Notes/Equations
- This model is used to add CRC bits to each transport block.
- Each firing, one transport format indicator token is consumed at TFIin. This value is used to select the transport block size and transport block set size from the transport format set, as specified by DynTFSet.
- The TFI value is output at TFIout.
