Claim:
1. A method for controlling uplink resource allocation for a plurality of basestations in a mobile communications network, wherein the basestations form a second layer within the network, and wherein the network comprises another plurality of basestations forming a first layer, the method comprising: 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, wherein the loading information for a second layer basestation comprises radio resource use of the second layer basestation and a noise rise contribution caused by one or more user equipments attached to the second layer basestation towards noise at the first layer basestation associated with the second layer basestation; dynamically controlling uplink resource allocation for individual second layer basestations based on the exchanged loading information; and dynamically controlling uplink transmit power limits for individual second layer basestations based on the exchanged radio resource use information and the exchanged noise rise contribution information, wherein dynamically controlling an uplink transmit power limit for a second layer basestation comprises, at the second layer basestation:
