5. A user equipment (UE), the UE comprising:
a receiver configured to receive, from a serving base station, secondary serving cell (SCell) configuration information which includes at least one of a first field and a second field, wherein the first field includes a first serving cell index (SCellIndex) to indicate a release of an SCell associated with the first SCellIndex, and wherein the second field includes a second SCellIndex to indicate an addition of an SCell associated with the second SCellIndex and a timing advance group (TAG) identifier (ID) of the SCell associated with the second SCellIndex; and
a radio resource control (RRC) processor configured to release the SCell associated with the first SCellIndex from a set of available SCells configured in the UE, add the SCell associated with the second SCellIndex to the set of available SCells configured in the UE, and reorganize a TAG corresponding to the TAG ID by including the SCell associated with the second SCellIndex.
