Abstract: An ARQ(Automatic Repeat reQuest) apparatus in a MIMO(Multi Input Multi Output) system and a method thereof are provided to minimize the retransmission data error rate through a proper ARQ operation method by conducting weight-based descendent sorting and ascendent sorting respectively for error packets and antennas, allocating the antennas to the error packets in the sorted order, and transmitting the allocation information to a transmitting block so as to select an antenna for retransmission. A receiving block detects the packets received at a time of "t", and checks whether the packets have errors(301). The receiving block checks whether every antenna has the same weight(303). If not, the receiving block carries out ascendent sorting for antennas and descendent sorting for error packets according to their weights(305). The receiving block allocates the antennas to the error packets in the sorted order(307). The receiving block reconfigures the weights of the sorted error packets and antennas as interval information "Ik"(309). The receiving block replaces the antennas allocated to error packets with other antennas according to Ik types(311). Then the receiving block transmits information for the retransmission antennas allocated to the error packets to a transmitting block(313) Afterwards, the receiving block receives retransmission packets and initial transmission packets from the transmitting block and calculates weights for the received packets(315).
