    Abstract: A method and a device for positioning a NAN terminal in a wireless LAN system are provided. A first station receives, through a service discovery frame during a preset discovery window, allocation information of an available window for reporting a location estimate value of the first station, location information of a second station located within a distance of one hop from the first station, and location information of a third station located within a distance of at least one hop from the second station. The first station determines the location estimate value of the first station on the basis of the location information of the second station and the location information of the third station. The first station reports the location estimate value of the first station during a section indicated by the allocation information of the available window.

    Abstract: In the present specification, provided is a method for relaying, by a NAN proxy server, data communication in a wireless communication system. Here, the method for relaying data communication by an NAN proxy server may comprise the steps of: transmitting server capability attribute information of the NAN proxy server to a first NAN proxy client; receiving connection capability attribute information from the first NAN proxy client; transmitting proxy relay request attribute information to the first NAN proxy client; receiving proxy relay response attribute information from the first NAN proxy client; and performing scheduling for the first NAN proxy client and relaying data communication to the first NAN client. Here, the proxy relay request attribute information may be transmitted if information on a direct connection failure is included in the connection capability attribute information.
