Abstract: Disclosed is a base station in a wireless communication system. Each base station in wireless communication comprises: a communication module; and a processor. The processor generates a hybrid automatic repeat request (HARQ)-ACK codebook comprising one or more bits and indicating whether or not reception of a channel or signal is successful, and transmits the HARQ-ACK codebook to the base station.

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: The present specification relates to a device and method for transmitting an uplink control channel in a wireless communication system. Disclosed in the present specification is a method for transmitting a physical uplink control channel by means of a UE, the method including: a step for generating a first HARQ-ACK codebook related to a first PUCCH; a step for generating a second HARQ-ACK codebook related to a second PUCCH; and a step for transmitting simultaneously the first PUCCH and the second PUCCH or one PUCCH among the first PUCCH and the second PUCCH to a base station in one slot on the basis of a plurality of indicators. According to the present embodiments, the sequence for transmitting a plurality of PUCCHs including respectively different HARQ-ACKs in one slot is clarified, and thus the targeted performance of a 5G wireless communication system intended to simultaneously provide various types of traffic (eURLLC, eMBB) can be achieved.

Abstract: A base station of a wireless communication is disclosed. A wireless communication base station comprises a communication module and a processor. The processor receives DCI of a physical downlink control channel (PDCCH) for scheduling a physical uplink shared channel (PUSCH) transmission over a plurality of slots and multiplexes hybrid automatic repeat request (HARQ)-ACK information to the PUSCH transmission by applying a value in a downlink assignment index (DAI) field of the DCI to each slot where the HARQ-ACK information is multiplexed to the PUSCH transmission over the plurality of slots.

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: 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: Provided is a method for transmitting, by a terminal, a PUSCH to a base station in a wireless communication system. The method comprises: a step for receiving, from a base station, an RRC signal including configuration information on a semi-static uplink symbol, a flexible symbol, and a downlink symbol; a step for receiving a PDCCH for scheduling a PUSCH transmission including at least one PUSCH repetition; a step for determining whether at least one of the required number of symbols for transmitting the PUSCH repetition cannot transmit the PUSCH repetition; and a step for transmitting the PUSCH repetition to the base station on the basis of the determination on whether the PUSCH repetition cannot be transmitted. When the PUSCH repetition cannot be transmitted, at least one of the symbols is a symbol designated as a semi-static downlink symbol by the configuration information.
