摘要：
Embodiments for a method and apparatus of selecting a transmission mode between the subscriber and a base station are disclosed. One method includes determining a predictive window. Instantaneous channel quality measurements are averaged, wherein the averaging is dependent upon a size of the predictive window. A first estimate of the transmission mode is determined based on the averaged instantaneous channel quality measurements. A margin is calculated based on reception of a qualifying downlink transmission. The transmission mode is selected by updating the first estimate with the margin.
