In accordance with the exemplary embodiments of the invention there is at least a method, apparatus, and executable computer program to perform operations including detecting that a cell in a wireless communication system is able to selectively increase or decrease its transmit power by an amount, where the cell is configured with a transmit power and a parameter that indicates a maximum difference in power change, resulting from a change in transmit power, that can exist between a power change of the cell and a power change of a neighbor cell, examining, at the cell, a signal comprising at least one value received from at least one neighbor cell, based on the examining, determining that a transmit power change is possible, modifying a value associated with the transmit power, and modifying the transmit power of the cell by the modified value, and signaling the modified value to the at least one neighbor cell in the wireless communication system.
