Abstract

According to the inventive method for adjusting transmitter power, radio stations are interlinked via a radio interface, which is organised according to a TDD transmission method with several time slots per frame. Said time slots can be allocated to different connections. Emissions from a first radio station are received by a second radio station in a control loop-type arrangement, correction values are determined based on the emissions received and the correction values are conveyed to the first radio station where they are taken into account in adjusting the transmitter power for subsequent emissions. The invention also provides that the first radio station receives emissions from the second radio station in at least two time slots of the frame, that the at least two emissions are compared with each other and that the result of this comparison is taken into account in adjusting the transmitter power.
