Abstract: Provided are a discontinuous reception (DRX) operation method of a terminal in a wireless communication system and an apparatus applying the method. The method comprises the steps of: receiving, from a base station, first configuration information which indicates a monitoring occasion for detecting first DCI comprising information that indicates whether the terminal has woken up; receiving, from the base station, second configuration information which indicates an operation to be applied to the terminal when the first DCI is not detected; monitoring a first PDCCH in order to detect the first DCI in the monitoring occasion; and when the first DCI fails to be detected in the monitoring occasion, monitoring a second PDCCH for detecting not the first DCI but second DCI in a next DRX-on duration on the basis of the second configuration information.
