Abstract: Disclosed is a base station of a wireless communication system. Each base station for wireless communication comprises: a communication module; and a processor. The processor can receive signaling about a bandwidth part (BWP) from the base station, determine, on the basis of the signaling, an activated BWP among one or more BWPs set in an unlicensed band, and monitor a physical downlink control channel (PDCCH) in the activated BWP.

Abstract: The present invention relates to a method, device, and system for downlink data reception and HARQ-ACK transmission in a wireless communication system. According to the present invention, in the method, device, and system for downlink data reception and HARQ-ACK transmission, a first physical downlink control channel (PDCCH) for scheduling of a first physical downlink shared channel (PDSCH) is received, and a second PDCCH for scheduling of a second PDSCH is received. Thereafter, uplink control information (UCI) including a hybrid automatic repeat request (HARQ)-acknowledge (ACK) codebook for the first PDSCH and the second PDSCH is transmitted to a base station.

Abstract: A UE in a wireless communication system is disclosed. The UE includes a communication module and a processor for controlling the communication module. The processor determines a first cyclic shift (CS) value based on hybrid automatic repeat request acknowledgment (HARQ-ACK) information representing a response to a downlink channel having been received from a base station, determines a CS offset based on request information representing a request to be transmitted from the UE to the base station, determines a second CS value representing a degree of cyclic-shifting a base sequence to be used in a physical uplink control channel (PUCCH) based on the first CS value and the CS offset, and transmits the PUCCH for simultaneous transmission of the request information and the HARQ-ACK information using a sequence generated by cyclic-shifting the base sequence based on the second CS value.

Abstract: A method for receiving downlink transmission by a terminal comprises the steps of: performing uplink transmission, which is related to channel occupancy shared between a base station and the terminal, to the base station; and receiving, from the base station, downlink transmission performed after a gap from a time point at which the base station has received the uplink transmission, wherein the downlink transmission is performed on the basis of channel access performed by the base station, the channel access is performed on the basis of the gap, and information included in the downlink transmission and a resource through which the downlink transmission is performed are determined on the basis of whether the base station has configured, for the terminal, a threshold value of energy detection for the channel occupancy.

Abstract: A base station of a wireless communication system is disclosed. The base station of the wireless communication includes a communication module; and a processor configured to control the communication module. The processor receives a radio resource control (RRC) signal from abase station of the wireless communication system through the communication module and determines a time-frequency resource corresponding to at least one resource-set indicated by the RRC signal. The processor receives a physical control channel from the base station through the communication module, determines a time-frequency resource domain in which physical data channel reception of the terminal is scheduled by the physical control channel, and receives a physical data channel based on a time-frequency resource in which the physical data channel reception of the terminal is scheduled and a time-frequency resource in which the at least one resource-set overlap. The resource-set is a set of time-frequency resources.
