Abstract: The present specification discloses an invention relating to a method for transmitting an MTC physical downlink control channel (MPDCCH) by a base station in a wireless communication system supporting machine type communication (MTC). According to the present invention, a base station transmits, to a terminal, configuration information related to the transmission of an MPDCCH and maps the MPDCCH onto multiple resource elements (REs) of at least one first symbol constituting a first slot of a special subframe. The special subframe is a subframe in which, among symbols constituting the subframe, the number of symbols for data transmission is smaller than or equal to a predetermined number. The base station transmits the MPDCCH to the terminal over the multiple resource elements, wherein the mapping step is performed by copying at least one second symbol of a second slot adjacent to the first slot onto the at least one first symbol.
