智能高铁中的5G技术及应用

5G Technologies and Applications in High-Speed Railway

介绍了面向智能高铁的5G场景及业务需求,并针对场景及业务分析了适用于智能高速铁路的大规模天线(MIMO)、超可靠低时延、大规模接入等5G关键技术。同时给出了3种智能高铁中的5G应用案例:5G智慧车站应用、5G物联网应用以及5G移动边缘计算(MEC)应用。认为5G多种关键技术将会为未来实现高速铁路的智能升级提供了有力的支撑。

Based on the overview of the intelligent high-speed railway, the scenarios and business requirements of 5 G for the intelligent high-speed railway are introduced. The 5 G key technologies such as massive multiple-input multiple-output(MIMO), ultra-reliable low-latency communications, and massive access are also analyzed. Meanwhile, three 5 G intelligent highspeed railway application cases, including railway station, 5 G Internet of things application and 5 G Mobile Edge Computing(MEC) application are presented. It concludes that 5 G key technologies will provide strong support for the intelligent upgrade of high-speed railways in the future.
