This presentation des cribes a novel approach that allows connected vehicle devices using V2X te chnology (e.g.\, C-V2X or NR-V2X) to share spectrum with Wi-Fi and other u nlicensed 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 mee t their quality-of-service requirements\, while leaving as much spectrum a s possible for Wi-Fi. As a result\, this approach uses spectrum more effic iently than the current approach of establishing one spectrum band exclusi vely for connected vehicles and another spectrum band exclusively for Wi-F i and other unlicensed devices. The proposed approach uses a backward-comp atible form of implicit beaconing that requires no change to Wi-Fi technol ogy\, so there is no need to replace Wi-Fi devices that have been deployed \, and the approach requires only modest modifications to V2X which reduce s cost and complexity. The approach also does not require involvement from a cellular operator or other centralized controller. Simulation results s how that it is possible to protect quality of service for both V2X and Wi- Fi communications in a shared band\, while achieving high spectrum efficie ncy. One spectrum band where this approach could be especially beneficial is adjacent to the Intelligent Transportation System (ITS) band\, where th is approach could help meet the needs of both connected vehicles and Wi-Fi 6.\n\nSpeaker(s): Jon Peha\, \n\nRoom: 353\, Bldg: Bannan\, 901 12th Ave\ , Seattle\, Washington\, United States\, 98122\, Virtual: https://events.v tools.ieee.org/m/519580 LOCATION:Room: 353\, Bldg: Bannan\, 901 12th Ave\, Seattle\, Washington\, U nited States\, 98122\, Virtual: https://events.vtools.ieee.org/m/519580 ORGANIZER:anewton@ieee.org SEQUENCE:35 SUMMARY:Vehicle-to-Everything (V2X) Communications in Unlicensed Spectrum C an Be Safe & Efficient URL;VALUE=URI:https://events.vtools.ieee.org/m/519580 X-ALT-DESC:Description: <br /><p class="MsoNoSpacing">To meet the communica tions demands of connected vehicles\, the wireless devices deployed in veh icles and on roadside infrastructure may need access to more spectrum than is available today.
