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: Disclosed is a method for transmitting an uplink signal to a base station by a terminal in a wireless communication system. Specifically, the method comprises the steps of: detecting a downlink control signal from the base station through a terminal-specific search space or a common search space at a first time point; and transmitting an uplink signal corresponding to the downlink control signal to the base station on the basis of the downlink control signal, wherein, when the downlink control signal is detected in the terminal-specific search space, the uplink signal is transmitted at a second time point, and when the downlink control signal is detected in the common search space, the uplink signal is transmitted at a third time point.

Abstract: A method of receiving Downlink (DL) data by a User Equipment (UE) in a wireless communication system. The method includes: receiving information related to a number of repetitions of the DL data which is repeatedly transmitted in (i) at least one first Transmission Time Interval (TTI) included in a first subframe, and in (ii) at least one second TTI included in a second subframe that is after the first subframe; and receiving the DL data based on the number of repetitions of the DL data. If a Transmission Mode (TM) for the first subframe is different from a TM for the second subframe, then the UE does not receive the DL data in the at least one second TTI.
