    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: Disclosed are a method, an apparatus, and a system for performing channel access. In detail, provided are a method including: receiving uplink scheduling information; and when the user equipment has stopped an uplink transmission during the uplink transmission being performed according to the uplink scheduling information, to resume the uplink transmission, performing a second type channel access when a channel sensed by the user equipment is continuously idle after the uplink transmission has been stopped, and performing a first type channel access when the channel sensed by the user equipment is not continuously idle after the uplink transmission has been stopped, wherein the first type channel access comprises performing a random backoff after a channel sensing, and the second type channel access only comprises performing a channel sensing and an apparatus and a system therefor.

    Abstract: Provided is a wireless communication user equipment that wirelessly communicates. The wireless communication user equipment includes a communication module; and a processor configured to control the communication module. The processor is configured to receive a demodulation reference signal (DM-RS) of data channel and receive the data channel based on the DM-RS of the data channel, wherein a time-frequency resource mapped to the DM-RS is predetermined. When the time-frequency resource mapped to the transmission of the DM-RS of the data channel overlaps with the time-frequency resource mapped to a different purpose from the transmission of the DM-RS, the processor is configured not to receive the DM-RS in a resource element (RE) overlapping with the time-frequency resource mapped to the different purpose in the time-frequency resource mapped to the transmission of the DM-RS. The DM-RS is a reference signal specific to the wireless communication device.

    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.
