Abstract: Provided are a method and a device for a terminal monitoring a physical downlink control channel (PDCCH) in a wireless communication system. A terminal transmits, to a base station, time information notifying of a specific time, and receives, from the base station, a particular PDCCH which is used for notifying that the terminal will be monitoring a PDCCH during a time duration. The terminal monitors the PDCCH during the time duration, wherein the terminal monitors (receives) the particular PDCCH at a time which is within from the starting point of the time duration to before the specific time.
