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.
