Abstract
The present invention discloses a method in a network node (310, 610) for improving radio network characteristics in a wireless communications network (300, 600) comprising M cells. The method forms at least a first subgroup SC of cells comprising K cells, where K<=M, for coordinated transmission and/or reception between the cells. The network node (310, 610) determines (410, 730) at least one weight aij associated with a first cell Ci and a second cell Cj in the network. The weight a, indicates a radio network characteristic dependent on the cells Ci and Cj. The network node (310, 610) forms (470) the subgroup SC of cells by selecting at most K cells from the M cells, in such a way that a function of the weights aij for each cell Ci and Cj in the subgroup SC is approximately maximized. The network node (310, 610) sends (480) a message to each cell Ck in the subgroup SC, relating said cell Ck to said subgroup SC.
