摘要:
A method and device for discovering a WiFi display service in a Wi-Fi direct (WFD) network, the method includes: generating a service discovery request frame for discovering a service supported by a second WFD device in the WFD network; transmitting the service discovery request frame to the second WFD device; and receiving a service discovery response frame from the second WFD device in response to the service discovery request frame, wherein the service discovery request frame and the service discovery response frame are generated by using a generic advertising service (GAS) initial request frame of 802.11u and a GAS initial response frame of 802.11u, respectively.

A method and an apparatus for service discovery in a Wi-Fi direct (WFD). The method includes: generating by a first WFD device a service discovery request frame for discovering whether a service is supported by a second WFD device in the WFD network; transmitting the generated service discovery request frame from the first WFD device to the second WFD device; and receiving at the first WFD device a service discovery response frame from the second WFD device in response to the transmitted service discovery request frame, wherein the service discovery request frame and the service discovery response frame are generated by using a Wi-Fi protected setup (WPS) information element (IE).

A method of performing communication between a sink device and a source device in a Wi-Fi direct network is provided. The method includes receiving a user's input, on a sink device, for controlling audio/video (AV) data received from the source device, generating a message for controlling the AV data based on the user's input, and transmitting the message to the source device through a Wi-Fi direct link.

Provided are a method and apparatus for supporting a multiband wireless fidelity (WiFi). The method for supporting the multiband WIFI includes: assigning a category and a frequency band for traffic, based on one or more characteristics of the traffic; packetizing the traffic in a media access control (MAC) unit corresponding to the assigned frequency band; and transmitting the packetized traffic by using the assigned frequency band in a physical layer (PHY) unit corresponding to the assigned frequency band.
摘要:
A method of performing communication between a first device and a second device by using a Wi-Fi direct scheme is provided. The method may include receiving, by the first device, information on relating to a content protection capability of the second device in during a device discovery procedure; and determining, by the first device, whether to perform a connection setup procedure with the second device based on the received information on relating to the content protection capability of the second device.

摘要:
A method and apparatus for group owner (GO) renegotiation are provided. For example, the method and apparatus may be used for GO renegotiation in a wireless personal network (WPAN), for example, a 60-gigahertz (60 GHz) peer-to-peer (P2P) wireless network. The incumbent group owner (e.g., personal base station set (PBSS) control point (PCP)) controls the operation of the group. GO renegotiation can occur, for example, when a newly arriving device (e.g., a prospective group owner) is trying to connect to the PBSS and/or, for example, with PCP rearrangement among members of an existing group. As an example, after the formation of the group, the PCP may want to relinquish the role of being the PCP. A procedure is described for deciding among clients and the PCP which device will assume the role of group owner from the existing PCP in the event the role of group owner is to be reassigned.

Provided are a method and an apparatus for transmitting a packet in a wireless local area network (LAN), the method including determining whether a packet, which does not expire during the current transmission opportunity (TXOP) but will expire before a next TXOP is secured, exists or not based on a time-to-live (TTL) of the packet; if it is determined that the packet does not expire during an expansion of the current TXOP, expanding the current TXOP; and transmitting the packet to a receiving station.
