Abstract

A method and system for adaptively determining an operating point for a transmitter-receiver pair in a wireless communication network. The receiver receives data over an uplink and measures an average observed word error rate avg.sub.-- WER of the received data and transmits the average observed word error rate avg.sub.-- WER over a downlink to the transmitter when the average observed word error rate avg.sub.-- WER is not within an acceptable word error rate range. The transmitter receives the average observed word error rate avg.sub.-- WER over the downlink and determines a power-code pair (P,c) for the transmitter based on the average observed word error rate avg.sub.-- WER. The power code pair (P,c) defines an operating point of the transmitter, where P of the power-code pair is a selected transmit power level of the transmitter and c of the power-code pair is a selected forward error correcting code used for encoding the data. The receiver can also determine a predicted word error rate WER.sub.pred for a first timeframe based on the observed word error rate WER.sub.obs for a second timeframe, and determines whether the predicted word error rate WER.sub.pred is within the acceptable word error rate WER range.
