Method and apparatus for providing adaptive cyclic redundancy check computation

摘要

A method and apparatus for providing adaptive cyclic redundancy check (CRC) computation is disclosed. A transport block size is determined. Transport block (TB) CRC bits are computed with a first CRC generator when the TB size is less than or equal to a predetermined threshold. TB CRC bits are computed with a second CRC generator when the transport block size is greater than the predetermined threshold. When the TB is greater than the predetermined threshold, the TB is segmented into code blocks (CBs) and CB CRC bits are computed with the first CRC generator. A method and apparatus for handling adaptively cyclic redundancy check (CRC) encoded transport blocks (TBs) is also disclosed. A TB is received. The TB is CRC checked based on a first CRC generator when the TB size is less than or equal to a predetermined threshold. Code blocks of the TB are CRC checked based on the first CRC generator when the TB size is greater than the predetermined threshold. When the TB size is greater than the predetermined threshold, the code blocks are concatenated, and the TB is CRC checked based on a second CRC generator.
