Notes/Equations
  1. This subnetwork is used to generate the data stream of one uplink dedicated physical control channel (DPCCH).
    When GainUnit = Index, the gain of DPCCH is based on DPCCHGainIndex; otherwise it is based on DPCCHGainFactor. TFCIOn and FBIBitsCount determine the slot format of DPCCH.
    The schematic for this subnetwork is shown in the following figure. Input FBIBitsValue is feedback information value of one slot. Input TPCBitsValue is transmit power control (TPC) value of one frame. These two inputs as well as TFCIValue are converted to the bit stream, then multiplexed to one frame of DPCCH. After DPCCH data stream is spread by the spreading code generated by WCDMA3G_OVSF, it is mapped onto the Q-branch and multiplied with the scrambling code generated by WCDMA3G_UpLkScrambler.
