TRANSMISSION DEVICE AND TRANSMISSION METHOD
First Claim
1. A transmitting apparatus of a MIMO communication scheme that simultaneously transmits different data from a plurality of antennas, the transmitting apparatus comprising:
- an encoding section that collectively performs encoding processing on data to be transmitted from antennas of the plurality of antennas;
a modulating section that performs modulation processing on the encoded data according to the plurality of antennas;
a transmitting section that processes the modulated data so as to be transmitted from the corresponding antennas; and
a transmission controlling section that controls transmission of the data transmitted from the antennas,wherein when the data is retransmitted, the transmission controlling section retransmits data transmitted from less antennas than the plurality of antennas.

Abstract
There is provided a transmission device capable of preventing increase of retransmission information or encoding redundant bit and improving a throughput in a MIMO communication method. In this device, an encoding unit (130) subjects data transmitted from a first transmission antenna (110) and a second transmission antenna (120) each formed by a plurality of antennas, to encoding processing all at once. Modulation units (113, 123) modulate the data encoded by the encoding unit (130) for each of the first and the second transmission antennas (110, 120). Transmission units (115, 125) process the modulated data so that it can be transmitted from the corresponding first and the second antennas (110, 120). A transmission control unit (160) performs transmission control of the data transmitted from the respective antennas (110, 120). When retransmitting data, the transmission control unit (160) retransmits the data transmitted from a transmission antenna having a smaller number of antennas than the first and the second antennas (110, 120).
