Trajectory Optimization for Autonomous Flying Base Station via Reinforcement Learning
International Workshop on Signal Processing Advances in Wireless Communications, 2018In this work, we study the optimal trajectory of an unmanned aerial vehicle (UAV) acting as a base station (BS) to serve multiple users. Considering multiple flying epochs, we leverage the tools of reinforcement learning (RL) with the UAV acting as an ...
