The application of unmanned aerial vehicles (UAVs) in high-speed train (HST) communications is able to enforce railway safety and support high traffic. In this paper, we investigate the UAV-aided amplify-and-forward (AF) relay high-speed train communication system over generalized $\kappa-\mu$ fading channels. The UAV is typically energy constrained and can employ the simultaneous wireless information and power transmission technology to extend its battery lifetime. Considering the mobility of the UAV and the HST, we use the random direction mobility model to derive the statistical characteristics of the signal-to-noise ratio at the HST. Furthermore, we obtain the exact outage probability based on the practical time switching-based relaying protocol. Numerical results reveal the impact of the mobility, propagation environment, and channel parameters on the considered system. Finally, the optimal time switching factor is also obtained.
