The correct detection of DPCCH channels reduces uplink interference.
It is alternatively possible to adjust data channel according to the sir target value of the sir target value of data channel and control channel
PO is adjusted the sir target value of data channel according to the adjustment amount of the PO of data channel.Specifically, when control channel

The sir target value c of power control can be selected as the higher value in a and b.Assuming that a>B, then c=a.Illustrate the SIR mesh of external circule power control at this time
Scale value is bigger than normal, optionally, if（c-b）The quantization threshold of POs of the dB more than E-DPDCH, then the PO of E-DPDCH can be subtracted
Several small amount ranks（It is set as xdB, wherein x is less than or equal to（c-b）dB）, according to adjustment amount, that is, several amounts rank x reduced,
The sir target value for adjusting E-DPDCH, if the Sir desired values of the E-DPDCH after adjusting are b+x, then final external circule power control
Sir target value should be the big value in a and b+x., whereas if b>A illustrates that the transmission power of HS-DPCCH has redundancy,
If（c-a）DB is more than the PO quantization thresholds of HS-DPCCH, can reduce several amount ranks of HS-DPCCH（It is set as y（dB）,
Middle y（dB）It is less than or equal to（c-b）dB）, according to adjustment amount, that is, several amounts rank y reduced adjusts the SIR mesh of HS-DPCCH
Scale value, if the sir target value of the HS-DPCCH after adjusting is a+y, then the Sir desired values of final external circule power control should be a+y
With the higher value in b.
