Abstract
Systems and methods configured to form and manage different types of beams toward target ground terminals to “optimally” communicate with the terminals. In one set of embodiments, the UAV generates a set of beams to cover cells on the ground, the beams are divided into groups, and the UAV communications system deterministically and sequentially turns a subset of the beams on/off to reduce cross-beam interference and increase system throughput. In another embodiment, in order to increase throughput, the UAV communications system determines the highest data rate on the downlink and uplink that are decodable at the receiver given the received signal to interference plus noise ratio (SINR) while maintaining a low packet error rate. Systems and methods are described to determine the UAV antenna pattern toward different terminals needed for SINR calculation and data rate determination.
