In practical wireless environment, channel status always changes due to the movements of mobile terminals, and hence it is difficult to ensure the system efficiency by using single multiple input multiple output (MIMO) mode. Actually, various transmission and multiple input multiple output (MIMO) modes are defined in long term evolution (LTE) system. For different channel conditions, the base station...
In order to adapt channel variation and maximize throughput performance, Adapt Modulation and Coding (AMC) is used in Long-Term Evaluation (LTE) downlink. However, due to the wireless channel random variation, inaccurate reported Channel Quality Indicator (CQI) is introduced, which will affect quality of data transmission. Therefore, it is necessary to modify reported CQI in AMC process. Although...
