Method and arrangement for load management in heterogeneous networks with interference suppression capable receivers

An arrangement for load management in a radio network control node associated with a plurality of radio base station nodes in a heterogeneous wireless communication system, the arrangement comprising:

• a receiving circuit configured to receive a first load measure and a second load measure and an estimated reference received total wideband power from at least one radio base station node in said system;
• a reconstructing circuit configured to reconstruct a neighbor cell interference level for said at least one radio base station node based on said first and second load measures and on said estimated reference received total wideband power;
• and
• a load management circuit configured to perform load management for said at least one radio base station node based on both said reconstructed neighbor cell interference level and said at least first and second load measure.
