Multi-layer cyclic redundancy check code in wireless communication system

摘要

A wireless communication device includes a first cyclic redundancy check (CRC) coder configured to generate a first block of CRC parity bits on a transport block, the first CRC coder attaching the first block of CRC parity bits to the transport block, a segmenting entity having an input coupled to the first CRC coder, the segmenting entity configured to segment the transport block into multiple code blocks after attaching, a second CRC coder configured to generate a second block of CRC parity bits on each code block, the second CRC coder attaching a second block of CRC parity bits to each code block, the second block of CRC parity bits attached to each code block is the second block of CRC parity bits generated based on the corresponding code block, the first block of CRC parity bits based on a first generator polynomial D 24 +D 23 +D 18 +D 17 +D 14 +D 11 +D 10 +D 7 +D 6 +D 5 +D 4 +D 3 +D+1 and the second block of CRC parity bits based on a second generator polynomial D 24 + D 23 + D 6 + D 5 + D + 1, and a channel encoder configured to encode each of the code blocks including the attached second block of CRC parity bits.
