Dear Community,


According to 3gpp 38.212 5.4.2 Rate matching for LDPC, the Nref is calculated according Figure 1:
Nref= floor(TBS_LBRM/(R_LBRM*C)), and "C" is the number of code blocks of the transport bolck neither the TBS_LBRM.


But according to the srsRAN function sch_nr_Nref as Figure 2:
Nref= ceil(TBS_LBRM/(R_LBRM*C)), and "C" is the  number of code blocks of TBS_LBRM.


Please confirm is there some misunderstand? 
Thanks~
