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: In the present specification, a method may be provided in which a NAN terminal exchanges frames in a wireless communication system. Here, the method in which a NAN terminal exchanges frames may include the steps of: transmitting a first frame, in which a first NAN terminal requests first properties information, to a second NAN terminal, and receiving a second frame for the first properties information from the second NAN terminal. Here, when the first frame is a service discovery frame, the first properties information may be set on the basis of a first field value of the first frame, and when the first frame is a GAS frame, the first properties information may be set as proxy service information.

Abstract: Provided are a method and apparatus for acquiring information of a CHIP device using a GAS in a wireless LAN system in a smart home environment Specifically, a controller obtains first to third identifiers by scanning a quick response (QR) code of a controlee; The controller transmits a GAS initiation request message to the controlee. The controller receives a GAS initiation response message from the controlee. The GAS initiation request message includes first and second identifiers and an encrypted payload. The GAS initiation response message includes a decrypted payload when the first and second identifiers are the same as identifiers of the controlee.
