CONCENTRIC CELLS IN A WIRELESS COMMUNICATION SYSTEM

摘要

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.

1. A base station for providing air-to-ground (ATG) wireless communication over various altitudes of an ATG cell, the base station comprising:
a first antenna array comprising one or more antennas configured to form a first cell coverage area extending substantially from the horizon up to a first elevation angle away from the first antenna array to a predetermined elevation relative to the first antenna array along each of a plurality of directions from the base station; a second antenna array configured at an uptilt elevation angle to form a second cell coverage area extending away from the second antenna array at least from the first elevation angle to a second elevation angle, wherein the first cell coverage area and the second cell coverage area are concentric to combine to define the ATG cell to provide continuous coverage within the ATG cell having a substantially cylindrical shape up to the predetermined elevation and out to a radial distance defined at an intersection of the first elevation angle with the predetermined elevation.
