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: Methods, systems, and devices for configuring user plane functions in mobile communication technology are described. An exemplary method for wireless communication includes determining, at a network node, a processing order for processing a plurality of user plane functions based on at least one of a type of service, a deployment type, a connection mode, one or more capabilities of the network node, or one or more capabilities of a wireless device, and transmitting, to the wireless device, a first control plane message comprising the processing order. Another exemplary method for wireless communication includes receiving, from a network node, a first control plane message comprising information that includes a processing order for processing a plurality of user plane functions, and processing, at the wireless device, a plurality of user plane functions based on the processing order.
