摘要: 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).

摘要: Provided is a packet processing apparatus and method for audio/video (AV) data transmission, in which a simple protocol optimized for AV data transmission is used. Information distinguishing a data packet from a control packet may be included in a data link layer packet header, so that a data packet and a control packet may be distinguished from each other and thereby may be processed according to different procedures.

摘要: Provided are a method and apparatus for generating a data frame. The method includes generating subframes from at least one media access control (MAC) service data unit (MSDU); generating a retransmission policy field for recording a policy related to a retransmission request, against an error occurring while the subframes are being transmitted, with regard to each of the subframes; and generating the data frame by using the subframes and the retransmission policy field which is generated with regard to each of the subframes.
