Abstract: Disclosed are a method for generating a random access signal of a machine type communication (MTC) device using a narrow bandwidth, and an MTC device. The method generates a random access signal by allocating a position in a frequency domain of a random access signal dedicated to the MTC device, that is, a position of a frequency for transmission of a random access preamble, to a center position of a base station system bandwidth, or by shifting a center frequency of the MTC device to a position of a random access frequency allocated for a legacy LTE terminal by a base station.
