Currently and thereafter, evaluations and consensus-building process will be performed for the 4G candidates from ITU-R membership, standards organizations, and other external evaluation groups. Among them, the Chinese Evaluation Group (ChEG) is also responsible for submitting the evaluation report to ITU-R. This paper addresses the evaluation methodology and relevant activities. Descriptions to the basic rules in the evaluation are given, according to the requirements of ITU-R, where the simulation methods are highlighted. Next taking the 3rd generation partner project long term evolution advanced (3GPP LTE-A) as an example, the calibration steps of simulators are shown for the potential readers to reproduce the evaluation work. Finally the analysis and latest evaluation results for the multi-user multiple-input multiple-output (MU-MIMO) technology are presented, which currently is the most effective technology that could already achieve the requirements and still being improved. The improvement might include the methods of precoding and user group selection.
