Abstract: PURPOSE: A transceiving method for re-transmitting packets in a mobile communication system and a device therefor are provided to reverse bits of packets upon re-transmission, so as to map the re-transmitted bits to symbols in an area different from an area of initial transmission. CONSTITUTION: A CRC(Cyclic Redundancy Check) adder adds CRC bits for error check on packet data to be transmitted(602). A channel encoder encodes the packet data on which the CRC bits are added(604). A rate matching unit performs rate matching for encoding bits from the channel encoder(606). The interleaver interleaves and outputs the rate matched encoding bits(608). A reverse controller decides whether the packets are initially transmitted or re-transmitted(610). If initially transmitted, the reverse controller bypasses the encoding bits for supply to a modulator. The modulator modulates the encoding bits(616), and the modulated encoding bits are transmitted(618). If the packets are not initially transmitted in the step 610, the reverse controller discriminates whether the packets are re-transmitted odd times(612). If not, the reverse controller bypasses the encoding bits and the steps 616 and 618 are performed.
