A method of controlling interference in a telecommunications network comprising a plurality of base stations (eNB A and eNB B) and a plurality of mobile devices, and in which data are transmitted between each mobile device and base station in resource blocks. The method includes, for each of said base stations: - allocating respective ones of said resource blocks to one of a plurality of resource groups, the corresponding resource blocks of each base station being in the same resource group; - allocating respective ones of said resource groups to one of a plurality of transmission power values, the corresponding resource groups of each base station having different ones of said transmission power values; and - allocating respective ones of said mobile devices to one of the plurality of resource groups in dependence upon a characteristic of the UE. Interference 32 at a resource block of a resource group of one of said base stations (eNB A) caused by a neighbouring one of said base stations (eNB B) is detected. In response to the detection, an indication of the resource group subject to interference is send to said neighbouring base station. In response to said indication, the transmission power value of said resource group of said neighbouring base station is selectively reduced. |
