More Information
Summary:A method and apparatus may be used to support coordinated and cooperative sectorized transmissions. Power control and clear channel assessment for sectorized transmissions may be used, along with sectorized beacon and associated procedures. Transmissions in a network may be protected by a first access point (AP) sending an omni-directional transmission and a beamformed or sectorized transmission to a station (STA), an overlapping basic service set (OBSS) confirming a spatially orthogonal (SO) condition based on the omni-directional transmission, and a second AP monitoring the omni-directional transmission and confirming the SO condition. The STA may be configured to receive a request-to-send (RTS) frame indicating data is available for transmission, and transmit a cooperative sectorized (CS) clear-to-send (CTS) frame indicating an ability for multiple AP reception.
