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.
