Architecture and Enablers of 5G V2X Network Slice

for Reliable and Low-latency Communications

Abstract— This paper presents a set of architectural solutions

for the connected car, by introducing a 5G V2X architecture

being able to work in multi-operator and multi-OEM scenarios.

5G technologies will enable vehicles to be connected to the

networks and also to be able to communicate with each other

with ultra-high reliability and very low latency. Leveraging such

kind of connectivity will enable disruptive new applications that

will allow improving driving efficiency and boosting road safety.

Objectives, use cases and results from the EC-funded 5GPPP

5GCAR project are presented, including a set of technology

components such as local end-to-end data paths, multi-link and

multi-RAT traffic flow and QoS management, location-aware

scheduling techniques, and 5G V2X Network Slicing.

Keywords—wireless communications; V2X; 5G QoS; Multi-

PLMN; Network slicing
