A method and apparatus are provided for minimizing overhead in packet re-transmission in a communication system. Each packet is given a sequence number, based on a current transmission rate, the size of the packet, and a previously assigned sequence number. The packet size can be adapted so that the entire packet fits into a single transmission block. The packet size may also be adapted based on throughput. The packet size may be adapted based on the transmission rate and/or throughput, whether the packet is being transmitted the first time or if it is being re-transmitted. Alternately, if the packet is being re-transmitted, the packet is transmitted at its original transmission rate, regardless of the current transmission rate. |
