Method and apparatus for performing CSI prediction

A user equipment (UE) comprising:

• memory;
• and
• one or more processors coupled to the memory,
• wherein the memory store one or more computer programs including computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the UE to:
• receive a plurality of reference signals from a base station,
• estimate channel quality information (CQI) for an interval based on the plurality of reference signals, wherein estimating the CQI comprises obtaining at least one of mean mutual information per bit (MMIB) or effective exponential signal to noise ratio mapping (EESM),
• predict channel state information (CSI) based on the estimated CQI,
• perform post-processing conversion of the MMIB or the EESM to predict CQI,
• determine whether the predicted CQI is greater than the estimated CQI,
• report, to the base station, CSI based on the predicted CQI in case that the predicted COI is greater than the estimated CQI, and
• report, to the base station, the CSI predicted based on the estimated CQI in case that the predicted COI is less than or equal to the estimated COI.

A method performed by a base station, the method comprising:

• receiving a plurality of reference signals from a user equipment (UE);
• estimating channel quality information (CQI) for an interval based on the plurality of reference signals, wherein estimating the CQI includes obtaining at least one of mean mutual information per bit (MMIB) or effective exponential signal to noise ratio mapping (EESM);
• predicting channel state information (CSI) for the UE based on the estimated CQI;
• performing post-processing conversion of the MMIB or the EESM to predict CQI;
• determining whether the predicted CQI is greater than the estimated CQI;
• reporting, to the UE, CSI based on the predicted CQI in case that the predicted CQI is greater than the estimated CQI;
• and
• reporting, to the UE, the CSI predicted based on the estimated CQI in case that the predicted CQI is less than or equal to the estimated CQI.
