To meet the communications demands of connected vehicles, the wireless devices deployed in vehicles and on roadside infrastructure may need access to more spectrum than is available today. This presentation describes a novel approach that allows connected vehicle devices using V2X technology (e.g., C-V2X or NR-V2X) to share spectrum with Wi-Fi and other unlicensed devices, thereby gaining access to more spectrum. Each vehicle dynamically and independently adjusts to its environment in a manner that gives connected V2X devices access to enough of the shared spectrum to meet their quality-of-service requirements, while leaving as much spectrum as possible for Wi-Fi. As a result, this approach uses spectrum more efficiently than the current approach of establishing one spectrum band exclusively for connected vehicles and another spectrum band exclusively for Wi-Fi and other unlicensed devices. The proposed approach uses a backward-compatible form of implicit beaconing that requires no change to Wi-Fi technology, so there is no need to replace Wi-Fi devices that have been deployed, and the approach requires only modest modifications to V2X which reduces cost and complexity. The approach also does not require involvement from a cellular operator or other centralized controller. Simulation results show that it is possible to protect quality of service for both V2X and Wi-Fi communications in a shared band, while achieving high spectrum efficiency. One spectrum band where this approach could be especially beneficial is adjacent to the Intelligent Transportation System (ITS) band, where this approach could help meet the needs of both connected vehicles and Wi-Fi 6.
