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: 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.

Abstract: Provided are a method of adjusting uplink timing in a wireless communication system and an apparatus therefor. Specifically, a method for a user equipment to adjust uplink timing in a wireless communication system includes transmitting, to a base station, an uplink signal, receiving, from the base station, a timing advance (TA) command configured based on the uplink signal, and performing uplink transmission to the base station by applying a timing advance (TA) indicated by the TA command. The TA command may be interpreted based on subcarrier spacing of at least one frequency resource region to which the TA is to be applied.

Abstract: The present specification, relates to a method for switching Internet of Things (IoT) modes in a wireless communication system and a device therefor.
According to the present specification, the method whereby a terminal switches IoT modes in a wireless communication system comprises the steps of: transmitting, in a radio resource control (RRC) connected state, an operation mode switching request for requesting switching from a source IoT mode, which is the current operation mode of the terminal, to a base station via a predetermined physical channel; receiving, from the base station, an operation mode switching response to the operation mode switching request; and switching from the source IoT mode to a predetermined target IoT mode on the basis of the operation mode switching response.
