Abstract
In a method of controlling downlink transmitting power and antenna coverage of base stations in a communication system, the system comprising a plurality of base stations and a plurality of user equipment each associated with at least one of the plurality of base stations, providing (S10) interference and noise information for each of at least a subset of the plurality of user equipment. Subsequently, identifying (S20) at least one interfering base station for at least one user equipment of the subset, and jointly analyzing (S30) the provided interference and noise information for the subset together with the identified at least one interfering base station. Finally, jointly adapting (S40) a transmitting power level and/or an antenna beam of the at least one identified interfering base stations based on the analysis, to provide reduced power consumption and increased coverage in the communication system.
