The present invention relates to a method and an arrangement of obtaining efficient power control during soft handover in a communication network system when a user equipment (18) is in communication with two or more radio base stations (15a, 15b) over a radio interface on downlink (17) and uplink (16) channels. Transmit power control (TPC) commands are received from said two or more radio base stations (15a, 15b) on said downlink channels (17). Said received transmit power control commands are analysed and a power offset on said uplink channels (16) is adjusted based on said analysed transmit power control commands.
