An Overview of 3GPP Cellular Vehicle-to-Everything Standards

Abstract

With the growth of mobile data and devices, cellular networks have great potential to support various vehicular communication services for safety and non-safety applications. This paper presents an overview of the 3GPP cellular vehicle-to-everything (V2X) standards. We discuss various aspects of V2X standards, including types of V2X application support in 3GPP, requirements to support eV2X scenarios, different levels of automation, comparison of V2X and IEEE 802.11p, architecture, spectrum usage, and security and privacy for V2X services. Finally, we conclude this article with a review of typical V2X applications
