PROBLEM TO BE SOLVED: To provide a suitable method and device for receiving a downlink signal in a radio communication system.SOLUTION: One embodiment of the present invention is a downlink signal receiving method in a method by which a terminal in a radio communication system receives a downlink signal via an EPDCCH (Enhanced Physical Downlink Control Channel). The downlink signal receiving method includes the steps of: receiving a demodulation reference signal by EPDCCH PRB (Physical Resource Block) set; and trying the demodulation of the EPDCCH by the EPDCCH PRB set by referring to the demodulation reference signal. If a transmission mode set to the terminal is a preset transmission mode, the terminal presumes that a cell specific reference signal for a serving cell and the demodulation reference signal are QCL (Quasi Co-Located).SELECTED DRAWING: Figure 9 |
