Bit Loading Using Imperfect CSIT for Prediction-Based Resource Allocation in Mobile OFDMA

We present a prediction-based resource allocation algorithm (RA) for orthogonal frequency-division multiple-access (OFDMA) downlink, where inaccuracies in the wireless channel predictions are accounted for in the problem formulation. As the prediction quality significantly degrades with the predicti...
