Abstract: A method by which a terminal transmits an uplink signal in an unlicensed band, and an apparatus using same are provided. The method receives, from a base station, channel occupancy information through a PDCCH and transmits the uplink signal to the base station through a configured grant uplink access (CUL) type physical uplink shared channel (PUSCH) on the basis of the channel occupancy information. The channel occupancy information indicates which sub-band of a CUL band including a plurality of sub-bands enables the terminal to transmit the CUL type PUSCH within a channel occupancy time (COT) acquired by the base station through a channel access procedure.

Abstract: Provided are a method of performing a channel access procedure by an apparatus in an unlicensed band, and an apparatus using same method. The apparatus determines a contention window size (CWS) and performs a channel access procedure with respect to a first channel on the basis of the determined contention window size. The contention window size may be adjusted on the basis of feedback information relating to a second channel. When a transmission history of the second channel, which is to be reflected in determining the contention window size, does not exist, the contention window size may be determined to be a minimum CWS value in a specific channel access priority class.

Abstract: According to an embodiment of the present disclosure, a user equipment (UE) may obtain fixed frame period (FFP)-related information, and perform clear channel assessment (CCA) for at least one FFP starting with a UE-initiated channel occupancy time (COT) for transmission of an uplink signal. The FFP-related information may include information about an FFP starting offset and information about an FFP duration or period, and the UE may identify a starting time of the FFP, based on the FFP starting offset having an orthogonal frequency division multiplexing (OFDM) symbol-level granularity.

Abstract: Disclosed is a method of transmitting a physical uplink control channel (PUCCH) by a user equipment (UE) in a wireless communication system. The method includes receiving information related to an index of a PUCCH resource set for the PUCCH and to the number of resource blocks (RBs) for the PUCCH, and transmitting the PUCCH through a PUCCH resource based on a first RB offset. A second RB offset of the PUCCH resource set is obtained based on the index, and the first RB offset is obtained by multiplying the number of RBs by the second RB offset.
