Abstract:
1. A method of controlling interference in a telecommunications network comprising a plurality of base stations and a plurality of mobile devices, and in which data are transmitted between each mobile device and base station in resource blocks, the method comprising: for each of said base stations, allocating respective ones of said resource blocks to one of a plurality of resource groups such that each resource group comprises a plurality of resource blocks, the corresponding resource blocks of each base station being in the same resource group; for each of said base stations, allocating each one 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; for each of said base stations, allocating each one of said mobile devices to one of the plurality of resource groups in dependence upon a characteristic of the mobile device; detecting interference at a resource block of a first resource group of one of said base stations caused by a neighbouring one of said base stations; in response to said detecting, sending to said neighbouring base station an indication of the first resource group subject to interference; and in response to said indication, selectively reducing the transmission power value of a second resource group of said neighbouring base station.
