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.

Abstract: A method for a user equipment (UE) performing measurements is provided. The UE performs measurements for a first cell and measurements for a second cell. If the first cell corresponds to a primary cell, a first measurement subframe pattern is applied to perform the measurement for the first cell. If the second cell does not correspond to the primary cell and if the second cell is in a deactivated state, a measurement timing configuration for a discovery signal is applied to perform the measurement for the second cell.

Abstract: In this application, a method for a terminal reporting to a base station a channel quality indicator (CQI) in a wireless communication system is disclosed. More specifically, the method comprises the steps of: calculating a precoding matrix index and a rank indicator; and selecting and reporting the CQI index from one of a first CQI index table and a second CQI index table under the assumption that the precoding matrix index and the rank indicator are applied, wherein the first CQI index table and the second CQI index table indicate a modulation order and a coding rate indicated by the CQI index, and the second CQI index table supports a higher modulation order than the first CQI index table.
