    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.

    Abstract: A method and a device for transmitting metadata in a WFD are provided. Particularly, a WFD source forms a WFD frame including a WFD header and metadata. The WFD source transmits, to a WFD sink, a packet stream created by packetizing a metadata stream including the WFD frame. The WFD header includes a metadata structure field and a metadata update indicator. The metadata structure field indicates whether the metadata has a video metadata structure or an audio metadata structure. The metadata update indicator indicates that previous metadata is updated such that all of the previous metadata is replaced with new metadata, or that the previous metadata is incrementally updated together with updated metadata.

    Abstract: The present specification may provide a method for performing data exchange by NAN terminal in a wireless communication system. In this instance, the method in which the NAN terminal performs data exchange may comprises the steps of: discovering a first service by a first NAN terminal using at least one of a publish message and a subscribe message; transmitting a data request message associated with the discovered first service to a second NAN terminal by the first NAN terminal; receiving a data response message from the second NAN terminal by the first NAN terminal; and performing data exchange relating to the first service with the second NAN terminal by the first NAN terminal. In this case, the data request message may be transmitted on the basis of a data request method called by the first NAN terminal, and service protocol type information and port number information, which are returned as a return value, may be included in the data request message and may be transmitted on the basis of the data request method.

    Abstract: A method for a neighbor aware network (NAN) according to one embodiment of the present specification comprises the steps of: allowing a first terminal to exchange device capability information regarding a scheduling scheme for data communication with a second terminal in a search window; allowing the first terminal to maintain an awake state in a paging window to receive a paging message including identification information indicating a receiving terminal (recipient) for traffic to be received from the second terminal, when a paging scheme is selected by means of the scheduling scheme; and allowing the first terminal to terminate, early, the paging window and switching from the awake state to a sleep state, when a channel evaluation indicator indicating a channel state of a wireless channel according to a signal received at a physical layer of the first terminal is idling for a predetermined threshold time.

    Abstract: A method and an apparatus for switching an input character in a WFD are disclosed. The method for switching an input character in a WFD comprises the steps of: transmitting, by a first WFD device, a character switch capability parameter to a second WFD device through a UIBC capability negotiation process with the second WFD device; transmitting, by the first WFD device, a first character switch establishment parameter to the second WFD device through a UIBC capability UIBC establishment process so as to establish the first character outputted onto each screen of the first WFD device and the second WFD device; transmitting, by the first WFD device, a key code for a character switch button through a UIBC to the second WFD device through a user input device of the first WFD device; and transmitting, by the first WFD device, a second character switch establishment parameter to the second WFD device through a UIBC re-establishment process so as to switch, to the second character, the first character outputted onto each screen of the first WFD device and the second WFD device.
