no code implementations • 28 May 2021 • Khoi Khac Nguyen, Saeed Khosravirad, Daniel Benevides da Costa, Long D. Nguyen, Trung Q. Duong

In this paper, we propose reconfigurable intelligent surface (RIS)-assisted unmanned aerial vehicles (UAVs) networks that can utilise both advantages of UAV's agility and RIS's reflection for enhancing the network's performance.
