基于能量收集的IRS-UAV无线传输方案OA

Aiming at the optimization of information transmission rate and energy consumption of intelligent reflecting sur-face(IRS)combined unmanned aerial vehicle(UAV)-assisted wireless communication system,an innovative IRS-UAV wireless relay transmission scheme is proposed.The solution combines energy harvesting and time-switching technologies designed to maximize the system's information transfer rate through energy harvesting supported by the IRS-UAV.In this scheme,IRS-UAV first collects the energy emitted by the base station to maintain its own opera-tion,then reflects the energy of the base station to the user,and finally the user uses the collected energy to upload information.This combination of energy harvesting and relay transmission offers significant advantages in improving system performance.For the highly coupled non-convex optimization problems such as resource allocation,phase shift matrix and IRS-UAV position,the block coordinate descending method is used to solve the problem,which ef-fectively reduces the complexity of the problem.
