铁路5G-R基站节能方案研究

Research on Energy Saving Scheme of Railway 5G-R Base Station

铁路新一代移动通信系统将采用5G-R系统。5G系统采用大规模天线,具有大带宽、高频率等特点,因此5G-R基站的用电量远高于GSM-R基站。为此从硬件、软件两个方面对5G基站节能技术进行分析,并对5G基站新工艺、新材料、仿生外观、符号关断、通道关断、载波关断和深度休眠等节能技术在铁路中的应用进行适应性分析;提出基于5G-R无线组网和话务量的节能方案,以及基于行车间隔的智能化节能方案,可为未来5G-R技术研究和工程建设提供参考。

The 5G-R system will be adopted as Chinese railway’s new generation mobile communication system.Because the 5G-R system adopts large-scale antennas with large bandwidth and high frequency,a 5G-R base station consumes much more electricity than a GSM-R base station.Firstly,this paper analyzes the energy saving technology for 5G base stations in term of hardware and software,and analyzes the adaptability of applying energy saving technologies in 5GR base station,such as new technology,new material,bionic appearance,symbol off,channel off,carrier off and deep hibernation.Meanwhile,an energy saving scheme based on 5G-R wireless network and traffic volume and an intelligent energy saving scheme based on traffic interval are proposed,which offers reference for future research and engineering construction of 5G-R technology.
