The small cell solutions will be key element of a sustainable mobile broadband business Page 4 © NEC Corporation 2012
  5. 5. Performance, Small Cells VS Macro ISD=500m 3-sectors Micro ISD=200m 3.3x capacity” Dense Urban Macro Micro Tx power 40W 8W Antenna Height 30 meters 10 meters Spectrum 2.6GHz (10MHz) 2.6GHz (10MHz) Sectorization 3-sectors OMNI 2x faster! 3.3x capacity3.3x higher system throughput2x faster average user data rate @ 100Mbps/km2Far better cell edge/indoor performance Page 5 © NEC Corporation 2012
  6. 6. Performance, Small Cells in Het-Net Macro only Het-Net: Small cell & Macro (Up to Micro/Macro ratio =10 ) Macro eNB 3 Sector Macro Cell Micro eNB Micro Cell 1 Sector (Omni) System Throughput User Data Rate CAPEX and OPEX for Similar Capacity 1 1 1.0 10.8 0.8 0.8 0.8 Downlink Uplink 4x 9x CAPEX0.6 0.6 0.6 0.6 Downlink OPEX 6x 7x 4x0.4 0.4 0.4 Uplink 0.40.2 0.2 0.2 0.2 0 0 0.0 0 Macro Only Micro/Macro Micro/Macro Micro/Macro Macro Only Micro/Macro Micro/Macro Micro/Macro Macro Only Micro/Macro Micro/Macro Micro/Macro ratio =2 ratio =5 ratio =10 ratio =2 ratio =5 ratio =10 ratio =2 ratio =5 ratio =10 up to 6-7 times system throughput up to 4 times downlink and 9 times up to 75% less CAPEX compared to increased by Het-Net uplink user data rate improvement traditional Macro only approach Page 6 © NEC Corporation 2012
  7. 7. SON & Het-Net Future Het-Net outlook: e.g. Europe Het-Net Building Blocks SON Server LTE Coverage Layer Management Multiple Multiple tx 800MHz/1800MHz/2600MHz technologies power System LTE Capacity Layer EPC Multiple form Small Cells 1800MHz/2600MHz/3500MHz Multi-vendor factors GW Multiple SON Spectrum Server ConfigurationHet-Net Challenges Interference Macro cells and small cells at the same frequency Macro cells and small cells at different frequency Radio Resource HO, Load Balancing & Mobility Management Management All small cells (Femto & Pico/Micro) connected to GW Architecture Femto only connected to Femto GW – Pico/Micro connected directly to ePC Coordination & SON: Centralised, Distributed, Hybrid Management  Multi vendor SON Page 7 © NEC Corporation 2012
  8. 8. Multi-Vendor SON in Het-Net Het-Net is a new term for 3GPP HCS Het-Net is mainly used when there are two different RATs -> LTE Macro + LET small cell is not really a Het-Net 3GPP addresses most of the challenges in phases, Rel.9,10 and 11 Coordination in Het-Net is needed but the level of coordination depends on scenarios The SON architecture flavour, i.e. distributed, centralised or hybrid, varies between vendors Availability & openness of X2 and N-Int are important factor and will lead to different solutions by each vendor Macro vendor’s Hybrid Architecture NMS  SON functions are placed at the best suited position for each use case Macro Itf-N EMS NEC’s NEC EMS SON  NEC’s eNB executes SON-related Server measurements and short-term parameter updates, such as load balancing X2  NEC’s SON server executes statistical Macro eNB X2 analysis, long-term parameter updates and provide interwork function with other vendor’s NM-level SON over Itf-N Page 8 © NEC Corporation 2012
  9. 9. Multi-Vendor SON in Het-NetInterference Management: Cell Optimization  CCO, eICIC, ICIC (if X2 available)Resource Management:  Speed based HO, Enhanced Scheduler, Advanced QoS provisioning, Energy Saving, …Multi-Vendor SON in Het-Net Different Solutions depending on scenarios Interfered Mobile  Option 1: Macro-cell provides SON-related standardised information via X2 Various Options  Option 2: Macro-cell provides SON-related standardised information via O&M SON Option 1: Option 2: Option 3 Features X2 OAM NEC  Option 3: if the information could not be obtained PCI TS 36.423 TS 32.762 from macro vendors, a set of NEC specific eNB and S1, … ANR NA NA Info from UE, algorithms used- measurements or statistics MRO TS 36.423 TS 32.425 collected from NEC’s eNB or UEs.

  11. 11. Concluding Remarks The capacity crunch and spectrum shortage are both real The small cell solution will provide significant capacity, rapidly and at low cost Need small cells in a Het-Net environment with a more intelligent, automated, resilient and efficient SON system The small cells deployment is a paradigm shift and operators need to rethink their Models Different approach to deployment Macro-cell Vs Small Cell mainly with regard to  Backhaul, operation and management, cost, … Move away from macro: small cell ratio calculation in the cost analysis -> Cost: Mbs/Hz/Km² Cost analysis will be different if Macro LTE and small cell is carried out in isolation The site options, backhaul, regulation and cost needs to be carefully taken into account The Multi-Vendor SON for Het-Net is more of an IOT and vendor’s willingness to cooperate A mind set change is needed Page 11 © NEC Corporation 2012
