Abstract
A method and apparatus for data transmission is provided herein. In accordance with the preferred embodiment of the present invention a loss-ratio estimator () estimates a current loss (L) for a communication channel (). Once the actual loss for the channel is known, a generator () compares the actual loss (L) to a target loss (T). A retransmission control parameter (R) is then adjusted by the generator () and output to a transmitterwhere it is used to control the retransmission behavior and to determine when to abort a bad frame. When a bad frame is aborted, transmitterindicates the abortion to a receiving device (). A receiver then utilizes the indication to stop reporting the bad frame in all subsequent ACK/NAKs.
