Abstract
Controlling interference in a telecommunications network, in which data are transmitted between mobile devices and base stations in resource blocks, includes, for each of the base stations: allocating resource blocks to one of multiple resource groups, the corresponding resource blocks of each base station being in the same resource group; allocating resource groups to one of multiple transmission power values, the corresponding resource groups of each base station having different transmission power values; and allocating respective ones of the mobile devices to one of the resource groups depending upon a UE characteristic. Interference at a resource block of a resource group of a base station caused by a neighboring base station is detected. In response thereto, an indication of the resource group subject to interference is sent to the neighboring base station and then the transmission power value of said resource group of the neighboring base station is selectively reduced.
