Abstract: A method and a device for transmitting data in a neighbor awareness network (NAN) are provided. A NAN device acquires a NAN association identifier (AID) from a unique identifier and receives a traffic indication map (TIM) information on the basis of a TIM offset. TIME offset is determined on the basis of the NAN AID.

Abstract: According to an embodiment of the present specification, a method for transmitting an uplink frame in a wireless local area network (WLAN) system and performed by a user station (STA) includes: receiving from an access point (AP) a trigger frame comprising association identifier information for orthogonal frequency division multiple access (OFDMA)-based random access and allocation information indicating a resource unit, wherein the association identifier information indicates any one of a first value irrelevant to whether being associated with the AP, a second value for a first STA group associated with the AP, and a third value for a second STA group un-associated with the AP; and performing a countdown operation according to the association identifier information based on a backoff value which is set in a backoff counter of the user STA in order to transmit the uplink frame.

Abstract: Proposed is a method for receiving a Wi-Fi service by a wireless LAN station supporting an application service platform (ASP). Specifically, the Wi-Fi service can be received through at least two connection techniques, for example, a Wi-Fi direct connection of Wi-Fi infrastructure connection may be used. The wireless LAN station having an ASP may detect information on each of the connection techniques and may be provided with the Wi-Fi service using one of the connection techniques. In addition, when a change in a communication environment or the like occurs, the connection technique may be switched and, in this case, signaling for switching the connection technique may be used.

Abstract: The present specification relates to a method for a NAN proxy client to perform registration to a NAN proxy server in a wireless communication system. The method for a NAN proxy client to perform registration to a NAN proxy server may comprising: transmitting a subscribe message regarding proxy service search to the NAN proxy server; receiving a publish message from the NAN proxy server; transmitting a proxy registration request message to the NAN proxy server on the basis of proxy service; and receiving a proxy registration response message on the basis of the proxy registration request message.

Abstract: The present invention relates to a method for a NAN proxy client transitioning a state in a wireless communication system. Here, the method for a NAN proxy client transitioning a state may comprise the steps of: the NAN proxy client transitioning, to a NAN proxy server, a request message requesting the escrowing of a proxy service; receiving a response message from the NAN proxy server; performing registration to the NAN proxy server on the basis of the response message; and the state of the NAN proxy client transitioning. Here, if the registration to the NAN proxy server is performed, the state of the NAN proxy client can be transitioned to a first state.

Abstract: A method and apparatus for outputting a supplementary content in a WFD is disclosed. A method for outputting a supplementary content in a WFD may comprise the steps of: after a WFD source is connected to a WFD, transmitting, by the WFD source, an RTSP-based RTSP parameter request message to a WFD sink in order to perform a capability negotiation procedure with the WFD sink; transmitting, by the WFD source, an RTSP parameter response message to the WFD sink in response to the RTSP parameter request message; and after the capability negotiation procedure is performed, transmitting, by the WFD source, a transmission stream, obtained by overlapping and multiplexing a video stream including video data having first resolution and a supplementary stream including supplementary data having second resolution, to the WFD sink, wherein a WFD discovery response frame may include second resolution-related information for determining the second resolution and an RTSP parameter response frame may include the second resolution-related information.
