Based on the type-Ⅱand type-Ⅲ Hybrid Automatic Repeat reQuest (HARQ) system and Rata Compatible Punctured Convolutional (RCPC) code, a new HARQ system is proposed in which F sub-packets could be transmitted in one data packet, at receiver the same F sub-packets are combined with each other to form a reliable packet equal to the punctured combined sequence after F retransmission. The optimal number of repeat sub-packets is obtained to improve the performance of new HARQ system. The new HARQ system has the advantages of type-Ⅱand type-Ⅲ HARQ system, When the type-ⅡHARQ has higher throughput than the type-Ⅲ HARQ at higher Signal to Noise Ratio (SNR), the throughput and the retransmission times of the new system is close to type-Ⅱ HARQ. The new HARQ system spares the redundancy bits, whereas the type-Ⅲ HARQ retransmits too much redundancy at high SNR. On the other hand when the type-Ⅲ HARQ has higher throughput than the type-ⅡHARQ at lower SNR, the throughput and average retransmission times are close to that of the type-Ⅲ HARQ. Unlike the too much retransmission times of type-ⅡHARQ in the low SNR, the new HARQ spare the number of retransmission times.
