Abstract
Network nodes and methods therein for inter cell interference coordination. A method in a base station BS1 comprises receiving, from a neighboring base station BS2, an indicator A, related to estimated spatial properties of a radio channel over which the neighboring base station has received a radio signal from the base station BS1. The method further comprises receiving, from a UE served by the base station, an indicator B related to estimated spatial properties of a radio channel over which the UE has received a radio signal from the base station BS1. The method further comprises determining a correlation based on indicator A and indicator B; and adapting a transmission to the UE, based on properties of the correlation. By performing the method, the base station BS1 enables control of interference subjected towards the neighboring base station BS2 caused by downlink transmission to the UE.
