摘要/Abstract

摘要： With the advantages of low cost and high mobility, unmanned aerial vehicles (UAVs) have played an important

role in wireless communication. We investigate a UAV-enabled mobile relaying system, where a UAV is used as a

mobile relay to assist in the communication from a ground source to a ground destination since their direct link is

blocked. Unlike the conventional mobile relay in which the UAV adopts straight line or circular trajectory, we

consider a more general elliptical trajectory and use realistic channel models. By assuming that the UAV employs

time-division duplexing (TDD) based decode-and-forward (DF) relaying, we jointly optimize the time allocations

and the UAV trajectory to formulate the maximization of spectrum efficiency (SE). The simulation results show that

the trajectory we designed achieves a higher SE than the optimal circular trajectory and static relaying.
