Ray-tracing simulation and analysis of propagation for 3GPP high speed scenarios

In this paper, the propagation for 3GPP high speed train (HST) scenarios is studied both at 30 GHz and 3.5 GHz. Urban, cutting and viaduct scenarios are modeled and simulated by using 3GPP deployment configurations. The optimum direction of beam is suggested in order to achieve the best coverage. Propagation at 30 GHz and 3.5 GHz are compared in terms of received power and Doppler shift. The wideband path loss parameters are modeled, and suggestions are provided to guide high-data-rate HST communication system design.
