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 by which a terminal transmits data in an unlicensed band, and an apparatus using the method are provided. The method comprises: transmitting data to a base station through a physical uplink shared channel (PUSCH) in the unlicensed band; and receiving, from the base station, acknowledgement/negative acknowledgement (ACK/NACK) information about the data in the unlicensed band, wherein the terminal receives, from the base station, timeline information notifying of a time relationship between the PUSCH transmission time point and the ACK/NACK information reception time point.

Abstract: Disclosed is a method of receiving a physical downlink control channel (PDCCH) through a search space (SS) set by a user equipment (UE) in a wireless communication system. The method includes transmitting first information related to the number of X slots and second information related to the number of at least one Y slot, and receiving a PDCCH through a UE-specific SS (USS) set within the at least one Y slot, based on the first information and the second information. The at least one Y slot is included in the X slots, and X and Y are positive integers.

Abstract: According to an embodiment of the present disclosure, a user equipment (UE) may receive downlink control information (DCI) in a first fixed frame period (FFP) for frame based equipment (FBE) from a base station (BS), and perform a channel access procedure for a scheduled uplink (UL) transmission based on the DCI. In a first state in which it is indicated that the scheduled UL transmission is related to channel occupancy initiated by the BS, and the UE should perform channel sensing for the scheduled UL transmission, the UE may perform the channel access procedure for the scheduled UL transmission based on whether a resource for the scheduled UL transmission allocated by the DCI is confined within the first FFP in which the DCI is received.

Abstract: A method for transmitting uplink control information of a terminal in a wireless communication system and a terminal using the method are provided. The method generates uplink control information, transmits the uplink control information to a base station using a specific PUCCH format among a plurality of physical uplink control channel (PUCCH) formats, wherein the specific PUCCH format which is used is determined on the basis of the number of symbols in the time domain used for transmission of uplink control information and the number of bits of the uplink control information.

Abstract: According to at least one of the embodiments disclosed herein, a user equipment (UE) may transmit a configured grant (CG) based physical uplink shared channel (PUSCH). However, based on that the CG-based PUSCH is transmitted in a radio resource control (RRC) Inactive state, that an RRC Release message includes at least one of information on a CG-related common search space (CSS) and information on a CG-related user-specific search space (USS), and that the PDCCH is not detected in the CG-related CSS and the CG-related USS until a specific timer expires after the CG-based PUSCH transmission, the UE may determine that the CG-based PUSCH transmission in the RRC Inactive state fails.
