Abstract
A method and apparatus for code block division are provided. The method may include the following acts. A reference information block length of a code block is determined according to an obtained division related parameter. A maximum information block length is determined according to the reference information block length and a hardware parameter. A Transport Block (TB) having a length greater than the maximum information block length may be divided into two or more code blocks according to the obtained division related parameter, the hardware parameter and the determined maximum information block length. An information length after code block division is less than the determined maximum information block length.
