Abstract:
A method for transmitting a sequence of information bits and sequences of parity bits in an HARQ (Hybrid Automatic Repeat Request) transmission system including a turbo encoder for receiving a L input information bits and generating a coded data, the L information bits and M (&gE;2) sequences of L parity bits for the input information bits, the method comprising the steps of:transmitting the L information bits and part of sequences of the parity bits determined by one of two integers closer to (N1âˆ’L)/M where N1 indicates a number of transmission bits given when an initial transmission code rate of the turbo encoder is below 1 during initial transmission; and at a receiver's retransmission request due to failure to receive the information bits transmitted during the initial transmission, transmitting part of sequences of parity bits determined by one of two integers closer to N2/M where N2 indicates a number of the transmission bits given when a retransmission code rate of the turbo encoder is below 1.
