Abstract
A wireless communication method by which unnecessary retransmission request is suppressed and feedback information is reduced at the same time in a MIMO communication system. The wireless communication method is provided for transmitting signals by using a plurality of antennas, and has a step of applicably selecting the group configuration of the antennas, and a step of adding data to be used for error detection to a signal to be transmitted by using the antennas, by following the results of the selection.
