摘要：
The transmission power of mobile terminals is one of the key factors that affect the distances between 5G-R base stations. Selecting a reasonable terminal transmission power parameter is of great significance for expanding the distances between base stations, making full use of the resources in existing base station sites along the railway lines, and saving the deployment costs for 5G-R base stations. First of all, based on the 5G-R service and function requirements, the bandwidth requirements of different types of mobile users are obtained. Then, based on the uplink demand, the base station spacing of the 5G-R mobile terminal with 200 mW and 2 W transmission power is estimated by using theoretical calculation and simulation. The results show that, compared with 200 mW, the distance between 5G-R base stations is 1. 79-2 times greater than that of the original 5G-R base stations when the terminal transmission power is 2 W. Using typical engineering parameters of high-speed railways, with an uplink transmission rate of no less than 1 Mb.s-1 at the edge of the community and a terminal transmission power of 2 W, the distance between 5G-R base stations in suburban open areas can reach 3. 3-4. 0 km (RRU on the tower). Mobile terminals should determine their appropriate power levels of uplink transmission according to their individual uplink traffic. It is suggested that the 5G-R communication module of the on-board integrated transmission equipment should use 2 W transmission power. © 2023 Chinese Academy of Railway Sciences.
