Abstract: The present invention relates to an adaptive automatic repeat-request apparatus and method for an MIMO system including a transmitter and a receiver. The apparatus comprises an adaptive retransmission component located at the transmitter. The adaptive retransmission component uses a special frame structure that divides the transmission data in a frame into several sections according to the number of transmission antennas, and adds an individual error detecting code within each section. The transmission data are sent to the receiver through the several antennas. The receiver responds to the adaptive retransmission component with feedback information of an acknowledgement or negative acknowledgement signal, and detected signal strength of data for each transmission antenna. After receiving the signal strength of transmission data, the retransmission signal vector for error data is determined.
