## Abstract

Entities implement a phase of communicating data conveyed by a plurality of transport channels, the data of the transport channels 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. A method includes calculating, by one of the entities, the final size, according to the initial size, a first parameter, a second parameter and a maximum payload of the multiplexing frame. The first parameter is an integer relating to a rate matching ratio of the final size to the initial size. The second parameter is a non-dimensional number corresponding to a maximum percentage of bits to be punctured and is predefined before the calculating. The method further includes executing, by the one of the entities, a transformation of the input data block into the output data block.

## Claims

### Claim 1

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 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:
calculating, by one of said plurality of entities, said final size of said output data block, according to said initial size of said input data block, a first parameter, a second parameter and a maximum payload of said at least one multiplexing frame, said first parameter being an integer relating to a rate matching ratio of said final size to said initial size, said second parameter being a non-dimensional number corresponding to a maximum percentage of bits to be punctured and being predefined before said calculating;
executing, by said one of said plurality of entities, a transformation of said input data block of said initial size into said output data block of said final size; and
transmitting, by said one of said plurality of entities, data transformed in the transforming via a physical channel to another of said plurality of entities, referred to as a second entity.

### Claim 2

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.
