Abstract: Provided are a method for a terminal transmitting an uplink control channel in a wireless communication system, and a device using same. The method comprises: determining the overlapping or not between a first physical uplink control channel (PUCCH) and a second PUCCH; and determining a transmission method for the first PUCCH and the second PUCCH on the basis of the determining. Here, the first PUCCH is an uplink control channel that is frequency division multiplexed (FDM) with a data channel, and the second PUCCH is an uplink control channel that is time division multiplexed (TDM) with the data channel.

Abstract: A method of performing channel access on an unlicensed band by a user equipment, includes sensing a carrier of an unlicensed band for transmitting an uplink signal; and transmitting the uplink signal when power detected by sensing the carrier is less than an energy detection threshold that is configured by the user equipment, wherein the energy detection threshold is configured to be equal to or less than a maximum energy detection threshold determined by the user equipment, the maximum energy detection threshold is determined adaptively to a bandwidth of the carrier using a decibel value of a ratio between a reference bandwidth and the bandwidth of the carrier, and the maximum energy detection threshold is configured to be equal to or greater than a first power value which is a sum of a lower bound of the maximum energy detection threshold for the reference bandwidth and the decibel value.

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.
