A new Hybrid-ARQ scheme with a convolutional code and the Viterbi decoding is proposed, which uses the packet combining technique and a retransmission criterion based on an estimated decoding error rate. The throughput and bit error rate are evaluated by theoretical bounds and computer simulations. It is shown that a given error rate tolerance can be attained with good throughput for any signal to noise ratio, i.e. for the slow time-varying channels. Furthermore, the throughput performance can be improved by retransmitting not all but a part of packet.
