1. An apparatus, comprising:
at least one processor; and
at least one non-transitory memory storing instructions, that when executed by the at least one processor, cause the apparatus to:
control radio transmission in cells of a cellular communication system by causing the apparatus to:
determine a set of cells having a spatially overlapping coverage area in a sector, wherein the set of cells comprises at least a first cell and a second cell;
determine a maximum total transmission power level for the sector;
determine a priority of each cell in the set of cells such that the first cell is prioritized over the second cell; and
allocate, on the basis of the maximum total transmission power level and said priorities, to each cell in the set of cells a parameter indicating a maximum transmission power level in the respective cell,
wherein the parameter is a multiplication factor applied to a time-averaged maximum transmission power in order to obtain its actual maximum value from its cumulative distribution function, and
wherein said allocating is performed such that a smaller power reduction from a maximum transmission power is allowed for the first cell than for the second cell.
