Analysis of the support 5G networks can offer in terms of delay and spectrum to V2X Use Cases.

What is it about?

5G networks are expected to be a key enabler to support autonomous driving. During the past years, multiple use cases have been defined and several standardized solutions have been specified. Although significant breakthroughs have been achieved, it is still under investigation if existing solutions are able to fully support all requirements for all levels of autonomous driving automation. This paper provides a harmonized view of the requirements for the latest and most advanced autonomous driving use cases. It also investigates the extent of support 5G networks can offer to these use cases in terms of delay and spectrum, and identifies open issues and discusses trends and potential solutions that could tackle them.

Why is it important?

Delay will be a critical factor for V2X Use Cases as control plane delay could affect seriously V2X services. It is not realistic to assume that all vehicles will be always connected to the network due to the scarce radio resources. Spectrum requirements depend on the needs and the implementation of V2X Use Cases. Most of them have modest needs. However, some of them require the transmission of high-definition video and maps and create significant challenges due to the low spectral efficiency of the Uplink and Sidelink. In our paper we have identified current shortcomings and also discussed research trends that could be further investigated to address the above-mentioned setbacks.
