摘要： A wireless communication device (200) including a first CRC coder that generates a first block of CRC parity bits on a transport block and associates the first block of CRC parity bits with the transport block, a segmenting entity that segments the transport blocks into multiple code blocks after associating, and a second coder that generates a second block of CRC parity bits on each code block and associates a second block of CRC parity bits with each code block. The first and second blocks of CRC parity bits are based on first and second generator polynomials. In one embodiment, the first and second generator polynomials are different. In another embodiment, the generator polynomials are the same and the transport block is interleaved before segmenting or the code block are interleaved before encoding with the second block of CRC parity bits.

摘要： A communication device is disclosed. The device is configured to generate a first block of first cyclic redundancy check (CRC) parity bits on a transport block wherein the first block of CRC parity bits is based on a first generator polynomial, to attach the first block of CRC parity bits to the transport block and to segment the transport block into multiple code blocks. The processor is also configured to generate a second block of CRC parity bits on each code block wherein each of the second blocks of CRC parity bits is based on a second generator polynomial that is different than the first generator polynomial. The first and second generator polynomials have a common degree. A second block of CRC parity bits is attached to each code block, and the code blocks are concatenated after channel encoding.

摘要： A wireless communication transmitter (200) configured to segment a transport block into C segments, encode each segment into a set of encoded bits, determine, for γ encoded segments, a subset of size M0′ of encoded bits for each encoded segment and for C−γ encoded segments, a subset of size M1′ of encoded bits for each encoded segment, wherein the subset sizes M0′ and M1′ differ at most by P bits, where P is a product of a modulation order and a number of transmission layers over which the transport block is transmitted. The selected subsets of encoded bits are concatenated and grouped to form modulation symbols of the modulation order.
