Abstract: A communication method and an apparatus. A terminal device (or an access network device) obtains a channel feature through inference by using a channel feature extraction model, where the channel feature corresponds to a channel between the terminal device and the access network device. The terminal device (or the access network device) sends the channel feature to a location management function LMF. The LMF obtains, based on the channel feature, positioning information of the terminal device through inference by using a positioning information obtaining model. The LMF may determine location information of the terminal device based on the positioning information. An artificial intelligence model may be used to implement positioning or assist in implementing positioning of the terminal device.

The terminal determines N pieces of training data based on the first information, and N is an integer. The terminal performs model training based on the N pieces of training data, to obtain a first AI model. The network device configures the first information used to determine the N pieces of training data for the terminal. The terminal performs model training based on the N pieces of training data autonomously. Separately configuring an AI model for the terminal is not necessary and air interface overheads are reduced.
