Claim 6:
7. A first station of a wireless communication system, the first station comprising:
a wireless communication module; and
a processor configured to:
receive, from a second station, a grant that schedules a second transmission to the second station in at least one subframe through an unlicensed cell,
determine a channel access type for performing the second transmission among a first type channel access and a second type channel access according to a predetermined interval determined based on a first transmission through the unlicensed cell from the second station, and
perform, through the wireless communication module, the second transmission using the determined channel access type, wherein the first type channel access is based on a channel sensing with a random backoff using a CW (contention window) of variable size before data transmission, wherein the second type channel access is based on a channel sensing with a single interval before data transmission,
wherein the processor is configured to perform the second transmission using the second type channel access when all of the second transmission is included in the predetermined interval.
