The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0103] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0104] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only.

[0105] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0106] In the disclosed embodiments, in NR, especially when the communication frequency band is in frequency range 2, since the high-frequency channel attenuates rapidly, beam-based transmission and reception are required to ensure coverage.

[0107] In some traditional beam management processes, network devices configure a set of reference signal resources for beam measurement. The terminal measures the reference signal resources in this set. The terminal reports the identifiers (IDs) of some of the stronger reference signal resources, along with the corresponding layer 1 reference signal received power (L1-RSRP) and / or layer 1 signal to interference plus noise ratio (L1-SINR), to the network device.

[0108] In related art, it is assumed that the reference signal resource set configured by a network device includes X reference signals, each corresponding to a different transmit beam of the network device. For each reference signal, the terminal needs to use all receive beams to measure that reference signal. This results in the beam measurement quality corresponding to all receive beams. In some cases, one or more best beam measurement qualities and / or the beam identifier corresponding to the best beam measurement quality can be determined. Therefore, the number of beam pairs that the terminal needs to measure is G*H. Here, G represents the number of transmit beams of the network device, and H represents the number of receive beams of the terminal.

[0109] In some embodiments, an AI model and / or AI function is provided to implement beam prediction, wherein an AI function can be considered as one or more AI models that implement the same function and purpose.

[0110] In some embodiments, the AI ​​model used for beam prediction can be referred to as a beam prediction model. Of course, it can also be referred to as a beam prediction AI model, a prediction AI model, a predicted beam model, etc. This disclosure does not limit the names of such AI models.

[0111] In some implementations, when the beam prediction model uses spatial prediction, the terminal measures the L1-RSRP of set B and inputs the measured value into the beam prediction model. The beam prediction model can predict the L1-RSRP of the best beam and / or beam pair in set A, and / or the identifier of the best beam and / or beam pair in set A.

[0112] The relationship between set B and set A includes the following two types:

[0113] The first relationship is that set B is a subset of set A. For example, if set A contains 32 reference signal resources (each reference signal resource corresponds to a beam direction), then set B contains some of them, for example, set B contains 8 of the 32 reference signal resources.

[0114] The second relationship is that set B is a wide beam and set A is a narrow beam. For example, set A contains 32 reference signal resources (each reference signal resource corresponds to a beam direction, and the 32 reference signal resources cover a 120-degree direction). Set B contains another Y reference signal resources, for example, Y = 8. These Y reference signal resources also cover a 120-degree direction, that is, the beam direction of each reference signal resource in set B covers the beam directions of multiple reference signal resources in set A. It can be understood that the relationship between the 32 / Y reference signal resources in set A and the one reference signal resource in set B is QCL Type D.

[0115] It should be understood that the examples of the first and second relationships described above only describe the transmit beam case. When considering beam pairs consisting of transmit and receive beams, the terminal's receive beams must also be considered. For example, if there are 32 transmit beams and 4 receive beams, then set A consists of 32*4 beam pairs, and set B can consist of 32 beam pairs, 16 beam pairs, and so on.

[0116] In some embodiments, if the performance of the beam prediction model does not need to be monitored, assuming that the AI ​​model has been trained in advance, the network device only needs to periodically send the reference signal on the reference resource of set B (for example, the first period). The terminal then measures the L1-RSRP of the reference signal on the reference signal resource in set B and inputs it into the beam prediction model. This outputs the L1-RSRP corresponding to the reference signal resource of set A or the strongest one or more reference signal resource IDs among the 32 reference signal resources in set A.

[0117] In some embodiments, if it is necessary to monitor the performance of the beam prediction model, the network device is required to periodically send the reference signal on the reference signal resource of set A (for example, the second period). Then the terminal needs to measure the L1-RSRP of the reference signal on the reference signal resource of set B. For the terminal side model, the terminal inputs the measured L1-RSRP of the reference signal on the reference signal resource of set B into the beam prediction model, obtains the predicted beam information, and reports it to the network device; for the network side model, the terminal reports the measured L1-RSRP and / or identifier of the reference signal on the reference signal resource of set B to the network device, and the network device inputs the L1-RSRP and / or identifier of the reference signal on the reference signal resource of set B into the beam prediction model to obtain the predicted beam information. At the same time, the terminal also measures the L1-RSRP of the reference signals on all reference signal resources in set A, and reports the measured L1-RSRP and / or identifier of the reference signals on all reference signal resources in set A, and / or the L1-RSRP and / or identifier of the best L beams / beam pairs as the beam information obtained by the traditional method to the base station.

[0118] In various embodiments of the present disclosure, the terms "terminal-side model" and "AI model deployed on the terminal" can be used interchangeably. The terms "network device-side model" and "AI model deployed on the network device" can be used interchangeably.

[0119] In some implementations, when the beam prediction model uses time-domain prediction, the terminal measures the L1-RSRP at a historical time point, set B, and inputs this into the beam prediction model to predict the L1-RSRP at a future time point, set A. In addition to the two aforementioned relationships between set B and set A, there is another relationship in which set B and set A are identical.

[0120] When beam measurement is performed using methods described in related technologies, the base station also needs to transmit reference signals at future times. The terminal measures the reference signals at future times and reports the measured beam information to the network device. Specifically, the terminal needs to measure and report the beam information for all beams and / or beam pairs in set A to the network device.

[0121] In some related technologies, in order to reduce the number of beam pairs measured by the terminal, an AI model is used for beam prediction. For example, the terminal originally needs to measure a total of G*H beam pairs. When using the AI ​​model for beam prediction, for spatial domain beam prediction, the terminal only needs to measure a part of the G*H beam pairs. For example, measure 1 / 8, 1 / 4 of G*H beam pairs, etc. Then, the beam measurement quality of these beam pairs measured is input into the AI ​​model, and the AI ​​model can output the beam information of G*H beam pairs. For time domain beam prediction, the terminal can measure the beam measurement quality of beam pairs at historical times to predict the beam information of beam pairs at future times.

[0122] Of course, for the input and output of some AI models, it is also possible to not consider the beam quality or beam identification of the beam pair, but only consider the beam quality or beam identification of the downlink transmit beam. For example, an AI model based on a downlink beam, rather than an AI model based on a beam pair, is not limited in this disclosure.

[0123] It's clear that AI models have a specific lifecycle or scope of application. For example, some AI models are suitable for specific environments, such as suburban areas, urban areas, and indoor environments. Another example is that some AI models are suitable for rush hour, while others are suitable for specific time periods, such as during the sparse rush hour of work. Another example is that some AI models may be suitable for specific times and environments, such as on busy roads during the rush hour. Therefore, it's necessary to monitor the performance of AI models in real time. If the performance of an AI model falls short of expectations, it's necessary to promptly update or switch the model.

[0124] In some embodiments, different AI models also have different corresponding performance. For example, when the AI ​​model is used for spatial domain beam prediction, set B is a subset of set A. If the number of beams or beam pairs contained in set B is different, the accuracy of the beam information of set A predicted by the AI ​​model will be different. For another example, when the AI ​​model is used for time domain beam prediction, if the number of historical measurement times input or the number of future times output is different, the accuracy of the beam information output by the AI ​​model will also be different.

[0125] For different AI models, how to enable network devices to accurately activate models with different performance according to demand is an issue that is being studied.

[0126] FIG2 is a schematic diagram illustrating an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to a communication method for use in a communication system 100, the method comprising:

[0127] Step S2101 , the terminal 101 sends first information to the network device 102 .

[0128] In some embodiments, the network device 102 receives the first information sent by the terminal 101 .

[0129] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0130] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0131] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", and "parameter" can be used interchangeably.

[0132] In some embodiments, the first information includes the performance of an AI function or an AI model. The AI ​​function or AI model is deployed on the terminal side. The AI ​​function corresponds to one or more AI models.

[0133] In some embodiments, the performance of an AI function can be determined based on the performance of one or more AI models corresponding to the AI ​​function. For example, if the AI ​​function corresponds to multiple AI models, the performance of the AI ​​function can be the maximum, minimum, average, or a specified number of performance values ​​of the multiple AI models corresponding to the AI ​​function. For another example, the performance of the AI ​​function can also be a performance value range consisting of the performance values ​​of the multiple AI models corresponding to the AI ​​function.

[0134] In some embodiments, the network device may determine an AI function or AI model based on the received first information, and instruct the terminal to activate, deactivate, or perform other operations on the AI ​​function or AI model.

[0135] In some embodiments, the performance of the AI ​​function or AI model includes different types of performance.

[0136] This disclosure uses the use of AI functions or AI models for beam prediction as an example to illustrate their performance. However, AI functions or AI models are not limited to beam prediction. For example, they can also be used for CSI compression, CSI prediction, positioning, and other applications. This disclosure does not list all of these.

[0137] Among them, different types of performance can also be referred to as performance of different dimensions. The AI ​​function or AI model includes at least one of the following types: beam or beam pair prediction accuracy; beam or beam pair prediction accuracy with an L1-RSRP difference within a first threshold, the L1-RSRP difference is the difference between the measured L1-RSRP of the best predicted beam or beam pair and the measured L1-RSRP of the best beam or beam pair; L1-RSRP difference, the L1-RSRP difference is the difference between the measured L1-RSRP of the best predicted beam or beam pair and the measured L1-RSRP of the best beam or beam pair, wherein the L1-RSRP difference includes at least one of the following: the average value of the L1-RSRP difference, the cumulative distribution function of the L1-RSRP difference, the proportion of the L1-RSRP difference less than or equal to the second threshold, and the proportion of the L1-RSRP difference greater than the third threshold, wherein the L1-RSRP difference is the best predicted beam or beam pair. The method comprises the following steps: a first step of determining the difference between the measured L1-RSRP of the best predicted beam or beam pair and the measured L1-RSRP of the best predicted beam or beam pair; a predicted L1-RSRP difference, wherein the predicted L1-RSRP difference is the difference between the predicted L1-RSRP of the best predicted beam or beam pair and the measured L1-RSRP of the best predicted beam or beam pair, wherein the predicted L1-RSRP difference includes at least one of the following: an average value of the predicted L1-RSRP difference, a cumulative distribution function of the predicted L1-RSRP difference, a proportion of the predicted L1-RSRP difference less than or equal to a fourth threshold, and a proportion of the predicted L1-RSRP difference greater than a fifth threshold, wherein the predicted L1-RSRP difference is the difference between the predicted L1-RSRP of the best predicted beam or beam pair and the measured L1-RSRP of the best predicted beam or beam pair; terminal throughput; reference signal overhead; uplink control information overhead; and predicted delay.

[0138] In some embodiments, terms such as "uplink", "uplink", "physical uplink" can be interchangeable with each other, and terms such as "downlink", "downlink", "physical downlink" can be interchangeable with each other, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct link", "direct communication", "direct link communication" can be interchangeable with each other.

[0139] In some embodiments, the terms "downlink control information (DCI)", "downlink (DL) assignment", "DL DCI", "uplink (UL) grant", "UL DCI" and the like may be used interchangeably.

[0140] In some embodiments, the performance of the AI ​​function or AI model includes: beam or beam pair prediction accuracy.

[0141] For example, when using an AI model for beam prediction, if the predicted best K1 beams include the measured best beam, the prediction is accurate. Alternatively, if the predicted best beam is among the measured best K2 beams, the prediction is accurate. If the AI ​​model performs M beam predictions and N of them are correct, the prediction accuracy is N / M. K1 and K2 are positive integers, such as 1, 2, 3, 4, 5, and so on.

[0142] In some embodiments, the downlink transmit beam ID may be equivalent to a reference signal resource ID, such as a synchronization signal block (SSB) ID, a sounding reference signal (SRS) ID, or a channel state information reference signal (CSI-RS) ID. The downlink receive beam ID may be the receive beam ID of the terminal. The beam pair ID may be the ID corresponding to the combination of a downlink transmit beam and a downlink receive beam.

[0143] In some embodiments, terms such as "synchronization signal (SS)", "synchronization signal block (SSB)", "reference signal (RS)", "pilot", and "pilot signal" can be used interchangeably.

[0144] In some embodiments, the best beam may be the beam with the strongest L1-RSRP or L1-SINR.

[0145] In some embodiments, the performance of the AI ​​function or AI model includes: beam or beam pair prediction accuracy with an L1-RSRP difference within a first threshold. The L1-RSRP difference is the difference between the measured L1-RSRP of the best predicted beam or beam pair and the measured L1-RSRP of the best measured beam or beam pair.

[0146] For example, when using an AI model for beam prediction, if the difference between the measured L1-RSRP of the best predicted beam and the measured L1-RSRP of the measured best beam is less than a first threshold, the prediction is accurate. Then, if the AI ​​model is used to predict beams P times, and the difference between the measured L1-RSRP of the best predicted beams and the measured L1-RSRP of the measured best beam is less than the first threshold Q times, the prediction accuracy for beams or beam pairs with L1-RSRP differences within the first threshold is Q / P. The best predicted beam represents the best beam predicted by the AI ​​model. The measured L1-RSRP represents the L1-RSRP measured for the beam. That is, the measured L1-RSRP of the predicted best beam represents the best beam predicted by the AI ​​model and measured for that best beam. The measured best beam represents the best beam obtained through actual measurement. For example, the actual measurement may be to measure the L1-RSRP or L1-SINR of multiple beams respectively, and the beam with the largest L1-RSRP or L1-SINR is the best beam. Measuring the L1-RSRP of the best beam means obtaining the best beam through actual measurement, and measuring the L1-RSRP of the best beam.

[0147] In some embodiments, the first threshold may be, for example, 1 dB, and the beam or beam pair prediction accuracy for which the L1-RSRP difference is within the first threshold may be a beam or beam pair prediction accuracy for which the L1-RSRP difference is within 1 dB. The L1-RSRP difference is the difference between the measured L1-RSRP of the best predicted beam or beam pair and the measured L1-RSRP of the best measured beam or beam pair.

[0148] In some embodiments, the performance of the AI ​​function or AI model includes: L1-RSRP difference, which is the difference between the measured L1-RSRP of the best predicted beam or beam pair and the measured L1-RSRP of the best beam or beam pair before measurement.

[0149] In some embodiments, the L1-RSRP difference may be the average of the L1-RSRP differences. For example, an AI model is used to perform one or more predictions to obtain A best predicted beams, and these A best predicted beams are measured separately to obtain the measured L1-RSRPs of the A best predicted beams. The differences between the measured L1-RSRPs of the A best predicted beams and the measured L1-RSRP of the measured best beam are calculated separately, and the average is taken, which is the average of the L1-RSRP differences, or the L1-RSRP difference. The A best beams may be the A best beams obtained by performing a single prediction using the AI ​​model, or the A best beams obtained by performing multiple predictions using the AI ​​model.

[0150] In some embodiments, the L1-RSRP difference may be a cumulative distribution function of L1-RSRP differences. For example, the value of the cumulative distribution function of L1-RSRP differences at a fixed percentage point is the L1-RSRP difference.

[0151] In some embodiments, the L1-RSRP difference may be a value of a cumulative distribution function at 5%, for example, YdB.

[0152] In some embodiments, the L1-RSRP difference may be a ratio of L1-RSRP differences less than or equal to a second threshold. For example, if model AI is used to perform A predictions, and B of the predictions have L1-RSRP differences less than or equal to the second threshold, then the L1-RSRP difference is B / A.

[0153] In some embodiments, the L1-RSRP difference may be a ratio of L1-RSRP differences greater than a third threshold. For example, if the AI ​​model is used to perform C predictions, and D of the L1-RSRP differences are greater than the third threshold, then the L1-RSRP difference is D / C.

[0154] The term "greater than the third threshold" may also mean "greater than or equal to the third threshold," which is not limited in this disclosure. The first, second, and third thresholds in this disclosure may be set based on actual circumstances, and may be the same or different.

[0155] In some embodiments, the performance of the AI ​​function or AI model includes: a predicted L1-RSRP difference, where the predicted L1-RSRP difference is the difference between the predicted L1-RSRP of the best predicted beam or beam pair and the measured L1-RSRP of the best predicted beam or beam pair.

[0156] The predicted L1-RSRP represents the predicted L1-RSRP of a beam using the AI ​​model. That is, the predicted L1-RSRP of the best predicted beam or beam pair represents the best predicted beam predicted by the AI ​​model, and the L1-RSRP of that best predicted beam also predicted by the AI ​​model.

[0157] In some embodiments, the predicted L1-RSRP difference may be an average of the predicted L1-RSRP differences.

[0158] In some embodiments, the predicted L1-RSRP difference may be a cumulative distribution function of the predicted L1-RSRP difference.

[0159] In some embodiments, the predicted L1-RSRP difference may be a ratio of the predicted L1-RSRP difference values ​​that is less than or equal to a fourth threshold.

[0160] In some embodiments, the predicted L1-RSRP difference may be a ratio of the L1-RSRP difference greater than a fifth threshold.

[0161] The predicted L1-RSRP difference is the difference between the predicted L1-RSRP of the best predicted beam or beam pair and the measured L1-RSRP of the best predicted beam or beam pair.

[0162] In the present disclosure, the best predicted beam, the predicted best beam, and the predicted best beam have the same meaning and can be used interchangeably.

[0163] In some embodiments, the performance of the AI ​​function or AI model includes: terminal throughput. For example, the predicted optimal beam or beam pair and the SINR of the optimal beam or beam pair can be determined, and the capacity corresponding to each beam or beam pair can be calculated based on the Shannon capacity. The difference between the capacities corresponding to the two beams or beam pairs can be used as the average UE throughput difference.

[0164] In some embodiments, the terminal throughput may be an average throughput or a throughput at a fixed percentage of a cumulative distribution function, for example, the fixed percentage may be 5% or 95%.

[0165] In some embodiments, the performance of an AI function or AI model includes reference signal overhead, which refers to the amount of reference signal resources required by the AI ​​model.

[0166] Among them, the size of set B input to the AI ​​model and the number of historical measurement times during time domain beam prediction have an impact on the reference signal overhead.

[0167] In some embodiments, the performance of the AI ​​function or AI model includes: uplink control information overhead. If the AI ​​model is an AI model deployed on the network device side, the terminal needs to send the measurement results based on set B to the network device. The uplink control information overhead is the signaling overhead of sending the measurement results of set B.

[0168] In some embodiments, the performance of an AI function or AI model includes: predicted latency. For example, the unit of predicted latency can be milliseconds (ms). This means that multiple beam information measured at time A is input into the AI ​​model, and after the AI ​​model predicts the optimal beam at time B, the predicted latency is the difference between time A and time B. For example, the smaller the predicted latency, the better the performance of the AI ​​model.

[0169] In some embodiments, the first information may include an identifier of an AI function or an identifier of an AI model supported by the terminal. The identifier of the AI ​​function is used to identify the AI ​​function or to indicate the AI ​​function. The identifier of the AI ​​model is used to identify the AI ​​model or to indicate the AI ​​model.

[0170] In some embodiments, the first information may include an environment of an AI function supported by the terminal or an environment of an AI model.

[0171] In some embodiments, the environment may include an environment (condition) or an additional environment (additional condition), and the environment may represent the environment or condition to which the AI ​​model is applicable, or represent the characteristics of the AI ​​model. The environment of the AI ​​function or the environment of the AI ​​model includes the application environment of the AI ​​function or model. For example, the AI ​​function or AI model is used for beam prediction, for CSI compression, for CSI prediction, for positioning, etc. This disclosure does not give examples one by one. For another example, the AI ​​function or AI model is used for spatial beam prediction, or for time domain beam prediction.

[0172] The present disclosure uses the AI ​​function or AI model for spatial beam prediction as an example to illustrate the environment of the AI ​​function or AI model. The environment of the AI ​​function or AI model includes at least one of the following: the number of beams or beam pairs in the first beam set, the measurement value of the first beam set is used as the input of the AI ​​model; the beam pattern of the beams or beam pairs in the first beam set; the number of beams or beam pairs in the second beam set, wherein the output of the AI ​​model is used to obtain beam information in the second beam set; the beam pattern of the beams or beam pairs in the second beam set; the relationship between the first beam set and the second beam set; the content of the AI ​​model input; the content of the AI ​​model output; AI function or AI model performance monitoring information; auxiliary information; applicable deployment scenarios; applicable network equipment beam codebook; applicable terminal beam codebook; applicable terminal distribution information; the number of measurement instances input to the AI ​​model; the number of prediction instances output by the AI ​​model; and the moving speed of the applicable terminal.

[0173] In some embodiments, the terms "codebook," "codeword," and "precoding matrix" may be used interchangeably. For example, a codebook may be a collection of one or more codewords / precoding matrices.

[0174] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: the number of beams or beam pairs in the first beam set. The measurement values ​​of the first beam set are used as input to the AI ​​model. That is, the number of beams or beam pairs in the first beam set represents the number of measurement values ​​input to the AI ​​model. Different numbers of measurement values ​​input to the AI ​​model result in different performance of the AI ​​model. It is understood that when the terminal sends the number of beams or beam pairs in the first beam set to the network device, it can facilitate the network device to determine whether the AI ​​model meets the performance requirements based on the number of beams or beam pairs in the first beam set to which the AI ​​model is applicable, thereby instructing the terminal to activate or deactivate the AI ​​model. The measurement values ​​of the first beam set are obtained by measuring the beams or beam pairs in the first beam set. Measuring the beams or beam pairs refers to measuring the L1-RSRP and / or L1-SINR of reference signal resources, such as SSB, CSI-RS, SRS, etc.

[0175] In some embodiments, the first set of beams may be set B.

[0176] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: a beam pattern of beams or beam pairs in the first beam set.

[0177] In some embodiments, the beam pattern may indicate the direction in which the reference signal is transmitted and the direction in which the reference signal is not transmitted.

[0178] In some embodiments, the context of the AI ​​function or the context of the AI ​​model includes: the number of beams or beam pairs in the second beam set. The output of the AI ​​model is used to obtain beam information in the second beam set.

[0179] For example, the beams or beam pairs in the first beam set can be measured, and the measured values ​​can be input into the AI ​​model to obtain beam information for the beams or beam pairs in the second beam set. The number of beams or beam pairs in the first beam set and the second beam set, as well as the beam pattern, can both be context for the AI ​​function or AI model.

[0180] In some embodiments, the second set of beams may be set A.

[0181] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: a relationship between a first wave number set and a second beam number set.

[0182] For example, the relationship between the first wave number set and the second beam set may be that the first beam set is a subset of the second beam set. Alternatively, the first beam set is a wide beam and the second beam set is a narrow beam. This disclosure does not list all of these, but is not limited to them.

[0183] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: the content of the AI ​​model input.

[0184] For example, the input of the AI ​​model is the L1-RSRP and / or identifier corresponding to the beam or beam pair in the first beam set. That is, the input of the AI ​​model can be the L1-RSRP corresponding to the beam or beam pair in the first beam set, or the identifier corresponding to the beam or beam pair in the first beam set, or the L1-RSRP and identifier corresponding to the beam or beam pair in the first beam set.

[0185] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: the content output by the AI ​​model.

[0186] For example, the output of the AI ​​model is the L1-RSRP and / or identifier of the beam or beam pair in the second beam set.

[0187] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: AI function or AI model performance monitoring information.

[0188] For example, AI function or AI model performance information includes the performance of the AI ​​function or AI model monitored by the terminal, the performance of the AI ​​function or AI model monitored by the network device, the performance of the AI ​​function or AI model jointly monitored by the terminal and the network device, and performance indicators when the AI ​​function or AI model is monitored. Among them, the performance indicators when the AI ​​model is monitored include the different types of performance mentioned above. When the performance of a certain type of AI function or AI model is poor, it is considered that the AI ​​function or AI model needs to be deactivated or updated.

[0189] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: auxiliary information.

[0190] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: applicable deployment scenarios. For example, the deployment scenario can be an urban macro cell, an urban micro cell, or an indoor location. The deployment scenario can also include different inter-cell distances (ISDs), such as an ISD of 500m or 200m.

[0191] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: a beam codebook of an applicable network device.

[0192] For example, the beam codebook of the applicable network device is a beam codebook used by the applicable network device for transmission.

[0194] For example, the beam codebook of the applicable terminal is the beam codebook used by the applicable terminal for transmission.

[0195] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: distribution information of applicable terminals.

[0197] In some embodiments, the environment of the AI ​​function or the environment characteristics of the AI ​​model include: the number of measurement instances of the AI ​​model input.

[0198] For example, if the AI ​​model is used for time-domain beamforming prediction, the input of the AI ​​model may be multiple measurement instances (time instances), i.e., measurement results at multiple times. The environment of the AI ​​model may include the number of measurement instances input. The number of measurement instances input to the AI ​​model may affect the performance of the AI ​​model.

[0199] In some embodiments, the context of the AI ​​function or the context of the AI ​​model includes: the number of prediction instances output by the AI ​​model.

[0200] For example, if the AI ​​model is used for time-domain beamforming prediction, the output of the AI ​​model may be multiple prediction instances. The environment of the AI ​​model may include the number of prediction instances output. The difference in the number of prediction instances output by the AI ​​model may affect the performance of the AI ​​model.

[0201] In some embodiments, the environment of the AI ​​function or the environment of the AI ​​model includes: the moving speed of the applicable terminal.

[0202] For example, the applicable terminal movement speed indicates the terminal movement speed to which the AI ​​model can be applied. For example, the AI ​​model is applicable to terminals with a movement speed of A. The movement speed can be a speed magnitude or a speed range.

[0203] In some embodiments, the network device may determine to activate or deactivate an AI function or AI model based on the environment of each received AI function or AI model. For example, if the network device needs to perform beam prediction, the AI ​​function or AI model used for beam prediction may be activated. For another example, since the number of beams or beam pairs in the second beam set affects the prediction accuracy of the AI ​​model, the network device may select an AI model to activate or deactivate based on the number of beams or beam pairs in the second beam set of the received AI model.

[0204] In some embodiments, the first information includes capability information, which is used to indicate supported AI functions or AI models.

[0205] For example, the terminal may send the first information when sending the capability information.

[0206] In some embodiments, the first information includes authentication information, which is used to indicate authentication of the AI ​​function and / or AI model.

[0207] For example, the terminal may send the first information when authenticating an AI function and / or an AI model.

[0208] In some embodiments, the AI ​​functionality corresponds to one or more AI models.

[0209] In some embodiments, responsive to performing AI function authentication, the performance of the AI ​​function includes one or more performance values.

[0210] The performance value indicates a numerical value corresponding to the performance.

[0211] For example, the performance of the AI ​​function may be a type of performance. For example, if the performance of the AI ​​function includes beam or beam pair prediction accuracy, the performance value may be one or more of accuracy A, accuracy B, and accuracy C.

[0212] For another example, the performance of an AI function includes multiple types of performance. For example, the performance of an AI function includes beam or beam prediction accuracy, L1-RSRP variability, and predicted delay. The performance values ​​may be accuracy A, variability B, and delay C.

[0213] In some embodiments, in response to performing AI function authentication, the performance of the AI ​​function includes a performance value range.

[0214] In some embodiments, in response to performing AI function authentication, the performance of the AI ​​function includes a performance value, where the performance value is a first performance value among performance values ​​corresponding to multiple AI models, and the first performance value is a maximum value or a minimum value.

[0215] In some embodiments, in response to performing AI function authentication, the performance of the AI ​​function includes multiple performance values, and the multiple performance values ​​are performance values ​​corresponding to multiple AI models.

[0216] In some embodiments, in response to performing AI function authentication, the performance of the AI ​​function includes a performance value range, where the performance value range is a range of performance values ​​corresponding to multiple AI models.

[0217] For example, if an AI function corresponds to one AI model, then the same type of performance of the AI ​​function may include one performance value, i.e., the performance value is the performance value of the AI ​​model corresponding to the AI ​​function. For another example, if the AI ​​function corresponds to multiple AI models, then the same type of performance of the AI ​​function may include one performance value, which may be the maximum value, minimum value, average value, or a specified number of values ​​among the performance values ​​of the multiple AI models corresponding to the AI ​​function. For another example, if the AI ​​function corresponds to multiple AI models, then the same type of performance of the AI ​​function may include multiple performance values, each of which is the performance value of the multiple AI models corresponding to the AI ​​function. For another example, if the AI ​​function corresponds to multiple AI models, then the same type of performance of the AI ​​function may include a performance value range consisting of the performance values ​​corresponding to the multiple AI models of the AI ​​function. The performance value range may be an interval consisting of the maximum and minimum values ​​among the performance values ​​of the multiple AI models corresponding to the AI ​​function. Of course, two performance values ​​may also be selected from multiple performance values ​​as an interval based on a rule, and this disclosure is not limited thereto.

[0218] In some embodiments, the performance includes different types of performance, wherein the AI ​​function or AI model is used for spatial beam prediction, and each type of performance corresponds to a performance value.

[0219] For example, the performance of an AI function or AI model includes multiple types of performance, such as beam or beam pair prediction accuracy, L1-RSRP variability, and predicted L1-RSRP variability. Each type corresponds to a performance value. For example, beam or beam pair prediction accuracy corresponds to a performance value, L1-RSRP variability corresponds to a performance value, and predicted L1-RSRP variability corresponds to a performance value.

[0220] In some embodiments, the performance includes different types of performance. The AI ​​function or AI model is used for time-domain beam prediction, and each type of performance corresponds to multiple performance values. The multiple performance values ​​include a performance value corresponding to each prediction instance.

[0221] For example, the performance of an AI function or AI model includes multiple performance types, such as beam or beam pair prediction accuracy, L1-RSRP variability, and predicted L1-RSRP variability. Each type corresponds to multiple performance values. Taking beam or beam pair prediction accuracy as an example, the prediction accuracy of each beam or beam pair can be included.

[0222] For another example, the AI ​​function is used for time domain beam prediction. If one AI function corresponds to one AI model and there is one prediction instance of the AI ​​model, then each type of performance of the AI ​​function corresponds to one performance value; if one AI function corresponds to multiple AI models and there is one prediction instance of the AI ​​model, then each type of performance of each AI model corresponding to the AI ​​function corresponds to one performance value. The performance corresponding to the AI ​​function can be the maximum value, minimum value, average value or specified value among the performance values ​​of multiple AI models, or a performance value range, or a performance value of the type corresponding to each AI model; if one AI function corresponds to one AI model and there is one AI model If there are multiple prediction instances, the performance corresponding to the AI ​​function includes multiple performance values ​​corresponding to each type of performance of the AI ​​model, and the multiple performance values ​​include the performance value corresponding to each prediction instance; if the AI ​​function corresponds to multiple AI models, and there are multiple prediction instances of the AI ​​model, the AI ​​function includes the performance value of each prediction instance, and the performance value of each prediction instance can be the performance values ​​of the multiple AI models corresponding to the AI ​​function under the prediction instance, or the maximum value, minimum value or average value of the performance values ​​of the multiple AI models corresponding to the AI ​​function under the prediction instance, or the range of performance values ​​composed of the performance values ​​of the multiple AI models corresponding to the AI ​​function under the prediction instance.

[0223] In some embodiments, performance values ​​of one or more types for different prediction instances may be sent independently.

[0224] In some embodiments, the name of the first information is not limited and may be, for example, "performance information", "capability information", etc.

[0226] In some embodiments, the terms "codebook," "codeword," and "precoding matrix" may be used interchangeably. For example, a codebook may be a collection of one or more codewords / precoding matrices.

[0227] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0228] In step S2102 , the network device 102 determines an AI function or an AI model based on the first information.

[0229] In some embodiments, the first information includes the performance of the AI ​​function or AI model supported by the terminal. The network device can determine the AI ​​function or AI model based on the performance requirement and the received performance of each AI function or AI model.

[0230] For example, if the performance requirement is that the beam prediction accuracy of the AI ​​model is greater than A, then based on the performance of each received AI model, the AI ​​model with a beam prediction accuracy greater than A is activated, or the AI ​​model with a beam prediction accuracy less than A is deactivated.

[0231] In some embodiments, the first information includes an identifier of an AI function or an identifier of an AI model supported by the terminal. The network device may receive the identifier of the AI ​​function or the identifier of the AI ​​model corresponding to the performance of each AI function or AI model, and the network device may directly indicate the identifier of the AI ​​function or AI model to activate or deactivate the AI ​​function or model.

[0232] In some embodiments, the first information includes an environment of an AI function or an AI model supported by the terminal. The network device may determine an AI function or AI model that needs to be activated or deactivated based on the performance requirements and the received environment of the AI ​​function or AI model.

[0233] For example, the environment of the AI ​​model includes an AI model for beam prediction. When the network device needs to perform beam prediction, the AI ​​model for beam prediction can be selected and activated based on the received environment of each AI model.

[0305] The present disclosure also provides a communication method as follows:

[0306] The terminal reports the performance of the AI ​​function (functionality) or AI model (model).

[0307] In some embodiments, the terminal reports the performance when performing functionality or model authentication (identification), for example, the terminal informs the network device of the functionality or model supported by the terminal side, and the environment corresponding to the functionality or model, the environment includes the following

[0308] For example, whether the functionality or model is used for beam prediction, CSI compression, CSI prediction, or positioning.

[0309] More specifically, if it is used for beam prediction, is it spatial domain beam prediction or time domain beam prediction?

[0310] Furthermore, in the case of spatial beam prediction, the number and / or pattern of beams (pairs) contained in set B used for model input; the number and / or pattern of beams (pairs) contained in set A corresponding to the model output; the relationship between set B and set A; the model input is L1-RSRP and / or beam ID, and the model output is L1-RSRP and / or beam ID; what auxiliary information is available, what deployment is applicable, the beam codebook applicable to the base station (gNB), and the beam codebook applicable to the terminal (UE); applicable UE distribution information; and applicable UE mobility speed.

[0311] In some embodiments, a beam refers to a beam, and a beam measurement refers to measuring the L1-RSRP and / or L1-SINR of reference signals including SSB, CSI-RS, and SRS; a beam indication refers to an indication of a transmission configuration indication (TCI) state, where the TCI state includes at least one quasi co-location (QCL) type, including QCL types A, B, C, and D, where type D is reception parameter information, commonly known as a beam. Types A, B, and C include at least one of parameters related to Doppler shift, Doppler spread, average delay, and delay spread. For an uplink beam, it refers to spatial relation information, a spatial filter parameter, or an uplink TCI state.

[0312] In some embodiments, a functionality ID or a model ID may also be reported.

[0313] In some embodiments, the terminal reports the performance based on a UE capability mechanism, for example, the terminal reports that it can support the functionality or model and reports the corresponding performance at the same time.

[0314] In some embodiments, the above also includes the above environment.

[0315] In some embodiments, functionality identification is distinguished from model identification.

[0316] In some embodiments, functionality identification simply informs the network of support for a particular functionality. The terminal may not need to inform the network whether it supports one or multiple models within that functionality. Therefore, when the network instructs the terminal to activate a particular functionality, the terminal can independently determine which model to activate within that functionality. Furthermore, the terminal does not need to inform the network when switching between different models within that functionality.

[0317] In some embodiments, model identification is to inform the network that the terminal supports a certain model. The model may correspond to one or more functionalities. The network device may instruct the terminal to activate or deactivate the model.

[0318] In some embodiments, the performance may include at least one of the following, taking the beam prediction model as an example.

[0319] 1) Beam prediction accuracy: beams (pairs) with a beam prediction accuracy of top 1 / K.

[0320] In some embodiments, a correct prediction means that the predicted strongest beam (pair) ID includes the measured strongest beam (pair) ID, or the predicted strongest beam (pair) ID is included in the N strongest measured beam (pair) IDs. The downlink transmit beam ID can be equivalent to a reference signal resource ID, such as an SSB ID, a CSI-RS ID, or an SRS ID. The downlink receive beam ID is the terminal's Rx beam ID. The beam pair ID is the ID corresponding to the combination of the downlink transmit beam and the downlink receive beam.

[0321] In some embodiments, the strongest means that the L1-RSRP or L1-SINR is the strongest.

[0322] In some embodiments, this indicator may be the accuracy of the beam information output based on multiple derivations of the model, for example, it may be a ratio.

[0323] 2) Beam prediction accuracy within 1 dB: The accuracy of the predicted best beam (pair) when the measured L1-RSRP is within 1 dB of the measured L1-RSRP of the best beam.

[0324] In some embodiments, this indicator may be the accuracy of the beam information output based on multiple derivations of the model, for example, a ratio.

[0325] 3) L1-RSRP Difference: The difference between the measured L1-RSRP of the predicted best beam (pair) and the measured L1-RSRP of the best beam, for example, the average value is X dB, or the value at the 5% percentile of the cumulative distribution function is Y dB.

[0326] In some embodiments, it may also be a ratio of the L1-RSRP difference being lower than a threshold value, or a ratio of the L1-RSRP difference being higher than a threshold value.
