Notes/Equations
- This subnetwork encodes the HARQ-Ack and CQI message and multiplexes the coded bits stream as a HS-DPCCH sub-frame.
- The schematic for this subnetwork is shown in the following figure.
3GPPFDD_HS_DPCCH_Encoder Schematic
- One HS-DPCCH sub-frame contains 30 bits. Each HARQ-Ack bit is repeated 10 times [2]. The 5 bits of CQI information are protected by a (5, 20) coding scheme [2]; the 30 bits are used to form the HS-DPCCH frame.
- Each firing: if CQI_Type is Binary, 5 bits will be consumed at CQI; if CQI_Type is Decimal, 1 decimal number will be consumed at CQI and converted to 5 binary bits.
