摘要： A system and method of reserving bandwidth for disjoint time intervals in a wireless network. Parameters for a disjoint network allocation vector (NAV) define a reservation of a plurality of disjoint time durations during which transmissions by devices other than a target device are deferred. Parameters are sent as a control or data packet over a network and received by the devices associated with the network.

摘要： A system and method for wireless communication over multi-rate channels are disclosed. One embodiment of the system includes source and destination devices that use first and second channels under a contention-based protocol. The first channel is directional with a first frequency and a first range. The second channel is omni-directional with a second frequency and a second range. The second frequency is lower than the first frequency, and the second range is greater than the first range. The source device may send the destination device a request for data transmission via the first channel over the second channel. The destination device may send the source device an approval for the data transmission over the second channel. The source device may further transmit an acknowledgment (ACK) of the approval over the second channel upon receiving the approval to prevent other devices in the system from contending for data transmission.

摘要： The present invention provides a method and a system for device discovery in wireless communication. One implementation involves scanning one or more wireless channels to discover a partner wireless station for a new transmission, by detecting peak energy and beacons on each scanned channel. If a beacon is not detected, then selecting the clearest channel among the scanned channels, and transmitting beacons on the clearest channel. Upon detecting a beacon from a partner station, establishing association with the partner station and selecting a wireless data channel for communication with the partner station. Another implementation involves discovering a partner wireless station to establish a data channel for communication with a discovering station that is associated with a coordinator station, and transmitting a bandwidth reservation request to the coordinator to reserve channel time for control message exchange between the discovering station and the partner station.

摘要： A system and method for wireless communication of uncompressed video data includes concealing corrupted portions of video data. Video packets received are transmitted over a wireless channel. Each of the video packets includes data blocks forming video data representing at least part of a video frame. Each of the data blocks is encoded with an error correction code. A data block determined to be corrupted is replaced with an uncorrupted data block selected from the data blocks in the video packets. The corrupted data block includes a first displayable element on the video frame and the uncorrupted data block includes a second displayable element on the video frame. The uncorrupted data block is selected at least partially based on proximity between the first and second displayable elements on the video frame.

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.
