UAV-RIS Trajectory Optimization Algorithm for Energy Efficiency in UAV-RIS Based Non-Terrestrial Systems
This paper propose UAV-RIS communication that takes Energy Efficiency (EE) into account in non-terrestrial networks through trajectory optimization of UAV-RIS that jointly considers communication throughput and energy consumption of unmanned aerial vehicles (UAVs). The proposed algorithm optimizes the UAV-RIS trajectory, base station beamforming vector, and RIS beamforming vector by appropriately using Successive Convex Approximation (SCA), Karush-Kuhn-Tucker (KKT) conditions.
