Abstract: A source Integrated Access Backhaul, IAB, node (20) sends a handover request (110) from the source IAB node (20) to a target IAB node (30) to which a Mobile Termination, MT, (10) of an IAB node is to be migrated.

Abstract: Systems, methods, and apparatus are disclosed for a user equipment. An example method performed by a user equipment includes establishing a connection to a Radio Access Network (RAN) via a first network node. Communications are provided over the connection using Signaling Radio Bearer 1 (SRB1) configured with a New Radio (NR) Packet Data Convergence Protocol (PDCP).

The connection re-establishment message includes a radioResourceConfigDedicated information element (IE). The user equipment re-establishes the connection to the RAN by applying a Long-Term Evolution (LTE) PDCP configuration to SRB1, performing a radio resource configuration procedure in accordance with the radioResourceConfigDedicated IE, and sending an RRC connection re-establishment complete message to the second network node.
