Dual connectivity mobility management with L2 ue-to-network relay

An apparatus for wireless communication at a remote user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• transmit, to at least one of a source master network entity or a target master network entity, an indication of a first entity change from the source master network entity to the target master network entity and a second entity change from a source secondary network entity to a target secondary network entity, the remote UE being connected to the source master network entity through a first relayed link via a first relay UE before the first entity change;
• receive, from the target master network entity, a measurement configuration during a radio resource control (RRC) reestablishment procedure with the target master network entity;
• transmit, to the target master network entity during the RRC reestablishment procedure, one or more measurements corresponding to the second entity change;
• receive, from the target master network entity, a dual connectivity configuration based on the transmitted one or more measurements, the dual connectivity configuration corresponding to the first entity change and the second entity change, the remote UE being connected to the target master network entity through a second relayed link via a second relay UE after the first entity change;
• and
• communicate with the target master network entity and the target secondary network entity based on the dual connectivity configuration.
