摘要： A system and method for efficiently communicating messages over a low-rate channel between multiple devices in a system for wireless communication of uncompressed video is disclosed. The method includes various control bits in a beacon control field of a beacon frame to improve the efficiency of the beacon processing, thereby reducing beacon processing time and size of the beacon frame itself. The transmitting device can use one or more of the various control bits to indicate whether there are changes in various MAC payload information fields. The receiving station can use one or more of the control bits to eliminate the need to parse one or more MAC payload information fields whose values have not changed from the previous beacon frame.

Pixels in an uncompressed video frame are grouped into groups of pixels for wireless transmission from a transmitter to a receiver, wherein the neighboring pixels in each group possess (have) high spatial correlation. Upon receiving the pixel groups, the receiving station reconstructs the video frame from the received pixel groups, wherein upon detecting an erroneous pixel in a group, information from one or more neighboring pixels in that pixel group are used in place of the erroneous pixel. Further, FEC encoding is utilized recovering bit-errors.

摘要： A method and system for device discovery in a wireless network is provided. The device discovery involves directionally transmitting a data unit from a transmitting station over a channel in different directions to emulate omni-directional transmission, receiving the data unit transmissions from different directions at a receiving station, determining the quality of the transmissions received from the different directions, and detecting location information for the transmitting station relative to the receiving station based on the highest quality transmission among the transmissions received from the different directions. Further, if a channel has sufficient bandwidth to satisfy direct link communication between two stations, then during a direct link set-up stage, the two stations conduct a probing message exchange using omni-direction transmission, and upon successful probing, obtain communication link status information and set proper communication configurations for the two stations based on the communication link status information.
