摘　　要：铁路5G-R网络即将进入工程建设阶段,为做好前期工程技术储备,需提前研究5G-R网络特点与网络规划技术。5G-R网络与运营商5G网络有较大不同,主要提供给铁路工作人员使用,覆盖目标为铁路沿线,是铁路上一代移动通信系统GSM-R技术的演进。通过全面总结梳理5G-R的系统架构、网络覆盖、组网技术、业务特点、设备冗余、网络性能等特点,研究5G-R网络规划技术,包括频率、覆盖、容量、参数、室分、切换等关键技术,提出5G-R网络规划建议,为后续工程部署提供技术支撑。The railway 5G-R network is ready for the engineering construction. In order to provide technical reserve for the preliminary engineering stage, it is necessary to study the characteristics of 5G-R network and network planning technology in advance. The 5G-R network, different from the operators’ 5G network, is mainly available for railway staff and covers the railway line. It is upgraded based on the previous generation of railway communication system-GSM-R technology. By comprehensively summarizing and reviewing the characteristics of 5G-R system architecture, network coverage, networking technology, business characteristics,equipment redundancy, network performance, etc., we study the network planning technology with 5G-R characteristics based on the above characteristics, including frequency, coverage, capacity, parameters, indoor distribution, switching and other key technologies. On this basis, this paper puts forward 5G-R network planning suggestion, which can provide technical support for subsequent project deployment.
