Direct-V2X Support with 5G Network-Based Communications: Performance, Challenges and Solutions

Abstract

This study analyzes the feasibility of supporting critical V2X services using 5G network-based Vehicle-to-Network-to-Vehicle (V2N2V) communications. The study evaluates the end-to-end latency of 5G V2N2V communications under different network deployments in single and multi-operator scenarios. The study shows that critical V2X services can be supported using 5G V2N2V communications over MEC-based network deployments. However, this requires the use of local peering points and shared data centers or MEC federation to address challenges arising from asymmetric network deployments. This opens the possibility for V2N2V communications to complement direct Vehicle-to-Vehicle (V2V) connections for increased reliability or to offload traffic under sidelink network congestion
