A node of an Integrated Access and Backhaul (IAB) network comprises processor circuitry and interface circuitry. The processor circuitry is configured to make a determination concerning crosslink interference (CLI) between (a) a beam transmitted from a parent node to the IAB node and (b) a beam transmitted from the IBA node to a child node of the IAB node; and in accordance with the determination, and to generate a command configured to modify a property of the beam transmitted from the parent node to the IAB node. The interface circuitry is configured to transmit the command to a beam controller of the parent node.
