  • Patent number: 10362586
    Abstract: A method for channel reservation and communication using carrier sense multiple access (CSMA) with directional antennas in a wireless network. A source station (STA) may transmit a directional request to send (RTS) frame to a destination station before a data transmission. Upon receipt of the RTS frame, the destination STA may transmit a transmit network allocation vector (TNAV) frame instructing receiving stations not to perform transmissions toward the destination STA for a predefined period of time, which may include a channel quality measurement (CQM) period. The destination STA may transmit a directional clear-to-send (CTS) frame when channel quality estimated during the CQM meets a criterion. The source STA may then transmit a directional data transmission to the destination STA upon receipt of the CTS frame.
