Abstract
A method and apparatus for lossless uplink data transmission of IAB network in a wireless communication system will be provided. A user plane (UP) of an integrated access and backhaul (IAB)-donor central unit (CU) in a wireless communication system receives, from a wireless device, uplink data through a source IAB-node. A UP of an IAB-donor CU receives, from the source IAB-node, at least one of a delivery status of the uplink data on the source IAB-node, wherein the wireless device handovers from the source IAB-node to a target IAB-node. A UP of an IAB-donor CU transmits, to a unit-control plane (CP) of the IAB-donor CU, a first message based on the at least one of the delivery status of the uplink data.
