Abstract: 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.

Abstract: A STA may comprise a receiver configured to receive, from an AP, a first polling frame addressed to a broadcast address and sent to a plurality of STAs. The first polling frame may indicate a plurality of sub-channels. The STA may further comprise a transmitter configured to transmit, to the AP, a first PPDU indicating SNR information, on one or more sub-channels of the plurality of sub-channels, a SIFS after the first polling frame is received. The transmitter may be configured to transmit the first PPDU while a second PPDU is transmitted to the AP by another STA of the plurality of STAs, wherein the second PPDU is transmitted on one or more other sub-channels of the plurality of sub-channels.
