FIG. 11 shows yet another example diagram of a telecommunications system 20 comprising wireless access node 22-1, also known as Donor node 1; wireless access node 22-2, also known as Donor node 2; IAB-node 24A, also known as Node A or relay node A; IAB-node 24B, also known as Node B or relay node B; and child node 1, also known as child node 30. The child node 30 may be, for example, a user equipment, UE, or an Integrated Access and Backhaul (IAB) node, as previously described. The wireless access node 22-1 and wireless access node 22-2 may be connected by a wired backhaul link 32. The other elements of FIG. 11 may be connected by wireless backhaul links, e.g., the wireless access node 22-1 may be connected by wireless backhaul link 34A to IAB-node 24A; the wireless access node 22-2 may be connected by wireless backhaul link 34B to IAB-node 24B; the IAB-node 24A may be connected by wireless backhaul link 36A to child node 30; and the IAB-node 24B may be connected by 36B to child node 30.
