Method and apparatus for receiving and transmitting using mimo multiple hybrid arq scheme

PURPOSE: A transmitting/receiving method which uses a multi-antenna multi-hybrid automatic repetition request technique and an apparatus thereof are provided to transmit a sub-packet which is to be retransmitted in a symbol unit when a partial retransmission process is performed due to a transmission error, thereby reducing delay time due to the retransmission process. CONSTITUTION: A transmission apparatus receives a retransmission request with respect to one or more sub-packets(110). The transmission apparatus determines the number of multiple antennas and the one or more sub-packets(120). The transmission apparatus assigns symbols included in a specific sub-packet among the one or more sub-packets to two or more antennas(130). The transmission apparatus retransmits the one or more sub-packets through the multiple antennas(140). The transmission apparatus assigns symbols included in a first sub-packet to the two or more antennas(150). The transmission apparatus assigns a part of symbols included in a second sub-packet to the two or more antennas and other antennas(160). The transmission apparatus assigns the rest of the symbols included in the second sub-packet to one antenna among the two or more antennas(170).
