Bi-directional Power and Trajectory Control for UAV-assisted Cellular Systems
2021 International Conference on Information and Communication Technology Convergence (ICTC)（2021）
摘要
In this paper, we aim to maximize the total uplink and downlink sum-rate by optimizing the trajectory of UAV used as relay base station in an OFDM-based UAV-assisted cellular system. We propose a bi-directional power allocation and trajectory control problem to maximize the total rate with collision avoidance, altitude limitations, and mobility constraints on UAVs. Trajectory control dependent on ...
