WIPO Patent Application WO/2013/115629
Kind Code:
A1
Abstract:
The present invention relates to a wireless communication system, and more specifically to a method and an apparatus for channel access via a null data packet frame in a wireless LAN system. A method for channel access from a station (STA) in a wireless communication system according to one embodiment of the present invention comprises the steps of: receiving, from an access point (AP), configuration information for one or more slots for channel access; receiving a first frame, from the AP, from a particular slot from among the one or more slots; and starting channel access after receiving the first frame, wherein the first frame can be a null data packet (NDP) frame.
