对高铁宽带移动通信系统架构演进的思考

[摘要] 探讨控制面与用户面分离的高铁移动通信系统网络架构设计，以及相关的频谱融合和干扰协调问题。认为有别于公众移动通信系统，高铁移动通信技术包括两个重要的技术指标：传输性能和可靠性能，目前正是开展高铁高可靠和大容量移动通信系统研究的最佳时期。相关研究表明，对于未来高铁移动通信系统的高性能传输需求，需要更多地在物理层之上设计有效的解决方案。

[Abstract] This paper discusses decoupling of control plane from user plane, technologies for spectrum convergence, and interference coordination for high-speed railway (HSR) mobile communication systems. Unlike public mobile communication systems, HSR mobile communication systems have two important technical indexes: transmission performance and reliability performance. The author suggests furthering research highly reliable, high-capacity HSR mobile communication systems. Existing research shows that, to create high performance in future HSR, we should pay much more attention to efficient solutions in the physical layer.
