Joint optimization on UAV communication system assisted by BIOS
As an important member of the reconfigurable intelligent reflector,intelligent full-surface has attracted more and more attention because of its ability to serve both sides of the metasurface.In order to solve the problem that the unmanned aerial vehicle(UAV)and ground user equipment are blocked by obstacles in urban scenes,a BIOS-based joint optimization of UAV communication system is studied.The goal is to maxi-mize the sum rate of all users through the two phase shift design of the joint BIOS and the UAV flight trajectory design.Although it is difficult to solve the optimal solution due to its non-convexity,in order to solve this problem,an efficient algorithm is proposed to obtain high-quality sub-optimal solutions.The simulation results show that compared with the traditional intelligent reflector assisted UAV communication,the BIOS can signifi-cantly improve the user equipment and speed.
