摘要
The present invention concerns a method and system for reducing co-channel interference due to the deployment of N femtocells in a macrocellular network. Said method comprises a step (1) of taking power measurements on signals sent over this network, a step (3) of optimising the transmission powers of the femtocells according to these measurements, and a step (4) of allocating to each femtocell its transmission power. Said method is characterised in that: during step (1) of taking measurements, the power measurements are only made by the N femtocells and these measurements are ordered temporally by a central facility UC in the system, during the optimisation step (3), the transmission powers of the femtocells are maximised under the constraint of maintaining a minimum quality of service of terminals that would be attached to the base stations in the macrocellular network.
