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: 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: 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 for performing 60 GHz WFD (Wi-Fi Display) connection by a first terminal in a wireless communication system is disclosed. The method includes transmitting, by the first terminal, a message requesting 60 GHz WFD connection to a second terminal through an access point (AP); and receiving a message accepting 60 GHz WFD connection from the second terminal through the access point (AP). The 60 GHz WFD connection request message includes capability information indicating whether the first terminal supports 60 GHz. The 60 GHz WFD connection accept message includes capability information indicating whether the second terminal supports operation at 60 GHz. The messages are exchanged with each other on the basis of at least one of 2.4 GHz and 5 GHz.
