    摘要: A method and device are disclosed from the perspective of a User Equipment-to-User Equipment, UE-to-UE, Relay to perform a link identifier update procedure. In one embodiment, the method includes the UE-to-UE Relay receiving a first PC5-S message from a first UE to modify at least one first link identifier, wherein the first PC5-S message includes a Layer-2 Identity, ID, of the first UE (1405). The method also includes the UE-to-UE Relay transmitting a second PC5-S message to a second UE, in response to reception of the first PC5-S message, to modify at least one second link identifier, wherein the second PC5-S message includes a Layer-2 ID of the UE-to-UE Relay and does not include the Layer-2 ID of the first UE (1410).
