## Abstract

A method is for entities implementing a phase of communicating data conveyed by a plurality of transport channels, the data being multiplexed into at least one multiplexing frame. The data is rate-matched by transforming an input data block of an initial size into an output data block of a final size. The method includes determining a first parameter, which is an integer, and transmitting the first parameter from one of the entities to another of the entities. The method also includes calculating the final size, according to the initial size, the first parameter, a second parameter and a maximum payload of the multiplexing frame. The second parameter is a non-dimensional number corresponding to a maximum percentage of bits to be punctured. The first parameter is selected from a first range, and the second parameter is selected from a second range that is different from the first range.
