摘要：
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.
