Abstract: An electronic device is provided. The electronic device includes a RFIC to convert data transmitted from the a communication processor into a RF signal and output the RF signal, and an antenna configured to receive the RF signal and radiate an electromagnetic field, the communication processor is configured to receive, from a BS, a reference signal for identifying a state of a downlink channel between the electronic device and the BS through the antenna and the RFIC, based on the reference signal and association information between the downlink channel and an uplink channel and between the electronic device and the BS, identify the uplink channel, based on the identified uplink channel, identify a precoder for the uplink channel, based on the identified precoder, precode uplink data and a DMRS, and transmit a signal based on the precoded data to the BS using at least some of the RFIC and the antenna.

Abstract: 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.
