Claim:
1. A method, in a network node in a wireless communication network, for controlling uplink power control within an area comprising at least one macro Radio Base Station (RBS) and at least one low power RBS, the method comprising: collecting measurement reports from one or more user equipment (UE) located within the area; creating clusters of low power RBSs and macro RBSs based on the collected measurement reports, wherein each cluster comprises one low power RBS and at least one macro RBS; for each low power RBS in a cluster, identifying both a macro RBS with a lowest pathloss based on the collected measurement reports for those UE connected to the low power RBS and the level of the pathloss; determining, based on the collected measurement reports for those UE connected to the identified macro RBS, an interference level in the low power RBS caused by UE connected to the identified macro RBS; selecting an uplink power control setting for the low power RBS based on the size of the pathloss associated with the identified macro RBS and the interference level in the low power RBS caused by UE connected to the identified macro RBS; and instructing UE connected to the low power RBS to use the selected uplink power control setting.
