摘要： An ARQ retransmission method in a communication system, wherein data packets comprising modulation symbols are retransmitted based on an automatic repeat request and subsequently combined with previously received data packets, the symbols of said data packets being modulated by a mapping unit employing a predetermined signal constellation. The retransmitted data packets being retransmitted in form of a selected one of a plurality of different redundancy versions. According to the invention, the bits to be transmitted are reordered prior to modulation over the retransmissions in accordance with the selected redundancy version.
