receiving, from a second station, a grant that schedules a second transmission to the second station in at least one subframe through an unlicensed cell;
determining 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, 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; and
performing the second transmission in the at least one subframe using the determined channel access type,
wherein the second transmission is performed using the second type channel access when all of the second transmission is included in the predetermined interval.
