Abstract: A method and a device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present disclosure, comprise transmitting a PRACH, and receiving an RAR on the basis of the PRACH. The PRACH is transmitted within one or two PRACH slots. The one or two PRACH slots are determined from among N number of slots corresponding to reference slots. 60 kHz SCS can be applied to the reference slots on the basis of the application of one from among 480 kHz SCS and 960 kHz SCS to the N number of slots.

Abstract: Provided is a method for receiving, by a user equipment (UE), a feedback from a base station in a wireless communication system supporting narrowband (NB)-internet of things (IoT). Specifically, the UE receives, from the base station, a preconfigured uplink (UL) resource (PUR) configuration via RRC signalling, transmits, to the base station, uplink data on the PUR when the UE is in an idle mode, and receive, from the base station, the feedback for the uplink data. The feedback is configured to be received on an NPDCCH after a specific time has passed from the PUR transmission.

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).
