Abstract: A method for receiving downlink data by the terminal in a wireless communication system, includes receiving, from a base station, downlink control information for scheduling a short physical downlink shared channel (sPDSCH) on a short physical downlink control channel (sPDCCH), and receiving, from the base station, downlink data on the sPDSCH based on the downlink control information. Here, the sPDCCH and the sPDSCH are based on a first transmission time interval (TTI)-based radio frame structure, wherein the first TTI-based radio frame structure is shorter in time than a second TTI-based radio frame structure related to (i) a physical downlink shared channel (PDSCH) and (ii) a physical downlink control channel (PDCCH). Further, a number of resource element groups (REGs) consisting of a control channel element (CCE) related to the sPDCCH is smaller than a number of resource element groups (REGs) composed of a CCE related to the PDCCH.
