摘要： A method of transmitting packet data to a receiver in a communication system using a Hybrid ARQ technique is disclosed. In accordance with one illustrative embodiment of the present invention, an index representative of how much the first packet being transmitted such as a signal-to-noise (Eb/No) ratio is compared to a predetermined threshold value when an error is occurred during the step of decoding the packet. If the index is greater than or equal to the threshold value, the first packet transmitted is stored in a buffer and a receiver requests to transmit a second additional packet encoded with a lower code rate. On the other hand, if the index is less than the threshold value, the receiver requests to re-transmit the first packet encoded with the same code rate.
