Abstract:
The present invention relates to a method for receiving a downlink signal by a terminal from a base station in a wireless communication system. In particular, the method includes the steps of: receiving an enhanced physical downlink control channel (EPDCCH) for the terminal from the base station; selecting a first EPDCCH physical resource block (PRB) pair or a second EPDCCH PRB pair on the basis of the effective size of a resource block group (RBG) allocated to the terminal and/or the system bandwidth; and receiving a physical downlink shared channel (PDSCH) on the basis of the EPDCCH form among the remaining PRB pairs excluding the selected EPDCCH PRB from among PRB pairs included in the RBG.
