               1. 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; and 
                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.
