Abstract
The invention relates to a method for controlling the emission power of an especially mobile emission station (MT). The aim of the invention is to keep the emission power to a minimum. To this end, a reception station (AP) which receives the emitted data (c1) as reception data (c1*) determines the measuring values of the same, and sends them to the emission station (MT) via a secure connection (DL) which is not, or is only slightly, affected by disturbances. The measuring values (c1*) depend on the data (c1) transferred by the signal.
Claims13
A method for controlling the emission power, comprising:
- transmitting a signal for transmission of data from a sending station to a receiving station;
- determining a measured value of the signal received at a receiving station, wherein the received signal depends on the data transmitted by the signal, and the measured value is a reception power amplitude value of the data received by the receiving station with the signal;
- and
- transmitting the received signal from the receiving station to a sending station, wherein the measured value of the received signal is transmitted as control information for controlling an emission power, and wherein the sending station, after receiving a previous measured value of previously sent data, sends correction data for the previously sent data to the receiving station which depends on the relevant measured value.
A receiving station for a communications system, comprising:
- a device for determining a measured value of a received signal which depends on the data transmitted by the signal, wherein the measured value is a reception power amplitude value of the data received with the signal;
- a device for sending the measured value to a station sending the signal as control information for controlling the emission power of the sending station;
- and
- a device for receiving correction data sent from the sending station for the data sent previously, with the correction data depending on the relevant measured value.
A sending station for a communications system, comprising:
- a send device for transmitting data by means of a signal to a receiving station;
- a receive device for receiving a measured value of the signal received by the receiving station which is dependent on the data transmitted by the signal, wherein the measured value is a reception power amplitude value of the data received with the signal;
- a device for controlling the emission power which takes account of the measured value as control information when controlling the emission power;
- and
- a device for sending correction data for previously transmitted data, with the correction data depending on the measured value.
