  5. 5G Challenges & Scenarios

  6. 5G Challenges Large diversity of Use cases & Requirements Avalanche of Traffic Volume Massive growth in Connected Devices Further expansion of mobile broadband Additional traffic due to communicating machines “Communicating machines” Device-to-Device Communications Car-to-Car Comm. New requirements and characteristics due to communicating machines “1000x in ten years” “50 billion devices in 2020”

  7. METIS 5G Scenarios Super real-time and reliable connections Best experience follows you Great Service in a crowd Ubiquitous things communicating Amazingly fast bit-rate,delay simple devices, coverage Accessibility, densecrowds Accessibility, mobility delay, reliability

  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.

  15. 5G Concept: development Best effort Critical D2D Architecture Backhaul Air Interface #1 Goals 1000x traffic Direct MMC Gateway Air Interface #2 100x rate M2M Backhaul to moving 100x devices MN V2X Air Interface #N Nomadic nodes Backhaul 10x battery Air interface UDN Base Layer SON 5x lower latency URC-E URC-S URC METIS Concept URC-L

  21. Beyond Uplink & Downlink: two-way comm. FBS • Traditionally, the design of the UL and the DL is decoupled • Wireless network coding allows optimization of the two-way communication instead of decoupling BS FBS FBS

  22. HT: Device-to-Device (D2D) Communication D2D Content sharing Push shopping offer to users with D2D (general or personalized) • Description:Controlled by the network, direct D2D communication allows direct communication between mobile devices and exchange data packets between devices locally • Objective:Integrate direct D2D operation modes as a part of the overall METIS systems • Motivation • End user benefits: Reduced power consumption; Increased throughput; Discovery of geographically close activities; • Operator benefits: Increased spectrum efficiency; Extended coverage; Growing number of devices to be connected in the future; Internet of Things
