Abstract: The present invention relates to a method for a terminal receiving an enhanced physical downlink control channel (EPDCCH) in a wireless access system supporting an unlicensed band, and the method may comprise the steps of: receiving, through an unlicensed-band cell (Ucell) configured in an unlicensed band, an EPDCCH comprising control information for scheduling the Ucell; and, on the basis of the control information, receiving downlink data from the Ucell. Here, if the EPDCCH is transmitted through a partial subframe (pSF), enhanced resource element groups (EREGs) constituting the EPDCCH are indexed from the start symbol of the pSF, and the pSF has a smaller size than one subframe, and the starting position of the pSF may not correspond to the subframe boundary of a primary cell (Pcell) configured in a licensed band.
