In a method of uplink interference congestion control in an interference suppression capable receiving node associated with a plurality of users in a wireless communication system, applying interference suppression to received signals in the node, to provide interference suppressed received signals. Subsequently, estimating a rise over thermal value for the uplink, based on the interference suppressed received signals, and determining a load measure for the uplink based on the estimated rise over thermal value. Finally, controlling interference congestion on the uplink based on the determined load measure.
