Abstract
It is presented a method for reducing interference between network nodes of a cellular network, the method being performed in an aggressor network node, being a network node risking to interfere with transmissions to a first wireless device by a victim network node. The method comprises the steps of: receiving a transmission avoidance request from the victim network node, the transmission avoidance request comprising a reference to at least one risk resource unit intended to be used for transmissions by the victim network node to the first wireless device; determining whether to avoid user data transmissions to a second wireless device using the at least one risk resource unit; and when it is determined to avoid user data transmissions using the at least one risk resource unit, avoiding user data transmission using the at least one risk resource unit.
