Abstract: The present specification provides a method for transmitting an MPDCCH in a wireless communication system supporting MTC. More specifically, the method performed by a base station comprises the steps of: mapping an MPDCCH to resource elements (REs); and transmitting the MPDCCH on the REs to a terminal, wherein the mapping of the MPDCCH comprises a step of copying REs used for the MPDCCH in at least one symbol of a second slot of a subframe onto at least one symbol of a first slot of the subframe.

Abstract: According to one embodiment, a distance technique between a transmitter and a receiver for processing a signal in symbol units is presented. According to the embodiment, the transmitter transmits a transmission signal to the receiver through preset first and second frequencies. Then, the transmitter receives, from the receiver, a reception signal corresponding to the transmission signal. The reception signal includes a first reception component corresponding to the first frequency and a second reception component corresponding to the second frequency. The phase difference set by the receiver is applied between the phase of the first reception component and the phase of the second reception component. The phase difference is set on the basis of the difference between a reception time at which the transmission signal is received by the receiver and a processing time at which the transmission signal is processed in the receiver.
