A method for a telecommunication system, said telecommunication system comprising a plurality of entities implementing a phase of communicating data conveyed by a plurality of transport channels, said data of said plurality of transport channels being multiplexed into at least one multiplexing frame, said data being rate-matched by transforming an input data block of an initial size into an output data block of a final size, said method comprising:
- determining, by one of said plurality of entities, a first parameter, said first parameter being an integer relating to a rate matching ratio of said final size to said initial size;
- transmitting said first parameter from said one of said plurality of entities to another of said plurality of entities;
- receiving, by said another of said plurality of entities, said first parameter transmitted by said one of said plurality of entities;
- and
- calculating, by said another of said plurality of entities, said final size of said output data block, according to said initial size of said input data block, said first parameter, a second parameter and a maximum payload of said at least one multiplexing frame, said second parameter being a non-dimensional number corresponding to a maximum percentage of bits to be punctured, said first parameter being selected from a first range, and said second parameter being selected from a second range that is different from said first range.
