Abstract: The present invention relates to a method and an apparatus for a base station transmitting a downlink signal for a machine-type communication (MTC) terminal. More specifically, the present invention relates to a method for transmitting and receiving PBCH, PRACH, PDSCH, PDCCH or EPDCCH for a low cost and enhanced coverage MTC terminal, and an apparatus therefor. Particularly, provided are an apparatus and a method for a base station transmitting a control channel, the method comprising the steps of repeatedly transmitting a control channel comprising control information, and repeatedly transmitting downlink data channel (PDSCH) on the basis of information for a subframe ending the control channel being repeatedly transmitted.
