Abstract

A processing system (206) defines (302) a plurality of bins (230) within a sliding time window, each bin for storing a total transmit duration of a predetermined number of frames assigned to each bin. The processing system then determines (310) a mean transmit duration per frame for a next one of the plurality of bins to be processed. The processing system subtracts (312) the mean transmit duration per frame from the total transmit duration of the one of the plurality of bins, when a next frame begins to be processed; and calculates (314) a transmit duty cycle for the sliding time window, the transmit duty cycle calculated as if a requested transmit duration for the next frame were to be allowed. The processing system also delays (316) a transmission of the next frame, when the transmit duty cycle is greater than a maximum allowable transmit duty cycle.
