- AI models are models that can handle a variety of tasks. They have the ability to self-learn and self-adapt, and can dynamically adjust and make decisions based on changes in the environment. AI models can also be called machine learning (ML) models, and the two are equivalent or interchangeable.
- ML machine learning
- AI models can be composed of neural networks.
- a neural network is a computing model composed of multiple interconnected neuron nodes, where the connection between nodes represents the weighted value from the input signal to the output signal, called the weight; each node performs a weighted summation on different input signals and outputs them through a specific activation function.
- a1, a2, ..., an and 1 are the inputs of the neuron
- w1, w2, ..., wn and b represent weights
- Sum represents the summation function
- f represents the activation function
- t is the output result.
- a simple neural network is shown in Figure 3, which includes an input layer, a hidden layer, and an output layer. Through different connections, weights, and activation functions of multiple neurons, different outputs can be generated, thereby fitting the mapping relationship from input to output.
- Each upper-level node is connected to all of its lower-level nodes.
- This fully connected model can also be called DNN, or deep neural network.
- An AI model can be trained and obtained through the process of data set construction, training, verification and testing. Training can be divided into offline training and online training. A static training result can be obtained by offline training of the data set, which can be called offline training here.
- the network equipment can continue to collect more data and perform real-time online training to optimize the parameters of the AI model to achieve better inference and prediction results. After obtaining the AI model, by inputting the current information into the AI model, the corresponding model output can be inferred.
- AI When AI is used in wireless communications, it can be divided into single-end models and dual-end models.
- the single-end model can be used by deploying it only on one side of the terminal device or network device, and the training of the AI model can also be performed on only one side;
- the dual-end model needs to be deployed in pairs on the terminal device and network device side, and the models on both sides need to be trained together, that is, the models deployed on both sides are corresponding and cannot be used or updated separately.
- an AI model for channel state information (CSI) feedback is a typical dual-end model.
- FIG4 for a schematic diagram of the dual-end AI model structure for CSI feedback.
- an AI model for encoding (encoder) is deployed on the terminal side
- a corresponding AI model for decoding (decoder) is deployed on the network side.
- the terminal device outputs CSI quantization bits based on the encoder model, typically PMI bits, and then feeds back to the network device through the uplink channel (PUSCH/PUCCH).
- the network device uses the CSI quantization bits (PMI) fed back by the terminal as the input of the decoder model, thereby outputting channel information corresponding to the input on the terminal side, such as the feature vectors of each subband, etc., for downlink precoding.
- the terminal device also needs to monitor the model performance and report to the network device when the model performance is not good, so that the network device can update the model (for example, update the model structure or update the model parameters). Since the AI models on both sides are matched, if the network device updates the model, it needs to notify the terminal device through signaling so that the terminal device also updates to the corresponding AI model. Otherwise, the output result of the network device will be unusable.
- the above-mentioned AI model based on dual-end deployment can not only be used for CSI feedback, but also for other processing methods with corresponding operations/structures on the terminal device and network device sides, such as channel coding-channel decoding, modulation-demodulation, pilot generation-channel estimation, transceiver RF signal processing, etc. It is only necessary to train a set of AI models on the corresponding terminal device side and network device side.
- the network device can instruct the terminal device to update the model through signaling (for example, replace an AI model or adjust model parameters).
- the network device also needs to perform corresponding model updates so that the AI models on both sides still match each other. If the updates of the AI models on both sides are not completely synchronized, the output of the receiving AI model will be wrong, thereby affecting the information transmission between the terminal device and the network device.
- an embodiment of the present application provides a wireless communication method, wherein when the corresponding dual-end AI model is used on the terminal device side and the network device side, if the AI model on the terminal device side is updated or reconfigured, the terminal device can determine the time when the AI model configured by the network device starts to be applied based on the model application time reported to the network device, or based on the model application time configured by the network device. In this way, it can be ensured that the model application time on both sides is the same, thereby ensuring that the output of the AI model is available, and improving the performance of the communication system.
