5G V2X赋能车路协同系统
摘要
Abstract
Vehicle-road coordination is a new type of industry with deep integration of information and communication,intelligent automobile,transportation and traffic management,which is at the intersection of artificial intelligence,5G and transportation.As a key enabling technology,5G V2X wireless communication technology will help to build a"road-cloud-vehicle-human-network"collaborative vehicle networking ecosystem.Firstly,this paper introduces the definition,main construction contents and typical application scenarios of vehicle-road collaborative system.Based on the application traction,this paper studies the specific requirements of the directly connected communication in the 5G new air port-vehicle wireless communication(NR-V2X)technology applied to the autopilot scenario,and gives the description of the communication performance and security requirements in different business scenarios.Finally,according to the system requirements of low delay,high reliability and high concurrency of vehicle-road collaborative system,the related principles of 5G NR V2X physical layer,resource allocation,congestion control,Qos and security design are analyzed.关键词
