Abstract: The invention relates to a method for regulating the transmission power in a radio communications system, in particular, in a mobile telecommunication system (UMTS). In said system, a transmission signal is sent from a transmitter (MS) and evaluated by a receiver (BS), in order to generate power regulation commands dependent on said process for regulating the transmission power of the transmitter (MS), and to transmit said commands to the transmitter (MS). To this end, an estimated value (&dgr;) for the transmission power regulation of the transmitter (MS) is used after a transmission gap, whereby a power regulation command, which results in a predetermined transmission power threshold being attained, exceeded or not attained, is taken into consideration during the determination of the estimated value (&dgr;).
