Abstract
The present disclosure describes methods, systems, and devices for enhancing mobility robustness to integrated access and backhaul (IAB) for new radio (NR). One method includes enhancing mobility robustness of a migrating integrated access and backhaul-node (IAB-node) for NR during migration from a source IAB-donor-central unit (CU) to a target IAB-donor-CU by sending, by the source IAB-donor-CU, a handover request message to the target IAB-donor-CU, the handover request message comprising a dual active protocol stack (DAPS) request information. Another method includes enhancing mobility robustness of a migrating IAB-node for NR during migration from a source parent IAB-node to a target parent IAB-node by sending, by an IAB-donor-CU, a F1AP message to the migrating IAB-node, the F1AP message comprising a radio resource control re-configuration (RRCReconfiguration) message comprising a DAPS configuration information.
