Abstract: A method of receiving a demodulation reference signal (DMRS) by a user equipment (UE) in a wireless communication system. The method includes receiving a physical downlink control channel (PDCCH) through control resource set (CORESET) #0, and receiving a physical downlink shared channel (PDSCH) scheduled based on the PDCCH and a DMRS for the PDSCH. When the PDCCH is addressed to a system information-radio network temporary identifier (SI-RNTI), a reference point for the DMRS may be subcarrier #0 of a lowest-numbered resource block (RB) among RBs included in the CORESET #0.

Abstract: Provided are a method whereby a terminal transmits an acknowledgement/not-acknowledgement (ACK/NACK) with a primary cell and a secondary cell aggregated, and a device for supporting the method. The method comprises: receiving data by a downlink subframe of a secondary cell; and transmitting an ACK/NACK for the data by an uplink subframe of a primary cell, wherein: the time interval between the downlink subframe and the uplink subframe is determined by a first hybrid automatic repeat request (HARQ) timing or a second HARQ timing; the first HARQ timing is an HARQ timing which is applied when the primary cell is used alone; and the second HARQ timing is an HARQ timing which is additional to the first HARQ timing.
