  4. LTE-A Evaluation Process • Full scale evaluation of LTE-A FDD • Contribution based Approach • Members submit contribution (simulation results) • On-line/Off-line meetings to discuss the technical issues including detailed simulation configurations • Evaluation report after the consensus • For non-simulation results, we validate the self-evaluation report

  5. Summary of Simulation Results • In all four configurations (InH, UMi, UMa, RMa), the simulation results show that LTE-A meets the ITU-R requirements • Most of simulation configurations and parameters are from 3GPP’s self-evaluation • For some configurations, Rel-8 features are enough to meet the requirements • We try several antenna deployment configurations for the full buffer simulation • Our numbers are similar to 3GPP’s self-evaluation

  6. CSE and CEUSE (DL) • MU-MIMO 4 x 2 (c) configuration

  7. CSE and CEUSE (DL) • Rel-8 SU-MIMO 4 x 2 (a) for InH and RMa • MU-MIMO 8 x 2 (c) for UMi and UMa

  8. CSE and CEUSE (UL) • Rel-8 SIMO 1 x 4 (c) configuration

  9. CSE and CEUSE (UL) • SU-MIMO 2 x 4 (a)configuration

  10. VoIP Capacity

  11. Mobility Spectral Efficiency

  12. For Non-Simulation Metrics • We have checked the following items of the 3GPP’s self evaluation by inspection and analysis • Control Plane Latency • User Plane Latency • Handover Interruption Time • Peak Spectral Efficiency

  13. Thank you
