Embodiments of a method in an access node of a wireless communication network pre-emptively reduces intercell interference, ICI, in neighboring cells. The access node is configured to transmit downlink traffic to a plurality of user equipments, UEs, in a coverage area of the access node. At least one unscheduled physical resource block, PRB, is detected. Downlink traffic across is diluted across the at least one unscheduled PRB.
