It is presented a method for assisting handling of interference at a receiver device. The method is performed in a network node and comprises the steps of: determining a parameter indicating a maximum number of interfering streams for which interference suppression is likely to be successful at the receiver device; determining that a number of potentially interfering streams at the receiver device exceeds the maximum number of interfering streams indicated by the parameter; and scheduling transmissions to avoid that the number of concurrent interfering streams at the receiver device exceeds the maximum number of interfering streams indicated by the parameter. A corresponding network node is also presented.
