  title={UAV-Aided Cellular Offloading: A Potential Solution to Hot-Spot Issue in 5G},
  author={Jiangbin Lyu and Yong Zeng and Rui Zhang},
In conventional terrestrial cellular networks, mobile terminals (MTs) at the cell edge often pose the performance bottleneck due to their long distances from the serving ground base station (GBS), especially in hotspot period when the GBS is heavily loaded. This paper proposes a new hybrid network architecture by leveraging the use of unmanned aerial vehicle (UAV) as an aerial mobile base station, which flies cyclically along the cell edge to serve the cell-edge MTs and help offload data…
