【摘要】 V2X(vehicle to everything)通信是车联网中实现环境感知、信息交互与协同控制的重要关键技术。大唐电信科技产业集团最早提出并由中国企业主导的LTE-V2X国际标准作为其中的主流技术之一,能够在高速移动环境中提供低时延、高可靠、高速率、安全的通信能力,并能够最大程度利用TD-LTE已部署网络及终端芯片平台等资源。首先介绍了LTE-V2X的关键技术,并与IEEE 802.11p进行了比较;进而介绍了LTE-V2X的标准研究及其演进以及相关的产业发展和示范应用;最后展望了LTE-V2X的发展策略及其向5G NR-V2X的技术演进等,并提出了相关政策建议。更多还原

【Abstract】 V2X(vehicle to everything) communication is the critical technology to provide environment sensing, information exchange and cooperative control capabilities in vehicular networks. LTE-V2X, as one of the major V2X communication standards initiated and mainly driven by Datang Telecom, can enable low latency, high reliability, high data rate and security in communications, as well as scale economies by sharing the existing LTE network and terminal chipsets. LTE-V2X communication technology was introduced, and compared with IEEE 802.11 p standards. Then, the progress of LTE-V2X standardization, industrial research and development and trials and field testing works were provided. Finally, the development strategy of LTE-V2X and technical evolution towards 5 G was discussed.更多还原
