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) performs downlink (DL) reception or uplink (UL) transmission on a second cell. The second cell is a second serving cell on an unlicensed carrier. The UE receives a backoff time for the second cell from a first cell when there is overload in the unlicensed carrier. The first cell is a first serving cell on a licensed carrier. The UE suspends ongoing DL reception or UL transmission on the second cell during the backoff time.
