Abstract: The present invention relates to a method for performing a random access procedure in a wireless communication system and a device therefor, the method comprising a step for receiving NPRACH configuration information and a step for transmitting a random access preamble on the basis of the NPRACH configuration information, wherein the NPRACH configuration information includes information indicating whether only a first preamble format is supported, only a second preamble format is supported, or both the first preamble format and the second preamble format are supported. If both the first preamble format and the second preamble format are supported according to the NPRACH configuration information, the random access preamble is transmitted using the first preamble format, and, if both the first preamble format and the second preamble format are supported according to the NPRACH configuration information, the random access preamble is transmitted using the second preamble format.

Abstract: A method by which a terminal monitors a physical downlink control channel (PDCCH) in a wireless communication system, and a device therefor are provided. In the method, a terminal wakes up in a DRX cycle linked with a monitoring occasion so as to monitor a PDCCH if a wake up signal (WUS) monitoring occasion does not exist in a monitoring window for allowing the terminal to monitor the WUS.

Abstract: The present specification discloses a method for a terminal receiving a narrowband PDCCH in a narrowband-supporting wireless communication system, and a device therefor. Specifically, the method comprises the steps of: receiving search space-related information from a base station via upper layer signaling; and receiving, from the base station, a narrowband PDCCH from the search space, which comprises one or more narrowband PDCCH candidates, wherein the search space includes a first search space defined on the basis of the search space-related information, and a second search space having the same type as that of the first search space, wherein, when one portion of the first search space and the second search space overlap, at least one NPDCCH candidate, in the first search space, overlapping with the second search space is dropped.

Abstract: The present disclosure relates to a method of monitoring, by a wireless device, a downlink channel or a downlink signal. The method may include a step of receiving configuration information on a power save signal. The power saving signal can be used to signal that the downlink channel or the downlink signal should be monitored later. The configuration information may contain configuration information on an opportunity to omit the power saving signal. The method may include a step of monitoring the downlink channel or the downlink signal without monitoring the energy saving signal during the opportunity to omit. The length and/or position of the opportunity of omission can be determined according to the configuration information of a discontinuous receive cycle (DRX).
