摘要
随着移动互联网、物联网以及无线传感技术的广泛应用,车联网成为实现未来智慧交通和智慧城市的关键途径之一。伴随着3GPP LTE-V2X标准的研究与制定,基于蜂窝网的V2X技术成为继DSRC之后车联网的又一个研究热点,为车联网高可靠、低时延的需求提供了重要保障。首先简要介绍了车联网的发展历程,总结了V2X所涉及的业务场景和相应的技术指标,然后介绍了V2X关键技术,包括网络架构和资源调度等。最后给出了中国联通车联网的演进策略。
The wide spread applications of mobile Internet, IoT and wireless sensing technologies make IoV becoming one of the key technologies to realize the smart transportation and smart cities in the future. With the research and standardization of the LTEV2X in 3GPP, V2X based on cellular has become another research hotspot of IoV after DSRC, which provides an important guarantee for the basic performance requirements of IoV such as low latency and high reliability. Firstly, the development of IoV is briefly introduced, and the key service scenarios and the corresponding technology KPIs are summarized. Then the key technologies including network architecture and resource scheduling are summarized. Finally, it describes the evolution strategies of IoV of China Unicom in the future.
