Patent ID: 8086927

Claim:
A multi input multi output transmitting apparatus that comprises a plurality of transmitting antennas, the multi input multi output transmitting apparatus comprising: an error correction coding section that carries out error correction coding of information bits to generate transmission bits, wherein the transmission bits comprise a plurality of bits; an interleaving section that carries out interleaving of the plurality of bits, wherein the interleaved plurality of bits form symbols to be simultaneously transmitted from the plurality of transmitting antennas; and a transmitting section that simultaneously transmits the symbols formed by the interleaved plurality of bits from the plurality of transmitting antennas, wherein, when the plurality of bits are retransmitted, the interleaving section carries out interleaving of the plurality of bits using an interleave pattern which is different from an interleave pattern used in a last transmission, such that at least one bit of the plurality of bits is allocated to one of the transmitting antennas which is different from another one of the transmitting antennas to which the at least one bit was allocated in the last transmission.
