Abstract
The method and device of the present invention provide for efficient error correction in a packet radio system by 1) eliminating wasted bandwidth due to the unnecessary retransmissions that occur as a result of lost positive acknowledgments, 2) occupying less downlink bandwidth than a scheme requiring positive acknowledgments, and 3) minimizing packet delay by providing two levels of error correction at the datalink layer.
