire set.

[0060] CSI-ResourceConfigId in CSI-ReportConfig indicates the resource position of the first transmission of the full set of CSI resource patterns in a period, RepeatnrofRSset corresponds to the number information, indicating the number of times the base station repeats the transmission of the CSI resource set corresponding to CSI-ResourceConfigId in a period, intervalofRSset corresponds to the interval information, indicating the time interval of the adjacent two times of the CSI resource set in the period of the CSI resource set. The first information corresponding to MeasurementPattern is indicated by bitmap, indicating the CSI resource pattern to be measured at different times in the full set of CSI resources.

[0066]

[0067] Table 4

[0068] In the table, MeasurementPattern is configured as shown in Table 5:

[0069]

[0070] Table 5

[0071] In this embodiment, the full set of CSI resource sets with different patterns are sent periodically, and for each period / each time instance, the configured reference signal pattern to be measured is a subset of the full set. The full set of CSI resource sets with different patterns is configured in CSI-ReportConfig with CSI-ResourceConfigId. MeasurementPattern indicates the CSI resource pattern to be measured in the full set of CSI resource sets in different periods / time instances with bitmap. Illustratively, different patterns of CSI resource sets are measured in different periods / time instances, for example, there are three patterns, measurementpattern1 is measured in the first resource set period, measurementpattern2 is measured in the second resource set period, measurementpattern3 is measured in the third resource set period, measurementpattern1 is measured in the fourth resource set period, and so on.

[0072] In an optional embodiment of the present application, the CSI reporting configuration includes third configuration information, 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, 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 a plurality of associated CSI resource sets.

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

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

[0075] Illustratively, the IE in Table 6 can be added in CSI-ReportConfig:

[0076]

[0077] Table 6

[0078] In this embodiment, the associated CSI-ReportConfig is configured in the CSI-ReportConfig, and the CSI resource set in different CSI-ReportConfig corresponds to different measurement patterns, respectively. After the terminal completes the measurement / prediction within a period T according to the associated CSI-ReportConfig, the terminal reports together. If a plurality of assoCSI-ReportConfig are associated with the current CSI-ReportConfig, the terminal starts to measure the CSI resource set of all associated CSI-ReportConfig within a period T from a certain time (for example, the time corresponding to the CSI resource set configured by the CSI-ReportConfig with the smallest ID). Based on the measurement results, the terminal performs prediction and reporting. T is determined by the terminal, and T can be the reporting period.

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

[0081]

[0082] Table 7

[0083] In this embodiment, a plurality of subReportConfig are configured in the CSI-ReportConfig, and the CSI resource set in different subReportConfig corresponds to different measurement patterns, respectively. After the terminal completes the measurement / prediction within a period T according to the subReportConfig, the terminal reports together. If a plurality of subReportConfig are associated, the terminal starts to measure the CSI resource set of all associated subReportConfig within a period T from a certain time (for example, the time corresponding to the CSI resource set configured by the subReportConfig with the smallest ID). Based on the measurement results, the terminal performs prediction and reporting. T is determined by the terminal, and T can be the reporting period.

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

[0123] The technical solutions of the embodiments of the present application are exemplified below in combination with specific examples.

[0124] Example One

[0125] Reference Figure 5 There are 8 transmission beams of the base station and 4 reception beams of the terminal. The AI-based beam prediction method configures 8*4=32 reference signal / beam pairs in the resource set of CSI-ReportConfig, and the CSI resource set period is 160ms (1 time slot=1ms).

[0126] The following Table 10 gives the measurement configuration based on the pattern:

[0127]

[0128]

[0129] Table 10

[0130] CSI-ResourceConfigId in CSI-ReportConfig indicates the resource position of the first transmission of the full set of CSI resources in a period. The base station repeatedly transmits the CSI resource set corresponding to CSI-ResourceConfigId RepeatnrofRSset=4 times in a period, and the time interval between the adjacent two times of CSI resource set is intervalofRSset=20ms. MeasurementPattern uses bitmap to indicate that the CSI resource ids of the CSI resources to be measured at 4 moments in the full set of CSI resources are 0-7, 8-15, 16-23, and 24-31 respectively.

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

[0132]

[0133] Table 11

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

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

[0136]

[0137] Table 12

[0138] From the time point corresponding to the last resource set in a period of the CSI resource set configured by the current CSI-ReportConfig, the time offsets of the 4 predicted time points relative to the time point of the last CSI resource set in a period are 40ms, 80ms, 120ms, and 160ms respectively. The terminal takes the RSRP results of the 4 time points measured by the configuration as AI model input, and outputs the RSRP of all beam pairs at the future 4 time points. The terminal reports the serial number and RSRP of the top K optimal beam pairs at each of the future 4 time points to the base station. For example, the RSRP of beam pair 1, 1, 2, 3 at the future 1st, 2nd, 3rd, 4th time points is the highest, and the beam pair load is not overloaded, then the base station instructs the terminal to use beam pair 1, 1, 2, 3 to transmit data at the future 1st, 2nd, 3rd, 4th time points respectively.

[0139] Example Two

[0140] Reference Figure 6 There are 32 transmission beams in the base station and 4 reception beams in the terminal. The CSI resource set period is 160ms (1 time slot = 1ms).

[0141] The following Table 13 gives the measurement configuration based on the pattern:

[0142]

[0143]

[0144] Table 13

[0145] CSI-ReportConfig with id=1, 2, 3, 4 are associated with the current CSI-ReportConfig with id=1, and the CSI reference signals in the resource sets of CSI-ReportConfig with id=1, 2, 3, 4 are respectively id=0~31, 32~63, 64~95, 96~127. The terminal measures the CSI reference signals in the resource sets of CSI-ReportConfig with id=1, 2, 3, 4 in one period of the CSI resource set of CSI-ReportConfig with id=1, and performs prediction and reporting based on the measurement results.

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

[0147]

[0148] Table 14

[0149] The terminal reports the RSRP of the CSI reference signals of CSI-ReportConfig with id=1~4 in one period of the CSI resource set of CSI-ReportConfig with id=1. The network side takes the RSRP results of 4 time points (4 CSI-ReportConfig) as the AI model input, and outputs the RSRP of all beam pairs at the future 4 time points. For example, the RSRP of beam pair 1, 1, 2, 3 at the future 1st, 2nd, 3rd, 4th time points is the highest, and the beam pair load is not overloaded, then the base station instructs the terminal to use beam pair 1, 1, 2, 3 to transmit data at the future 1st, 2nd, 3rd, 4th time points respectively.

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

[0151]

[0152] Table 15

[0153] The starting time of the AI-based prediction is the transmission time in one period of the CSI resource set of the current CSI-ReportConfig with id=1 plus the time offset slotoffset=100ms. From the starting time of the prediction, the beam quality at the future 4 time points is predicted and reported, and the prediction time interval is 40ms.

[0154] The terminal inputs the RSRP results of 4 time instants (4 CSI-ReportConfig) of the configured measurement to the AI model, outputs the RSRP of all beam pairs in the future 4 time instants, and reports the serial number and RSRP of the top K optimal beam pairs in each time instant in the future 4 time instants to the base station. For example, the RSRP of beam pair 1, 1, 2, and 3 in the future 1st, 2nd, 3rd, and 4th time instants is the highest, and the beam pair load is not overloaded, then the base station instructs the terminal to use beam pair 1, 1, 2, and 3 to transmit data in the future 1st, 2nd, 3rd, and 4th time instants respectively.

[0155] Example Three

[0156] Reference Figure 7 There are 8 transmitting beams and 4 receiving beams in the base station. The AI-based beam prediction method configures 8*4=32 reference signals / beam pairs in the resource set of CSI-ReportConfig, and the CSI resource set period is 20ms (1 time slot=1ms).

[0157] The following Table 16 shows the measurement configuration based on the pattern:

[0158]

[0159]

[0160] Table 16

[0161] The CSI-ResourceConfigId in CSI-ReportConfig indicates the resource location of the CSI resource set, and the MeasurementPattern uses bitmap to indicate the CSI resource id of the 4 patterns to be measured in the CSI resource set, which are 0-7, 8-15, 16-23, and 24-31 respectively. The terminal measures the 4 patterns in turn at different periods / time instants. The reporting period is 160ms.

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

[0163]

[0164] Table 17

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

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

[0167]

[0168] Table 18

[0169] The starting time of the AI-based prediction is the reporting time plus a time offset slotoffset = 20 ms. From the starting time of the prediction, the beam quality at the next 4 times is predicted and reported, and the prediction time interval is 40 ms.

[0170] The terminal takes the RSRP results of the 4 times of the configured measurement as the AI model input, outputs the RSRP of all beam pairs at the next 4 times, and reports the serial number and RSRP of the top K optimal beam pairs at each of the next 4 times to the base station, for example, the RSRP of beam pair 1, 1, 2, and 3 at the next 1st, 2nd, 3rd, and 4th times is the highest, and the beam pair load is not overloaded, then the base station instructs the terminal to use beam pair 1, 1, 2, and 3 to transmit data at the next 1st, 2nd, 3rd, and 4th times respectively.

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

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

[0173] The CSI reporting configuration method provided by the embodiment of the present application enhances the CSI reporting framework, and can enable the base station to instruct the measurement of the CSI resource set based on the pattern and the CSI reporting in the future, to support the AI-based beam prediction in the future.

[0174] In the existing scheme, the CSI resource set of one CSI-ReportConfig can be configured with up to 64 reference signals, and the CSI reporting configuration method provided by the embodiment of the present application can be applied to the case where the total set of reference signals to be measured is greater than 64.
