As further shown in FIG. 6, a link between an IAB donor 605 and an IAB node 610 or between two IAB nodes 610 may be referred to as a backhaul link 620. Backhaul link 620 may be a wireless backhaul link that provides an IAB node 610 with radio access to a core network via an IAB donor 605, and optionally via one or more other IAB nodes 610. In an IAB network, network resources for wireless communications (e.g., time resources, frequency resources, spatial resources, and/or the like) may be shared between access links 615 and backhaul links 620. In some aspects, a backhaul link 620 may be a primary backhaul link or a secondary backhaul link (e.g., a backup backhaul link). In some aspects, a secondary backhaul link 625 may be used if a primary backhaul link 620 fails, becomes congested, becomes overloaded, and/or the like. For example, a secondary backhaul link 625 between IAB-node 2 and IAB-node 3 may be used for backhaul communications if the primary backhaul link between IAB-node 2 and IAB-node 1 fails. As used herein, “node” or “wireless node” may refer to an IAB donor 605 or an IAB node 610.
As indicated above, FIG. 6 is provided as an example. Other examples may differ from what is described with regard to FIG. 6.
FIG. 7 is a diagram illustrating examples 700 relating to inter-DU CLI, in accordance with the present disclosure.
