摘要：
Unmanned aerial vehicle (UAV) communication is a promising technology to yield great benefits for 5G wireless networks and beyond. In this paper, we investigate the downlink transmission in wireless backhaul networks when a UAV is deployed as the flying base station. A joint optimization problem of UAV's placement, spectrum allocation, and power control is formulated, which is an NP-hard problem. To solve the above-mentioned problem efficiently, we propose decomposing the underlying problem into two subproblems, which are then solved alternatively in an iterative manner. Simulation results under various settings are provided to demonstrate the performance improvement of the proposed algorithm over baseline schemes. © 2019 IEEE.
