Abstract
A method and an apparatus for accessing a channel in a wireless LAN. A method for a station (STA) accessing a channel may comprise: a step of the STA receiving an access distribution element through a passive scanning frame; the STA selecting an access random variable based on the access distribution element; a step of the STA determining a minimum value of a passive scanning-specific competition window based on the access random variable; and the STA accessing the channel based on a back off time that is determined based on the passive scanning-specific competition window.
