Transport block size

The output of a coding chain is a codeword. 5G supports transmission of up to 8 layers to a single user on the downlink. This means that there can be up to eight streams transmitted in parallel.

for code block segmentation used on LTE-Advanced channel coding physical layer (PHY) is presented in this paper. Code block segmentation is a generic procedure which is commonly applied before turbo encoding . Its main function is to fragment a large transport block into smaller code blocks.

Transport Block CRC Attachment A cyclic redundancy check (CRC) is used for error detection in transport blocks . The entire transport block is used to calculate the CRC parity bits. The transport block is divided by a cyclic generator polynomial, described as g C R C 24 A in section 5.1.
