Abstract: A method for performing an uplink transmission to a base station by a user equipment through an unlicensed cell in a wireless communication system is provided. The method includes: receiving an uplink grant that schedules the uplink transmission in at least one subframe from the base station; and performing the uplink transmission in the at least one subframe using at least one of a first type channel access or a second type channel access. The uplink transmission is performed using the second type channel access when all of the at least one subframe is included in a predetermined interval determined based on a downlink transmission through the unlicensed cell from the base station.

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: 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.
