Demo Setup ITU workshop, Geneva, Switzerland 2016 - p 2

RAN Slicing and Sharing Sample Results  3 slices:  Slice-specific scheduling  Dynamic Slice Resource management – Enforce different policies over time DL Rate DL Throughput 6000 0.7 eMBB Slice DL Throughput eMBB Slice DL Throughput URLLC Slice DL Throughput URLLC Slice DL Throughput 0.6 mMTC Slice DL Throughput 5000 mMTC Slice DL Throughput Complementary CDF DL Throughput (kB/s) 0.5 4000 0.4 3000 0.3 2000 0.2 0.1 1000 0 0 1000 2000 3000 4000 5000 6000 0 Rate(KB/s) 0 1 2 3 4 5 6 Time(ms) 4 x 10 ITU workshop, Geneva, Switzerland 2016 - p 3

Backhaul Control Channel Requirements Measurement Results Control-channel- Agent-to-controller Controller-to-agent latency  Realtime Control requires low-latency high capacity backhaul ITU workshop, Geneva, Switzerland 2016 - p 4

Fronthaul Requirements Measurement results 5MHZ, SISO, FDD 10MHZ, SISO, FDD  Fronthaul capacity depends on man factors  Split, compression, protocol, BW, #RE/UE/RRU, #Antenna/Sectors, #CC ITU workshop, Geneva, Switzerland 2016 - p 5

Converged Flexhaul for 5G  Tow type of xhaul MME RRC 5G CORE and Control  Low latency Capacity-Limited Backhaul High capacity Backhaul  High latency Heterogeneous  Various topologies MME RRC PDCP  multi-tier – flat “RAN” Cloud  Mesh – tree 5G-RLC LTE-RLC 5G-MAC LTE-MAC  Switching vs 5G-PHY LTE-PHY routing Higher latency FH Split  Aggregation Low latency FH Split  Distribution WIFI 5G-RLC LTE-RLC  Data-plane MAC 5G-MAC LTE-MAC WIFI 5G-PHY LTE-PHY PHY 5G-PHY accelerations LTE-PHY Radio Radio  DPDK, NETMAP ITU workshop, Geneva, Switzerland 2016 - p 6
