摘      要：High spectrum efficiency(SE)requirement and massive connections are the main challenges for the fifth generation(5G)and beyond 5G(B5G)wireless networks,especially for the case when Internet of Things(IoT)devices are located in a disaster ***-orthogonal multiple access(NOMA)-based unmanned aerial vehicle(UAV)-aided network is emerging as a promising technique to overcome the above *** this paper,an emergency communications framework of NOMA-based UAV-aided networks is established,where the disasters scenarios can be divided into three broad categories that have named emergency areas,wide areas and dense ***,a UAV-enabled uplink NOMA system is established to gather information from IoT devices in emergency ***,a joint UAV deployment and resource allocation scheme for a multi-UAV enabled NOMA system is developed to extend the UAV coverage for IoT devices in wide ***,a UAV equipped with an antenna array has been considered to provide wireless service for multiple devices that are densely distributed in disaster *** results are provided to validate the effectiveness of the above three ***,potential research directions and challenges are also highlighted and discussed.
