Determine the cellular technology adopted for C-V2X in China and the United States

Determine whether LTE or 5G NR will be adopted for C-V2X deployments in China and the United States.

Background

The paper explains that C-V2X has been selected as the only solution in China and the United States. However, the specific cellular technology underlying those deployments has not been settled, with LTE and 5G NR identified as the competing alternatives. The unresolved adoption choice affects the communication capabilities and technology assumptions relevant to future vehicular safety services.

References

In China and the US, C-V2X technology is currently being selected as the only solution, with some uncertainty about whether LTE or 5G NR will be adopted.
