1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, first discontinuous reception (DRX) configuration information for a first DRX group and second DRX configuration information for a second DRX group;
performing physical downlink control channel (PDCCH) monitoring for the first DRX group in a first active time based on the first DRX configuration information, and performing PDCCH monitoring for the second DRX group in a second active time based on the second DRX configuration information;
receiving, from the base station, a medium access control (MAC) control element (CE) associated with a DRX cycle in one of the first DRX group and the second DRX group; and
using one DRX cycle for each of the first DRX group and the second DRX group, based on the MAC CE,
wherein the first DRX group and the second DRX group are determined based on a frequency range (FR).
