For example, AI/ML may learn from a large amount of data to discern patterns and make predictions for improving reliability of device location. The AI/ML is used for positioning and can be divided into two methods, AI/ML direct positioning and AI/ML auxiliary positioning, wherein AI/ML direct positioning refers to inputting a signal measurement result for positioning into a model, the model directly outputs a positioning result, AI/ML auxiliary positioning refers to inputting the signal measurement result for positioning into the model, and the model outputs auxiliary data for optimizing or enhancing a traditional positioning mechanism. In addition, AI/ML direct positioning can be classified into AI/ML direct positioning schemes on the terminal device side and AI/ML direct positioning schemes on the network device side. The terminal equipment side adopts an AI/ML direct positioning scheme, and because the environment and the terminal state are dynamically changed along with time, the positioning capability of the terminal equipment side is also continuously changed, and how to report the positioning capability of the terminal is an important ring in the positioning scheme.
