Abstract:
1. A rate matching method for uplink transmission of a mobile telecommunication system, the method comprising: interleaving turbo-coded bits comprising a first sequence, a second sequence and a third sequence from a turbo encoder at an interleaver; determining rate matching parameters including a number of bits to be punctured or repeated for the second and the third sequences (Ni), an average puncturing or repetition distance (q), 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 in consideration of column positions of the second and third sequences before the interleaving; and performing a rate matching on the second and third sequences by applying the determined rate matching parameters to a rate matching algorithm commonly used for the uplink transmission and a downlink transmission.
