Abstract:
1. A method for regulating the transmit power of a transmitter in a radio system, comprising: transmitting data to a receiver in consecutive timeframes via a radio interface; repeatedly transmitting a set value of a quality parameter intended for a receive signal, a first set value being transmitted in a first time frame and a second set value being transmitted in a second time frame-subsequent to the first time frame, the first and second set values being transmitted to the receiver from the transmitter; repeatedly determining an actual value of the quality parameter for the receive signal, the actual value being determined for the second time frame; comparing the actual value of the quality parameter for the second time frame with the first set value of the quality parameter for the first time frame, the comparison producing a result; transferring an item of information relating to the result of the comparison from the receiver to the transmitter; when there is a change between the set value of the first time frame and the set value of the second time frame, determining a correction value at the transmitter based on the change, and correcting the item of information relating to the result using the correction value, the item of information being corrected at the transmitter to produce a power control parameter; and regulating transmit power of the transmitter for a third time frame subsequent to the second time frame, based on power control parameter.
