Abstract
Power control in a base to mobile link of a mobile radio system is effected by measuring the carrier/interference ratio at each mobile station and transmitting information thereof, usually in terms of the inverse of that ratio, to the base station. Power is shared between the traffic channels which are active by assigning fractions thereto utilizing a power control factor as the coefficient typical of the channel and depending on the ratios for all of the stations, on the number of active channels, on whether or not there have been variations in the active channels relative to a preceding interval and on the power assigned to the channel in the preceding interval.
