Channel access method for very high throughput (vht) wireless local access network system and station supporting the channel access method

Abstract

A method and a device for transmitting data in a wireless communication system are discussed. The method according to one embodiment includes receiving, by a first station, a first frame from a second station through at least one idle subchannel of a plurality of subchannels; and transmitting, by the first station, a second frame to the second station. If the first frame includes channel information related to all of the at least one idle subchannel through which the first frame is transmitted, the second frame is transmitted via the at least one idle subchannel indicated by the channel information. If the first frame does not include the channel information, the second frame is transmitted via at least one of a plurality of subchannels.

Dependencies are inferred from the claim text.
