摘要： Methods and apparatuses are described herein for adapting clear channel assessment (CCA) thresholds with or without Transmit Power Control (TPC) are disclosed. An IEEE 802.11 station (STA) may dynamically calculate a STA specific transmit power control (TPC) value and a STA specific clear channel assessment (CCA) value based on a target TPC parameter and a target CCA parameter. The target TPC parameter and the target CCA parameter may be received from an IEEE 802.11 cluster head configured to control TPC and CCA for a plurality of STAs associated with the BSS. The target TPC parameter and the target CCA parameter also may be related. The STA may then determine whether a carrier sense multiple access (CSMA) wireless medium of a wireless local area network (WLAN) basic service set (BSS) is occupied or idle based on the STA specific CCA value.

摘要： Methods and apparatus are presented for WiFi sectorization and beamforming. In one embodiment, an access point (AP) may send a Request to Send (RTS) to a first station (STA), receive a Sectorized Coordinated Beam (CB/S)-Clear to Send (CTS) from the first STA, and receive a CBS-CTS from a second STA. The AP may then send a Null Data Packet (NDP) Announcement (NDPA), followed by a NDP. The NDP may be sent using sub-sector beamforming. The AP may receive feedback from the first STA, and may create a targeted beam to transmit data to the first STA. The AP may determine sector order and timing based on the feedback. The AP may also identify whether the STA is a sector-edge STA or non-sector-edge (or sector center) STA. The AP may allow the STA to transmit based on whether the STA is assigned to the sector-edge or non-sector edge group.

摘要： 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.
