Initial Power is set in the same way as open Loop Power control of DCH & there is no further power control on HSDPA Shared Channel HS-DSCH. The Channel Rate is controlled by adaptive modulation & coding formats.
The principles and functionality of the power control for the HSDPA associated dedicated channels are the same as for the DPCH power control.
