1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, a first radio resource control (RRC) release message including information related to a suspend configuration and information related to a configured grant (CG) configuration for a small data transmission (SDT);
performing an SDT procedure based on the information related to the CG configuration for the SDT while the terminal is in an RRC inactive;
receiving, from the base station, a second RRC release message without the information related to the suspend configuration; and
releasing the CG configuration for the SDT based on the second RRC release message without the information related to the suspend configuration while the terminal is in an RRC idle state.
