Abstract:
1. A method for transmitting by a radio network controller (RNC) a power offset for controlling transmission power of an uplink high-speed dedicated physical control channel (HS-DPCCH) when a user equipment (UE) enters a handover region, in a mobile communication system including the RNC, a Node B connected to the RNC, and the UE located in one of at least two cell areas occupied by the Node B, wherein the Node B transmits data to the UE over a high-speed downlink shared channel (HS-DSCH) and the UE transmits a response information indicating reception status of the data to the Node B over the uplink HS-DPCCH, the method comprising the steps of: informing the UE of a power offset; determining a transmission power increment of the uplink HS-DPCCH, if it is determined that the UE is located in the handover region; informing the Node B of the power offset; and determining by the Node B a threshold value for determining the response information received from the UE, depending on the power offset.
