The subjects shown in FIG1 are examples, and the communication system may include all or part of the subjects in FIG1 , or may include other subjects other than FIG1 , and the number and form of the subjects are arbitrary, and the subjects may be physical or virtual, and the connection relationship between the subjects is an example, and the subjects may be connected or disconnected, and the connection may be in any manner, and may be a direct connection or an indirect connection, and may be a wired connection or a wireless connection.

[0105] The embodiments of the present disclosure may 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) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application.

[0106] In the disclosed embodiment, 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 the coverage range.

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

[0108] In the related art, it is assumed that the reference signal resource set configured by the network device includes X reference signal resources, and each reference signal resource corresponds to a different transmitting beam of the network device. Then for each reference signal resource, the terminal needs to use all receiving beams to measure the reference signal. Thereby obtaining the beam measurement qualities corresponding to all receiving beams respectively. 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. Among them, G represents the number of transmitting beams of the network device, and H represents the number of receiving beams of the terminal.

[0109] In some embodiments, an implementation process of beam prediction by an AI model and / or AI function is provided, wherein the 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 may be referred to as a beam prediction model. Of course, it may also be referred to as a beam prediction AI model, a prediction AI model, a prediction beam model, etc. This disclosure does not limit the names of such AI models.

[0111] In some implementations, when the beam prediction model is a spatial prediction, the terminal measures the L1-RSRP of set B and inputs it 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] Among them, 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 the reference signal resources, for example, set B contains 8 reference signal resources out 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 direction of 120 degrees). And set B contains another Y reference signal resources, for example, Y=8. And these Y reference signal resources also cover a direction of 120 degrees, 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 one reference signal resource in set B is QCL Type D.

[0115] It can be understood that in the examples of the first and second relationships above, only the case of the transmit beam is described. When considering a beam pair including a transmit beam and a receive beam, the receive beam of the terminal must also be considered. For example, if there are 32 transmit beams and 4 receive beams, then set A is 32*4 beam pairs, and set B can be 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. The L1-RSRP corresponding to the reference signal resource of set A can be output, or one or more reference signal resource IDs of the strongest of the 32 reference signal resources in set A can be output.

[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 (such as 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 each embodiment of the present disclosure, the "terminal side model" and the "AI model deployed on the terminal" can be used interchangeably. The "network device side model" and the "AI model deployed on the network device" can be used interchangeably.

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

[0120] For beam measurement using the method in the related art, the reference signal at the future time also needs to be sent by the base station. The terminal measures the reference signal at the future time and reports the measured beam information to the network device. That is, the terminal needs to measure the beam information of all beams and / or beam pairs in set A and report it 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 part of the G*H beam pairs. For example, measure 1 / 8, 1 / 4 of G*H beam pairs, etc. Then, the measured beam measurement quality of these beam pairs 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, the beam quality or beam identification of the beam pair may not be considered, and only the beam quality or beam identification of the downlink transmit beam may be considered. 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 is clear that AI models have a certain life cycle or a certain scope of application. For example, some AI models are suitable for suburbs, some AI models are suitable for urban areas, and some AI models are suitable for indoor and other specific environments. For another example, some AI models are suitable for rush hour in the morning and evening, and some AI models are suitable for specific time periods such as when there are few people at work. For another example, some AI models may be suitable for specific times and specific environments, such as AI models are suitable for the road when there are many people at work. Therefore, it is necessary to monitor the performance of the AI ​​model in real time. When the performance of the AI ​​model does not meet the corresponding requirements, it is necessary to update and switch the AI ​​model in a timely manner.

[0124] In some embodiments, different AI models also have different corresponding performances. 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 is different, 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] In some embodiments, the AI ​​function corresponds to one or more AI models. If the AI ​​function corresponds to multiple AI models, the network device cannot control the AI ​​model when managing the life cycle of the AI ​​function. That is, the network device can only manage the AI ​​function on the terminal side, such as configuring or activating or deactivating or switching the AI ​​function, and the network cannot control which AI model the terminal side specifically configures or activates or deactivates or switches the AI ​​function to. In this case, if the performance of each AI model corresponding to the AI ​​function on the terminal side is different, the network device cannot control the terminal to select the correct AI model.

[0132] In some embodiments, the network device may determine the first information based on the performance and performance requirements of each received AI model. The first information is used to instruct the terminal to select an AI model that meets the performance requirements.

[0133] For example, the network device can determine the AI ​​model that meets the performance requirements based on the performance of each received AI model, and send an AI model identifier that identifies the AI ​​model to the terminal to instruct the terminal to select the AI ​​model that meets the performance requirements.

[0134] In some embodiments, the name of the performance of each AI model is not limited, and can be, for example, "performance information", "capability information", etc.

[0135] Step S2102 , the network device 102 sends first information to the terminal 101 .

[0136] In some embodiments, the terminal 101 receives first information sent by the network device 102 .

[0137] In some embodiments, the first information is used to instruct the terminal to select an AI model that meets performance requirements.

[0138] In some embodiments, the first information includes at least one of the following:

[0139] AI function identification;

[0140] AI model identification;

[0141] Performance requirements.

[0142] In some embodiments, the first information may include an AI function identifier, wherein the AI ​​function identified by the AI ​​function identifier is an AI function managed by the network device. Management may include configuration, activation, deactivation, switching, and falling back to a non-AI mode.

[0143] In some embodiments, one AI function corresponds to one or more AI models. When one AI function corresponds to one AI model, the first information includes an AI function identifier, and the AI ​​model corresponding to the AI ​​function identified by the AI ​​function identifier can be managed. When one AI function corresponds to multiple AI models, the first information includes an AI function identifier, and an AI model can be selected from the multiple AI models corresponding to the AI ​​function identified by the AI ​​function identifier for management.

[0144] In some embodiments, the first information may include an AI model identifier.

[0145] In some embodiments, the terminal may send the performance of each AI model to the network device. The first information includes an AI model identifier, and the AI ​​model identified by the AI ​​model identifier may be managed according to the AI ​​model identifier.

[0146] In some embodiments, the first information may include performance requirements.

[0147] In some embodiments, different AI models have different performances, and the first information includes performance requirements, and an AI model that meets the performance requirements can be selected according to the performance requirements. For example, the performance requirement included in the first information is that the prediction accuracy of beam prediction is greater than A, and the terminal manages the AI ​​model with a prediction accuracy greater than A.

[0148] In some embodiments, the first information includes an AI function identifier and performance requirements.

[0149] For example, if the lifecycle management is based on the lifecycle management of the AI ​​function, the first information may include the AI ​​function identifier and the performance requirement. The terminal may select the AI ​​function identified by the AI ​​function identifier according to the AI ​​function identifier, and select the AI ​​model that meets the performance requirement corresponding to the AI ​​function for management according to the performance requirement.

[0150] In some embodiments, the first information includes an AI model identification and performance requirements.

[0151] For example, if the lifecycle management is based on the lifecycle management of the AI ​​model, the first information may include the AI ​​model identifier and the performance requirement. The AI ​​model identifier may be one or more. When there are multiple AI model identifiers, an AI model that meets the performance requirement may be selected for management according to the performance requirement.

[0152] In some embodiments, the performance requirements include different types of performance requirements.

[0153] This disclosure will use the AI ​​function or AI model for beam prediction as an example to illustrate the performance requirements, but the AI ​​function or AI model is not limited to beam prediction. For example, it can also be used for CSI compression, CSI prediction, positioning, etc. This disclosure does not list them one by one.

[0154] Among them, different types of performance requirements can also be called performance requirements of different dimensions. The performance requirements include 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 being 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 being 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 measured L1-RSRP of the best predicted beam or beam pair. The method comprises the following steps: a first step of predicting the L1-RSRP of a wireless communication system and a second step of predicting the L1-RSRP of a wireless communication system; a second step of predicting the L1-RSRP of a wireless communication system; a third step of predicting the L1-RSRP of a wireless communication system; a fourth step of predicting the L1-RSRP of a wireless communication system; and a fourth step of predicting the L1-RSRP of a wireless communication system. The method comprises the following steps: a first step of predicting the L1-RSRP of a wireless communication system and a second step of predicting the L1-RSRP of a wireless communication system. The method comprises the following steps: a first step of predicting the L1-RSRP of a wireless communication system and a second step of predicting the L1-RSRP of a wireless communication system. The method comprises the following steps:

[0155] In some embodiments, terms such as "uplink", "uplink", "physical uplink" can be interchangeable, and terms such as "downlink", "downlink", "physical downlink" can be interchangeable, and terms such as "side", "sidelink", "side communication", "sidelink communication", "direct connection", "direct link", "direct communication", "direct link communication" can be interchangeable.

[0156] 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.

[0157] In some embodiments, the performance requirements include: beam or beam pair prediction accuracy.

[0158] For example, when using the AI ​​model for beam prediction, if the predicted best K1 beams include the measured best beam, the prediction is accurate. Or if the predicted best 1 beam is among the measured best K2 beams, the prediction is accurate. Then, if the AI ​​model is used to perform M beam predictions, and N of the predictions are correct, the prediction accuracy is N / M. K1 and K2 are positive integers, such as 1, 2, 3, 4, 5, etc.

[0159] In some embodiments, the downlink transmission beam ID may be equivalent to the reference signal resource ID, for example, it may be a synchronization signal block (SSB) ID, a sounding reference signal (SRS) ID, a channel state information reference signal (CSI-RS) ID, etc. The downlink reception beam ID may be a reception beam ID of the terminal. The beam pair ID may be an ID corresponding to a combination of a downlink transmission beam and a downlink reception beam.

[0160] In some embodiments, terms such as "synchronization signal (SS)", "synchronization signal block (SSB)", "reference signal (RS)", "pilot", and "pilot signal" can be used interchangeably.

[0161] In some embodiments, the best beam may be the beam with the strongest L1-RSRP or L1-SINR.

[0162] In some embodiments, the performance requirement includes: beam or beam pair prediction accuracy with 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.

[0163] For example, when using the AI ​​model for beam prediction, if the difference between the measured L1-RSRP of the predicted best beam and the measured L1-RSRP of the measured best beam is less than the first threshold, it means that the prediction is accurate. Then, the AI ​​model is used to perform P beam predictions, where the difference between the measured L1-RSRP of the predicted best beam and the measured L1-RSRP of the measured best beam is less than the first threshold, then the prediction accuracy of the beam or beam pair whose L1-RSRP difference is within the first threshold is Q / P. Among them, the best predicted beam represents the best beam predicted by the AI ​​model. The measured L1-RSRP represents the L1-RSRP obtained by measuring the beam. That is, the measured L1-RSRP of the predicted best beam represents the best beam predicted by the AI ​​model, and the L1-RSRP is measured for the best beam. The measured best beam represents the best beam obtained by actual measurement. For example, the actual measurement may be to measure 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 L1-RSRP of the best beam means obtaining the best beam through actual measurement, and measuring the best beam to obtain L1-RSRP.

[0164] In some embodiments, the first threshold may be, for example, 1 dB, and the prediction accuracy of the beam or beam pair whose L1-RSRP difference is within the first threshold may be the prediction accuracy of the beam or beam pair whose 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 beam or beam pair.

[0165] In some embodiments, the performance requirement includes: 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 before measurement.

[0166] In some embodiments, the L1-RSRP difference may be the average value of the L1-RSRP difference. For example, the AI ​​model is used to perform one or more predictions to obtain A best prediction beams, and the A best prediction beams are measured respectively to obtain the measured L1-RSRP of the A best prediction beams. The difference between the predicted L1-RSRP of the A best prediction beams and the measured L1-RSRP of the measured best beam is calculated respectively, and the average value is taken, which is the average value of the L1-RSRP difference, that is, the L1-RSRP difference. Among them, the A best beams may be the A best beams obtained by using the AI ​​model to perform a prediction once, or the A best beams obtained by using the AI ​​model to perform multiple predictions.

[0167] In some embodiments, the L1-RSRP difference may be a cumulative distribution function of the L1-RSRP difference. For example, the value of the cumulative distribution function of the L1-RSRP difference at a certain fixed percentage point is the L1-RSRP difference.

[0168] In some embodiments, the L1-RSRP difference may be a value of a cumulative distribution function at 5%, for example, YdB.

[0169] In some embodiments, the L1-RSRP difference may be a ratio of the L1-RSRP difference being less than or equal to the second threshold. For example, if model AI is used to perform A predictions, and there are B predictions where the L1-RSRP difference is less than or equal to the second threshold, then the L1-RSRP difference is B / A.

[0170] In some embodiments, the L1-RSRP difference may be a ratio of the L1-RSRP difference greater than a third threshold. For example, if the AI ​​model is used to perform C predictions, and there are D L1-RSRP differences greater than the third threshold, then the L1-RSRP difference is D / C.

[0171] Wherein, greater than the third threshold value may also mean greater than or equal to the third threshold value, which is not limited in the present disclosure. The first threshold value, the second threshold value, and the third threshold value in the present disclosure may be set according to actual conditions, and the first threshold value, the second threshold value, and the third threshold value may be the same or different.

[0172] In some embodiments, the performance requirement includes: a predicted L1-RSRP difference. The predicted L1-RSRP difference is a difference between a predicted L1-RSRP of the best predicted beam or beam pair and a measured L1-RSRP of the best predicted beam or beam pair.

[0173] The predicted L1-RSRP indicates the predicted L1-RSRP obtained by predicting the L1-RSRP of the beam through the AI ​​model. That is, the predicted L1-RSRP of the best predicted beam or beam pair indicates the best predicted beam predicted through the AI ​​model, and then the L1-RSRP of the best predicted beam predicted through the AI ​​model.

[0174] In some embodiments, the predicted L1-RSRP difference may be an average value of the predicted L1-RSRP differences.

[0175] In some embodiments, the predicted L1-RSRP difference may be a cumulative distribution function of the difference in predicted L1-RSRP.

[0176] In some embodiments, the predicted L1-RSRP difference may be a ratio of the predicted L1-RSRP difference being less than or equal to a fourth threshold.

[0177] In some embodiments, the predicted L1-RSRP difference may be a ratio of the predicted L1-RSRP difference being greater than a fifth threshold.

[0178] The difference in predicted L1-RSRP 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.

[0179] The best predicted beam, predicted best beam, and predicted best beam in the present disclosure have the same meaning and can be used interchangeably.

[0180] In some embodiments, the performance requirements include: terminal throughput. For example, the SINR of the predicted best beam or beam pair and the measured best beam or beam pair may be determined, and the capacity corresponding to each beam or beam pair may be calculated based on the Shannon capacity. The difference between the capacities corresponding to the two beams or beam pairs may be used as the average UE throughput difference.

[0181] 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%.

[0182] In some embodiments, the performance requirements include: reference signal overhead. The reference signal overhead is how much reference signal resources the AI ​​model requires.

[0183] 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.

[0184] In some embodiments, the performance requirements include: 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, and the uplink control information overhead is the signaling overhead of sending the measurement results of set B.

[0185] In some embodiments, the performance requirements include: predicted delay. For example, the unit of the predicted delay may be milliseconds (ms), which means that the multiple beam information measured at time A is input into the AI ​​model, and after the prediction of the AI ​​model, the best beam is obtained at time B, and the predicted delay is the difference between time A and time B. For example, the smaller the predicted delay, the better the performance of the AI ​​model.

[0186] In some embodiments, the first information includes an environment of the AI ​​model.

[0187] In some embodiments, the environment may include an environment (condition) or an additional environment (additional condition), and the environment may represent an environment or condition, etc., to which the AI ​​model is applicable, or represent a feature of the AI ​​model.

[0188] For example, the AI ​​model environment is that the 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 ​​model is used for spatial domain beam prediction, or for time domain beam prediction.

[0189] The present disclosure takes the AI ​​model for spatial beam prediction as an example. The environment of the AI ​​model also 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 beam or beam pair 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 the beam information in the second beam set; the beam pattern of the beam or beam pair 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 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 by the AI ​​model; the number of prediction instances output by the AI ​​model; the moving speed of the applicable terminal.

[0190] In some embodiments, the terms "codebook", "codeword", "precoding matrix" and the like can be interchangeable. For example, a codebook can be a collection of one or more codewords / precoding matrices.

[0191] In some embodiments, the environment of the AI ​​model includes: 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. 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. The number of measurement values ​​input to the AI ​​model is different, and the performance of the AI ​​model is different. It can be understood that the terminal sends the number of beams or beam pairs in the first beam set to the network device, which 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. Among them, the measurement value of the first beam set is obtained by measuring the beams or beam pairs in the first beam set. Measuring a beam or beam pair refers to measuring its L1-RSRP and / or L1-SINR for reference signal resources, such as SSB, CSI-RS, SRS, etc.

[0192] In some embodiments, the first set of beams may be set B.

[0193] 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.

[0194] In some embodiments, the beam pattern may indicate a direction in which a reference signal is transmitted and a direction in which a reference signal is not transmitted.

[0195] 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.

[0196] For example, the beams or beam pairs in the first beam set may be measured first, and the measured values ​​may be input into the AI ​​model to obtain beam information of 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 and the beam pattern may be the environment of the AI ​​function or AI model.

[0315] The present disclosure also provides a communication method as follows:

[0316] In some embodiments, the terminal receives first information, where the first information is used to configure or activate or indicate an AI function or an AI model, and the first information includes at least one of the following:

[0317] 1) AI functional identity (functionality ID).

[0318] In some embodiments, each AI functionality corresponds to a functionality ID, such as whether the functionality is used for beam prediction, CSI compression, CSI prediction, or positioning.

[0319] More specifically, if it is used for beam prediction, it is spatial domain beam prediction or time domain beam prediction.

[0320] Furthermore, if it is 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; applicable UE moving speed.

[0321] In some embodiments, beam refers to beam, beam measurement refers to measuring L1-RSRP and / or L1-SINR for reference signals including SSB, CSI-RS, and SRS; beam indication refers to an indication of a transmission configuration indication (TCI) state, wherein the TCI state includes at least one quasi co-location (QCL) type, QCL types A, B, C, and D, wherein type D is reception parameter information, commonly known as beam. Type 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 or a spatial filter parameter or an uplink TCI state.

[0322] 2) AI model identification (model ID).

[0323] In some embodiments, each model corresponds to a model ID

[0324] 3) Performance requirements.

[0325] In some embodiments, the performance in the performance requirement may include at least one of the following values ​​(all taking the beam prediction model as an example):

[0326] 1) Beam prediction accuracy: beam prediction accuracy of top 1 / K beam(pair).

[0327] In some embodiments, 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 the reference signal resource ID, such as SSB ID or CSI-RS ID or SRS ID. The downlink receive beam ID is the Rx beam ID of the terminal. The beam pair ID is the ID corresponding to the combination of the downlink transmit beam and the downlink receive beam.

[0328] In some embodiments, the strongest means that the L1-RSRP or L1-SINR is the strongest.

[0329] In some embodiments, this indicator may be the accuracy of the output beam information based on multiple derivations of the model, for example, it may be a ratio.

[0330] 2) Beam prediction accuracy within 1 dB: The accuracy when the measured L1-RSRP of the predicted best beam (pair) is within 1 dB of the measured L1-RSRP of the measured best beam.

[0331] In some embodiments, this indicator may be the accuracy of the output beam information based on multiple derivations of the model, for example, it may be a ratio.

[0332] 3) L1-RSRP difference: The difference between the measured L1-RSRP of the predicted best beam (pair) and the measured L1-RSRP of the measured best beam, such as the average value of X dB, or the value at the 5% percentile of the cumulative distribution function of Y dB.

[0333] 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.

[0334] 4) Predicted L1-RSRP difference: The difference between the measured L1-RSRP of the predicted best beam(pair) and the predicted L1-RSRP of the best beam(pair), e.g., the average is X dB, or the value at the 5% percentile of the cumulative distribution function is Y dB.

[0335] In some embodiments, it may also be a ratio of the Predicted L1-RSRP difference being lower than a threshold value, or a ratio of the Predicted L1-RSRP difference being higher than a threshold value.

[0336] 5) Average UE throughput, or the UE throughput at 5% of the cumulative distribution function.

[0337] In some embodiments, based on the predicted strongest beam (pair) and the measured strongest beam (pair), SINRs corresponding to the two beams (pairs) are obtained, and capacity is calculated based on Shannon capacity, and the difference in capacity is the indicator.

[0338] 6) Reference signal overhead.

[0339] That is, how much reference signal resources the AI ​​model needs. The main influencing factors include the size of set B corresponding to the model input and the number of historical measurement times during time domain prediction.

[0340] 7) Uplink control information overhead.

[0341] In some embodiments, if it is a network deployment (NW-side) model, then the measurement results of set B need to be reported to the network, that is, the signaling overhead of this reporting.

[0342] 8) Predicted delay. Milliseconds (ms)

[0343] In some embodiments, for AI functionality based model management, performance requirements are indicated during AI functionality configuration / activation.

[0344] 1) Can indicate a performance requirement.

[0345] In some embodiments, since there may be multiple models on the terminal side to implement the functionality, and after the network side gives this performance requirement, the terminal cannot select a model at random, but needs to select a model that meets the requirement.

[0346] 2) Time domain beam prediction

[0347] In some embodiments, if the model is required to predict multiple time instances, the performance requirements of multiple time instances can be indicated independently, that is, each time instance corresponds to one or a set of performance requirements.

[0348] In some embodiments, for model based model management, if the terminal has reported the performance of each model, the model ID can be directly indicated without additional indication requirement.

[0349] 1) If the terminal has not reported the performance of each model, it can indicate one or more model IDs and the performance requirement. That is, it instructs the terminal to activate one of the models that meets the requirement among multiple model IDs.

[0350] 2) The time domain beam prediction is the same as above, that is, if the model predicts the beam information of multiple time instances, then the performance requirement corresponding to each time instance needs to be given independently.

[0351] In some embodiments, the first information may be carried via RRC, MAC CE and / or DCI.

[0352] The embodiments of the present disclosure also propose a device for implementing any of the above methods, for example, a device is proposed, the above device includes a unit or module for implementing each step performed by the terminal in any of the above methods.
