30 5GIC approach Starts from end user QoE (H2H, H2D, D2D) Unlike 2G.4G, designed for end device Capacity & Energy efficiencies, Latency, Reliability Speed is not the differentiator between 5G and previous generations Latency e2e and radio access 5G should start with high density cells macro cells 1G.4G started with macrocells small cells Spectrum and system agnostic No difference between licenced and licenced-exempt bands Broadcast, Cellular, WiFi technologies (Data, Video, Audio) 30

31 New Air-Interface? Ultra Dense Cells Scalable to Medium and low density cells From narrow band to broadband services 31

32 New Air-Interface and New KPIs Objectives NOT link spectral efficiency Low control signalling overhead for management, No stringent time frequency control as in OFDMA Light MAC protocol Support fast and reliable spectrum sensing for opportunistic spectrum sharing with and without database support Highly energy efficient Flexible implementation of carrier aggregation across highly fragmented spectrum including license exempt band Allow full duplex operation Sub millisecond Air Interface latency Scalable for device to device and machine type communications 32

33 Will 5G provide Higher Speed? Main reasons Low latency: Full utilisation of advanced techniques potentials QoE: Fast network responses 33
