Claim:
1. A method, in a first cell of a communication network, for performing inter cell interference coordination between the first cell and a second cell of the communication network, wherein at least the first cell comprises a plurality of distributed transmission points, the method comprising individually controlling the transmit power of one or more of the plurality of distributed transmission points within the first cell, wherein said individually controlling the transmit power comprises: determining a two-dimensional power-reduction pattern indicating which subframes, if any, of each transmission point of the first cell are to be transmitted at a reduced power, the two-dimensional power-reduction pattern comprising power-reduction patterns for each of a plurality of the transmission points of the cell; wherein the power-reduction pattern for a particular transmission point is individual to that transmission point, and may be the same as or differ from a power-reduction pattern for one or more other transmission points in the first cell.
