Radio communication system with adjustable output transmission

A primary station for use in a radio communication system, comprising:

• a communication channel between the primary station and a secondary station, wherein the primary station is adapted to determine, from measurements of a time rate of change of received signal to interference ratio received from the secondary station, an optimum rate of adjustment of the output power of the secondary station, selected from one of a plurality of rates of adjustment available to the secondary station, and for communicating said rate of adjustment to the secondary station.

A secondary station for use in a radio communication system, comprising:

• a communication channel between the secondary station and a primary station, wherein the secondary station is adapted to determine, based on measurements of a time rate of change of received signal to interference ratio, an optimum rate of adjustment of the output power of the primary station, selected from one of a plurality of rates of adjustment available to the primary station, and for communicating said rate of adjustment to the primary station.

A method of operating a radio communication system, comprising:

• providing a communication channel between a primary station and a secondary station for transmission of information from one of the primary and secondary stations (the transmitting station) to the other station (the receiving station);
• determining at the receiving station, from measurements of a time rate of change of received signal to interference ratio, an optimum rate of adjustment of the output power of the transmitting station, selected from one of a plurality of rates of adjustment available to the transmitting station;
• and communicating the determined rate of adjustment to the transmitting station, and in response the transmitting station, setting the adjustment rate of its output power.
