摘要:
A system and a method for service gap identification is disclosed. The method comprises retrieving data on a network coverage area, dividing the network coverage area into a plurality of data sets, determining a first number of data sets of the plurality of data sets having a first number of poor coverage samples based on the retrieved data, and generating a service gap polygon based on the determined number of data sets having the first number of poor coverage samples.

Aspects described herein relate to a base station for providing air-to-ground wireless communication over various altitudes. The base station includes a first antenna array comprising one or more antennas configured to form a first cell coverage area extending substantially from a horizon up to a first elevation angle away from the first antenna array to a predetermined distance from the first antenna array. The base station further includes a second antenna array configured at an uptilt elevation angle to form a second cell coverage area extending at least from the first elevation angle to a second elevation away from the second antenna array, wherein the first cell coverage area and the second cell coverage area are concentric to define the ATG cell at least to the predetermined distance and up to a predetermined elevation.

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.
