ABSTRACT:
A multi-antenna communication method capable of improving the retransmission performance in a multi-antenna transmission. In this method, firstly, the reception quality of a substream to be retransmitted is acquired (Step401). Then, it is determined for the substream whether any transmission antennas, which satisfy a target value related to the foregoing reception quality when they are used for the retransmission, are existent among the transmission antennas that are candidate antennas to be used for there transmission (Step405). Then, if there exist any transmission antennas satisfying the target value, a transmission antenna to which the poorest channel characteristic corresponds is selected from among those transmission antennas satisfying the target value, and the selected transmission antenna is designated as an antenna to be used for retransmitting the foregoing substream (Step406). If there exist no transmission antennas that satisfy the target value, then a transmission antenna to which the best channel characteristic corresponds is selected from among the foregoing candidate transmission antennas, and the selected transmission antenna is designated as an antenna to be used for retransmitting the foregoing substream (Step407).
