1. A wireless communication device comprising a memory and one or more processors configured to, when executing instructions stored in the memory, cause the wireless communication device to:
allocate distributed unit (DU) resources to a child IAB node, wherein the child IAB node is associated with a parent IAB node; and
in response to allocating DU resources to the child IAB node, transmit DU resource configuration information indicating one or more aspects of the DU resources to a DU function of the parent IAB node using F1-Application Protocol (AP) signaling that indicates, for each cell of the child IAB node, a resource configuration including frequency resource information.
