Abstract: A method is provided for a first terminal performing connection capability exchange in a wireless communication system. The method includes transmitting, to a second terminal, a P2P probe request frame for a service discovery, receiving, from the second terminal, a P2P probe response frame for the service discovery, establishing of a connection with the second terminal and forming an ASP session with the second terminal. The P2P probe request frame and the P2P probe response frame include connection capability exchange information and establishing the connection is performed based on the connection capability exchange information.

Abstract: Provided are a method and an apparatus for transmitting metadata in a WFD. More particularly, a WFD source transmits, to a WFD sink, a first transmission stream in which an audio stream and a video stream are superimposed and multiplexed. The WFD source receives, from the WFD sink, a first RTSP request message for requesting transmission of metadata for audio data and video data during the transmission of the first transmission stream. The WFD source transmits, to the WFD sink, a first RTSP response message in response to the first RTSP request message during the transmission of the first transmission stream. The WFD source transmits, to the WFD sink, a metadata stream including the metadata and a second transmission stream in which the audio stream and the video stream are superimposed and multiplexed.

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.
