Abstract:
1. A method in a sending node for generating adjustment commands, for adjusting the transmission power of radio signals sent to a receiving node over at least a data channel and a control channel, the adjustment is performed by adjusting a gain factor, which gain factor is associated with the relation between a first transmission power level of the data channel and a second transmission power level of the control channel, the method comprising: obtaining a first quality value associated with the data channel, by receiving one or more acknowledgement (ACK) or non-acknowledgement (NACK), sent from the receiving node, indicating that the signal, previously has been received correctly or erroneously, respectively, obtaining a second quality value associated with the control channel; determining a first difference between the obtained first quality value and a first quality target value associated with the data channel, determining a second difference between the obtained second quality value and a second quality target value associated with the control channel, adjusting the gain factor based on the first difference and the second difference.
