Communication method, device, unmanned aerial vehicle and system for coordinated transmission of information and energy

Abstract

The invention provides a communication method, device and system for information and energy cooperative transmission, an unmanned aerial vehicle, and an unmanned aerial vehicle. The communication method for information and energy cooperative transmission comprises the following steps: initializing power distribution and a flight path of the unmanned aerial vehicle and a first cooperative throughput between a source point transmitter and a terminal point receiver, and then optimizing and calculating optimal decision distribution, optimal power distribution and optimal flight path of the unmanned aerial vehicle according to the power distribution, the flight path and the first cooperative throughput, and finally carrying out cooperative communication according to the optimal decision distribution, the optimal power distribution and the optimal flight path. According to the communication method for information and energy cooperative transmission, wireless energy-carrying communication isintroduced into unmanned aerial vehicle auxiliary communication, so that energy limitation of the unmanned aerial vehicle can be effectively relieved by obtaining wireless energy from a radio signal transmitted by an information source point, and the cooperative throughput between a source point transmitter and a terminal point receiver is maximized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a communication method, device, unmanned aerial vehicle and system for coordinated transmission of information and energy. Background technique [0002] In order to enhance network coverage and meet the growing demand for data traffic, the deployment of wireless networks has shifted from traditional 2D planes to 3D spaces. According to this trend, UAV (Unmanned Aerial Vehicle, referred to as UAV) assisted wireless communication has attracted great attention from the industry and academia. Due to its low cost, high mobility and deployment flexibility characteristics, drones hovering in the air are more likely to establish wireless links with better channel conditions (e.g., line-of-sight ), so UAV-assisted communication is considered to better support wireless communication in many practical applications, such as public safety and disaster management.
