摘要：
A method and device are disclosed from the perspective of a relay UE. In one embodiment, the relay UE establishes a Radio Resource Control (RRC) connection with a network node. The relay UE also transmits a Layer 2. Identity (L2ID) of the relay UE to the network node. Furthermore, the relay UE receives a local UE Identity (ID) for a remote UE and a L2ID of the remote UE from the network node. In addition, the relay UE establishes a PC5 connection with the remote UE. The relay UE further receives a first RRC Reconfiguration Complete message from the remote UE. The relay UE also transmits the first RRC Reconfiguration Complete message to the network node, wherein the first RRC Reconfiguration Complete message is included in an adaptation layer Protocol Data Unit (PDU) for transmission and the local UE ID for the remote UE is included in a header of the adaptation layer PDU.
