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.

Abstract: According to one embodiment of the present invention, a method of receiving a downlink signal, which is received by a user equipment in a wireless communication system, includes the steps of receiving a TxPowerResourceConfigList for a user equipment which is not configured with a transmission mode 10 and one or more zeroTxPowerResourceConfigLists and receiving a DCI (downlink control channel) including a PRI (PDSCH RE mapping indicator). In this case, the user equipment can recognize whether a PDSCH (physical downlink shared channel) is mapped to REs (resource elements) to which a CSI-RS is transmittable using the one or more zeroTxPowerResourceConfigLists and the PRI.
