Abstract: Provided are a method and device for monitoring a downlink control channel of a terminal in a wireless communication system. The terminal receives configuration information which informs of the position of an SSB or configuration information which informs of the position of an LTE CRS, and receives configuration information which informs of a monitoring occasion for detecting a wake up signal (WUS). If first PDCCH monitoring for detecting the wake up signal is not required since a resource of the monitoring occasion overlaps with a resource of the SSB and/or a resource of the LTE CRS, the terminal performs second PDCCH monitoring in a next discontinuous reception (DRX)-on duration.

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.
