Abstract: According to an embodiment of the present disclosure, a method for transmitting, by a user equipment (UE), uplink data in a wireless communication system supporting a narrowband Internet of things (NB-IoT) system includes: receiving information related to a preconfigured uplink (UL) resource (PUR) for transmitting the uplink data in an RRC connected state; and transmitting the uplink data by using the preconfigured uplink resource (PUR) in an RRC idle state. In the transmitting of the uplink data, when the preconfigured UL resource (PUR) is a dedicated resource and there is no data to be transmitted in the preconfigured UL resource (PUR), transmission of the uplink data is skipped.

Abstract: The present invention relates to a method for receiving a downlink signal and an apparatus therefor. Specifically, the method for receiving a downlink signal comprises the steps of: receiving first time offset information and second time offset information from a base station, wherein the first time offset information and the second time offset information each indicate the time offset between the reception time of a specific signal and the reception time of a specific channel associated with the specific signal, and the first time offset information is set to have a length shorter than that of the second time offset information; and monitoring the specific signal at a time position determined on the basis of one of the first time offset information and the second time offset information, wherein the one offset information is determined on the basis of the capability of a user device.

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.
