1 The METIS view of 5G networks Dr. Olav Queseth, Ericsson METIS Internet Of Things, Oslo, Norway Page 1 Rationale Affordable and Sustainable METIS FP7 Concertation Plenary Meeting Page 2 1

2 METIS Vision METIS envisions a future where access to information and sharing of data is available anywhere and anytime to anyone and anything. Such an all-communicating world with no limits to information availability will fuel the anticipated socio-economic development and growth. METIS FP7 Concertation Plenary Meeting Page 3 METIS Science & Technology Objective To develop a concept for the future mobile and wireless communications system that supports the connected information society. To provide a system concept that supports times higher mobile data volume per area - 10 times to 100 times higher number of connected devices - 10 times to 100 times higher typical user data rate - 10 times longer battery life for low power Machine type communication - 5 times reduced End-to-End latency The system concept should be - efficient - versatile, and - scalable. and achieve these objectives at - similar cost and - energy consumption as today s networks.

3 Scenarios, Requirements and KPIs Provide a scenario framework that can be used in the technology-research and concept-development Identify challenging test cases addressing extreme requirements mainly from end-user perspective METIS FP7 Concertation Plenary Meeting Page 5 Spectrum Investigate ways to enable and secure sufficient access to spectrum for the future METIS wireless communications system by developing innovative spectrum-sharing concepts, e.g. LSA Conduct propagation measurement and modeling, including MMWs Should lead to: - substantial improvements in the overall spectrum utilization - significantly enhanced user experience Service requirements Overall Demand Spectrum Usage Collective Usage Concepts Coexistence & Compatibility Mobile data volume explosion Spectrum Management New Spectrum D2D METIS FP7 Concertation Plenary Meeting Propagation characteristics Page 6 Spectrum Sensing Ultra-dense Networks Moving Networks 3

4 Horizontal Topics Technical solutions to challenges posed by scenarios. Each one addressing parts of the METIS concept. Device-to-Device (D2D) Communication Massive Machine Communications Moving Networks Ultra-dense Networks Ultra-reliable Communications METIS FP7 Concertation Plenary Meeting Page 7 Device-to-Device (D2D) Communication Allows direct communication between mobile devices and exchange data packets between devices locally Motivation - Reduced power consumption - Increased throughput - Discovery of geographically close activities - Increased spectrum efficiency - Extended coverage - Growing number of devices to be connected in the future - Internet of Things Push shopping offer to users with D2D (general or personalized) METIS FP7 Concertation Plenary Meeting Page 8 4

5 Massive Machine Communications Wireless communication involving connection of a very high number of wireless sensors/actuators/devices to wireless access network of: - Typically Low data rates traffic - Often requirement for wireless sensors/devices of low cost & of low energy consumption To realise the vision of connected society where everything is connected, there is a need to devise the radio interface and access network accommodating devices of various characteristics and requirements METIS FP7 Concertation Plenary Meeting Page 9 Moving Networks Moving Networks refers to a moving and/or nomadic network nodes & terminals that benefit from context information - Robust high-data rate backhaul links for mobile terminals - Vehicle-to-X communications (V2X) - In-vehicle communication & networking (inside cars, busses, trains,...) - Moving & nomadic download & data sharing hot spots Motivation - Improve the integration of mobile terminals & nodes into the network - Improve the network capacity and provide new means for flexible network deployment in order to extend network coverage - Enable new V2X services to improve traffic safety and efficiency METIS FP7 Concertation Plenary Meeting Page 10 5

6 Ultra Dense Networks Comprises dense deployments of BSs of different properties: - different transmit powers, leading to macro, micro, pico or femto cells of different size - connected to different RATs (2G-5G, WiFi etc.) - static or moving / nomadic cells Residential building Office building Bus stop Nomadic cells Motivation Park area Lamp posts cells An increase in capacity per area, and user QoE, to response for traffic avalanche. In the long term, we will be facing fairly uncontrollable, dense and 3-dimensional constellations of APs connected in very different ways to the cloud METIS FP7 Concertation Plenary Meeting Page 11 Ultra-Reliable Communication To offer networking solutions and transmission schemes with increased dependability=availability*reliability Most of the current commercial solutions have 95% availability Reliability through - redundant topologies - robust transmission schemes - resilient protocols Motivation - Present ultra-reliable operation in military or public safety - The adoption of wireless technology in various emerging M2M applications requires wiredlevel reliability Bluetooth WiFi LTE METIS reliability Emergency Military The ambition is to make wireless a commodity almost as reliable as the electricity METIS FP7 Concertation Plenary Meeting Page 12 6

7 Possible 5G Concept Multiple Integrated Wireless/Access Solutions enabling the 2020 Information Society Ultra-reliable Communication (Very low E2E latency, multi-hop comm.) Device-to-Device (capacity, reliability, coverage, EE) Ultra-dense Networks (very high data rates, crowds) Massive Machine Communications (IoT, Very low cost & power) Moving Networks (Coverage, V2V, In-vehicle apps) METIS FP7 Concertation Plenary Meeting Page 13 Expected Output Concepts & Technology solutions for 5G to - Meet diverse requirements of future services - Connect diverse devices - Support 1000 X traffic increase Consensus & Global strategy to - Ensure lead on future communications system - Ensure early global consensus Unique Expertise allowing to - Conduct fundamental research at early point - Identify where a revolution or evolution from LTE-A is needed METIS FP7 Concertation Plenary Meeting Page 14 7
