Abstract: 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 5GR network planning suggestion, which can provide technical support for subsequent project deployment.
