1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, discontinuous reception (DRX) configuration information, wherein the DRX configuration information includes configuration information respectively corresponding to at least one DRX mode, a DRX configuration identifier corresponding to a beginning DRX mode, and common DRX configuration information, and wherein the configuration information respectively corresponding to the at least one DRX mode includes at least one information about on duration timer, or information about inactivity timer;
identifying a duration timer of a first DRX mode and an inactivity timer of the first DRX mode, based on the configuration information and the DRX configuration identifier;
performing the first DRX mode, based on the configuration information for the first DRX mode and the common DRX configuration information;
receiving, from the base station, a medium access control-control element (MAC-CE) including a DRX configuration identifier corresponding to a second DRX mode and logical channel identifier, LCID; and
starting a duration timer of the second DRX mode and an inactivity timer of the second DRX mode, based on the MAC-CE, the duration timer of the first DRX mode and the inactivity timer of the first DRX mode.
