    • In a cellular radio system Transmission Power Control (TPC) power offset is set so that it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC “up” and the number of TPC “down” sent by a radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands. The discarding procedure in the mobile station may also be carried out selectively such that TPC commands that are determined to be unreliable are not discarded but selectively discarded based on how reliable they are determined to be.

    • The present invention relates to a method and an arrangement for controlling downlink power in a multi-carrier communication network system. The communication network system comprises communication network nodes (15) communicating with a plurality of user equipments (18) on uplink (17) and downlink (16) carriers over a radio interface. Downlink transmit power control commands are sent on at least one uplink control channel to support power control for a multiple of downlink carriers. Each transmit power control command is assigned a pre-determined code word known by said user equipment (18) and said communication network node (15) and/or different pre-determined slot formats, known by said user equipment (18) and said communication network node (15), are used to integrate different number of transmit power control command based on the number of used downlink and uplink carriers.
