A Novel Approach for UAV-Aided Vehicle-to-Everything Networks

Vehicle-to-everything (V2X) communications has been a promising solution under the demand of massive connectivity in vehicular devices. However, the mobility of vehicle is still challenging with the pressure on a higher throughput demand. Unmanned aerial vehicle (UAV) with a capability of flexible movement has been investigated to support the V2X networks. This paper proposes a novel system where a UAV can assist V2X communication under the realistic channel model of aerial devices. Furthermore, we derive a design problem for spectral efficiency maximization under power control, UAV’s trajectory to support the V2X service.
