Abstract:
1. A method for reverse link rate allocation in a wireless communication system supporting a plurality of data rates, the data rates having a corresponding set of transition probabilities for transitions between the plurality of data rates, the method comprising: measuring a forward link channel quality; adjusting at least one of the transition probabilities, wherein the adjusting comprises adjusting the at least one of the transition probabilities in response to the measured forward link channel quality; adjusting a maximum data rate for the reverse link in response to the measured forward link channel quality, wherein an increase to the maximum data rate results in an addition of one or more transition probabilities and wherein a decrease to an maximum data rate results in an elimination of one or more transition probabilities; and applying the transition probabilities to determine a transmit data rate for the reverse link, wherein a random number is generated and compared to the transition probabilities and the transmit data rate is increased or decreased depending on the comparison.
