Abstract

A method and communication device are provided for matching the bit rate of a bit stream to be transmitted in a communication system. For bit rate matching in a communication system the bits of a bit stream are punctured or repeated so that for a specific number (N) of consecutive bits (x) of the bit stream to be transmitted, the sum of the importances (w) of the bit stream which features the relevant bits (x) of the bit stream for a recovery of a message containing the relevant bit are in a specific relationship to the sum of the reliabilities (v) of the corresponding bits actually used for transmission (y) with which these bits after execution of bit rate matching can transfer a specific information content.
