Abstract: Systems, apparatus, and methods of wireless communication are described, and more specifically, to techniques related to traffic transmission schemes for inter-donor redundancy and radio link failure (RLF) scenarios. One example method includes transmitting, from a first network node configured to communicate with a first integrated access and backhaul (IAB) node, to a second network node, a first message including information relating to dual connectivity (DC). The first and second network nodes can each be IAB-donors comprising an IAB-donor central unit (CU) and one or more IAB-donor distributed units (DU).

Abstract: The present disclosure describes methods, systems, and devices for informing at least one downstream device of a migrating integrated access backhaul node (IAB-node) about an inter-donor migration status of migrating IAB node undergoing a migration from a source IAB-donor to a target IAB-donor. The method includes receiving, by a receiving device, a radio resource control (RRC) message sent from an IAB-donor. The RRC message includes an information element which indicates an inter-donor migration status of a migrating IAB-node. The method further includes in response to the information element indicating a successful inter-donor migration, sending, by the receiving device, a packet data convergence protocol (PDCP) status reports to a target IAB-donor. The PDCP status report corresponds to a radio link control acknowledged mode (RLC-AM) bearer configured to be allowed to send the PDCP status report in an uplink, and is configured to update data transmission for the receiving device.

Abstract: The present disclosure describes methods, systems, and devices for recovering a recovery integrated access backhaul-node (IAB-node) for new radio (NR) from an initial IAB-donor-central unit (CU) to a new IAB-donor-CU and/or configuring a F1 connection between an IAB-node and an IAB-donor-CU. One method includes retrieving, by the new IAB-donor-CU from the initial IAB-donor-CU, context information; and configuring a connection with the recovery IAB-node. Another method includes sending, by the new IAB-donor-CU to the initial IAB-donor-CU, a request for retrieving user equipment (UE) context; and receiving, by the new IAB-donor-CU from the initial IAB-donor-CU, a response for retrieving UE context. Another method includes receiving, by the new IAB-donor-CU from the recovery IAB-DU, a first message to initiate a first F1 procedure; sending, by the new IAB-donor-CU to the recovery IAB-DU, a second message to indicate whether the first F1 procedure is successful.
