The present invention relates to a method for enabling intercell interference coordination in a network node 112, 132, which is comprised in a wireless communications network 100. The network node 112, 132 comprises at least two antennas for multi-antenna transmission and/or reception. According to the method, the network node 112, 132 transmits an indication of an amount of spatially multiplexed streams for at least one block of radio resources to at least one receiving network node 122, which is also comprised in the wireless communications network 100. By indicating the amount of spatially multiplexed streams, it is made possible for the receiving network node 122 to take the intercell interference in the spatial domain into consideration, for instance in a scheduling and/or link adaptation decision.
