Abstract: The present specification provides a reception method of a machine type communication (MTC) device. The reception method can comprise the steps of: receiving a control channel through the entire system bandwidth on first and second orthogonal frequency division multiplexing (OFDM) symbols of a subframe; and determining whether to receive a data channel only in a reduced bandwidth compared with the system bandwidth from the third symbol of the subframe. At this point, when the control channel does not continue up until a third symbol of the subframe, the data channel can be received in a reduced bandwidth compared with the system bandwidth from the third symbol of the subframe.

Abstract: The present invention relates to a method for receiving a downlink control signal in a TDD-based wireless communication system, and to an apparatus therefor. The method comprises receiving a downlink signal via a downlink interval in a specific frame including the downlink interval, a guard interval and an uplink interval. A combination of the downlink interval, the guard interval and the uplink interval is given using configuration information on the specific subframe. When the configuration information is given such that the length of the downlink interval is larger than a specific value, detecting a first type of PDCCH is performed in the specific subframe. When the configuration information is given such that the length of the downlink interval is equal to or smaller than the specific value, detecting the first type of PDCCH is skipped in the specific subframe.
