Abstract: According to an embodiment of the present disclosure, a user equipment (UE) may perform a channel access procedure for a scheduled uplink (UL) transmission on a shared spectrum based on a random access response. When it is indicated that the scheduled UL transmission is associated with channel occupancy initiated by a base station (BS) and the UE needs to perform channel sensing for the scheduled UL transmission, the UE may perform the channel access procedure for the scheduled UL transmission, based on whether reception of the random access response and the scheduled UL transmission are confined within a same period among periods configured in the shared spectrum.

Abstract: According to an embodiment of the present disclosure, a user equipment (UE) may receive configuration information for channel access based on UE-initiated channel occupancy on a shared spectrum and determine whether an uplink (UL) transmission associated with the UE-initiated channel occupancy is allowed during a first period that is based on the configuration information. Based on that resources for the UL transmission associated with the UE-initiated channel occupancy in the first period are related to a contention-based random access procedure, the UE may determine that the UL transmission associated with the UE-initiated channel occupancy is not allowed in the first period.

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: A method and a device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present disclosure, comprise the steps of: determining a physical uplink control channel (PUCCH) resource for transmitting the PUCCH; and transmitting the PUCCH through the PUCCH resource. The PUCCH resource is determined to be one of 16 PUCCH resources in a PUCCH resource set. The PUCCH resource set is a PUCCH resource set for a state in which there is no dedicated PUCCH resource configuration in a terminal. The number of physical resource blocks (PRBs) of the PUCCH resource can be determined on the basis of a received system information block (SIB).

Abstract: A method of a user equipment (UE) in a wireless communication system includes receiving resource allocation information related to a configured grant (CG)-based uplink transmission, receiving configuration information indicating multiplexing between CG uplink control information (CG UCI) and hybrid automatic repeat request acknowledgement (HARQ-ACK) information, performing joint encoding of the CG UCI and the HARQ-ACK information based on the configuration information, and transmitting a CG physical uplink shared channel (CG PUSCH) based on the resource allocation information. The joint-encoded information is multiplexed in the CG PUSCH. A beta offset value corresponding to one of a first index, a second index, or a third index related to a beta offset for the HARQ-ACK information is applied to the joint encoding.
