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: A method by which terminal transmits data in an unlicensed band, and an apparatus using the method are provided. The method comprises: transmitting codeblock groups (CBGs) to a base station by using a first resource within the unlicensed band; and re-transmitting at least one CBG, in which a negative acknowledgement (NACK) is received, of the CBGs to the base station by using a second resource within the unlicensed band, wherein the second resource is determined on the basis of the proportion of the CBGs to the at least one CBG in which the NACK is received.

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.

Abstract: Provided are a method for transmitting uplink control information (UCI) of a terminal in a wireless communication system and the UE using the method. The method includes determining a number of coded symbols for the UCI transmission and transmitting the UCI on a physical uplink shared channel (PUSCH) based on the number of coded symbols. The number of coded symbols is determined among a first value based on a payload size of the UCI and an offset value and a second value based on a radio resource control (RRC) signal.
