ABSTRACT:
A system and method are provided for setting gain factors for dedicated physical channels in a mobile communication system supporting E-DCH service. If the E-DCH is established without the legacy DCH, the UE sets a gain factor for a DPCCH related to the DCH to a predetermined constant and calculates gain factors for dedicated physical channels related to the E-DCH using the gain factor of the DPCCH. In another embodiment of the present invention, if the E-DCH is established without the legacy DCH, the RNC sets a gain factor for a DPCCH related to a virtual DCH to a predetermined constant and sends channel configuration information including the gain factor to the UE.
