Embodiments of the present disclosure provide a Radio-resource management (RRM) configuration device, and corresponding method, for a network comprising a plurality of access nodes. The device is configured to divide the plurality of access nodes of the network into clusters, and to select at least one access node of each cluster as RRM controller. Further, the device is configured to determine the non-selected access nodes of each cluster as slave nodes, and to select, for each cluster, an RRM split between each slave node and the at least one RRM controller of the respective cluster. The device is also configured to transmit, to each access node, information about its cluster, the at least one RRM controller of the cluster, and the selected RRM split.
