<p>Provided is a method for retransmitting packet in a Multiple Input Multiple Output (MIMO) system. The method includes: in a receiving block, decoding packets received from a transmitting block and detecting whether an error exists or not in the packets; if the error is detected, transmitting a negative acknowledgement (NACK) signal informing transmission failure of the packets to the transmitting block; calculating channel quality information (CQI) values for transmission-failed packets after performing successive interference cancellation (SIC) with respect to all antenna combinations to retransmit the transmission-failed packets; and selecting an antenna combination having CQI values of the transmission-failed packets which are equal to or greater than respective initial CQI values of the transmission-failed packets among the antenna combinations, and transmitting information of the selected antenna combination to the transmitting block.</p>
