Abstract: A method for managing a radio link in an unlicensed band is provided. An apparatus attempts to receive a discovery reference signal (DRS) in a serving cell that is operated in the unlicensed band. The apparatus determines that a radio link to the serving cell has failed if the DRS is not received for a predetermined time.
