A disclosure of the present specification provides a transmission and reception method of a machine type communication (MTC) device. The transmission and reception method of the MTC device may comprise the steps of: receiving first scheduling information indicating that a bundle of first data can be transmitted or received in multiple first sub-frames; and receiving second scheduling information indicating that a bundle of second data can be transmitted or received in multiple second sub-frames. Herein, when a physical resource block (PRB) of some sub-frames of the multiple first sub-frames overlaps a PRB of some sub-frames of the multiple second sub-frames, only one of the bundle of the first data and the bundle of the second data can be transmitted and received in the overlapping sub-frame.
