7 ITU-R Activities on 5G Three deliverables are under development in WP5D for IMT for 2020 and beyond, in preparation for World Radio Conference 2015 IMT VISION (recommendation) Roles of IMT Framework and overall objectives of the future development of IMT for 2020 and beyond Key capabilities and technical enablers TECHNOLOGY TRENDS (report) Technical aspects of terrestrial IMT systems in the time frame and beyond Includes the evolution of IMT IMT above 6 GHz (report) Technical feasibility of IMT in the bands above 6 GHz Ericsson Internal Page 7

8 IMT Vision Recommendation Traffic capacity 5G is expected to exceed the requirements of IMT-Advanced in all aspects, often by a magnitude Spectrum and bandwidth flexibility Achievable user data-rates [Mbit/s] high high 5G 4G 3G Mobility and coverage high Network and device energy high performance Latency [ms] high Massive number of devices Reliability Ericsson Internal Page 8

10 5G Spectrum Very wide range of spectrum relevant for 5G Low frequency bands for wide-area coverage (current cellular bands) High frequency bands for extreme capacity and data rates (> 10 GHz) 5G solutions needed for a wide spectrum range Spectrum range relevant for 5G 3 GHz 10 GHz 30 GHz 100 GHz Ericsson Internal Page 10

11 5G Spectrum Is a single radio-interface solution covering the entire range of spectrum relevant for 5G? One single radio-interface solution? 3 GHz 10 GHz 30 GHz 100 GHz Advantages Standardization/deployment effort Disadvantages Disregards differences in propagation, deployment and implementation Compatibility constraints at lower frequencies A single solution most likely not feasible! Ericsson Internal Page 11

12 5G Spectrum Possibility for LTE compatibility in lower bands highly beneficial Massive deployment of LTE devices in lower bands exist in 2020 Replacing LTE with new incompatible RAT loss of capacity and service for LTE devices 5G cellular access (higher performance, wider-area coverage) 5G mmw access (lower-complexity design, short-range) 3 GHz 10 GHz 30 GHz 100 GHz LTE compatibility highly beneficial Ericsson Internal Page 12

13 5G systems Evolution of existing standards + Complementary new technologies LTE, evolving enhancements New wireless technologies 5G Ericsson Internal Page 13
