Abstract:
1. A method of communications, comprising: transmitting a signal on a forward link of a communication channel, wherein the signal is transmitted over a plurality of time periods; receiving a plurality of feedback parameters on a reverse link of the communication channel that describe the quality of the signal transmitted on the forward link and correspond to the plurality of the time periods of the communication channel; filtering one of the feedback parameters at a first time period from the plurality of time periods to generate a first filtered parameter, filtering another of the feedback parameters at a second time period from the plurality of time periods to generate a second filtered parameter, wherein the second time period being proximal in time from the first time period; and generating a control signal as a function of the difference between the first and second filtered parameters; filtering a next feedback parameter from the plurality of feedback parameters received at a time period proximal in time from the second time period; and updating the control signal as a function of the next filtered parameter and at least one packet acknowledgement indicator, wherein the update is limited to a maximum difference between the second and the next filtered parameters.
