1. A method performed by a terminal in a wireless communication system, the method comprising:
identifying a first status for a secondary cell (SCell) of the terminal;
identifying whether a first medium access control (MAC) control element (CE) or a second MAC CE is received from a base station, wherein the first MAC CE indicates whether the SCell is transitioned into an activated state or a deactivated state, and the second MAC CE indicates whether the SCell is transitioned into the activated state or a dormant state; and
identifying a second status for the SCell based on the first status and the first MAC CE, in case that the first MAC CE is received from the base station and the second MAC CE is not received from the base station,
wherein, in case that the first status for the SCell is the dormant state and the first MAC CE indicates that the SCell is transitioned into the activated state, the second status for the SCell is identified to be maintained as the dormant state, and
wherein, in case that the first status for the SCell is the dormant state and the first MAC CE indicates that the SCell is transitioned into the deactivated state, the second status for the SCell is identified as the deactivated state.
