Abstract:
A method for gaining access according to one embodiment of the present invention in which a station (STA) gains access to a medium in wireless communication system comprises the steps of: sensing a carrier wave for a medium so as to transmit a set frame; and, if the medium is busy, executing a random back-off procedure, wherein the starting point of the random back-off procedure is indicated by a second parameter randomly selected from within a range in accordance with a first parameter.
