[0039] Optionally, the model in the embodiments of the present application can be understood as an artificial intelligence (AI) model. There are many ways to implement AI models, such as neural networks, decision trees, support vector machines, Bayesian classifiers, etc. The following embodiments are described using neural networks as an example, but do not limit the specific type of AI model.

[0040] Optionally, a neural network in an embodiment of the present application may be as shown in FIG2A , including an input layer, a hidden layer, and an output layer, wherein the input of the input layer is X1, X2…X n , the output of the corresponding output layer is Y. The neural network is composed of neurons, which can be shown in Figure 2B.

Common activation functions include but are not limited to the sigmoid function, the tanh function, and the rectified linear unit (ReLU).

[0041] Optionally, the parameters of the neural network can be optimized using a gradient optimization algorithm. A gradient optimization algorithm is a type of algorithm that minimizes or maximizes an objective function (also known as a loss function), and the objective function is often a mathematical combination of model parameters and data. For example, given the model input data X and its corresponding label Y, a neural network model f(.) is constructed. After the model is constructed, the predicted output f(x) can be obtained based on the input data x, and the difference between the predicted value and the true value (f(x)-Y) can be calculated. This is the loss function. The purpose of training a neural network model is to find appropriate weights w and biases b to minimize the value of the corresponding loss function. The smaller the loss value, the closer the model is to the true situation.

[0042] Optionally, the optimization algorithms used in the models in the embodiments of the present application are mostly based on the error back propagation (BP) algorithm. The basic idea of ​​the BP algorithm is that the learning process consists of two processes: forward propagation of the signal and back propagation of the error. During forward propagation, the input sample is transmitted from the input layer, processed layer by layer by each hidden layer, and then transmitted to the output layer. If the actual output of the output layer does not match the expected output, the error back propagation stage is entered. Error back propagation is to propagate the output error back to the input layer layer by layer through the hidden layer in some form, and distribute the error to all units in each layer, thereby obtaining an error signal for each unit in each layer. This error signal is used as the basis for correcting the weights of each unit. This process of adjusting the weights of each layer through forward propagation of the signal and back propagation of the error is repeated over and over again. The process of constantly adjusting the weights is the learning and training process of the model. This process continues until the error of the model output is reduced to an acceptable level, or until a pre-set number of learning cycles is reached.

[0043] Optionally, the optimization algorithms used in the model in the embodiment of the present application include but are not limited to: Gradient Descent, Stochastic Gradient Descent (SGD), mini-batch gradient descent (small batch gradient descent), Momentum, Nesterov (the name of the inventor, specifically stochastic gradient descent with momentum), Adaptive gradient descent (Adaptive gradient descent, Adagrad), Adaptive incremental (Adadelta), Root mean square error (RMSprop), Adaptive moment estimation (Adam), etc. When the error is back-propagated, these optimization algorithms all calculate the derivative / partial derivative of the current neuron based on the error / loss obtained by the loss function, add the influence of the learning rate, the previous gradient / partial derivative / derivative, etc., to obtain the gradient, and pass the gradient to the previous layer.

[0044] Optionally, the model in the embodiments of the present application may also be referred to as an AI model, an AI unit, a machine learning (ML) model, an ML unit, an AI structure, an AI function, an AI feature, a machine learning model, a neural network, a neural network function, a neural network function, etc.; or, the AI ​​unit / AI model may refer to a processing unit that can implement specific algorithms, formulas, processing procedures, capabilities, etc. related to AI; or, the AI ​​unit / AI model may be a processing method, algorithm, function, module or unit for a specific data set; or, the AI ​​unit / AI model may be a processing method, algorithm, function, module or unit running on AI / ML related hardware such as a graphics processing unit (GPU), a neural network processor (NPU), a tensor processing unit (TPU) or an application-specific integrated circuit (ASIC), and this application does not specifically limit this. Optionally, the specific data set may include the input and / or output of the AI ​​unit / AI model.

This application does not make any specific limitations on this.

[0089] (1) A first communication device receives fourth information sent by a second communication device; wherein the fourth information is used to indicate that the second communication device supports adjustment of the first part of the adaptation layer, or indicates that the second communication device does not support adjustment of the second part of the adaptation layer; for example, when a network (NW) transmits a model to a user equipment (UE, also referred to as a terminal or terminal device), the UE may choose to support subsequent adjustment of part of the adaptation layer, and the unsupported part of the adaptation layer is equivalent to a fixed layer, i.e., it cannot be adjusted subsequently, and feedback is provided to the NW; or, when the UE transmits adaptation layer information to the NW, the NW may choose to support subsequent adjustment of part of the adaptation layer, and the unsupported part of the adaptation layer is equivalent to a fixed layer, i.e., it cannot be adjusted subsequently, and feedback is provided to the UE;

[0097] In an optional implementation, when the model is transmitted from the NW to the UE, the corresponding adaptive layer interaction process includes: the NW indicates the adaptive layer information to the UE, and then the UE feeds back to the NW whether the adaptive layer information is successfully received or successfully applied; or, the UE indicates the adaptive layer information to the NW, and then the NW feeds back to the UE whether the adaptive layer information is successfully received or successfully applied.
