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.

摘要： A method and system for transmitting video information from a sender to a receiver over a wireless channel is provided. Video information bits are placed into one or more data packets at the sender, and each data packet is transmitted from the sender to the receiver over a wireless channel during a current time frame. For each transmitted data packet, the sender receives a corresponding acknowledgment packet from the receiver. The sender then performs burst retransmission of the negatively acknowledged packets during a next time frame comprising a BeamTrack Group for transmission of further data packets from the sender to the receiver over a wireless channel. The receiver utilizes each retransmitted data packet to recover a lost or erroneously received data packet.

摘要： A method and a system for bit reorganization and packetization of uncompressed video for transmission over wireless communication channels. The bit stream of the uncompressed video is reorganized according to importance levels of video bits. Then, various unequal protection methods such as encoding are applied to bits at different video importance levels. The reorganized and encoded information is then transmitted from a transmitter to a receiver over a wireless channel. The receiver performs the reverse steps of the transmitter, along with error detection/correction as needed, to recover the uncompressed video information.

摘要： A system and method for discovering and tracking communication directions is disclosed herein. In one embodiment, communication directions for two devices with asymmetric antenna systems are discovered. In one embodiment, a contention access period (CAP) is partitioned into an association CAP and a regular CAP, either of which may be further partitioned into sub-CAPs corresponding to different reception directions. In one embodiment, an association request command is transmitted by a device at different association sub-CAPs to train a transmission direction of the device. In one embodiment, further training is performed to find the best communication directions, as collisions may occur when association request commands are transmitted at different association sub-CAPs.
