Introduction Vehicular networking studies have mainly focused on driving safety, driving efficiency, and entertainment in road networks. The Federal Communications Commission (FCC) in the US allocated wireless channels for Dedicated Short-Range Communications (DSRC) [DSRC], service in the Intelligent Transportation Systems (ITS) Radio Service in the 5.850 - 5.925 GHz band (5.9 GHz band).

Correspondingly, the support of enhanced V2X (eV2X)-based services by future converged and interoperable 5G systems is required. The 3GPP Technical Report [TR-22.886-3GPP] is studying new use cases and the corresponding service requirements for V2X (including V2V and V2I) using 5G in both infrastructure mode and the sidelink variations in the future. -Appendix B.
