dc.description.abstractCopyright © 2020 The Author(s). To improve the transmission flexibility of emergency communication scenarios, a joint user grouping and power allocation algorithm was proposed for UAV-aided non-orthogonal multiple access (NOMA) system. A sum-rate maximization resource allocation algorithm was formulated under the constraints of the maximum transmit power and the user grouping. To solve the non-convex problem, a graph-based user grouping algorithm was proposed to minimize the relative distance between the UAV and users. Based on the grouping result, the power allocation sub-problem was transformed into a convex one by using the auxiliary-variable approach. Simulation results demonstrate that the proposed algorithm has better performance in terms of sum rates.en_US
