Abstract :
Improved Channel Quality Indicator (CQI) reporting scheme which aims to reduce the required CQI signaling even when the downlink data activity is high by employing a CQI prediction method. According to this paper, Node B Expectations all the intermediary CQI reports between two subsequent CQI reports by utilizing a FSMC model of the wireless channel. The proposed prediction-based CQI reporting scheme Expected-CQI (E-CQI) is based on the optimum periodic CQI feedback scheme and which has the minimum reporting cycle of 2ms. Therefore, every 2ms a CQI report is either transmitted by the UE or Expected from Node B.
