Patent ID: 7606212

Claim:
A method of setting gain factors for dedicated physical channels in a mobile communication system, comprising the steps of: determining, in a user equipment (UE), from channel configuration information whether a dedicated physical data channel (DPDCH) to which a legacy dedicated channel (DCH) is mapped is configured; if the DPDCH is configured, setting a gain factor representing the transmit power of a dedicated physical control channel (DPCCH) related to the DPDCH according to the TFC of the DCH set by a radio network controller (RNC) in the UE; if the DPDCH is not configured, setting the gain factor representing the transmit power of the DPCCH to a predetermined constant in the UE; and calculating, in the UE, a gain factor representing the transmit power of at least one dedicated physical channel using the gain factor of the DPCCH.
