  • Summary

    This chapter investigates a variety of scenarios involving cooperative communications for networks that incorporate UAVs. We particularly analyze the role of cooperative communications in improving the connectivity and capacity of cellular-connected UAV user equipmentleveraging principles ofcoordinated multi-point (CoMP) transmissions among ground base stations. We then study how one can effectively use multiple quadrotor UAVs as an aerial antenna array that acts as a single coordinated UAV base station to provide wireless service to ground users. The goal will be to maximize performance while minimizing the airborne service time for communication. We also characterize the optimal rotor's speed for minimizing the control time using theoretical postulates of bang-bang control theory.
