US 2023/0412239 A1 · METHOD PERFORMED BY A BASE STATION, BASE STATION AND COMPUTER-READABLE STORAGE MEDIUM

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.

Dependent claims

A device of a base station, the device comprising;

at least one transceiver;
and
at least one processor electrically connected to the at least one transceiver,
wherein the at least one processor is configured to:
obtain at least one measurement report (MR) of a user equipment (UE);
identify a predicted transmission configuration indicator (TCI) subset from a set of TCI states configured to the UE based on the at least one MR of the UE;
determine whether to change an active TCI subset based on the predicted TCI subset,
in case that it is determined that the active TCI subset is changed, transmit, to the UE, a control signal for activating the predicted TCI subset from the set of TCI states,
wherein each TCI state of the set of TCI states comprises a beam indicator.
