We highlight the potential of non-orthogonal multiple access (NOMA) integration withunmanned aerial vehicle (UAV) for future communications networks in beyond 5 gen-eration (B5G) networks to enhance cellular communication, support massive connec-tionsandincreasedatarates.Weconsiderascenario,whereaUAVcommunicatesin a downlink underlay cognitive radio based NOMA network (CR-NOMA) with twodestination users, a cellular device, and a primary destination following Nakagami-mfading distribution.We study the impact of perfect and imperfect successive interfer-ence cancellation (SIC) on outage probability (OP). To help analyze this impact,wederive exact outage results for different network users under perfect and imperfect SICconditions.Consequently,wemakeuseofMonteCarlosimulationstoconfirmtheanalytical results.
