Notes/Equations
  1. This model is used to generate TFI sets and TFCI, given transport format combination set (TFCS) array. TFSetSizeArray is an array of allowed TFCS. For example, if there are three transport channels, TrCHNum = 3. The allowed TFCS is (TF0, TF0, TF1), (TF1, TF0, TF1), (TF1, TF1, TF0)..., TFSetSizeArray should be set as "0 0 1, 1 0 1, 1 1 0,...". Section 6 of [2] gives some examples of TFCS.
  2. At each maximum TTI of TTIArray, a random set of transport format combinations is selected. The TFIs and TFCI are output at each frame (10 msec).
