Joint Trajectory Design and BS Association for Cellular-Connected UAV: An Imitation-Augmented Deep Reinforcement Learning Approach

This article concerns the problem of the trajectory design and base station (BS) association for cellular-connected unmanned aerial vehicles (UAVs). To support safety-critical functions, one primary requirement for UAVs is to maintain reliable cellular connectivity at every time instant during the f...
