Method and apparutus for retrnansmission mode selection in a mimo communication system

The present invention, multiple-input multiple-output communications in the resend mode selection method of a receiving apparatus in the system, an initial transmission of m from the transmitter (where, m is an integer of 2 or greater), the method comprising the steps of receiving a stream, decoding the m pieces of stream channel If the later, the method comprising the steps of: checking the channel-decoded m streams each error has occurred or not, a result of the checking error to more than one stream of said m number of streams has occurred, two or more occurred the error in the transmitter the information indicating the process and the selected the retransmission mode is selected the retransmission mode to be used for the stream comprises the step of transmitting to the transmitter.
