ABSTRACT:
The invention relates to a method of controlling, in a cellular mobile radio communication system, the output power of radio signals transmitted from a transmitter to a receiver located in the same cell as the transmitter. The method comprises controlling the output power of the transmitter in dependence of a parameter, that is characteristic of the distance between transmitter and receiver, to approximately follow, from a predetermined maximum output power that is transmitted when the distance between the transmitter and receiver is the maximum within the cell, a first function that monotonically decreases with decreasing distance and approaches a predetermined minimum output power as the distance approaches zero, so that the power of the transmitted radio signals as received by the receiver from a minimum received power, that is received when the distance between transmitter and receiver is the maximum within the cell, approximately follows a second function that monotonically increases with decreasing distance and approaches a maximum received power as the distance approaches zero.
