Abstract
This disclosure provides techniques for recovery techniques to address link failure in multi-hop backhaul relay network. For example, a central unit (CU) node receives, uplink transmissions originating from a user equipment (UE) via a backhaul relay including a first distributed unit (DU) node and a second DU node. The CU then receives a first UL status message associated with a link failure between the first DU node the second DU node. Then the CU generates a second UL status message indicating a sequence number (SN) of a lost packet caused by the link failure or a SN of a last successfully received packet before the link failure, and transmits the second UL status message to the first DU node.
