This paper proposes an alternative strategy that could meet the needs of both connected vehicles and Wi-Fi 6 by allowing them to share spectrum under an appropriate set of coexistence rules. This could be achieved through changes in spectrum regulations, modest changes in technology for those C-V2X devices that operate in the shared band, and no changes to Wi-Fi. This would give C-V2X devices access to spectrum that is adjacent to the ITS band (which was part of the ITS band until recently), while giving Wi-Fi 6 devices the contiguous 160 MHz that they need, all without modification to devices that have already been deployed. For simplicity we talk of “C-V2X” in this paper, but our approach is likely to apply similarly to successors of C-V2X, starting with 5G NR-V2X [6]. Our approach also supports sharing between C-V2X and unlicensed devices other than Wi-Fi, although this may require some change in how those devices access spectrum.
