A method for processing signals at a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of receiving a relay configuration message from a network via a dedicated signaling, the relay configuration message including at least one condition for which the UE considers itself as a valid relay; performing relay functions when the at least one condition is met; and transmitting a notification message for notifying an expiration of functioning as the valid relay to the network when the at least one condition is not met.
