Abstract: A terminal of a wireless communication system comprises a communication module and a processor for controlling the communication module. The processor generates a hybrid automatic repeat request (HARQ)-ACK codebook including one or more bits indicating whether reception of a channel or signal is successful, and transmits the HARQ-ACK codebook to a base station of the wireless communication system. The HARQ-ACK codebook is generated on the basis of a slot corresponding to a value of an HARQ-ACK feedback timing parameter (K1) set in a sub-slot level, and each of bits configuring the HARQ-ACK codebook corresponds to at least one sub-slot form among a plurality of sub-slots included in the slot.

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.
