This document is the final deliverable of the METIS project on spectrum usage. It describes the technical solutions developed, especially enablers for coexistence, in order to address the scenarios, needs and requirements identified for 5G. After a brief introduction of the overall METIS methodology, spectrum sharing concepts developed and potential implementation strategies like the Spectrum Toolbox and the corresponding spectrum management architecture are presented. Based on this, spectrum usage options to support the generic 5G services considered in METIS are analysed. Details on the applicability of technical enablers for dedicated 5G spectrum usage scenarios are provided as well. Furthermore, the value of flexible use of spectrum is analysed from an economic perspective. Finally, initial conclusions on spectrum bands’ suitability for the 5G generic services are drawn.
