1. A method for operating a user equipment (UE) in a wireless communication system, the method comprising:
acquiring secondary-cell activation state indicator (SCASI) information from received downlink control information (DCI); and
determining a state corresponding to at least one secondary cell configured for the UE or reconfigured by the UE based on the SCASI information from the received DCI, wherein the state includes an activation state and an inactivation state,
wherein the DCI has a plurality of bits indicating the SCASI information, and
wherein a number of the bits is the same as a number of the at least one secondary cell.
