Methods, apparatus and computer programs are disclosed for controlling the output of a transmission point. One embodiment provides a method for controlling the output of a transmission point for a wireless communications network. The method includes determining an average output power of the transmission point, in a particular direction, over a period of time, comparing the average output power to an output power reference value, and allocating data, to be transmitted by the transmission point in the particular direction to one or more wireless devices, to a pool of radio resources. The pool of radio resources is adjusted as a function of the comparison between the average output power and the output power reference value.
