Abstract  Abstract

A hybrid ARQ retransmission method in a communication system wherein data packets consisting of symbols encoded with a forward error correction (FEC) technique prior to transmission 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 transmitted bits of the modulated symbols are reordered over the retransmissions in accordance with the selected redundancy version.
