Twenty years before, 75 MHz of spectrum had been allocated to Intelligent Transportation Systems (ITS). Some of that spectrum was particularly well suited for the next generation of Wi-Fi technology (Wi-Fi 6), which would greatly benefit from primary or co-primary access to160 MHz of contiguous unlicensed spectrum.

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 ...
