It is an object to provide a wireless communication device configured to reduce a communication resource necessary for retransmission, so that data transmission efficiency can be improved. In this device, when an NACK signal is input from an error detecting unit (107), i.e., when receiving data have an error, a retransmission judging unit (109) carries out retransmission judgment processing to judge for every block whether or not block retransmission is required on the basis of an average value of an LLR of each decoding bit included in each block in a plurality of blocks comprised of the divisions of decoding bit sequences input from an LDPC decoding unit (106) in accordance with the magnitude of row weights. Further, the retransmission judging unit (109) judges the plurality of the blocks in order of larger magnitude of the row weights, so that, at the timing of such judgment that the retransmission of some block is required, the retransmission judging unit does not carry out the judgment of the block which has not been judged as to whether or not the retransmission is required. A control signal generating unit (110) generates feedback information based on the judged result input from the retransmission judging unit (109). |
