Claim Text:
1. A method for transmitting data in a mobile communication system, comprising the steps of: encoding a data bit stream by an encoder; determining k for each of the bits included in the encoded data bit steam, where k=m mod 4, and m is an index of each of the bits configured in the encoded data bit stream; inputting bits corresponding to k=0 or 1 from the encoded data bit stream to a first interleave unit; inputting bits corresponding to k=2 or 3 from the encoded data bit stream to a second interleave unit; interleaving the bits corresponding to k=0 or 1 by the first interleave unit to output an n-th bit and an n+1-th bit as a result of the interleaving by the first interleave unit; interleaving the bits corresponding to k=2 or 3 by the second interleave unit to output an n+2-th bit and an n+3-th bit, in order, as a result of the interleaving by the second interleave unit; and generating a modulation symbol with the n-th bit and the n+1-th bit obtained from the first interleave unit, and with the n+2-th bit and the n+3-th bit obtained from the second interleave unit, using a high-order modulation scheme.
