Abstract: A method and an apparatus for monitoring a PDCCH of a terminal in a wireless communication system are provided. A terminal is connected to a base station through initial access. Next, first configuration information, which notifies of a monitoring occasion for detecting a first DCI including information notifying whether the terminal wakes up, is received from the base station, and monitoring for detecting the first DCI is performed during the monitoring occasion. If the first DCI has not been detected in the monitoring occasion, whether PDCCH monitoring for detecting a second DCI is performed in the next DRX-on section is determined on the basis of second configuration information indicating an operation to be applied to the terminal when the terminal has not detected the first DCI.
