Diverse applications have witnessed the prevalence of unmanned aerial vehicles (UAVs) due to their agility and versatility. Compared with computation and control, the communication tends to be the bottleneck of the whole UAV system. Cyber physical system (CPS), which achieves the integration of the cyber and physical domains, can inspire us to deal with the communication problems through a cross-disciplinary method. To this end, we first expound the coupling effects of computation and control to communication. Then, we propose a novel CPS framework for UAV communications. By extending the dimension of communication decisions to computation and control, the framework can precisely orient and settle the communication issues. Further, a quantitative energy optimization model is established to guide the protocol and algorithm design for UAV communications. Case simulation results validate the CPS framework in terms of the energy consumption and communication delay.
