Multi-hop relaying with mobile relay nodes mounted at the top of train cabins is a promising technology to overcome the high propagation loss, blockage and mobility sensitivity in millimeter wave band communication for high speed train. In this context, we aim to maximize the data rate for passenger-oriented applications under multi-hop mobile relay architecture. Adopting the system deployment and antenna configuration in 3GPP, based on the transmitting power configuration and instantaneous train position, we propose an approach to optimize the average transmission data rate by selecting the optimal multi-hop relaying scheme. The analysis and numerical results exhibit that the proposed multi-hop relaying strategies can outperform a single hop 5G link communication under certain transmitting power regimes and train position ranges, which can serve as feasibility analysis and guideline for a possible architecture in next generation train radio deployment.
