11. Spectrum Scenario: Future Landscape • Dedicated licensed spectrum complemented with various forms of shared spectrum “Toolbox” of different sharing enablers required In order for 5G system to work under such scenarios

12. Toward 5G Concept: Technology Components Examples

13. Some 5G Technology Components New spectrum bands and access methods Nomadic nodes Buildings Bus stop 300 MHz 3 GHz 30 GHz 300 GHz Park area Lamp postsnodes Dense and moving networksMulti-hop wireless backhaul VL-MIMO Massive multi-antenna systems Context-aware interference and mobility management Air interfaces for new applications and reduced signaling Mobile Device-to-device

14. METIS 5G Concept • Auser-centric 5G system concept that efficiently integrates: • the support of MMC and URC, • the support of scalable data rates including very high data rates, • the support of scalable data rates including very low latencies, • for service provision to both consumers and devices/machines. • The system that fulfils these requirements be flexible to provide different services at different times. • The system architecture must provide native support for extreme Mobile Broadband (MBB) communication, MMC, URC, D2D, MN, and UDN.
