1. A user equipment (UE) in a wireless communication system, the UE comprising:
a transceiver configured to receive reservation information including an indication, wherein the indication includes a configuration identifier (ID) of secondary cell group (SCG) for indicating a configuration status of the SCG; and
a processor operably coupled to the transceiver, the processor configured to:
determine, based on the indication, whether a candidate primary cell or primary secondary cell (PCell/PSCell) is reserved;
store, based on a determination that the candidate PCell/PSCell is reserved, the reservation information, cell group (CG) information, and one or more execution conditions associated with the reserved PCell/PSCell;
retrieve, after performing a first UE operation, the stored CG information and the one or more execution conditions associated with the reserved PCell/PSCell;
determine whether the one or more execution conditions are met for a reserved PCell/PSCell; and
upon determination that the one or more execution conditions are met, apply the stored CG information of the reserved PCell/PSCell to a second UE operation.
