To expand the wireless communication system to automotive industry, LTE completed supporting the vehicle-to-everything (V2X) communication. The advanced V2X services (eV2X services) are categorized into four useful scenarios: vehicular platooning, advanced driving, extended sensors and remote driving, their common feature is the need for low latency. Even some scenarios have harsh requirements for latency, such as the communication scenario that emergency trajectory alignment between users supporting V2X application needs 3ms end-to-end delay. Although the 3ms delay requirement is demanding, for autonomous driving, this is the basic requirement for safe driving. In this article, we analyze the latency characters of the existing vehicular communication, and propose a feasible to meet the latency requirement to support the vehicular communication in 5G new radio (NR).
