Abstract: The present specification may provide a method for performing discovery by a seeker terminal in a wireless communication system. In this instance, the method by which a seeker terminal performs discovery may comprise the steps of: transmitting a first frame associated with discovery, by the seeker terminal, to an advertiser terminal; receiving, from the advertiser terminal, a second frame in response to the first frame; and discovering a matching P2P terminal on the basis of the received second frame. The seeker terminal may transmit the first fame by operating in only a search mode, without a listen mode and a scan mode; the advertiser terminal may transmit the second frame by operating in only a listen mode: and the seeker terminal and the advertiser terminal may perform discovery in only a first channel.

Abstract: The present document relates to a backoff procedure and apparatus for efficiently accessing a broadband channel in a wireless LAN system. To this end, a station performs a clear channel assessment (CCA) operation in each of a plurality of channels, and when one or more of the plurality of channels is/are not used and the one or more channels is/are not used for frame transmission in the basic service set (BSS) of its/their station, the station is characterized in that it performs or re-performs a backoff procedure in the one or more channels. When a backoff counter value becomes zero according to the backoff procedure, the station may transmit a frame through the one or more channels.
