Notes/Equations
  1. This subnetwork de-multiplexes coded HARQ-Ack and CQI bits from the HS-DPCCH subframe and decodes the coded bits stream as HARQ-Ack and CQI messages.
    The schematic for this subnetwork is shown in the following figure.

    3GPPFDD_HS_DPCCH_Decoder Schematic
  2. One HS-DPCCH sub-frame contains 30 bits, 10 are HARQ-Ack bits and 20 are CQI bits.
  3. Each firing: if CQI_Type is Binary, 5 bits will be generated at CQI; if CQI_Type is Decimal, 1 decimal number in the range of [1,31] will be generated at CQI.
