Abstract: A method for receiving Physical Downlink Shared Channel (PDSCH) in a user equipment (UE) from a base station (BS) in a wireless communication system. In the method, the UE receives information for at least one control resource set (CORESET) and information for a CORESET not used for the PDSCH among the CORESET. Furthermore, the UE receives the PDSCH in resources other than the CORESET not used for the PDSCH. In other words, the PDSCH is not mapped into the CORESET not used for the PDSCH. In addition, a demodulation reference signal (DMRS) for the PDSCH is received in an orthogonal frequency division multiplexing (OFDM) symbol after the at least one CORESET when a region for PDSCH overlaps a region for the at least one CORESET.

Abstract: The disclosure of the present specification provides a method for receiving a downlink control channel in a machine type communication (MTC) device configured to operate in only a partial band of the system band of a cell. The method may comprise the steps of: considering the number of physical resource block (PRB) pairs, to which a downlink control channel can be mapped, to be one of 2, 4, and 8; when the considered number of PRB pairs is greater than the number of PRB pairs to which the downlink control channel is actually mapped, determining that the downlink control channel is not included in PRB pairs except the number of PRB pairs to which the downlink control channel is actually mapped; and receiving the downlink control channel in only as many PRB pairs as the number of PRB pairs to which the downlink control channel is actually mapped, on the basis of the determination.
