Abstract:
A method and apparatus are disclosed for using alternate paths for descendant nodes for backhaul failure link reporting. In one embodiment, a method for a network node that may be a parent node includes receiving information indicating at least one alternate path of at least one child IAB node to an IAB donor node, the at least one child IAB node being a wireless backhaul node; and using the received information to perform at least one of a backhaul wireless link failure recovery and load balancing of traffic. In another embodiment, a method for a network node that may be a child node includes receiving information indicating at least one alternate path of a parent IAB node to an IAB donor node, the parent IAB node being a wireless backhaul node for the child IAB node. The received information is used to perform at least one operational task.
