Unmanned aerial vehicles (UAVs) fulfill the high reliability and availability requirements of next generation cellular networks. In this paper, one relaying UAV receives information from one base station (BS) to serve the target ground node (GN). We investigate an energy-efficiency based UAV 3D trajectory optimization, by joint considering communication throughput and the UAVs energy consumption. We adopt sequential convex optimization and iterative method to tackle the nonconvex optimization problem. Finally, numerical results verify the supremacy of proposed algorithm.
