Abstract: The present invention relates to a method for receiving a downlink control signal in a wireless communication system including monitoring EPDCCH (enhanced physical downlink control channel) candidates to decode an EPDCCH in one or two EPDCCH sets on a first serving cell configured for the UE, and receiving a PDSCH (physical downlink shared channel) corresponding to the decoded EPDCCH. The EPDCCH candidates may include EPDCCH candidates for the first serving cell and EPDCCH candidates for a second serving cell scheduled by the first serving cell. Aggregation levels and the number of the EPDCCH candidates for the second serving cell at each of the aggregation levels are associated with bandwidth of the second serving cell.

Abstract: The present invention relates to a method of transmitting CSI-RS (channel state information-reference signal) configuration, which is transmitted by a base station in a wireless communication system, and an apparatus therefor. Specifically, the method includes the steps of composing an information element configuring a first CSI (channel state information) subframe set and a second CSI subframe set and transmitting the CSI-RS configuration including at least one or more ZP-CSI-RS configurations (zero power CSI-RS configuration). The CSI-RS configuration includes a first ZP-CSI-RS configuration for a first user equipment to which the information element is not set and a second user equipment to which the information element is set and a second ZP-CSI-RS configuration for the second user equipment only.
