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: 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.
