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