The CSI generation partial model on the terminal side and the CSI recovery partial model on the network device side can be bilateral artificial intelligence (AI)/machine learning (ML) models. Figure 1b is a schematic diagram of the bilateral AI/ML model to realize CSI compression feedback and recovery. The UE side compresses the downlink channel information H through the CSI generation partial model and quantizes it into a binary bit stream and sends it to the network side device (such as gNB). The network side device recovers H' which is similar to the original downlink information through the CSI recovery partial model.

在一些实施例中，UE或gNB选择AI模型可以根据以下计算的性能准则或方法：In some embodiments, the UE or gNB may select an AI model based on the following performance criteria or methods:

可选方案1：中间KPI如余弦相似度的平方。Option 1: Intermediate KPI such as the square of cosine similarity.

对于可选方案1方案，UE可以上报目标输入CSI(即input-CSI-NW)，或者NW发送目标输出CSI(即output-CSI-UE)分别实现NW侧或UE侧的计算中间KPI。For Option 1, the UE may report the target input CSI (i.e., input-CSI-NW), or the NW may send the target output CSI (i.e., output-CSI-UE) to respectively implement the calculation of the intermediate KPI on the NW side or the UE side.

可选方案2：最终的KPI，如吞吐量、误块率(Block Error Rate，BLER)、假定的BLER或非确认(NACK)/确认(ACK)。Option 2: Final KPIs such as throughput, Block Error Rate (BLER), assumed BLER, or non-acknowledgement (NACK)/acknowledgement (ACK).

可选方案3：基于传统的CSI反馈上报作为选择模型的参考。Option 3: Use traditional CSI feedback reporting as a reference for selecting a model.

传统的CSI反馈上报包含了基于Type I或Type II码本进行CSI测量和上报，码本类型或码本参数是由NW配置给UE。Traditional CSI feedback reporting includes CSI measurement and reporting based on Type I or Type II codebooks. The codebook type or codebook parameters are configured by the NW to the UE.

可选方案4：AI/ML网络模型的输入或输出数据分布，如训练数据和观测数据之间的数据飘移变化。Option 4: Input or output data distribution of AI/ML network models, such as data drift changes between training data and observation data.

假设UE已部署了M≥1个CSI生成部分模型，gNB部署了M≥1个CSI恢复部分模型。或者在UE或gNB部署了M个CSI生成部分模型和CSI恢复部分模型对。为了获取更好的系统性能，需要保证UE侧所用的CSI生成部分模型与gNB侧所用的CSI恢复部分模型的匹配关系，即保证二者是兼容的。Assume that the UE has deployed M≥1 CSI generation partial models and the gNB has deployed M≥1 CSI recovery partial models. Or M CSI generation partial models and CSI recovery partial model pairs are deployed on the UE or gNB. In order to obtain better system performance, it is necessary to ensure that the CSI generation partial model used on the UE side matches the CSI recovery partial model used on the gNB side, that is, to ensure that the two are compatible.

对于不同的场景、不同的配置等情况下，UE侧或NW侧部署了M>1个部分模型或者部分模型和CSI恢复部分模型对时，在UE或gNB侧如何选择一个与对端所用模型相匹配或兼容的部分模型，是需要待解决的问题。另外，随着在UE侧的部分模型执行，UE的电量等硬件条件的局限性也会限制在UE侧可用的模型个数，如何通知gNB从可用的模型中选择1个相匹配或兼容的模型来匹配终端的状态，同样是需要待解决的问题。 For different scenarios, different configurations, etc., when M>1 partial models or partial models and CSI recovery partial models are deployed on the UE side or NW side, how to select a partial model that matches or is compatible with the model used by the other end on the UE or gNB side is a problem that needs to be solved. In addition, with the execution of partial models on the UE side, the limitations of hardware conditions such as UE power will also limit the number of models available on the UE side. How to notify the gNB to select a matching or compatible model from the available models to match the terminal status is also a problem that needs to be solved.

以下结合上述任意实施例提供些具体示例：The following provides some specific examples in combination with any of the above embodiments:

假设在UE或网络部署了M>1个能用于CSI压缩的模型，UE通过能力上报指示可支持的用于CSI压缩的AI模型。下述中所述的AI模型可以UE(如终端)侧或NW(如网络设备)侧的部分模型，也可以是一个UE侧和NW侧的部分模型对。下述给出了选择模型的实施方式：Assuming that M>1 models that can be used for CSI compression are deployed in the UE or the network, the UE indicates the supported AI models for CSI compression through capability reporting. The AI model described below can be a partial model on the UE (such as a terminal) side or the NW (such as a network device) side, or a partial model pair on the UE side and the NW side. The following gives an implementation method for selecting a model:

实施方式1：UE侧选择模型。 Implementation method 1: UE side selects the model.

方案1：(UE在初始接入网络后，首次进行基于M个模型进行选择)：Solution 1: (After the UE initially accesses the network, it makes the first selection based on M models):

步骤1：UE侧根据网络配置的参数信息或其它辅助信息从M个模型中确定1≤N≤M个模型。如根据网络配置的场景信息确定该场景下的N个模型。确定N个模型的方式：Step 1: The UE side determines 1≤N≤M models from M models according to the parameter information or other auxiliary information configured by the network. For example, the N models in the scenario are determined according to the scenario information configured by the network. The method for determining the N models is as follows:

方式1：根据NW配置参数或辅助信息,UE和NW均可确定N个模型，如确定某一户外(outdoor)场景下只有这N个模型。Method 1: According to NW configuration parameters or auxiliary information, both the UE and the NW can determine N models, such as determining that there are only these N models in a certain outdoor scene.

方式2：UE通过上报或一个大小为M的bitmap指示UE支持或可用的N个模型。Method 2: UE reports Or a bitmap of size M indicates N models supported or available by the UE.

步骤2：UE再从N个模型中选择1个模型，并把所选的模型指示信息发送给NW，或者UE直接把所选模型的ID发送给。指示所选的模型开销为或者可选地，NW向UE发送这N个模型中NW part模型的输出信息。Step 2: UE selects one model from N models and sends the selected model indication information to NW, or UE directly sends the ID of the selected model to NW. The overhead of indicating the selected model is or Optionally, the NW sends output information of the NW part model in the N models to the UE.

方案2：(在UE运行模型一段时间后，因UE电量等硬件条件限制，复杂度高的模型不再支持相应地所有N个模型，N是方案1中步骤1所述确定的N个模型。)：Solution 2: (After the UE runs the model for a period of time, due to hardware conditions such as UE power, the model with high complexity no longer supports all N models accordingly, where N is the N models determined in step 1 of solution 1.)

Alt1-1：UE主动向NW发送信令通知可用的模型个数K和从K个模型中选择1个模型的指示信息。或者，UE根据接收的1个或N个NW part模型输出的信息确定从K个模型中选择1个模型。UE可通过或者大小为N的bitmap指示候选可用的K个模型，其中用于确定K的值，是用于指示从N中选择了哪K个模型，然后UE再通过指示从K个模型中选择的其中1个model，或者UE直接把所选模型的ID指示给NW。Alt1-1: The UE actively sends a signaling to the NW to notify the number of available models K and the indication information of selecting one model from the K models. Alternatively, the UE determines to select one model from the K models based on the information output by one or N NW part models received. The UE can Or a bitmap of size N indicates K candidate models, where To determine the value of K, It is used to indicate which K models are selected from N, and then the UE passes Indicate one model selected from K models, or the UE directly indicates the ID of the selected model to the NW.

可选地，UE向NW发送信令指示当前所用的模型已不可用，让NW对当前的模型去激活，执行fallback操作或者NW再重新指示UE选择模型。Optionally, the UE sends a signaling to the NW to indicate that the currently used model is no longer available, so that the NW deactivates the current model and performs a fallback operation, or the NW re-instructs the UE to select a model.

Alt1-2：UE向NW发送UE的状态信息，让NW确定是否允许进行模型选择，并向UE发送模型选择的指示信息。则UE根据NW发送的指示信息确定是否从K个模型中再选择一个模型。若允许UE再选择模型，UE基于Alt1-1方法从K个模型中选择的其中1个model。若接收的信令为指示UE进行fallback操作，则UE不需要再执行model选择。Alt1-2: The UE sends the UE status information to the NW, allowing the NW to determine whether to allow model selection, and sends the model selection indication information to the UE. The UE then determines whether to select another model from the K models based on the indication information sent by the NW. If the UE is allowed to select a model again, the UE selects one of the K models based on the Alt1-1 method. If the received signaling indicates that the UE performs a fallback operation, the UE does not need to perform model selection again.

实施方式2：NW侧选择模型。Implementation method 2: NW side selection model.

实施方式2-1：单步执行模型的选择。Implementation 2-1: Selection of single-step execution model.

NW直接根据接收的UE发送的第一信息从M个模型中选择1个模型。其中所述UE发送的第一信息可以为UE侧根据下行导频确定的信道信息的特征向量、采用M个UE侧的部分模型分别对特征向量进行压缩后的CSI和模型ID相关信息。UE发送的第一信息是UE再接收到NW发送的NW侧选择模型的信令后，向NW发送M个模型的信息。发送第一信息中包含的各内容可以通过一次信令发送，也可通过多次信令发送。一次信令发送时，各模型对应的压缩信息由model ID区分，或按照预定义规则分别发送各模型的压缩信息。NW directly selects one model from M models based on the first information received from the UE. The first information sent by the UE can be the characteristic vector of the channel information determined by the UE side based on the downlink pilot, the CSI and model ID related information after the characteristic vector is compressed using some models of M UE sides. The first information sent by the UE is the information of M models sent to the NW after the UE receives the signaling sent by the NW to select the model on the NW side. The contents contained in the first information can be sent through one signaling or multiple signaling. When the signaling is sent once, the compressed information corresponding to each model is distinguished by the model ID, or the compressed information of each model is sent separately according to predefined rules.

实施方式2-2：分两步选择模型。Implementation method 2-2: Select the model in two steps.

步骤1：NW通过第一信令向UE发送N个候选模型的指示信息，NW可通过一个大小为M的bitmap指示或者指示。Step 1: NW sends indication information of N candidate models to UE through the first signaling. NW can indicate or instruct.

步骤2：NW接收UE发送的模型选择指示信息确定是否选择模型，若UE允许NW选择模型，NW根据接收的UE发送信息从N<M个模型中选择1个模型。若UE不允许NW选择模型，如当前配置下没有可用的模型，NW不做模型选择。Step 2: NW receives the model selection indication information sent by UE to determine whether to select a model. If UE allows NW to select a model, NW selects one model from N<M models according to the received information sent by UE. If UE does not allow NW to select a model, such as there is no available model under the current configuration, NW does not select a model.

步骤3：NW向UE发送第二信令指示NW所选的模型，或者指示UE执行fall back操作。第二信令可以包含为NW所选模型ID信息，或者指示的NW所选模型。Step 3: The NW sends a second signaling to the UE to indicate the model selected by the NW, or to instruct the UE to perform a fall back operation. The second signaling may include the model ID information selected by the NW, or Indicates the NW selected model.

实施方式3：NW和UE侧联合选择模型。Implementation method 3: NW and UE side joint selection model.

步骤1：UE接收网络配置参数信息或其它辅助信息和进行模型选择的指示信息，并根据接收网络配置的参数信息或其它辅助信息从M(N)个模型中确定1≤N(K)≤M(N)个可用模型。如根据网络配置的场景信息确定该场景下的N(K)个模型，或者根据UE的运行状态确定可用的K个模型。UE通过Alt1的方法把确定的N或K个模型指示给NW。Step 1: The UE receives network configuration parameter information or other auxiliary information and indication information for model selection, and determines 1≤N(K)≤M(N) available models from M(N) models according to the received network configuration parameter information or other auxiliary information. For example, the N(K) models in the scenario are determined according to the scenario information of the network configuration, or the available K models are determined according to the operating status of the UE. The UE indicates the determined N or K models to the NW through the method of Alt1.

步骤2：NW接收UE选择N或K个模型的指示信息，以及接收的UE发送信息从N或K个模型中选择1个模型。NW把所选的模型信息或选择模型结果的指示信息发送给UE，所述指示信息与Alt2-2中step3所述类似，即为或指示所选的模型或把所选模型ID发送给UE，或者指示信息为NW没有选择到满足要求条件的模型，指示UE执行其它操作，如采用传统non-AI的CSI反馈。Step 2: NW receives the indication information of UE selecting N or K models, and receives the information sent by UE to select one model from N or K models. NW sends the selected model information or the indication information of the selected model result to UE, and the indication information is similar to that described in step 3 of Alt2-2, that is, or Indicate the selected model or send the selected model ID to the UE, or indicate that the NW has not selected a model that meets the requirements, and instruct the UE to perform other operations, such as Use traditional non-AI CSI feedback.

步骤3：UE根据接收的NW所选模型指示信息确定NW所选的模型或UE的反馈方式。Step 3: The UE determines the model selected by the NW or the feedback mode of the UE according to the received NW selected model indication information.

上述实施例中，模型管理包含基于模型ID的管理和基于功能ID的管理。上述的通过模型ID指示所选择的模型，也可以通过功能ID指示的方式指示所选的模型。即模型ID可以用功能ID替代。In the above embodiment, model management includes management based on model ID and management based on function ID. The above-mentioned indication of the selected model by model ID can also be indicated by function ID indication. That is, model ID can be replaced by function ID.

实施例1(实施方式1)：Embodiment 1 (implementation method 1):

在UE和gNB分别部署了M＝6个CSI生成部分模型和CSI恢复部分模型。UE和gNB经过模型识别或功能识别后，gNB给UE配置了小区标识用于指示UE当前所处的场景为outdoor场景。根据模型识别结果可知，在该场景下UE和gNB可确定的有N＝2个CSI生成部分模型和CSI恢复部分模型。即UE和gNB将经过第一步骤确定候选可用的模型个数N＝2。M=6 CSI generation partial models and CSI recovery partial models are deployed on the UE and gNB respectively. After the UE and gNB have undergone model identification or function identification, the gNB configures the UE with a cell identifier to indicate that the UE is currently in an outdoor scenario. According to the model identification results, the UE and gNB can determine N=2 CSI generation partial models and CSI recovery partial models in this scenario. That is, the UE and gNB will determine the number of candidate available models N=2 through the first step.

gNB向UE发送信令指示UE从N＝2个模型中选择1个模型，或者UE直接根据下行导频信号所测量的信道进行模型选择。可选地，UE再选择模型时，gNB向UE发送这两个CSI恢复部分模型输出的信息，用于UE对模型的选择。UE将选择的模型通过指示UE所选的模型，或者UE把所选模型的ID发送给gNB。最后gNB再向UE发送信令指示给UE是否允许UE采用所选的模型。若不允许UE采用所选的模型，UE可采用传统non-AI的方法实现CSI反馈，或者UE仍采用原来所用的CSI生成部分模型。The gNB sends a signaling to the UE to instruct the UE to select one model from N=2 models, or the UE directly selects the model based on the channel measured by the downlink pilot signal. Optionally, when the UE selects a model, the gNB sends the information output by the two CSI recovery models to the UE for the UE to select the model. The UE selects the model through Indicate the model selected by the UE, or the UE sends the ID of the selected model to the gNB. Finally, the gNB sends a signaling to the UE to indicate whether the UE is allowed to adopt the selected model. If the UE is not allowed to adopt the selected model, the UE can use the traditional non-AI method to implement CSI feedback, or the UE still uses the original CSI generation model.

UE在采用所选的模型运行一段时间后，因UE电量限制，UE可允许的模型个数减少到K个，或者可运行的模型已不可再使用。UE主动向gNB发送请求信令，指示原来的运行的模型不可用，或者可用的模型个数只剩K＝1个。UE可直接选择一个模型并所选模型的指示信息发送向gNB。或者UE再接收到gNB发送的指示信令后再确定是否选择模型。UE通过一个大小为N＝2bit指示可用的模型个数，然后再通过指示从K个模型中中选择一个模型。由于K＝1，所以不需要额外的bit再指示，gNB可根据接收的N＝2bits确定UE所选的模型。After the UE runs for a period of time using the selected model, due to the UE power limit, the number of models allowed by the UE is reduced to K, or the runnable model is no longer available. The UE actively sends a request signaling to the gNB, indicating that the original running model is not available, or the number of available models is only K = 1. The UE can directly select a model and send the indication information of the selected model to the gNB. Or the UE determines whether to select a model after receiving the indication signaling sent by the gNB. The UE indicates the number of available models through a size of N = 2 bits, and then Indicates the selection of a model from K models. Since K = 1, no additional bit is required for indication, and the gNB can determine the model selected by the UE based on the received N = 2 bits.

特别地，当UE监测到没有一个模型可用时，即K＝0。UE把K的值指示上报给gNB后，由gNB向UE发送信令指示信息确定是否让UE采用non-AI的CSI反馈。In particular, when the UE detects that no model is available, that is, K = 0. After the UE reports the value of K to the gNB, the gNB sends a signaling indication message to the UE to determine whether to let the UE use non-AI CSI feedback.

实施例2(实施方式2)：Embodiment 2 (implementation method 2):

假设M和N的参数仍同实施例1。gNB向UE发送模型选择的指示信息，指示UE向gNB发送M或N个CSI生成部分模型压缩后的信息和根据下行导频如CSI-RS确定的各子带的信道信息的特征向量信息，然后gNB根据接收的这些信息从M或N个模型中选择1个模型。gNB把所选的模型信息直接通过模型ID或功能ID指示给UE，或者gNB通过和指示所选的模型。Assume that the parameters of M and N are still the same as those in Embodiment 1. The gNB sends the indication information of model selection to the UE, indicating that the UE sends the compressed information of M or N CSI generation partial models and the characteristic vector information of the channel information of each subband determined according to the downlink pilot such as CSI-RS to the gNB, and then the gNB selects one model from the M or N models according to the received information. The gNB indicates the selected model information to the UE directly through the model ID or function ID, or the gNB indicates the selected model information to the UE directly through the model ID or function ID, or the gNB sends ... and Indicates the selected model.

若N的值不能根据gNB配置的参数确定，而是由gNB指示。gNB通过一个大小为M＝6bits或指示所选的N个模型，其中和分别表示gNB选择N个模型和从M个模型中选择N个模型。然后再通过指示选择的是哪一个模型，或者gNB直接把所选模型ID或功能ID指示给UE。特别地，若gNB没能选择满足性能要求的模型，gNB向UE发送一个指示信息指示UE执行传统non-AI的CSI反馈。If the value of N cannot be determined by the parameters configured by the gNB, but is indicated by the gNB, the gNB uses a size of M = 6 bits or Indicates the selected N models, where and Respectively, it means gNB selects N models and selects N models from M models. Then, Indicates which model is selected, or the gNB directly indicates the selected model ID or function ID to the UE. In particular, if the gNB fails to select a model that meets the performance requirements, the gNB sends an indication message to the UE to instruct the UE to perform traditional non-AI CSI feedback.

实施例3(实施方式3)：Embodiment 3 (implementation method 3):

同实施例1，当UE接收到gNB发送的模型选择指示信息后，首先从M个模型中选择N个模型，或者从N个模型中选择K个可用的模型。UE把它所选的N个或K个模型的指示信息发送给gNB。As in Embodiment 1, after the UE receives the model selection indication information sent by the gNB, it first selects N models from the M models, or selects K available models from the N models. The UE sends the indication information of the N or K models selected by it to the gNB.

gNB根据接收的UE所选的模型指示信息和UE发送N个或K个模型的输入信息和输出信息，从N个或K个选择1个最优模型。其中N个或K个模型的输入信息可以相同或不同。UE选择周期、半持续、非周期上报或通过事件触发中的一种方式，把这些模型的输入信息和输出信息通过一次或多次上报给gNB。然后gNB把所选的1个模型信息通过或指示给UE，或者直接通过把选择模型ID或功能ID信息发送给UE。The gNB selects an optimal model from N or K models according to the received model indication information selected by the UE and the input information and output information of N or K models sent by the UE. The input information of the N or K models can be the same or different. The UE selects a periodic, semi-continuous, aperiodic reporting method or an event trigger method to report the input information and output information of these models to the gNB once or multiple times. Then the gNB reports the selected model information to the gNB through or Indicate to the UE, or directly send the selected model ID or function ID information to the UE.

UE根据接收gNB发送的指示信息确定UE所采用的CSI生成部分模型，或者确定是否采用传统non-AI方法反馈CSI。The UE determines the CSI generation model adopted by the UE based on the indication information sent by the gNB, or determines whether to use the traditional non-AI method to feedback the CSI.
