ABSTRACT

The emerging unmanned aerial vehicles (UAVs) have been playing an increasing role in the military, public, and civil applications. Very recently, 3GPP has approved the study item on enhanced support to seamlessly integrate UAVs into future cellular networks. Unlike terrestrial cellular networks, UAV communications have many distinctive features such as high dynamic network topologies and weakly connected communication links. In addition, they still suffer from some practical constraints such as battery power, no-fly zone, etc. As such, many standards, protocols, and design methodologies used in terrestrial wireless networks are not directly applicable to airborne communication networks. Therefore, it is essential to develop new communication, signal processing, and optimization techniques in support of the ultra-reliable and real-time sensing applications, but enabling high data-rate transmissions to assist the terrestrial communications in LTE. In this talk, we discuss three scenarios: First, for UAV sensing applications, we obtain realtime profiling of fine-grained air quality index distribution using sparse optimization techniques. Second, for UAV communication scenarios, we conduct spectrum sharing planning for UAV relaying systems to enhance 5G communications. Finally, to control a large number of UAVs, we propose mean field game approaches.
