In a method for optimizing the automatic amplifier setting in radio receivers in which information available in a radio station is utilized in a new manner. A prediction about the behavior of the reception power is to be undertaken in the reception station. To this end, the transmission power control of one station and of the variations to be anticipated as a result thereof are involved in the prediction of the anticipated reception power of the other station. This ensues in such a way that a prediction based on knowledge of the transmission power control data is supplied to the automatic gain control (AGC) of the receiver.

Method for optimizing the automatic amplifier setting in radio receivers

In a method for regulating transmission power control of a mobile station, transmission power control occurs based on a hierarchical control system composed of two levels. Long-term transmission power control of the mobile station occurs in the base station on the upper level, which forms a closed control loop comprising a base station and a mobile station. In addition, a statement about decision authority of the lower level is made in the base station and is communicated to the mobile station. Taking the long-term transmission power identified by the base station and taking the statement about the decision authority of the lower level into consideration, the short-term transmission power of the mobile station is calculated on the lower level, which represents a local control loop implemented in the mobile station.
