Summary:
A new and flexible approach to spectrum usage and management is required in order to fulfil the requirements identified by the 5G PPP in their KPIs for 5G networks, e.g., 1000 times higher mobile data volume per geographical area or 10 to 100 times more connected devices. Many spectrum sharing schemes have been proposed so far (such as LSA, CBRS with SAS, LAA/LWA), and some of them have been tested in the field trials providing useful insights into the spectrum sharing issues. From a real implementation perspective, the above solutions can be applied in various contexts (e.g., for TVWS, or with the use of dedicated databases supported by sensing function), however it is envisaged that more flexible approaches to spectrum sharing (such as innovative Pluralistic Licensing or various cognitive radio oriented schemes) should be pursued and investigated further. However, in conjunction with new approaches to spectrum management and sharing, the network architectures are evolving and incorporating concepts of virtualization and software control. A significant push towards Software Defined Networking (SDN) and Network Function Virtualization (NFV) is being made by all major players involved in realizing the 5G vision including researchers, network operators and regulators. In this talk, various spectrum management systems will be presented together with the analysis of prospective spectrum virtualization approaches that utilize network graphs. This talk will also cover selected findings from the COHERENT project.
