1. there is the receiver for radio communication of hybrid automatic repeat-request HARQ mechanism, including:

  • The first combiner in the first position along line of reasoning footpath, receiving area;

    At the second combiner of the second position different from described primary importance along line of reasoning footpath, described receiving area, wherein,Described first combiner and described second combiner is connected in series and in different process levels;

    Controlling logic, it is configured to;

    select described first combiner, with based on the first HARQ transmission received in the channelSignal data generate a HARQ and merge signal data, wherein this selection merges signal data at least based on being used for storing HARQThe headroom of buffer and the order of modulation of the first received HARQ transmission;

    And select described second combiner, with baseSignal data in the second HARQ transmission received in described channel generates the 2nd HARQ and merges signal data, wherein this choosingSelect the described headroom at least based on the described buffer for storing HARQ merging signal data and the 2nd received HARQThe order of modulation of transmission;

    AndAt least one buffer, is used for storing a described HARQ and merges signal data or described 2nd HARQ merging signal numberAccording to.
