摘要： The present specification relates to a method for transmitting data by a first neighbor awareness networking (NAN) device in a wireless communication system. The method for transmitting data may comprise the steps of: performing a service discovery for a first service with a second NAN device through a service discovery frame (SDF); and exchanging data for the first service with the second NAN device on the basis of the performed service discovery. Here, when at least one of authentication and association is required in transmitting the data for the first service, attribute information which is required for the data transmission among information on authentication attributes and information on association attributes may be included in the service discovery frame.

摘要： 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.

摘要： The present specification suggests a signal processing method for changing an operating mode to configure a PPDU in a wireless local area network (WLAN) system. Specifically, a first station receives indication information indicating a change in operating mode that indicates a number of spatial streams and a receiving channel bandwidth that are supported by a second station from the second station. The first station transmits a block acknowledgement (BA) in response to the indication information, the BA including a first delay required bit. The first station defers applying the indication information so that the indication information is not applied when the first delay required bit is a predetermined value.

摘要： Provided according to the present invention is a method for a first neighbor awareness networking (NAN) device for performing service discovery in a wireless communication system. A method for performing service discovery comprises the steps of: exchanging a subscribe message with a second NAN device; and transmitting a first service discovery frame (SDF) on the basis of the exchanged subscribe message. The first service discover frame comprises a NAN connection capability attribute field, wherein the NAN connection capability attribute field comprises a first type interface information field, wherein the first type interface information field can show whether or not the first NAN device supports a first type interface.

摘要： 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.
