38.2123GPPMultiplexing and channel codingNRRelease 17TS
The bits input to the code block segmentation are denoted by where is the number of bits in the transport block (including CRC).
Code block segmentation and code block CRC attachment are performed according to Clause 5.2.2.
The bits after code block segmentation are denoted by, where is the code block number and is the number of bits for code block number according to Clause 5.2.2.
When the value of numberOfSlotsTBoMS in the row indicated by the Time domain resource assignment field in DCI is larger than 1, the value of B is no larger than 3840 if and no larger than 8448 otherwise, where coding rate is indicated by the MCS index according to Clause 6.1.4.1 in [6, TS 38.214].
