Abstract  Abstract

in a cellular wireless packet switched data transmission system control of the transmission power comprises closed loop control and open-loop control. a control signal (30 31) for a long time before forming the connection and between the packet pause period the measuring terminal device transmitted by the base station and the signal power (R0) is compared with the target level (t0). the base station also reports in the control signal transmission power the terminal device sets the power to its transmit power accordingly. or the transmission link quality (RXOUAL) is measured in the confirmation information of the packet the transmitting device to change its transmit power so that the quality control on a certain target level.
