摘要:

第三代合作伙伴计划(3GPP)最近发布了其版本16,其中包括基于5G新无线电(NR)空中接口的第一个车辆到一切(V2X)标准。5G NR V2X在5G NR空中接口之上引入了高级功能,以支持具有严格要求的连接和自动驾驶用例。本文介绍了用于V2X通信的3GPP Release 16 5G NR V2X标准的深入教程,特别关注侧链路,因为它是5G NR V2X最重要的部分。本文的主要部分是深入讨论5G NR V2X的关键方面:物理层,资源分配,服务质量管理,Uu接口的增强和V2N(车辆到网络)通信的移动性管理,以及5G NR V2X和LTE V2X之间的共存机制。我们还回顾了用例、系统架构,并描述了5G NR V2X的评估方法和模拟假设。最后,我们展望了可能的5G NR V2X增强功能,包括第17版中确定的增强功能。

英文摘要:

The Third Generation Partnership Project (3GPP) has recently published its Release 16 that includes the first Vehicle to-Everything (V2X) standard based on the 5G New Radio (NR) air interface. 5G NR V2X introduces advanced functionalities on top of the 5G NR air interface to support connected and automated driving use cases with stringent requirements. This paper presents an in-depth tutorial of the 3GPP Release 16 5G NR V2X standard for V2X communications, with a particular focus on the sidelink, since it is the most significant part of 5G NR V2X. The main part of the paper is an in-depth treatment of the key aspects of 5G NR V2X: the physical layer, the resource allocation, the quality of service management, the enhancements introduced to the Uu interface and the mobility management for V2N (Vehicle to Network) communications, as well as the co-existence mechanisms between 5G NR V2X and LTE V2X. We also review the use cases, the system architecture, and describe the evaluation methodology and simulation assumptions for 5G NR V2X. Finally, we provide an outlook on possible 5G NR V2X enhancements, including those identified within Release 17.
