- W2902552783 abstract "Abstract In areas without infrastructure coverage, unmanned aerial vehicles (UAVs) have made great progress in wireless communication because of its low cost and flexible connectivity. This paper studies a novel mobile relay system, which can obtain the properties of high-mobility and high-performance by adopting an UAV as a relay node. By assuming that the UAV employs full-duplex (FD) and spectrum-efficient trajectory-based decode-and-forward (DF) relay, we study the throughput maximization problem by jointly optimizing UAV trajectory and source/relay transmission power, subject to the constraints on initial/final location, maximum speed and maximum power of the UAV and information-causality of each node in practical situations. It is revealed that there exists a jointly optimal allocation of trajectory and power for the UAV achieved by alternative and iterative algorithm. Numerical results show that by jointly optimizing the trajectory and power, the proposed two UAV-enabled full-duplex relay models are able to obtain significant throughput gains over the conventional static relay." @default.
