Patent ID: 7826871

Claim:
A transmission apparatus of a multi-input multi-output (MIMO) communication scheme that simultaneously transmits different data from a plurality of antennas, the transmission apparatus comprising: an encoding section that collectively performs encoding processing on first data to be transmitted from each of the plurality of antennas; a modulating section that performs modulation processing on the encoded first data according to each corresponding antenna; a transmitting section that transmits the modulated first data from each corresponding antenna; and a transmission controlling section that controls transmission of the modulated first data to be transmitted from each of the plurality of antennas, wherein: when a data retransmission relating to the first data is performed, the transmission controlling section controls the data retransmission such that (i) not all of the first data previously transmitted from the plurality of antennas is included in the data retransmission and (ii) data included in the data retransmission excludes any part of the first data previously transmitted from at least one of the plurality of antennas.
