摘要： A network controller as well as a method in a network controller for coordinating resource assignments to radio access points of a superdense, SDN, network is provided. The method comprises identifying a set of radio access points in the SDN network whose respective radio resource assignment is to be independently coordinated. The method also comprises obtaining interference information indicative of the extent to which radio transmissions to or from different radio access points in the set would interfere with one another absent radio resource assignment coordination. The method then forms subsets of the radio access points in the set based on this obtained interference information. The method also assigns different subsets of radio resources to the different subsets of the radio access points, and reports assignment information to the radio access points in the set, indicating the assignment of radio resources.
