Query: An Edge Computing Empowered Radio Access Network With UAV-Mounted FSO
  Fronthaul and Backhaul: Key Challenges and Approaches   One promising approach to address the supply-demand mismatch between the
terrestrial infrastructure and the temporary and/or unexpected traffic demands
is to leverage the unmanned aerial vehicle (UAV) technologies. Motivated by the
recent advancement of UAV technologies and retromodulator based free space
optical communication, we propose a novel edge-computing empowered radio access
network architecture where the fronthaul and backhaul links are mounted on the
UAVs for rapid event response and flexible deployment. The implementation of
hardware and networking technologies for the proposed architecture are
investigated. Due to the limited payload and endurance as well as the high
mobility of UAVs, research challenges related to the communication resource
management and recent research progress are reported.
