    摘要： The present invention relates to a method of a network node for improving utilization of resources of a cell 102 provided by a radio base station (RBS), the cell covering a geographical area and being a cell served by a low power node (LPN) 101 of the RBS in a heterogeneous network 100. The method comprises determining a load of downlink (DL) resources of the cell used for wireless communication terminal(s) 104 connected to the cell. The method also comprises deciding, based on said determined load, that the DL bandwidth of the cell available for scheduling should be adjusted, allowing the power of the LPN to be reallocated for the adjusted bandwidth available for scheduling whereby a transition zone area 103 between the LPN and at least one neighboring node 105 will be adjusted accordingly. The transition zone is an area in which a path-loss is lower to the LPN than to the at least one neighboring node but a received DL power density is lower from the LPN than from the at least one neighboring node.
