Abstract: A method and apparatus for delaying transmission or reception on an unlicensed cell in a wireless communication system is provided. A user equipment (UE) receives a backoff time from a first cell, and delays downlink (DL) reception or uplink (UL) transmission on a second cell during the backoff time. Alternatively, a method and apparatus for determining whether to perform transmission or reception on an unlicensed cell in a wireless communication system is provided. A UE receives an access probability factor from a first cell, and determines whether or not to perform DL reception or UL transmission on a second cell based on the access probability factor. The first cell is a first serving cell on a licensed carrier, and the second cell is a second serving cell on an unlicensed carrier.
