摘要
车联网已成为全球汽车产业发展的重要战略方向,我国加快顶层设计规划布局,将研究并建设基于蜂窝车联网C-V2X(目前包括LTE-V2X与NR-V2X)技术的车用无线通信网络,并要求推动5G与车联网协同建设。在系统梳理3GPP和CCSA在C-V2X最新的标准化进展基础上,提炼了在四跨互联互通活动中发现的技术标准方面的问题,提出了我国完善C-V2X技术标准的参考建议。
The internet of vehicles has become an important strategic direction for the development of the global automobile industry. China accelerates the top-level design, takes the research and deployment of a wireless communication network for vehicles based on C-V2 X(now including LTE-V2 X and NR-V2 X) technology. And it is also required to promote the collaborative deployment of 5 G and the internet of vehicles. On the basis of reviewing the latest standardization progress of 3 GPP and CCSA in C-V2 X, the technical standards problems found in the C-V2 X "Four Layers" interoperability application demonstration were refined, and some reference suggestions were proposed for China to improve the C-V2 X technical standards.
