Patent ID: 7814390

Claim:
A rate matching method for uplink of a mobile communication system, the method comprising: interleaving turbo-coded bits which consist of a first sequence, a second sequence and a third sequence output from a turbo encoder at an interleaver; determining a total number of bits to be punctured or repeated (ΔN) for the turbo-coded bits, a first number of bits to be punctured or repeated for the second sequence, a second number of bits to be punctured or repeated for the third sequence, and an average puncturing or repetition distance (q), wherein the first number and the second number are determined differently when (ΔN) is an odd number; determining a first shifting parameter for the second sequence and a second shifting parameter for the third sequence, wherein the first and second shifting parameters are determined differently according to a value of (q); and performing a rate matching for each of the second sequence and the third sequence by using the determined first and second numbers and the determined the first and second shifting parameters.
