摘要： Wireless communication between a first transmitter and a first receiver for a new transmission is established on the same wireless data channel used for ongoing transmission between a second transmitter and a second receiver. This is achieved by determining if the second receiver can receive signals from the first transmitter, and determining if the first receiver can receive signals from the second transmitter. If the second receiver cannot receive signals from the first transmitter, and the first receiver cannot receive signals from the second transmitter, then a new transmission is performed from the first transmitter to the first receiver by spatial reuse of the wireless data channel at least partially concurrently with said ongoing transmission on said data channel.

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： Reducing latencies for content protection in audio/video networks includes reserving a wireless channel for a time period to accommodate control message exchange for content protection in data communication between a wireless transmitter and wireless receiver over a wireless channel. The control message exchange includes wirelessly transmitting a control request message from the transmitter for content protection to the receiver, and transmitting a control response message from the receiver to the transmitter in reply. Reserving the wireless channel includes reserving the wireless channel for a time period that accommodates the control message exchange. The time period includes a single transmission opportunity period for communication on the wireless channel, to reduce latency for the control message exchange between the transmitter and receiver.
