Communication processing method, apparatus, device and readable storage medium

[0001] Cross-reference to Related Applications

[0002] The present application claims priority to Chinese Patent Application No. 202410677308.3, filed on May 29, 2024, the contents of which are incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] Embodiments of the present disclosure relate to the field of communication technology, in particular to a communication processing method, apparatus, device and readable storage medium. BACKGROUND

[0004] Existing research results show that artificial intelligence (AI) can obtain corresponding gain in the field of beam management under the existing design framework of the fifth generation mobile communication technology (5th Generation, 5G), and shows considerable application prospect. Wireless AI has been established in related technologies, and the research contents include three major use cases of channel state information (CSI) feedback, beam management, and positioning, AI model deployment, inference, and update, simulation evaluation methods, etc.

[0005] A typical use case of AI beam management is spatial beam prediction. AI-enabled spatial beam prediction can predict the L1-RSRP of all beam pairs (such as setA) by measuring the L1-RSRP of part of the beam pairs (such as setB), and select the optimal beam to reduce the terminal beam measurement overhead, as shown in FIG. 1.

[0006] The implementation method of AI-based spatial beam prediction is to first train 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 a certain time.

[0007] 1) For beam pair prediction, during training, the RSRP of a small number of beam pairs (setB) is input to the AI model (usually a neural network), the RSRP of all beam pairs (setA) is the label output by the AI model, and the parameters in the AI model are constantly updated by the gradient descent algorithm until the error between the AI model output and the label (which can be measured by the normalized mean square error (NMSE)) is less than a threshold value, at which time the model converges and has good prediction ability.

[0008] 2) For transmit beam prediction, under certain receive beam assumptions, during training, the RSRP of a small number of transmit beams is input to the AI model, and the RSRP of all transmit beams is the label output by the AI model, and the parameters in the AI model are constantly updated by the gradient descent algorithm until the error between the AI model output and the label is less than a threshold value.

[0009] After the AI model is trained, when the terminal side reasons, as shown in FIG. 2: Assuming that the base station has 64 transmit beams and the terminal has 4 receive beams. The base station configures 8*4=32 channel state information reference signals (CSI-RSs) (setB) with a reference signal period of 80 ms, and the terminal measures the L1-RSRP of 32 beam pairs at each time. The terminal inputs the measured 32 L1-RSRPs to the AI model, predicts the L1-RSRP of 256 beam pairs based on the AI model, and reports the CRI and L1-RSRP of the K best beam pairs in the beam pair set setA to the base station. The base station scans the K best beam pairs or a subset thereof, and according to the measured RSRP value and beam pair load, etc., instructs a certain beam pair to communicate with the terminal.

[0010] The existing CSI reporting framework can only be configured with a periodic or semi-persistent resource set, which has at most 64 RS. After the terminal reports the TopK beams each time, the base station needs to configure different TopK beams for scanning, and according to the existing CSI reporting framework, the base station needs to frequently reconfigure the radio resource control (RRC) parameters to update the TopK beam resource set, which has large signaling overhead and latency.

Rather, the word “exemplary” or “for example” is used to present related concepts in a specific manner.

[0050] Referring to FIG. 3, a Medium Access Control (MAC) Control Element (CE) for activating / deactivating a semi-persistent resource set is shown, where A / D:1 represents activation and 0 represents deactivation.

[0051] The semi-persistent CSI-RS reporting on the physical uplink control channel (PUCCH) needs a MAC CE to activate one CSI reporting configuration (CSI-ReportConfig) as shown in FIG. 4, and the CSI-ReportConfig configures the PUCCH resource and the periodic offset of the reporting.

[0052] The semi-persistent CSI-RS reporting on the physical uplink shared channel (PUSCH) needs some fields of the downlink control information (DCI) 0_1 / 0_2 to take special values to indicate the activation / deactivation of one trigger state, and one trigger state contains one CSI-ReportConfig.

[0053] The aperiodic CSI-RS reporting on the PUSCH needs RRC to configure 128 trigger states, and the MAC CE+DCI to trigger one trigger state at a time, and one trigger state contains at most 16 CSI-ReportConfig.

[0054] Referring to FIG. 5, the embodiment of the disclosure provides a communication processing method applied to a terminal, and the specific steps include:

[0058] Step 52: measuring at least one reference signal in the first reference signal set and sending a first CSI report, the first CSI report including indexes and / or signal qualities of reference signals in a fourth reference signal set, the fourth reference signal set being a subset of the second reference signal set;

[0061] Optionally, the signal quality of the first reference signal set is used by the terminal to infer the signal quality of the reference signals in the second reference signal set through a model (such as an AI model or a Machine Learning (ML) model), which can be used to determine the indexes and / or signal qualities of the reference signals in the fourth reference signal set, i.e., the fourth reference signal set can be a subset of the second reference signal set, and the reference signals in the fourth reference signal set can be used by the terminal to perform actual measurements to obtain actual signal qualities (or actual measurement quantities).

[0062] Optionally, the fourth reference signal set includes one or more reference signals with the best signal quality in the second reference signal set, for example, the fourth reference signal set includes K reference signals, which are the K reference signals with the best signal quality in the second reference signal set, and K is greater than or equal to 1, i.e., the fourth reference signal set can be represented by TopK reference signals.

[0063] Optionally, the signal quality includes but is not limited to at least one of the following: Reference Signal Received Power (RSRP) and Signal to Interference plus Noise Ratio (SINR).

[0064] Step 53: measuring at least one reference signal in the fourth reference signal set or the fifth reference signal set or the third reference signal set;

[0069] For example, the fourth reference signal set comprises K reference signals with the best signal quality (e.g. the largest RSRP) among the reference signals in the second reference signal set.

[0070] For example, the determining the signal quality of the reference signals in the second reference signal set according to the signal quality of at least part of the reference signals in the first reference signal set comprises inferring the signal quality of the reference signals in the second reference signal set by using a model (e.g. an AI model or an ML model) on the signal quality of at least part of the reference signals in the first reference signal set.

[0071] In an embodiment of the present disclosure, the method further comprises:

[0072] receiving first information, the first information being used to indicate the fifth reference signal set.

[0073] For example, the fourth reference signal set comprises K reference signals, and the fifth reference signal set comprises K1 reference signals, and the first information is used to indicate that K1 reference signals among the K reference signals in the second reference signal set are used for CSI reporting, and the K1 reference signals are a subset of the K reference signals, and K1 is less than K.

[0074] The K1 reference signals can be used as the actual measurement reference signal set, i.e. the first information is used to indicate that the K1 reference signals among the K reference signals in the second reference signal set are used as the actual measurement reference signal set.

[0076] For example, if the nth bit of the bitmap is "1", the nth reference signal in the fourth reference signal set belongs to the fifth reference signal set; for another example, if CRI = n, the nth reference signal in the fourth reference signal set belongs to the fifth reference signal set.

[0077] In an embodiment of the present disclosure, the reference signals in the third reference signal set have the same spatial transmission filter as the reference signals in the fourth reference signal set or the fifth reference signal set.

[0086] The index of the reference signal can comprise an index of a reference signal in the fourth reference signal set, and the signal quality can comprise a signal quality of a reference signal in the fourth reference signal set.

[0087] For example, the index of the reference signal can be an index of K reference signals in the second reference signal set predicted by a model based on a signal quality of at least one reference signal in the first reference signal set, and the signal quality can be a signal quality of the K reference signals in the second reference signal set predicted by the model based on the signal quality of the at least one reference signal in the first reference signal set.

[0096] Optionally, the index of the reference signal comprises an index of a reference signal in the fourth reference signal set or the fifth reference signal set or the third reference signal set, for example, the index of the reference signal comprises an index of K1 reference signals in K reference signals in the second reference signal set.

[0097] Optionally, the signal quality comprises a signal quality of a reference signal in the fourth reference signal set or the fifth reference signal set or the third reference signal set, for example, the index of the reference signal comprises a RSRP of K1 reference signals in K reference signals in the second reference signal set.

[0098] In the present disclosure, after the terminal infers and reports an index and / or a signal quality of all or part of the K reference signals, the base station does not need to frequently reconfigure RRC parameters to configure the K reference signals, thereby reducing signaling overhead and latency of indicating the K reference signals.

[0103] Optionally, the first CSI report can be obtained by the terminal based on measurement of at least one reference signal in the first reference signal set, for example, the signal quality of the first reference signal set is used by the terminal to infer the signal quality of reference signals in the second reference signal set through a model (such as an AI model or an ML model), and the signal quality of the reference signals in the second reference signal set can be used to determine the indexes and / or signal qualities of reference signals in the fourth reference signal set, and the reference signals in the fourth reference signal set can be used by the terminal to obtain actual signal qualities (or actual measurement quantities) through actual measurement.
