Abstract —Wireless communications relying on Unmanned Aerial Vehicles (UAVs) is a promising candidate in future communication systems. Compared with conventional terrestrial communications, UAV networks has some significant benefits including cost-effectiveness, mobility, fast deployment, higher probability of Line-of-Sight (LoS) links between UAV and ground terminals. Based on ideal conditions of high Signal-to-Noise Ratio (SNR), Non-Orthogonal Multiple Access (NOMA) with fixed power allocation factor is adopted to indicate performance of two users. These ground user from UAV is independent of channel and trajectory parameters is further evaluated under impact of imperfect channel state information (CSI). We drive the closed-form formula of outage probability for two ground users. Simulation results provide impacts of system parameters on outage behavior.
