Abstract
A method for controlling uplink transmit power for a plurality of basestations in a mobile communications network is disclosed. The basestations may form a second layer within the network, and the network may comprise another plurality of basestations forming a first layer. The method comprises clustering the plurality of second layer basestations according to association with first layer basestations, exchanging second layer basestation loading information between second layer basestations belonging to the same cluster, and dynamically setting uplink transmit power limits for individual second layer basestations based on the exchanged loading information. The method may further comprise updating the clustering of the second layer basestations according to dynamic variation in association of second layer basestations with first layer basestations. The method may also comprise dynamically controlling uplink resource allocation such that concurrent use of the same frequency resource by more than one second layer basestation is reduced.
