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.
