enum

 

† The range for each element must be in [0:164480]; elements shall be paired integers; the first of the pair is the transport block size; the second one is the transport block set size; the second shall be multiple of the first.

Notes/Equations
  1. This model is used to add CRC bits to each transport block.
  2. 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.
  3. The TFI value is output at TFIout.
