摘要： A method which may be performed by a base station, may include obtaining a predicted transmission configuration indicator (TCI) subset for a user equipment (UE); and determining the TCI subset corresponding to the UE based on the predicted TCI subset. The step of obtaining the predicted TCI subset in the solution may be implemented by using a trained artificial intelligence model. Since the beams in the predicted TCI subset may fit the movement trend of the UE, then the target serving beam for the UE when performing serving beam switching may belong to the predicted TCI subset with a greater possibility, thus reducing the occurrence of high delay scenarios when the UE performs the serving beam switching, and thus reducing the beam switching delay.
