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: Provided are a method and device for monitoring a PDCCH of a terminal in a wireless communication system. The terminal receives first setting information that provides notification of a monitoring occasion for detecting a wake up signal (WUS), and performs monitoring for detecting the wake up signal in the monitoring occasion. If the wake up signal is not detected in the monitoring occasion, whether to monitor a PDCCH in the next DRX-on period is determined on the basis of second setting information that indicates the operation to be applied to the terminal when the terminal does not detect the wake up signal.
