Summary:A method and device are disclosed from the perspective of a relay UE for Radio Resource Control, RRC, connection establishment to support User Equipment, LTE, -to-Network relaying. In one embodiment, the method includes a relay UE establishing a PC5 RRC connection or a PC5 unicast link with a remote UE (1705). The method also includes the relay UE receiving a RRC message from the remote UE (1710). Furthermore, the method includes the relay UE initiating a RRC connection establishment with a network node in response to reception of the RRC message (1715). In addition, the method includes the relay UE transmitting a Disconnect Request message to the remote UE to release the PC5 RRC connection or the PC5 unicast link or transmits a PC5 RRC message to the remote UE to inform the remote UE of a failure of the RRC connection establishment, if the RRC connection establishment fails (1720).
