Abstract: A method for receiving a signal by a user equipment (UE) in a wireless communication system is discussed. The method includes receiving, from a base station (BS), control information; and receiving, from the BS, downlink data on an unlicensed band cell (UCell) based on the control information. Further, in case of: the control information received on another serving cell, the downlink data is received in a first time resource, and the control information received on the UCell, the downlink data is received in a second time resource, and the second time resource is smaller than the first time resource.
