Method for a telecommunication system having a plurality of transport channels that transforms at least one data block size based on a rate matching ratio and a maximum percentage of bits to be punctured

A method for a telecommunication system comprising a plurality of entities implementing a phase of communicating data conveyed by a plurality of transport channels, wherein said plurality of entities comprises at least one sending entity and at least one receiving entity, a phase of communication of said at least one sending entity comprises a plurality of processing procedures specific to said plurality of transport channels, each processing procedure comprises a rate matching and said rate matching executes a transformation of an input block of an initial size into an output block of a final size by at least one of a puncturing and a repetition, said method comprising:

• calculating, by said at least one sending entity, for each of said processing procedures, said final size of said output block as a function of said initial size of said input block on a basis of a criterion, said criterion being dependent on a first parameter that is a non-dimensional number corresponding to a maximum percentage of bits to be punctured, and a second parameter that is an integer relating to a rate matching ratio, said first parameter being predefined before rate matching,
• said rate matching executing said transformation of said input block of said initial size into said output block of said final size by puncturing or repeating some bits of said input block based on a variation between said final size and said initial size;
• and
• transmitting, by said at least one sending entity, data transformed in the rate matching via a physical channel to another of said plurality of entities, referred to as a second entity.
