1. A method of operating a relay user equipment (UE) in a wireless communication system, the method comprising:
measuring, by the relay UE, a link quality between the relay UE and a source UE; and
receiving, by the relay UE, information related to a link quality between the relay UE and a remote UE from the remote UE,
wherein based on that the relay UE does not know a Quality of Service (QoS) required for messages, the relay UE performs resource reselection based on a difference between the link quality between the relay UE and the source UE and the link quality between the relay UE and the remote UE being greater than a predetermined value.
