Abstract
An automatic repeat request control system in an OFDM-MIMO communication system. In this system, the ACK / NACK output unit (320) of the receiver sends positive or negative feedback information to the transmitter based on the result of the cyclic redundancy check. The error data stream detection unit (310) of the transmitter identifies the data stream that needs to be retransmitted based on the feedback information, and the retransmission mode selection unit (312) (a) determines the data to be retransmitted last time. (B) A mode in which new data is transmitted using an antenna that does not request data retransmission at the same time as (b). A mode in which new data is transmitted, (c) a mode in which data is retransmitted using STBC on an antenna that does not require retransmission, and (d) a mode in which data is retransmitted using STBC on all available antennas. Select the retransmission mode from
