Abstract

The invention discloses a laser energy supply unmanned aerial vehicle wireless communication method with multiple base stations and multiple laser emitters. Through joint optimization of the trajectory, the related speed, the transmission power and the transmission mode of the unmanned aerial vehicle, the minimum throughput of downlink communication between the unmanned aerial vehicle and each ground base station is maximized and the communication requirement of the system is met under the condition that a plurality of laser emitters and a plurality of base stations meet the laser energy constraint condition.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle communication, and more specifically relates to a wireless communication method for a laser-powered unmanned aerial vehicle with multiple base stations and multiple laser transmitters. Background technique [0002] As an auxiliary communication, drones are of great help in improving the ground wireless communication range and network capacity. Improving effective and reliable communication can promote the widespread application and popularization of drones. However, short battery life is a common problem with drones. Without sufficient endurance, it means that the execution of tasks will be greatly restricted, and the maximum advantage cannot be exerted. In order to solve this problem, it is proposed in the prior art to use a laser to charge the UAV while the UAV communicates with the downlink base station. The UAV does not need to return to the base station or a charging station...
