Method and a First Network Node for Controlling Load

A first network node configured to control load in a first cell of the first network node, wherein the first network node is comprised in a radio communication network, wherein the first network node comprises a multi-stage receiver for cancelling interference in multiple stages, wherein a first and a second radio communication device are associated with the first cell, wherein a third radio communication device is associated with a second cell of the radio communication network, wherein the first network node comprises:

• a processing circuit configured to compute an interference cancellation gain, at an intermediate stage of the multi-stage receiver, during an interference cancellation process for reducing interference between uplinks signals transmitted by the first and second radio communication devices, wherein the processing circuit further is configured to:
• estimate neighbour cell interference from interfering signals transmitted by the third radio communication device while accounting for a load utilization, wherein the load utilization relates to power transmitted by the first and second radio communication devices and power granted to the first and second radio communication devices;
• calculate a load measure for stability based on at least the interference cancellation gain and the neighbour cell interference;
• and
• control load in the first cell based on the load measure for stability.
