Abstract:
1. A method for a first radio base station of a mobile telecommunication network for controlling power of a Dedicated Physical Control Channel, DPCCH, used by a user equipment, UE, connected to said first radio base station and to a further radio base station, wherein the UE is configured to transmit data on one or several Dedicated Physical Data Channels, E-DPDCH, and to transmit reference information for channel estimation on a DPCCH, and the method comprises the steps of: using a first SIR target for the DPCCH power used by said UE, detecting a change of the UE data transmission rate on the E-DPDCH, and adjusting the first SIR target for the DPCCH power to a second SIR target for the DPCCH power used by the UE based on a pre-determined mapping between a new UE data transmission rate on the E-DPDCH and the second SIR target for the DPCCH power, wherein the adjusting step comprises the steps of: wherein the estimating and mapping steps comprise the steps of: wherein the first radio base station is acting as a non-serving radio base station to said UE.
