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: Disclosed is a method for transmitting and receiving signals to enable a terminal to perform a random access channel procedure (RACH procedure) in an unlicensed band. In particular, the method comprises: transmitting an uplink signal including a first physical random access channel (PRACH) and a first physical uplink shared channel (PUSCH) to a base station; and receiving, from the base station, a downlink signal related to contention resolution in response to the uplink signal, wherein a power ramping counter is used to set the transmission power of the uplink signal, and the value of the power ramping counter may be increased on the basis of a transmission spatial beam for the transmission of the uplink signal being configured in the same manner as a transmission spatial beam for the transmission of a PRACH prior to the uplink signal.

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).
