The invention proposes an improved HARQ scheme with low complexity. In accordance with the technical scheme of the invention, each retransmission is interleaved with different interleaving rules at each time of each retransmission of a data block that receives the demodulation error, while the same symbol modulation process is maintained. According to a preferred embodiment of the invention, in a demodulation error of data blocks each retransmission, each with different interleaving rules interleaved, while maintaining the symbol modulation processing and subcarrier mapping processing the same, so that the data block in the receiving and can get equal with the constellation rearrangement and frequency diversity effect, thereby improving the performance of HARQ technology. Compared with other existing improved HARQ technologies, the preferred implementation scheme is relatively simple in hardware implementation.
