ABSTRACT:
A slave station and a method of regulating the transmission power a master station are described, which permit an estimate of the signal/interference ratio in a transmission system without sending a pilot sequence, the transmission power being regulated as a function of an estimate of the signal/interference ratio. In a transmission system, in particular a CDMA transmission system, useful signals assigned to different communicating subscribers are separated by orthogonal codes. A useful signal assigned to one communicating subscriber is derived by using one of the codes from a signal received at least in the slave station from the master station and is compared as a reference signal with the received signal to estimate the signal/interference ratio.
