The invention relates to a radio base station (13) for handling Outer Loop Power Control of a user equipment (12) in a radio communications network of a multiple cell (10,11) High Speed Uplink Packet Access configuration: The user equipment (12) is connected to at least two cells (10,11) using at least two carriers, one cell per carrier, wherein the radio base station (13) reports number of hybrid automatic repeat requests of the two or more carriers to a network control node (14). The radio base station (13) and the network control node (14) are comprised in the radio communications network. The radio base station determines (401) a number of hybrid automatic repeat requests over a first carrier of the at least two or more carriers, and signals (402) a user plane frame to the network control node (14). The user plane frame comprises the determined number of hybrid automatic repeat requests and an identity associated to the first carrier, enabling the network control node (14) to control an Outer Loop Power Control parameter to be used in an Outer Loop Power Control process for the first carrier.
