Abstract:
1. A method for controlling wireless communications, said method comprising: transmitting a voice packet from a base station to a communication unit at a rate faster than a generation rate of the voice packet, wherein the difference in rate between the transmission and generation of the voice packet creates spare bandwidth; determining whether the transmitted voice packet is successfully received; and retransmitting the voice packet using the created spare bandwidth if the voice packet was not successfully received, a number of retransmissions limited by a predetermined value based upon (i) monitoring a difference between a number of outbound voice packets generated at the base station and a number of outbound voice packets successfully transmitted by the base station, the difference representing a number of the outbound voice packets generated that have accumulated in a communication buffer of the base station, and (ii) limiting the number of the outbound voice packets accumulated in the communication buffer to the predetermined value.
