Technical Policy Options to Enable Shared Use of the Upper 6 GHz Band

This paper offers a review of technical policy options that should enable the possibility of shared use of the frequency band 6425–7125 MHz by 5G/6G public mobile systems as primary users and secondary Radio Local Area Network applications, such as Wi-Fi. The analysis focuses on a European case study and is made by reviewing the numerous spectrum co-existence studies considered there against a set of critical research questions. The findings are then compared with the body of technical evidence available in academic literature. Based on such critical comparative analysis, we propose a Spectrum Usage Rights-based licensing approach with a consolidated set of policy options that could constitute the regulatory framework to enable shared use of the upper 6 GHz band by 5G/6G and Radio Local Area Networks.
