The input bit sequence for the code block concatenation block are the sequences 
, for 
and 
, where 
is the number of rate matched bits for the 
-th code block. The output bit sequence from the code block concatenation block is the sequence 
for 
.
The code block concatenation consists of sequentially concatenating the rate matching outputs for the different code blocks. Therefore,
