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: A method and device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present invention, transmits a PUCCH including UCI. With respect to a resource for transmitting the PUCCH, the PUCCH is determined to be associated with a first interlace, among the first interlace and a second interlace, on the basis that: (i) the first interlace, and the second interlace having a higher index than that of the first interlace are configured by means of information on the PUCCH resource; and (ii) the number of physical resource blocks (PRBs) for transmitting the UCI is equal to or less than the number of PRBs of the first interlace.

Abstract: A method and device for transmitting and receiving a signal in a wireless communication system, according to one embodiment of the present invention, perform a 2-step or 4-step random access process in a shared spectrum. In order to transmit a PUSCH corresponding to an RAR of the 4-step random access process or a fallback-RAR of the 2-step random access process, a channel access type for the PUSCH is determined on the basis of a specific field of an RAR grant in the RAR.

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).
