Title: 5G Key Technologies for Intelligent High-Speed Railway

Abstract: The 5th generation mobile communication technology (5G) is a hotspot of research and attention in the international academia and industry. Multi-scene, multi-target and multi-technology integration are the important characteristics of 5G, which are different from other generations of mobile communication systems. The international telecommunication union (ITU), the world wireless research forum (WWRF), China 5G Standard Promotion Group (IMT-2020), the European Union 5G Research Organization (NGMN) and METIS all regard high-speed railway or high-speed mobility as an important scenario of 5G. High-speed railway is one of the typical vertical application industries of 5G.

This report aims at the business and application requirements of future high-speed railway development, points out the necessity and scientific significance of applying 5G technology to the intelligent high-speed railway system, and the application of 5G technology in the future high-speed railway communication systems are discussed from the aspects of high-speed railway service model, network architecture, millimeter-wave communication, large-scale antenna array, beam management, ultra-reliable low time delay, mobile edge calculation, network slicing, etc.
