Claim 7:
8. A method, performed by a base station (BS), for activating a secondary cell (SCell), the method comprising:
transmitting, to a user equipment (UE), a radio resource control (RRC) message including cell configuration information of the SCell,
wherein the cell configuration information includes a bandwidth part (BWP) identifier indicating a first downlink BWP for activation of the SCell and information related to configuration of reference signals for activation of the SCell, and
wherein the information related to configuration of the reference signals for activation of the SCell indicates an interval between the reference signals for activation of the SCell and a number of the reference signals for activation of the SCell; and
transmitting, to the UE, a medium access control (MAC) control element (CE) indicating activation of the SCell,
wherein the first downlink BWP indicated by the BWP identifier is activated at the UE, based on the interval between the reference signals for activation of the SCell and the number of the reference signals for activation of the SCell.
