METHODS AND PROCEDURES FOR SCHEDULING TO SECTOR-EDGE AND NON-SECTOR-EDGE STATION GROUPS |
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. |
