I. Introduction
To address spectrum congestion in the current 2.4 and 5 GHz Wi-Fi bands, the Federal Communications Commission (FCC) allocated the 6 GHz band for unlicensed use alongside existing incumbents, mainly fixed microwave links, cable television relay services (CTRS), satellite, and mobile Broadcast Auxiliary Services (BAS) [1]. The 6 GHz band is composed of four Unlicensed National Information and Infrastructure (U-NII) bands: U-NII-5 (5.925-6.425 GHz), U-NII-6 (6.425-6.525 GHz), U-NII-7 (6.525-6.875 GHz), and U-NII-8 (6.875-7.125 GHz), as shown in Table I.
