Abstract:
1. A method in a network node of enabling inter-cell interference coordination, the network node including at least two antennas for multi-antenna transmission and/or reception and being included in a wireless communication network, the method comprising: detecting, by the network node, a current amount of spatially multiplexed data streams received on at least one block of radio resources; comparing the detected amount of spatially multiplexed data streams to at least two thresholds; transmitting, to at least one receiving network node in the wireless communication network and based on the comparing, an indication of an amount of spatially multiplexed data streams for at least one block of radio resources, the indication being for enabling inter-cell interference coordination based on the indication and for indicating which resource blocks the interference affects, wherein the indication comprises at least the number of spatially multiplexed data streams to be scheduled by the network node on at least one block of radio resources, thereby indicating a level of spatial interference that the network node expects to cause.
