Abstract: The present disclosure discloses a method for receiving, by a terminal, a physical downlink control channel (PDCCH) in an unlicensed band. In particular, the method comprises transmitting, to a base station, a message A including a first physical random access channel (PRACH) and a first physical uplink shared channel (PUSCH), according to transmission power set by a power ramping counter, and performing a random access procedure (RACH procedure) on the base station by receiving, from the base station, a message B related to contention resolution in response to the message A, wherein a value of the power ramping counter may increase on the basis that a transmission spatial beam for transmission of the message A is configured identically to a transmission spatial beam related to transmission of a PRACH prior to the message A.

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 the steps of: determining a physical uplink control channel (PUCCH) resource for transmitting the PUCCH; and transmitting the PUCCH through the PUCCH resource. The PUCCH resource is determined to be one of 16 PUCCH resources in a PUCCH resource set. The PUCCH resource set is a PUCCH resource set for a state in which there is no dedicated PUCCH resource configuration in a terminal. The number of physical resource blocks (PRBs) of the PUCCH resource can be determined on the basis of a received system information block (SIB).
