Notes/Equations
- 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
- One HS-DPCCH sub-frame contains 30 bits, 10 are HARQ-Ack bits and 20 are CQI bits.
- 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.
