2 고객상담센터 조직구성 및 운영계획 Contents Introduction ChEG Evaluation Schedule Simulation Model and Assumptions CJK Eval SIG Time Schedule(Proposal)

3 고객상담센터 조직구성 및 운영계획 Introduction The reception of IMT-Advanced technologies will not be finished until Oct ‘09 ChEG is preparing the LTE-A evaluation platform and IEEE m evaluation platform We plan to participate in the LTE-A evaluation discussion in May ’09, 3GPP meeting Checking the IMT-A channel is one of our most important tasks. We would like to exchange our ideas on IMT-A channel implementation with CJK Eval SIG colleagues

4 고객상담센터 조직구성 및 운영계획 Sep ’09 May ’09 Apr ’09 Output the evaluation result of m technology …… Evaluate basic radio characteristics (e.g., geometry distribution, large scale loss distribution) Output the evaluation result of LTE-Advanced technology Compare the results with other companies or Eval Groups Focus on the SCM channel before Apr ’09 Check the accuracy of SLS ChEG Evaluation Schedule
