One embodiment of the present specification provides a method by which a machine type communication (MTC) device configured to operate only in some bands among the system bands of a cell transmits a demodulation reference signal (DMRS) for the demodulation of uplink data. The method can comprise the steps of: selecting any one DMRS sequence among a plurality of sets of DMRS sequences having a length M according to a group hopping number and allocation area information of a sub-physical resource block (PRB), when an uplink signal is transmitted through the sub-PRB including the M number of subcarriers which is less than twelve subcarriers; and mapping the selected DMRS sequence on the M number of subcarriers of the sub-PRB, and transmitting the same.
A method for transmitting a demodulation reference signal (DMRS) for demodulating uplink data, the method performed by a Machine Type communication (MTC) device configured to operate only in a part of bands of a system band of a cell and the method comprising:
