Abstract: The present invention provides a method for transmitting and receiving a downlink signal between a terminal and a base station in a wireless communication system supporting an unlicensed band, and a device supporting the method. As a specific example, the present invention includes a method for: transmitting and receiving a physical downlink control channel (PDCCH) signal in an unlicensed band so that a base station and a terminal transmit and receive system information associated with a particular synchronization signal/physical broadcast channel (SS/PBCH) block; and, based on the PDCCH signal, transmitting and receiving a PDSCH signal including the system information.

Abstract: A method and device for transmitting and receiving signals in a wireless communication system according to one embodiment of the present invention stay awake by means of a DRX operation and transmit a PUCCH including UCI. An interlace for transmitting the PUCCH is on the basis of (i) an index of a first interlace being set lower than an index of a second interlace, and (ii) the number of PRBs for transmitting the UCI being less than or equal to the number of PRBs of the first interlace, so that the PUCCH is determined as the first interlace among the first interlace and the second interlace.

Abstract: Performing a random-access channel procedure (RACH procedure) by a terminal in an unlicensed band. Specifically, a method may include: transmitting message A including a first physical random-access channel (PRACH) and a first physical uplink shared channel (PUSCH) to a base station; and receiving contention resolution-related message B from the base station in response to message A, wherein a power ramping counter is used to configure transmission power of message A, and the power ramping counter has a value which increases based on that a transmission spatial beam for transmission of message A is configured to be identical to a transmission spatial beam related to transmission of a PRACH preceding message A.
