摘要
随着5G时代的到来,车联网将借助通信技术的发展,实现车与车、车与人、车与网络平台的全方位连接,以提升汽车智能化和网联化水平。LTE-V2X技术是车联网通信中重要的技术组成部分,是3GPP(第三代合作伙伴项目)组织在Release 14由D2D(Device-to-Device)直联通信演进得到的新型V2X通信技术。实验室测试是LTE-V2X终端产业化的基础与保障,本文从LTEV2X终端的实验室射频和性能测试意义入手,讨论其各项测试指标和测试条件,最终研究得出适合现阶段标准发展的实验室测试方法,为LTE-V2X终端的商用提供实验室测试基础。
Telematics will realize the all-around connection between vehicles,vehicles and people,and vehicles and network platforms with the development of 5 G wireless communication technologies,that aim to improve the level of interconnection and intelligence of telematics.LTE-V2 X technology is an important technical component of telematics.It is a new V2 X communication technology developed by The 3 rd Generation Partnership Project(3 GPP)in Release 14 comes from D2 D(device-to-device)direct communication.Laboratory test is the basis and guarantee of terminal industrialization for LTE-V2 X technology.This paper begins with the LTE-V2 X terminal's RF and performance test in laboratory,further discuss test indicators and conditions,finally,obtain the test methods in laboratory that are suitable for the current standards' development.All the jobs above provide a test foundation for commercial of LTE-V2 X terminals in lab.
