1. the receiver of radio communication of (HARQ) mechanism that is used to have mixed automatic repeat request comprises:

  • At least one buffer, be used to store the data of the HARQ transmission of previous reception, the HARQ transmission of described previous reception is divided into a plurality of encoding blocks and has incorrect decode messages, and the data of each in described a plurality of encoding blocks are HARQ composite signal data or decoded bits;

    At least one combiner is configured to produce described HARQ composite signal data for each encoding block based on the signal data of the HARQ transmission of the signal data of current HARQ transmission and described previous reception;

    Decoder is configured to generate described decoded bits based on described HARQ composite signal data for each encoding block;

    AndControl logic is configured to select for each encoding block based on choice criteria, and described HARQ composite signal data or described decoded bits are saved in described at least one buffer.
