METHOD AND APPARATUS FOR PERFORMING CHANNEL ACCESS IN WIRELESS LAN SYSTEM

摘要

One embodiment of the present invention relates to a method whereby a multi user (MU) group station (STA) performs channel access in a wireless communication system, the method for performing channel access comprising the steps of: receiving a resource allocation frame; and checking a group indicator field comprised in the resource allocation frame, wherein the STA determines a slot start offset on the basis of a slot allocation field in case the group indicator field indicates the presence of the slot allocation field for an MU group in the resource allocation frame.
