Abstract:
1. A method in a communication system, comprising the steps of: sending at a first radio network entity a transmission power control signal to a mobile radio to control a power level at which the mobile radio transmits data units over the communications channel based on a target value; detecting at the first radio network entity one or more errors in one or more data units received from the mobile radio and requesting retransmission of one or more data units; and, providing information associated with the requested retransmission to a second radio network entity for generating a revised target value based on the received information in the second radio network entity; wherein when the first radio network entity processes one or more bit maps associated with the communication indicating a number of decoding failures for one or more received data units and sends processed information resulting from the processing to the second radio network entity, wherein the processed information is less data than the one or more bit maps.
