ABSTRACT:
A method for segmenting an information word into code blocks in a mobile communication system. The method includes setting a number C of code blocks to a minimum integer not less than a value obtained by dividing X by Z; when sizes K of all code blocks are determined to be equal when a length X of the information word is greater than a maximum length Z of each code block, determining a minimum integer value T not less than a value obtained by dividing a size of the information word by a number of code blocks, and determining, as K, a maximum value most approaching the value T among the values based on which a size of the code block can be set in units of eight bits; and generating a code block by inserting filler bits into a specific code block when a value obtained by multiplying K by C is greater than X.
