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.

Abstract: One disclosure in the present specification presents a method for a wireless device to receive a paging message. The method may comprise: a step of deciding a wake up signal occasion (WUSO) window for attempting to receive a wake up signal (WUS); and a step of monitoring a downlink control channel during a paging window so as to attempt to receive a paging message, if the WUS is received within the decided WUSO window. Here, the WUSO window may be decided according to a duration size and offset.

Abstract: This specification provides a method for transmitting an NPRACH preamble in a wireless communication system supporting TDD. More specifically, the method performed by the UE includes: receiving, from a base station, NPRACH configuration information including control information for a repetition number of NPRACH preambles including symbol groups through a higher layer signaling; and transmitting, to the base station, the NPRACH preamble repeatedly through frequency hopping of a symbol group based on the NPRACH configuration information, in which a frequency location of the symbol group is determined based on a first parameter related to a start subcarrier and a second parameter related to the frequency hopping.
