Systems and methods for predicting the signal-to-interference-and-noise ratio (SINR) of the signal to be received by a mobile station transmitted from a base station in a wireless data communications system, for the purpose of forward link data rate control in the presence of partly periodic SINR fluctuations. The invention involves determination of a periodic mean SINR component in the received SINR process, and upon such determination the activation of a method which comprises a periodic mean SINR estimator, a subtractor which subtracts the periodic component from the received SINR process to produce an intermediate SINR process, a generic predictor which may be used to perform predictions on the intermediate SINR process, an adder which adds back an appropriate mean value to the intermediate SINR prediction. The resulting final SINR prediction is then used for rate selection.
