TL;DR
This paper reviews 3GPP's NR-V2X sidelink communication standard, highlighting its features, developments in Rel-16, and future directions in Rel-17 for vehicular networks.
Contribution
It provides a comprehensive summary of NR-V2X standardization in 3GPP, emphasizing the Rel-16 release and upcoming Rel-17 enhancements.
Findings
NR-V2X offers high reliability and low latency for vehicular safety.
Rel-16 is the first 3GPP release to standardize NR-V2X sidelink.
Future Rel-17 aims to improve V2X communication capabilities.
Abstract
The 5G mobile network brings several new features that can be applied to existing and new applications. High reliability, low latency, and high data rate are some of the features which fulfill the requirements of vehicular networks. Vehicular networks aim to provide safety for road users and several additional advantages such as enhanced traffic efficiency and in-vehicle infotainment services. This paper summarizes the most important aspects of NR-V2X, which is standardized by 3GPP, focusing on sidelink communication. The main part of this work belongs to the 3GPP Rel-16, which is the first 3GPP release for NR-V2X, and the work/study items of the future Rel-17
