Abstract: According to one embodiment of the present invention, a method by which a terminal transmits uplink data by using a preconfigured uplink resource (PUR) in a wireless communication system supporting a narrowband Internet of Things (NB-IoT) system comprises the steps of: receiving information related to the PUR for transmitting uplink data in an RRC connected state; and transmitting the uplink data by using the PUR in an RRC idle state. The information related to the PUR includes information indicating a particular carrier for monitoring a first search space related to the PUR, and when the first search space overlaps a second search space in which downlink control information (DCI) related to a particular operation is transmitted, the second search space has priority.

Abstract: A method by which a terminal transmits uplink control information (UCI) in an unlicensed band and a device using the method are provided. The method generates data and first UCI including information necessary to decode the data, and transmits, to a base station, the data and the first UCI through a physical uplink shared channel (PUSCH) in an unlicensed band, wherein the first UCI further includes information necessary to decode the second UCI when second UCI is transmitted to the base station together with the data and the first UCI through the PUSCH.

Abstract: The present specification discloses a method for a terminal receiving a narrowband PDCCH in a narrowband-supporting wireless communication system, and a device therefor. Specifically, the method comprises the steps of: receiving search space-related information from a base station via upper layer signaling; and receiving, from the base station, a narrowband PDCCH from the search space, which comprises one or more narrowband PDCCH candidates, wherein the search space includes a first search space defined on the basis of the search space-related information, and a second search space having the same type as that of the first search space, wherein, when one portion of the first search space and the second search space overlap, at least one NPDCCH candidate, in the first search space, overlapping with the second search space is dropped.

Abstract: The present disclosure suggests a method for adjusting the size of a contention window of a base station/terminal. The method comprises transmitting a physical downlink shared channel (PDSCH) to a user equipment (UE) through a frequency bandwidth, receiving an acknowledgement/negative-acknowledgement (ACK/NACK) signal for the PDSCH from the UE, and adjusting the contention window based on the ACK/NACK signal, wherein based on the frequency bandwidth overlapping with a plurality of frequency bands, the BS adjusts the contention window for each of the plurality of frequency bands based on the ACK/NACK signal.
