1. A method performed by a terminal, the method comprising:
receiving, in a serving cell from a base station, a radio resource control (RRC) reconfiguration message, wherein:
the RRC reconfiguration message comprises one or more first identifiers; and
one or more second identifiers are determined based on a specific set of first identifiers;
receiving, in the serving cell from the base station, a downlink control information (DCI) associated with a physical downlink control channel (PDCCH) order, wherein the DCI comprises a field for a second identifier;
performing a second uplink transmission in a cell determined based on the field for the second identifier;
receiving, from the base station, a first medium access control (MAC) protocol data unit (PDU), wherein the first MAC PDU comprises a field for a first identifier for cell switch; and
performing a first uplink transmission in a cell determined based on the field for the first identifier,
wherein:
the second identifier indicates the serving cell in case that the second identifier is equal to a specific integer; and
the second identifier indicates a Layer1/Layer2-Triggered Mobility (LTM) candidate cell in case that the second identifier is determined based on the specific set of first identifiers.
