1. An apparatus comprising:
a memory; and
at least one processor in communication with the memory, wherein the at least one processor is configured to cause an Integrated Access and Backhaul (IAB) node to:
decode radio resource control (RRC) signaling from a central unit (CU) function of an IAB donor node, the RRC signaling specifying a first configuration of first time-domain resources for a parent backhaul link between a mobile termination (MT) function of the IAB node and a distributed unit (DU) function of a parent IAB node;
decode F1 Application Protocol (F1-AP) signaling from the CU function of the IAB donor node, the F1-AP signaling specifying a second configuration, separate from the first configuration, of second time-domain resources for a child backhaul link between a DU function of the IAB node and a MT function of a child IAB node, wherein the F1-AP signaling specifies a number of uplink symbols, a number of downlink symbols, and a format indicating one of: downlink-flexible-uplink or uplink-flexible-downlink, for the second configuration;
encode uplink data for transmission to the parent IAB node based on the first time-domain resources specified by the first configuration; and
encode downlink data for transmission to the child IAB node based on the second time-domain resources specified by the second configuration.
