[0082] 6G systems can provide more dimensions of AI services, mainly including the following three aspects:

[0083] AI-enabled connectivity. That is, using AI methods to improve the performance of communication, such as using AI for beam management.

[0084] Computing power service. That is, the network side can provide computing power to the terminal side, such as helping the terminal to perform model training, model inference, etc.

[0085] Extreme AI service. That is, the transmission pipeline of the network is enhanced to improve the experience of AI application services.

[0086] In a positioning system, a terminal needs to receive PRS (Positioning Reference Signal) from multiple base stations, not only including the PRS of the serving base station, but also including the PRS of other adjacent cells for positioning. Therefore, the terminal not only needs the NW additional condition of the current serving cell, but also needs the NW additional condition of other non-serving cells participating in positioning.

[0087] The NW additional condition is used to describe information related to network configuration or network implementation. For example, the downtilt angle of the network side antenna, the beam width, etc. The terminal side needs to understand the network additional condition when collecting data, managing models, etc. to ensure the consistency of the characteristics of the training data and the model inference data. On the other hand, the network side does not want to expose specific network private information to the terminal, so the concept of associated ID is introduced. Specifically, the network side will map a certain NW additional condition to an associated ID, and the terminal side does not know the real physical meaning of a certain associated ID. The terminal side only needs to compare the associated ID received when collecting training data with the associated ID received when performing model inference, to determine whether the current model is suitable for the network environment.

[0088] Therefore, the present disclosure proposes a communication method and device, a communication system, a communication device, and a storage medium. The first network device sends first information to the terminal, so that the terminal obtains the NW additional condition of the serving cell and the NW additional condition of the non-serving cell.

[0089] The method proposed in the present disclosure is applicable to various communication systems, including but not limited to 4G, 5G, 5G-advance, and subsequent communication technologies (such as 6G, etc.).
