As used herein, "terminal" includes, but is not limited to, a connection via a wired line, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection; and / or another data connection / network; and / or via a wireless interface, such as for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a Digital Video Broadcasting-Handheld (DVB-H) network, a satellite network, an Amplitude Modulation (AM)-Frequency Modulation (FM) broadcast transmitter; and / or another terminal configured to receive / send communication signals; and / or an Internet of Things (IoT) device.

[0039] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0040] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1 as an example, the communication device may include a network device 110 and a terminal 120 having a communication function.

[0041] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0042] 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.

[0043] Existing research results show that artificial intelligence (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 for beam management is time-domain beam prediction / tracking under high-speed mobility. As shown in Figure 2, 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 the Channel State Information-Report Configuration (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.

[0044] The AI-based time-domain beam prediction method first trains on a large dataset, such as one containing millions of samples, each containing the Reference Signal Received Power (RSRP) of all beam pairs at multiple time instants. During training, the RSRP values ​​of a small number of beam pairs at several time instants are used as input to an AI model (typically a neural network), and the RSRP values ​​of all beam pairs at several time instants are used as labels for the AI ​​model's output. The AI ​​model's parameters are continuously updated using a gradient descent algorithm until the error between the AI ​​model output and the label (measured by the Normalized Mean Square Error (NMSE)) is less than a threshold. This indicates that the model has converged and has good prediction capabilities. In actual use, RSRP values ​​measured at several time instants are used as input to the AI ​​model, which then outputs predicted RSRP values ​​for all beam pairs at several future time instants. Based on the predicted RSRP values ​​of the K optimal beam pairs at each future time instant and the beam pair load, the base station determines the beam pair to use for terminal data transmission and issues beam instructions.

[0045] 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 measuring CSI resource sets 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.

[0046] Table 1 below shows the information content of the existing CSI reporting configuration.

[0047] Table 1

[0048] FIG3 is a flowchart of a method for configuring CSI reporting according to an embodiment of the present application. As shown in FIG3 , the method for configuring CSI reporting includes the following steps:

[0049] 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, where different CSI resource sets in the multiple CSI resource sets correspond to different measurement times.

[0050] 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.

[0051] In an optional implementation manner of the present application, the first configuration information includes at least one of the following information:

[0052] 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;

[0053] 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

[0054] First information, where the first information is used to indicate each of the patterns in the CSI resource set period.

[0055] Illustratively, the information element (IE) shown in Table 2 may be added to the CSI-ReportConfig:

[0056] Table 2

[0057] Among them, the MeasurementPattern configuration is shown in Table 3:

[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. For each transmission / each moment, the reference signal pattern configured to be measured is a subset of the full set.

[0060] In CSI-ResourceConfig, CSI-ResourceConfigId indicates the resource location of the first transmission of the full set of CSI resources with different patterns within a period. RepeatnrofRSset corresponds to the quantity information, indicating the number of times the base station repeats the CSI resource set corresponding to CSI-ResourceConfigId within a period. IntervalofRSset corresponds to the interval information, indicating the time interval between two adjacent CSI resource sets within the CSI resource set period. MeasurementPatern corresponds to the first information, indicating the CSI resource pattern to be measured at different times within the full set of CSI resources in a bitmap format.

[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 full set of CSI resources, 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] For example, the IE shown in Table 4 can be added to CSI-ReportConfig:

[0066] Table 4

[0067] The MeasurementPattern configuration is as described in Table 5:

[0068] Table 5

[0069] In this implementation, each CSI resource set periodically sends a full set of CSI resources of different patterns. For each period / time, the reference signal pattern configured 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 patterns that need to be measured at different periods / times in the full set of CSI resources. Schematically, CSI resource sets of different patterns are measured in turn at different periods / times. For example, there are three patterns in total: 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.

[0070] In an optional embodiment of the present application, the CSI reporting configuration includes third configuration information, where 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 associated CSI reporting configuration 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.

[0071] In an optional implementation manner of the present application, the third configuration information includes the following information:

[0072] Association information, where the association information is used to indicate a configuration identifier of the at least one associated CSI reporting configuration.

[0073] For example, the IE shown in Table 6 can be added to CSI-ReportConfig:

[0074] Table 6

[0075] In this implementation, associated CSI-ReportConfigs are configured in the CSI-ReportConfig, and the CSI resource sets in different CSI-ReportConfigs correspond to different measurement patterns. The terminal completes measurement / prediction according to these associated CSI-ReportConfigs within a period of time T and reports them together. Among them, several assoCSI-ReportConfigs 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-ReportConfigs within a period of time T, and makes predictions and reports based on these measurement results. T is determined by the terminal. Schematically, T can be a reporting period.

[0076] In an optional embodiment 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.

[0077] For example, the IE shown in Table 7 may be added to the CSI-ReportConfig:

[0078] Table 7

[0079] In this implementation, several subReportConfigs are configured in the CSI-ReportConfig. The CSI resource sets in different subReportConfigs correspond to different measurement patterns. The terminal completes measurement / prediction based on these subReportConfigs within a period of time T and reports them together. Several subReportConfigs are associated. Starting from a certain moment (for example, the moment corresponding to the CSI resource set configured by the subReportConfig with the smallest ID), the terminal 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 can be a reporting period.

[0080] In an optional implementation manner of the present application, the CSI reporting configuration is also used to configure beam prediction information.

[0081] 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:

[0082] Prediction quantity, the prediction quantity is used to indicate the quantity at the prediction moment,

[0083] First offset information, where the first offset information is used to indicate a time offset of the first predicted moment relative to the reference moment.

[0084] The prediction interval is used to indicate the time interval between two adjacent prediction moments.

[0085] 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.

[0086] In an optional embodiment 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 the 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.

[0087] For example, for the fifth configuration information, an IE as shown in Table 8 may be added to CSI-ReportConfig:

[0088] Table 8

[0089] Among them, nwtimeprediction represents network-side inference. The terminal reports the quality of the reference signal measured in CSI-ReportConfig, and the network side predicts it. uetimeprediction represents terminal-side inference. 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.

[0090] For example, for the fifth configuration information, an IE as shown in Table 9 may be added to CSI-ReportConfig:

[0091] Table 9

[0092] Among them, nwtimeprediction represents network-side inference, and the terminal reports the quality of the reference signal measured in CSI-ReportConfig. uetimeprediction represents terminal-side inference, and the start time of AI-based prediction is the first transmission time of the CSI resource set in a cycle configured by the current CSI-ReportConfig plus the time offset slotoffset, or the last transmission time of the CSI resource set in a cycle plus the time offset slotoffset, or the reporting time plus the time offset slotoffset. Starting from the prediction start time, the beam quality is predicted and reported for the next nrofBeamPrediction time intervals, with the prediction time interval being intervalofPrediction.

[0093] In an optional implementation manner of the present application, the reporting configuration is carried in Radio Resource Control (RRC) signaling.

[0094] FIG4 is a second flow chart of a method for configuring CSI reporting provided in an embodiment of the present application. As shown in FIG4 , the method for configuring CSI reporting includes the following steps:

[0095] Step 401: The network device sends a CSI reporting configuration to the terminal device, where 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.

[0099] 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

[0106] In an optional implementation manner of the present application, the third configuration information includes the following information:

[0107] Association information, where the association information is used to indicate a configuration identifier of the at least one associated CSI reporting configuration.

[0108] In an optional embodiment 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.

[0109] In an optional implementation manner of the present application, the CSI reporting configuration is also used to configure beam prediction information.

[0110] 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:

[0111] Prediction quantity, the prediction quantity is used to indicate the quantity at the prediction moment,

[0112] First offset information, where the first offset information is used to indicate a time offset of the first predicted moment relative to the reference moment.

[0116] In an optional implementation manner of the present application, the reporting configuration is carried in radio resource control RRC signaling.

[0117] The technical solutions of the embodiments of the present application are illustrated below with reference to specific examples.

[0118] Example 1

[0119] Referring to Figure 5, the base station has eight transmit beams and the terminal has four receive beams. The AI-based beam prediction method configures the CSI-ReportConfig resource set to include 8*4=32 reference signal / beam pairs, with a CSI resource set period of 160ms (1 time slot = 1ms).

[0120] Table 10 below shows the pattern-based measurement configuration:

[0121] Table 10

[0122] The CSI-ResourceConfigId in the CSI-ReportConfig specifies the resource location for the first transmission of the full CSI resource set within a cycle. The base station repeats the CSI resource set corresponding to the CSI-ResourceConfigId four times within a cycle, with the interval between two consecutive repetitions being intervalofRSset=20ms. The MeasurementPattern bitmap specifies the CSI resource IDs to be measured at four time points within the full CSI resource set, 0 to 7, 8 to 15, 16 to 23, and 24 to 31, respectively.

[0123] When inference is performed on the network side, the CSI reporting configuration is shown in Table 11:

[0124] Table 11

[0125] The terminal reports the RSRP of the CSI reference signal measured at four moments in a cycle. The network uses the RSRP results at these four moments as input to the AI ​​model and outputs the RSRP of all beam pairs for the next four moments. For example, if beam pairs 1, 1, 2, and 3 have the highest RSRP at moments 1, 2, 3, and 4 in the future, and the beam pairs are not overloaded, the base station instructs the terminal to transmit data using beam pairs 1, 1, 2, and 3 at moments 1, 2, 3, and 4 in the future, respectively.

[0126] When the terminal side is inferring, the CSI reporting configuration is as shown in Table 12:

[0127] Table 12

[0128] Starting from the time corresponding to the last CSI resource set in a cycle configured by the current CSI-ReportConfig, the time offsets of the four predicted time points relative to the last CSI resource set transmission time point in a cycle are 40ms, 80ms, 120ms, and 160ms, respectively. The terminal uses the RSRP results of the four configured measurement times as AI model input, outputs the RSRP of all beam pairs for the next four time points, and reports the sequence number and RSRP of the top K optimal beam pairs for each of the next four time points to the base station. For example, if beam pairs 1, 1, 2, and 3 have the highest RSRP at time points 1, 2, 3, and 4 in the future, and the beam pairs are not overloaded, the base station instructs the terminal to transmit data using beam pairs 1, 1, 2, and 3 at time points 1, 2, 3, and 4, respectively.

[0129] Example 2

[0130] 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).

[0131] Table 13 below shows the pattern-based measurement configuration:

[0132] Table 13

[0133] The CSI-ReportConfigs with ids 2, 3, and 4 are associated with the current CSI-ReportConfig with id 1. The resource sets of the CSI-ReportConfigs with ids 1, 2, 3, and 4 contain CSI reference signals with ids 0 to 31, 32 to 63, 64 to 95, and 96 to 127, respectively. Starting from the time corresponding to the CSI resource set in a period of the CSI-ReportConfig configured with id 1, the terminal measures the CSI resource sets of the CSI-ReportConfigs with ids 1, 2, 3, and 4 within a period, and makes predictions and reports based on these measurement results.

[0134] When inference is performed on the network side, the CSI reporting configuration is as shown in Table 14:

[0135] Table 14

[0136] The terminal reports the RSRP of the CSI reference signal of CSI-ReportConfig with id = 1 to 4 within one period of the CSI-ReportConfig configuration with id = 1. The network side uses the RSRP results of the four time moments (4 CSI-ReportConfig) as the input of the AI ​​model and outputs the RSRP of all beam pairs in the next four time moments. For example, if the RSRP of beam pairs 1, 1, 2, and 3 at the 1st, 2nd, 3rd, and 4th time moments in the future is the highest 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 time moments in the future, respectively.

[0137] When the terminal side is inferring, the CSI reporting configuration is as shown in Table 15:

[0138] Table 15

[0139] The AI-based prediction starts at the transmission time of the CSI resource set configured by the current CSI-ReportConfig with id = 1, plus a time offset of slotoffset = 100ms. Starting from the prediction start time, the beam quality is predicted and reported for the next four moments, with a prediction interval of 40ms.

[0140] The terminal uses the RSRP results of the four configured measurements (4 CSI-ReportConfigs) as AI model input, 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.

[0141] Example 3

[0142] Referring to Figure 7, the base station has eight transmit beams and the terminal has four receive beams. The AI-based beam prediction method configures the CSI-ReportConfig resource set to include 8*4=32 reference signal / beam pairs, with a CSI resource set period of 20ms (1 time slot = 1ms).

[0143] Table 16 below shows the pattern-based measurement configuration:

[0144] Table 16

[0145] The CSI-ResourceConfigId in the CSI-ReportConfig specifies the resource location of the full set of CSI resources. The MeasurementPattern bitmap specifies the CSI resource IDs 0 to 7, 8 to 15, 16 to 23, and 24 to 31 to be measured for each of the four patterns in the full set. The terminal measures the four patterns in turn at different intervals / times. The reporting period is 160ms.

[0146] When inference is performed on the network side, the CSI reporting configuration is as shown in Table 17:

[0147] Table 17

[0148] The terminal reports the RSRP of the CSI reference signal measured at multiple moments within a reporting period. The network uses the RSRP results at some of these moments as input to the AI ​​model and outputs the RSRP of all beam pairs for the next four moments. For example, if beam pairs 1, 1, 2, and 3 have the highest RSRP at moments 1, 2, 3, and 4 in the future, and the beam pairs are not overloaded, the base station instructs the terminal to transmit data using beam pairs 1, 1, 2, and 3 at moments 1, 2, 3, and 4 in the future, respectively.

[0149] When the terminal side is inferring, the CSI reporting configuration is as shown in Table 18:

[0150] Table 18

[0151] The AI-based prediction starts at the reporting time plus a time offset (slotoffset) of 20ms. Starting from the prediction start time, the beam quality is predicted and reported for the next four moments, with prediction intervals of 40ms.

[0152] 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.

[0153] It should be noted that the above scheme is illustrated using 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.

[0154] 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 thereto. The above scheme can also be used for CSI prediction and network energy saving.

[0155] 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.

[0156] In the existing solution, a CSI resource set of a CSI-ReportConfig is configured with a maximum of 64 reference signals. The CSI reporting configuration method provided in the embodiment of the present application can be applied to the situation where the total set of reference signals to be measured is greater than 64.
