Notes/Equations
  1. This model implements downlink physical channel de-mapping. Please refer to [1] for downlink physical channel mapping processing.
  2. This model fires once per radio frame. Each firing, this model receives data blocks of each physical channel at multiple input pin DataIn, and receives slot TFCI at pin TFCIin. This model then collects the necessary bits from each physical channel.
  3. DataIn will input data of one radio frame; the previous model will output data blocks of one slot. This means the previous model will fire 15 times when this model fires once. Note that TFCI will be generated once per radio frame, so TFCIin will input one data each firing.
