[0042] For ease of description, a base station is taken as an example of an access network device in the following description. In the following description, "if", "in the case of" and "when" can be used interchangeably without causing confusion.
[0043] The scenarios of the embodiments of the present application are described below by way of examples, but the present application is not limited thereto.
[0044] FIG. 1 is a schematic diagram of a communication system of an embodiment of the present application, which schematically illustrates a case taking a terminal device and a network device as examples. As shown in FIG. 1, the communication system 100 can include a network device 101, a terminal device 102 and a terminal device 103. For simplicity, FIG. 1 only takes two terminal devices and one network device as examples for illustration, but the embodiments of the present application are not limited thereto.
[0045] In the embodiments of the present application, the network device 101, the terminal device 102 and the terminal device 103 can perform existing services or future implementable services transmission. For example, these services can include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable and low-latency communication (URLLC) and related communication of reduced capability terminal devices, etc.
[0046] Among them, the terminal devices 102 and 103 can be in an RRC_IDLE state, or an RRC_INACTIVE state or an RRC_CONNECTED state, and the terminal devices 102 and 103 can also communicate with the network device 101. For example, taking the terminal device 102 as an example, the terminal device 102 can send data to the network device 101, or can perform data retransmission. The network device 101 can send a paging message to the terminal device 102, and can also send data to the terminal device 102, and the terminal device 102 receives the data sent by the network device 101. In addition, different terminal devices can also communicate with each other, for example, the terminal device 102 and the terminal device 103 can exchange data.
[0047] It is worth noting that FIG. 1 shows that the terminal device 102 and the terminal device 103 are both within the coverage of the network device 101, but the present application is not limited thereto. The terminal device 102 and the terminal device 103 can both be outside the coverage of the network device 101, or one of the terminal device 102 and the terminal device 103 is within the coverage of the network device 101 and the other is outside the coverage of the network device 101.
[0048] In embodiments of the present application, one or more AI / ML models can be configured and run in the network device and / or the terminal device. The AI / ML models can be used for various signal processing functions for wireless communication, such as CSI prediction, CSI compression, beam prediction, positioning management, etc.; the present application is not limited thereto.
[0049] Regarding the CSI prediction sub-use case, there are relevant contents as shown in Table 1 and Table 2:
[0050] Table 1
[0051] Table 2
[0052] For AI / ML-based CSI prediction, in order to obtain good CSI prediction accuracy, the consistency of the training and inference of the AI / ML model needs to be ensured. This means that, in the training data collection phase, the configurations, auxiliary information, or additional conditions on the terminal side and the network side must be consistent with the configurations, auxiliary information, or additional conditions in the inference phase. When the corresponding information in the training phase and the inference phase is inconsistent, the input distribution of the AI / ML model will drift, and the AI / ML model cannot work in the best state.
[0053] On the other hand, compared with a universal AI / ML model, a local AI / ML model can generally obtain better performance and lower complexity. In order to train a local AI / ML model or obtain the local gain of a local AI / ML model, we must label the training data. Training AI / ML models using different categories of training data can help obtain the local gain of the AI / ML model.
[0054] Therefore, for the collection of training data, in addition to the data related to the model input and the model output (label / ground truth) that needs to be collected, we also need to collect the configuration information, auxiliary information, and additional conditions on the network side and the terminal side.
[0055] In embodiments of the present application, AI / ML can also be referred to as AI / ML model, AI / ML method, AI / ML unit, AI / ML functionality, or similar names of AI / ML elements.
[0056] In the embodiments of the present application, the term "true value" can be replaced with similar names such as "label", "ground truth", "actual value", and the like.
[0057] Embodiments of the first aspect
[0058] The embodiments of the present application provide an information processing method, which is described from the terminal device side. FIG. 2 is a schematic diagram of an information processing method according to an embodiment of the present application. As shown in FIG. 2, the method comprises:
[0059] 201: The terminal device receives CSI resource configuration information and / or CSI reporting configuration information from the network device; and
[0060] 202: The terminal device reports training data for an AI / ML model according to the CSI resource configuration information and / or the CSI reporting configuration information.
[0061] It is worth noting that the above FIG. 2 only schematically illustrates the embodiments of the present application, but the present application is not limited thereto. For example, the execution order between the operations can be appropriately adjusted, and in addition, some operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications according to the above description, and the present application is not limited to the above FIG. 2.
[0062] According to the above embodiments, the terminal device receives CSI resource configuration information and / or CSI reporting configuration information from the network device, and reports training data for an AI / ML model according to the CSI resource configuration information and / or the CSI reporting configuration information. Thus, the training data for the AI / ML model can be collected, which helps to improve the accuracy and performance of the AI / ML model.
[0063] In some embodiments, the UE can use an artificial intelligence (AI) and / or machine learning (ML) based model (AI / ML model) for CSI prediction. For example, the UE can use the AI / ML model to predict one or more CSI-related information (output information, which can be referred to as CSI for short) at one or more future time instants according to one or more CSI-related information (input information, which can be referred to as CSI for short). Thus, at the one or more future time instants, the network device does not need to send CSI-RS to the terminal device, thereby reducing signaling overhead and helping to save energy on the network side; or the terminal device does not need to measure the CSI-RS or report the CSI at the one or more future time instants, thereby reducing signaling overhead and helping to save energy on the terminal side; or the network device uses the one or more future time instants CSI-related information for downlink PDSCH transmission, which reduces the performance loss caused by the aging of the feedback CSI.
[0064] In some embodiments, the UE can utilize the AI / ML model to predict L second CSI-related information from K first CSI-related information, where K and L are integers greater than or equal to 1. For example, K = 4 and L = 2, the UE predicts the second CSI-related information at time t+2△ and t+4△ from the first CSI-related information at time t-3△, t-2△, t-△ and t, where △ is greater than 0.
[0065] The first CSI-related information and the second CSI-related information can be a channel matrix and / or an eigenvector.
[0066] The channel matrix is, for example, a matrix used to describe the characteristics of a transmission channel. The channel matrix can generally be used to describe the attenuation and / or distortion of a transmitted signal in the channel. The channel matrix can be obtained by transmitting a reference signal and performing channel estimation.
[0067] The eigenvector is, for example, a vector obtained by matrix decomposition of the channel matrix, such as SVD (singular value decomposition) or EVD (eigenvalue decomposition), etc. In some embodiments, multiple layers of precoding vectors can be combined into a precoding matrix. In the embodiments of the present application, the terms “eigenvector” and “precoding vector” can be replaced with each other.
[0068] The present application is not limited thereto, and the first CSI-related information (input information) and the second CSI-related information (output information) can also be other forms of information capable of representing the channel state.
[0069] In some embodiments, the AI / ML model can predict L channel matrices from K channel matrices; or the AI / ML model can predict L eigenvectors from K eigenvectors.
[0070] However, the present application is not limited thereto, for example, the AI / ML model can also predict L eigenvectors from K channel matrices, or predict L channel matrices from K eigenvectors. For another example, the input and / or output of the AI / ML model can also be a combination of channel matrices and eigenvectors. For example, the AI / ML model can predict a channel matrix from a channel matrix and an eigenvector, or predict an eigenvector from a channel matrix and an eigenvector, or predict a channel matrix and an eigenvector from a channel matrix, or predict a channel matrix and an eigenvector from an eigenvector, or predict a channel matrix and an eigenvector from a channel matrix and an eigenvector, etc.
[0071] In some embodiments, the training data of the AI / ML model can include at least one of the following: the input information of the model; the true value corresponding to the output information of the model; or the first information of the terminal device.
[0072] The input information of the model can include a channel matrix and / or an eigenvector. The input information can be generated according to a measurement result of a CSI-RS at a first time (which can also be referred to as a measurement time).
[0073] For example, in 202, the UE can measure the CSI-RS at one or more first times (for example, the aforementioned times t-3△, t-2△, t-△, t) according to the received CSI resource configuration information and / or CSI reporting configuration information, generate a channel matrix and / or an eigenvector according to the measurement result, and use the channel matrix and / or the eigenvector as the input information of the model. For ease of description, the CSI-RS corresponding to the input information of the model is referred to as a first CSI-RS, and the resource corresponding to the first CSI-RS is referred to as a first resource.
[0074] The real value corresponding to the output information of the model can include a channel matrix and / or an eigenvector. In an embodiment of the present application, the output information of the model is output information generated according to the input information of the model in a model inference process; and the real value corresponding to the output information of the model is the output information of the model in an ideal case. One of the purposes of training the AL / ML model is to expect that the output information of the AL / ML model is as close as possible to the real value corresponding to the output information.
[0075] The real value corresponding to the output information can be generated according to a measurement result of a CSI-RS at a second time (which can also be referred to as a prediction time).
[0076] For example, in 202, the UE can measure the CSI-RS at one or more second times (for example, the aforementioned times t+2△, t+4△) according to the received CSI resource configuration information and / or CSI reporting configuration information, generate a channel matrix and / or an eigenvector according to the measurement result, and use the channel matrix and / or the eigenvector as the real value corresponding to the output information of the model. For ease of description, the CSI-RS corresponding to the output information of the model is referred to as a second CSI-RS, and the resource corresponding to the second CSI-RS is referred to as a second resource.
[0077] In some embodiments, the first information of the terminal device can also be referred to as assistance information or additional condition of the terminal device.
[0078] The first information of the terminal device can include at least one of the following: antenna configuration information of the terminal device, movement speed information of the terminal device, or time information expected by the terminal device.
[0079] Since the real values corresponding to the input information and the output information of the model are usually related to the first information, by including the first information in the training data, the first information can be used as a label (also referred to as "mark", "index", and the like) of the training data, thereby ensuring the consistency of the model training and the model inference, i.e., the first information in the model training phase can be kept consistent with the first information in the model inference phase. Thus, the prediction accuracy of the AI / ML model can be improved.
[0080] On the other hand, by including the first information in the training data, the real values corresponding to the input information and / or the output information of the model can be classified according to the first information. Thus, according to the classified training data, the AI / ML model corresponding to each classification can be trained, which helps to improve the accuracy of the AI / ML model, reduce the complexity of the model training, and obtain better performance.
[0081] In the model inference phase, the network device and / or the terminal device can perform LCM (Life-Cycle Management) operations such as model selection / model activation / model deactivation / model switching / rollback according to the classification label.
[0082] For example, when the current first information and / or second information is consistent with the classification label of the first model (or the first information and / or second information corresponding to a certain model), the first model should be selected or activated; or when the current first information and / or second information is inconsistent with the classification label of the second model (or the first information and / or second information corresponding to a certain model), the second model should be deactivated.
[0083] For another example, when the current first information and / or second information is inconsistent with the classification label of the current first model (or the first information and / or second information corresponding to a certain model), and the current first information and / or second information is consistent with the classification label of the second model (or the first information and / or second information corresponding to a certain model), the first model can be switched to the second model.
[0084] For another example, when there is no model consistent with the current first information and / or second information, the AI / ML model / function can be rolled back to a non-AI / ML method (i.e., a traditional method) for corresponding processing.
[0085] In some embodiments, the antenna configuration information of the terminal device can include at least one of: a number of horizontal direction panels and a number of vertical direction panels; a horizontal direction panel spacing and a vertical direction panel spacing; a number of horizontal direction antennas within a panel and a number of vertical direction antennas within a panel; a horizontal direction antenna spacing within a panel and a vertical direction antenna spacing within a panel; a mapping relationship between an antenna and a TxRU; or an antenna polarization direction. The application is not limited thereto, and the antenna configuration information of the terminal device can also include other information.
[0086] In some embodiments, the time information expected by the terminal device can include at least one of: first time information for performing CSI-RS measurement, second time information for performing CSI prediction, or an interval between the first time for performing CSI-RS measurement and the second time for performing CSI prediction.
[0087] The first time information can include a number of times of performing CSI-RS measurement and / or an interval. The number of times of performing CSI-RS measurement can refer to the number of channel matrices and / or eigenvectors included in the input information in one inference process. The interval of performing CSI-RS measurement can refer to the time interval of the CSI-RS corresponding to two adjacent channel matrices and / or eigenvectors in the input information. Taking the channel matrices at four time points t-3△, t-2△, t-△, t as an example, and predicting the channel matrices at two time points t+2△, t+4△, the number of times of performing CSI-RS measurement is K=4, and the interval of performing CSI-RS measurement is△.
[0088] The second time information can include a number of predicted CSIs and / or an interval. The number of predicted CSIs can refer to the number of channel matrices and / or eigenvectors included in the output information in one inference process. The interval of predicted CSIs can refer to the time interval of the CSI-RS corresponding to two adjacent channel matrices and / or eigenvectors in the output information. Taking the channel matrices at four time points t-3△, t-2△, t-△, t as an example, and predicting the channel matrices at two time points t+2△, t+4△, the number of predicted CSIs is L=2, and the interval of performing CSI-RS measurement is 2△.
[0089] The number of times of performing CSI-RS measurement can be the same as or different from the number of predicted CSIs, and the interval of performing CSI-RS measurement can be the same as or different from the interval of predicted CSIs.
[0090] In some embodiments, when there are multiple first moments for performing CSI-RS measurement and / or second moments for performing CSI prediction, the interval between the first moment and the second moment can be expressed as the interval between the last first moment and the first second moment. Taking the channel matrices at moments t-3Δ, t-2Δ, t-Δ, and t as an example, predicting the channel matrices at moments t+2Δ and t+4Δ, the interval between the first moment and the second moment is 2Δ. The present application is not limited to this, and the interval can be expressed as the interval between any first moment and any second moment.
[0091] In some embodiments, when classifying and / or labeling training data, the second information of the network device may also be referenced, or the first information of the terminal device and the second information of the network device may be referenced. In some embodiments, the second information of the network device may also be referred to as auxiliary information or additional conditions of the network device.
[0092] In some embodiments, the second information includes at least one of the following: antenna configuration information of the network device, scenario information of the network device, reference signal period, cell / site identification, carrier frequency, frequency domain granularity, or subcarrier spacing.
[0093] In some embodiments, the antenna configuration information of the network device may include at least one of the following: the number of horizontal panels and the number of vertical panels; the horizontal panel spacing and the vertical panel spacing; the number of horizontal antennas within the panel and the number of vertical antennas within the panel; the horizontal antenna spacing within the panel and the vertical antenna spacing within the panel; the mapping relationship between the antenna and the TxRU; or the antenna polarization direction.
[0094] In some embodiments, the scene information of the network device may include: indoor or outdoor, and / or line-of-sight or non-line-of-sight.
[0095] In some embodiments, the frequency domain granularity may include the number of PRBs (Physical Resource Blocks) in the subband. The present application is not limited thereto, and the frequency domain granularity may also include other information.
[0096] In some embodiments, the classification and / or labeling of training data may be performed on the terminal side or on the network side. For example, the UE includes first information in the reported training data, and the network device may classify and / or label the training data based on the first information of the UE and / or the second information of the network device. For another example, the UE receives second information sent by the network device, and the UE may classify and / or label the training data based on the first information and / or the second information, and report the classified and / or labeled training data.
[0097] The following is an exemplary description of the reference signal and reporting configuration used for training data collection.
[0098] In some embodiments, the CSI resource configuration information may be used to configure one or more CSI-RS resources.
[0099] The period or time interval of the CSI-RS resources can be configured based on information about the AI / ML model. For example, the period or time interval of the CSI-RS resources can be configured to be the same as the period or time interval of the training data used by the AI / ML model during training. This ensures the validity and reliability of the collected training data. Alternatively, the period or time interval of the CSI-RS resources can be configured to be the same as the period or time interval of the input data used by the AI / ML model during inference. This ensures consistency between AI / ML model training and inference.
[0100] For example, the training data used by the AI / ML model during training can be of equal period or equally spaced time domain. In this case, the CSI-RS resources include at least one of the following: periodic CSI-RS resources, semi-persistent CSI-RS resources, or aperiodic CSI-RS burst resources with equal time domain intervals.
[0101] However, the present application is not limited thereto, and the periodicity or time domain interval of the CSI-RS resources may be smaller than the periodicity or time interval of the training data used in the training process or the input data used in the inference process. In other words, part of the CSI-RS resources configured by the CSI resource configuration information is used for collecting training data. For example, the periodicity or time interval of the training data or input data may be an integer multiple of the periodicity or time domain interval of the CSI-RS resources. Thus, during the training data collection phase, the UE may perform measurements on part of the CSI-RS resources.
[0102] In some embodiments, the CSI-RS resources may be configured according to at least one of the following: a scenario of the network device, a moving speed of the terminal device, or a configuration desired by the terminal device.
[0103] The number of moments and / or intervals of CSI-RS resources can be configured based on at least one of the above information. For example, when the terminal device is moving at a low speed, the time domain correlation of CSI is large. In this case, the AI / ML model can use fewer first CSI-related information or information with larger time domain intervals to predict second CSI-related information; and / or the AI / ML model can predict more second CSI-related information or information with larger time domain intervals based on the first CSI-related information. Therefore, when collecting training data, less input information and / or input information with larger time domain intervals can be collected, and / or more output information and / or output information with larger time domain intervals and / or output information with larger time domain intervals from the input information can be collected. That is, the number of measurement moments for CSI-RS resources can be reduced, and / or the measurement moment intervals for CSI-RS resources can be increased, and / or the number of prediction moments for CSI-RS resources can be increased, and / or the prediction moment intervals for CSI-RS resources can be increased, and / or the interval between the measurement moments for CSI-RS resources and the prediction moments for CSI-RS resources can be increased.
[0104] On the contrary, when the terminal device moves faster, the channel correlation is poor. In this case, the AI / ML model needs to use more first CSI-related information or smaller time domain intervals to predict the second CSI-related information; and / or the AI / ML model can predict fewer second CSI-related information or smaller time domain intervals based on the first CSI-related information. Thus, the number of measurement moments of CSI-RS resources can be increased, and / or the measurement moment interval of CSI-RS resources can be reduced, and / or the number of prediction moments of CSI-RS resources can be reduced, and / or the prediction moment interval of CSI-RS resources can be reduced, and / or the interval between the measurement moment of CSI-RS resources and the prediction moment of CSI-RS resources can be reduced.
[0105] Similarly, the number of time instants and / or intervals of CSI-RS resources can also be configured based on the scenario of the network device (e.g., indoor or outdoor, and / or line-of-sight or non-line-of-sight). For example, when the scenario is indoors or line-of-sight, the time domain correlation of CSI is relatively good, while when the scenario is outdoor or non-line-of-sight, the time domain correlation of CSI is relatively poor.
[0106] In addition, the number of moments and / or intervals of the CSI-RS resources may also be configured according to the configuration expected by the terminal device. The configuration expected by the terminal device may include, for example, the moment information expected by the terminal device. For example, the number of moments and / or intervals of the CSI-RS resources may be configured to be the same as the moment information expected by the terminal device. Alternatively, the number of moments of the CSI-RS resources may be configured to be a greater number than the number of moments expected by the terminal device, and / or the interval of the CSI-RS resources may be configured to be a smaller number than the interval expected by the terminal device, and the terminal device may select a portion of the CSI-RS resources from the configured CSI-RS resources for the collection of training data.
[0107] In some embodiments, the CSI-RS resources used for reporting training data can also be used for acquiring and / or reporting channel state information (CSI), i.e., legacy CSI acquisition and / or reporting. In other words, the reference signals used for training data collection can be associated with layer 1 CSI reporting. For example, layer 1 CSI reporting can include PMI / RI / CQI / RSRP, etc. This means that the reference signals used for training data collection can be used for both legacy CSI measurement and reporting.
[0108] In some embodiments, the CSI-RS resources used for reporting training data can also be used for model performance monitoring. That is, the CSI-RS resources can be used simultaneously for AI / ML model performance monitoring and training data reporting. In other words, the reference signal used for training data collection can be used for AI / ML model performance monitoring.
[0109] In some embodiments, the UE may report training data based on the results of the performance monitoring of the AI / ML model. For example, when the performance monitoring result of the model is lower than a first threshold, the training data is reported; and / or, when the performance monitoring result of the model is higher than or equal to the first threshold, the training data is not reported. Thus, the reported training data corresponds to the situation where the performance of the AI / ML model is poor, that is, the situation where training needs to be focused, so that training data can be collected in a targeted manner, which helps to improve the performance of the AI / ML model through training.
[0110] The present application is not limited thereto. When the performance monitoring result of the model is higher than the second threshold, the training data is reported; and / or when the performance monitoring result of the model is lower than or equal to the second threshold, the training data is not reported. Thus, the reported training data corresponds to the situation where the performance of the AI / ML model is better. By training the model based on the above training data, the performance of the AI / ML model is improved.
[0111] In some embodiments, the second threshold may be a value greater than the first threshold.
[0112] In some embodiments, the first threshold and / or the second threshold may be predefined or network configured.
[0113] In some embodiments, the CSI-RS resources may include a first resource corresponding to a first CSI-RS and a second resource corresponding to a second CSI-RS. As described above, the measurement result of the first CSI-RS is used to generate input information of the AI / ML model, and the measurement result of the second CSI-RS is used to generate a true value corresponding to the output information of the AI / ML model.
[0114] The first resource and the second resource may be configured in various ways.
[0115] For example, the first resource and the second resource may be configured separately. For example, the network device may indicate which CSI-RS resources are the first resource and which CSI-RS resources are the second resource.
[0116] The first resource is associated with the second resource. For example, the network device may associate the first resource with the second resource through signaling, such as by performing resource association through a new IE during RRC configuration. Alternatively, the terminal device may associate the first resource with the second resource based on desired time information.
[0117] For another example, the first resource and the second resource may be jointly configured. For example, the network device may not explicitly distinguish between the first resource and the second resource. For example, the network device may configure CSI-RS resources for a period, and the terminal device may select the first resource and the second resource from the CSI-RS resources of the period based on desired time information.
[0118] In some embodiments, the measurement results of the first CSI-RS and the second CSI-RS may correspond to the same receive beam (Rx beam). This eliminates the impact of different receive beams on the measurement results, reduces the variables in the training data, and simplifies the training process. The present application is not limited to this, and the measurement results of the first CSI-RS and the second CSI-RS may also correspond to different receive beams.
[0119] In some embodiments, the CSI reporting configuration information and / or the CSI resource configuration information may include first indication information for instructing the collection and / or reporting of training data. Thus, after receiving the first indication information, the UE may collect and / or report the training data.
[0120] In some embodiments, the first indication information can be displayed by an indication, for example, by the appearance or absence of the first indication information, or a value, to indicate whether to report the training data. For example, when the first indication information appears in the CSI reporting configuration information and / or the CSI resource configuration information, it indicates that the UE reports the training data; when the first indication information is absent in the CSI reporting configuration information and / or the CSI resource configuration information, it indicates that the UE does not report the training data; and vice versa. For another example, the first indication information is indicated by 1 bit: when the 1 bit information takes the value 1, it indicates that the UE reports the training data; when the 1 bit information takes the value 0, it indicates that the UE does not report the training data; and vice versa. The present application is not limited to this, and the first indication information can also be implicitly indicated, for example, in the case of configuring the reporting information related to the training data or the resources related to the training data, the training data is reported by default, otherwise the training data is not reported.
[0121] In some embodiments, the training data can be reported in various ways.
[0122] In some embodiments, the training data can be reported by non-layer 1 signaling, for example, layer 3 signaling, etc. In this case, the first indication information can be carried on the radio resource control (RRC) signaling.
[0123] In some embodiments, the training data can be reported by layer 1 signaling, for example, uplink control information (UCI), etc. In this case, the first indication information can be carried on at least one of the following: radio resource control (RRC) signaling, medium access control layer control element (MAC CE), or downlink control information (DCI).
[0124] In some embodiments, the training data can be reported once, or divided into multiple times for reporting.
[0125] For example, the corresponding real values of the input information and the output information can be jointly reported. That is, in one reporting, both the input information and the output information are included.
[0126] For example, in the joint reporting, the corresponding real values of the input information and the output information can be jointly reported once as a whole. That is, the channel matrix / eigenvector is reported once after the reference signal transmission is completed.
[0127] Taking the prediction of the channel matrices at t+2△ and t+4△ based on the channel matrices at t-3△, t-2△, t-△ and t as an example, the channel matrices obtained by measuring the CSI-RS at t-3△, t-2△, t-△ and t and the channel matrices obtained by measuring the CSI-RS at t+2△ and t+4△ can be reported to the network device at one time.
[0128] The present application is not limited thereto, and the input information and the output information can also be reported in multiple times in joint reporting.
[0129] For example, the corresponding true values of the input information and the output information can be reported independently. That is, the input information is reported in one time, and the output information is not reported; or the output information is reported in one time, and the input information is not reported.
[0130] For example, when the input information is reported independently, the input information can be reported as a whole in one time; when the output information is reported independently, the corresponding true values of the output information can be reported as a whole in one time.
[0131] Taking the prediction of the channel matrices at t+2△ and t+4△ based on the channel matrices at t-3△, t-2△, t-△ and t as an example, the channel matrices obtained by measuring the CSI-RSs at t-3△, t-2△, t-△ and t can be reported in one time; the channel matrices obtained by measuring the CSI-RSs at t+2△ and t+4△ can be reported in another time.
[0132] The present application is not limited thereto, and the input information can also be reported in multiple times. For example, the input information can include the measurement results (i.e., multiple channel matrices and / or eigenvectors) of the CSI-RSs at multiple first time points, in which case, the measurement results can be reported in multiple times.
[0133] Taking the prediction of the channel matrices at t+2△ and t+4△ based on the channel matrices at t-3△, t-2△, t-△ and t as an example, the channel matrices at t-3△, t-2△, t-△ and t can be reported in four times respectively. For example, the UE reports the channel matrix at t-3△ after completing the measurement of the CSI-RS at t-3△, i.e., the channel matrix at t-3△; the UE reports the channel matrix at t-2△ after completing the measurement of the CSI-RS at t-2△, i.e., the channel matrix at t-2△; and so on. That is, the channel matrix / eigenvector can be reported in multiple times after each time point during the transmission of the reference signal.
[0134] The output information can also be reported in multiple times. For example, the output information can include the measurement results (i.e., multiple channel matrices and / or eigenvectors) of the CSI-RSs at multiple second time points, in which case, the measurement results can be reported in multiple times.
[0135] Taking the channel matrix at t+2△ and t+4△ as an example, which is predicted according to the channel matrix at t-3△, t-2△, t-△, and t, the channel matrix at t+2△ and t+4△ can be reported twice. For example, the UE reports the channel matrix at t+2△ after completing the measurement of the CSI-RS at t+2△, that is, the channel matrix at t+2△; the UE reports the channel matrix at t+4△ after completing the measurement of the CSI-RS at t+4△, that is, the channel matrix at t+4△.
[0136] The above exemplary describes the reporting manner of the input information and the output information. In the case where the first information is included in the training data, one or more times of reporting can be performed.
[0137] For example, the input information, the output information, and the first information can be jointly reported; or, the input information, the output information, and the first information can be independently reported; or, any two of the input information, the output information, and the first information can be jointly reported, and the other one can be independently reported.
[0138] In some embodiments, in the case where multiple channel matrices and / or eigenvectors are reported at one time, the complete content of each channel matrix and / or eigenvector can be reported in the one-time reporting. For example, the complete content of each channel matrix and / or eigenvector is concatenated, and the concatenated result is reported.
[0139] The present application is not limited thereto. In the case where multiple channel matrices and / or eigenvectors are reported at one time, the multiple channel matrices and / or eigenvectors can be appropriately compressed in order to reduce the signaling overhead.
[0140] For example, the complete content of at least one channel matrix and / or eigenvector is reported in the one-time reporting, and the channel matrix and / or eigenvector is taken as a reference channel matrix and / or reference eigenvector. For other channel matrices and / or eigenvectors, the difference with the reference channel matrix and / or reference eigenvector can be reported.
[0141] For another example, the reported training data is compressed by using an AI / ML model, and the like.
[0142] The above embodiments are only exemplary descriptions of the embodiments of the present application, but the present application is not limited thereto. Appropriate modifications can be made on the basis of the above embodiments. For example, each of the above embodiments can be used alone, or one or more of the above embodiments can be combined.
[0143] According to the above embodiments, the terminal device receives the CSI resource configuration information and / or the CSI reporting configuration information from the network device, and reports the training data for the AI / ML model according to the CSI resource configuration information and / or the CSI reporting configuration information.
