4. CJK IMT 25, Beijing, China 4/13 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. CJK IMT 25, Beijing, China 5/13 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
