Abstract:
1. A method for data rate matching, the method comprising the steps of: distributing data to be transmitted in the form of bits via a first interleaver to a set of K frames; carrying out a puncturing or repetition method for data rate matching after interleaving; and varying a distance between punctured or repeated bits with regard to the sequence of the bits before the first interleaver, for puncturing or repeating the same number of bits in each frame, with the separation being defined by the following relationship: q−1≦distance≦q+1cd(q,K)+1, where mean puncturing distance is q:=(└N 1cd(q, K):=highest common denominator of q and K, wherein a puncturing or repetition process is carried out in such a manner that the puncturing or repetition pattern used within a frame is also shifted and used within further frames in the set of frames, and wherein punctured or repeated bits which are adjacent to the sequence of bits before the first interleaver are obtained by a method which comprises the steps of:
