A radio station (100), transmits a continuous control signal and a discontinuous data signal simultaneously. It receives UP and DOWN power control commands and adjusts its transmit power by in response to the UP power control commands, increasing its transmit power by a power step, in response to the DOWN power control commands, decreasing its transmit power by a power step, in response to initiating transmission of the data signal, increasing the transmit power of the control signal, and in response to terminating transmission of the data signal, decreasing the transmit power of the control signal; In response to initiating or terminating transmission of the data signal, the radio station (100) temporarily modifies its response to the power control commands.
