7 METIS 5G Scenarios Super real-time and reliable connections
5G/METIS METIS 5G Scenarios Super real-time and reliable connections Best experience follows you Great Service in a crowd Amazingly fast Ubiquitous things communicating Let me give you an overview of the Future scenarios identified by METIS. They are shown on the top of the 5G previously shown sphere/picture. METIS has five major future scenarios based on five challenges - “Amazingly fast” focuses on high data-rates for future mobile broadband users, -“Great service in a crowd” focuses on mobile broadband experience even in the very crowded areas and conditions, - “Best experience follows you” focuses on end-users on the move with high levels of experience, and - “Super real-time and reliable connections” focuses on new applications and use cases with very strict requirements on latency and reliability. “Ubiquitous things communicating” focuses on efficient handling of a very large number of devices (including e.g. machine type of devices, and sensors) with widely varying requirements, bit-rate, delay simple devices, coverage Accessibility, dense crowds Accessibility, mobility delay, reliability © Ericsson AB 2013 7

11 Spectrum Scenario: Future Landscape
90% Seminar - Spectrum sharing concept part II Spectrum Scenario: Future Landscape Dedicated licensed spectrum complemented with various forms of shared spectrum In order to cope with the heavily increasing wireless data traffic in both human- and machine centric communications, radically more spectrum is needed for 5G system operation. The future development of regulation and technology will create a complex landscape of spectrum availability and access. Multiple frequency bands, subject to different regulation including various forms of shared spectrum, are expected to be available to wireless communication systems. Hence, technology needs to be designed in a flexible way so that it is capable of operating under different regulatory models and sharing modes. “Toolbox” of different sharing enablers required In order for 5G system to work under such scenarios

14 METIS 5G Concept A user-centric 5G system concept that efficiently integrates: the support of MMC and URC (ultra-reliable), 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.

20 Aggregation Network (local, regional, national)
METIS 5G Architecture Amazingly Fast scenario high data rates & network capacities Ultra-Dense Networks (UDN) ISD about 10 m >= 1 radio nodes per room Local break out & Distributed mobile core functions Accelerated content delivery Tech. Dependent D2D, MMC (Massive Machine Comm.), Moving Networks (MN), UDN Ultra-reliable Comm. (URC) Internet MMC D2D / URC MN UDN Aggregation Network (local, regional, national) Massive MIMO Wireless access Wireless fronthaul Wired fronthaul Wired backhaul Internet access C-RAN CoMP Mobile Core – Centralized Functions + OAM C-RAN + Mobile Core – Distributed Functions (incl. optional local breakout or CDN) Macro radio node* Small cell radio node*, e.g micro, (ultra-)pico, femto Note: Indoor cells not shown! Centralized or distributed? * Only Remote Radio Units (RRUs) assumed. It is hard to pinpoint the detailed architecture for the society, but for sure we can identify some key trends that will influenece it: (UDN, MMC + other METIS horizontal topic short overview) Add the information that the people are expecting high performance from wireless broadband, comparable to fixed line sollutions, and that they expect it both at home, stadium and while commuting in a bus A variety of solutions boosting the performance of the network already exist or are being developed (massive MIMO, CoMP etc). On the other hand the variety of use cases and high node densification will lead to a very flashy node activity pattern. In combination with the expect traffic avalanche foreseen for the next decade, solutions supporting energy efficient , scalable and flexible operations of the network infrastructure are a must.
