Abstract: A base station in a wireless communication system is disclosed. Each base station in the wireless communication comprises: a communication module; and a processor. When the processor attempts to transmit a synchronization signal and PBCH block (SSB) at a SSB transmission candidate position in a discovery reference signal (DRS) transmission window, and fails to transmit an SSB at a first SSB transmission candidate location in a first DRS transmission window, the processor is configured to attempt to transmit the SSB at a second SSB transmission candidate position that is later than the first SSB transmission candidate position in the first DRS transmission window. The DRS transmission window is a time interval in which the base station can transmit the SSB. The SSB transmission candidate position indicates a time point at which the base station can start SSB transmission within the DRS transmission window.

Abstract: Disclosed are wireless communication system base stations. Each wireless communication base station comprises a communication module and a processor. When the base stations carry out DRS- and nonunicast data-multiplexed transmission, the processors select one channel access type among two channel access types according to whether both of two conditions are satisfied, the two conditions being that the duration of the DRS- and nonunicast data-multiplexed transmission is 1 ms or less, and the duty cycle of DRS transmission is 1/20 or less. Among the two channel access types, the first type is channel access in which random backoff is carried out using a variable-size contention window (CW), the size of the CW being determined according to channel access priority class; and the second type is channel access in which only single time interval-based LBT is carried out.

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. The processor generates a preemption indicator indicating a preempted resource. In this case, the resource indicated by the preemption indicator does not include an orthogonal frequency divisional multiplexing (OFDM) symbol configured as an uplink (UL) symbol by a radio resource control (RRC) signal. The processor is configured to transmit the preemption indicator to a user equipment of the wireless system based on a predetermined period.

Abstract: A base station of a wireless communication system is disclosed. The base station of wireless communication includes a communication module and a processor. The processor is configured to receive a grant for scheduling a plurality of uplink transmissions from the base station, and when the UE attempts to a first fixed duration-based channel access for a first transmission which is one of the plurality of uplink transmission and fails in the first fixed duration-based channel access, attempt to a second fixed duration-based channel access for a second transmission which is a transmission following the first transmission.

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: 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.
