A method for controlling transmission power of shared control channel for high speed downlink shared channel (HS-SCCH) in an UMTS system adopting a high speed downlink packet access (HSDPA) is disclosed in which a power offset value for power control of HS-SCCH is determined by a serving radio network controller and transmitted as a control frame or message type to a base station. A first PO field for transmitting a PO value for non-handover or soft handover of a dedicated physical control channel, a second PO field for transmitting a PO value used for the primary cell and a third PO field for transmitting a PO value used for the non-primary cell are selectively implemented in the control frame or message type, so that the transmission power of HS-SCCH can be suitably controlled according to changes in environment or circumstances of the radio link.
A control information transmitting method of a mobile communication system comprising:
A control information transmitting method in a mobile communication system (UMTS) in which transmission power of a shared control channel for HS-DSCH (HS-SCCH) transmitted from a base station to a UE is determined by using a power offset (PO) value relative to a dedicated physical control channel (DPCCH),
A control information transmitting method of a universal mobile communication system (UMTS) in which transmission power of a shared control channel for HS-DSCH (HS-SCCH) transmitted from a base station to a UE is determined by a power offset (PO) value relative to a dedicated physical control channel (DPCCH),
