Abstract: Disclosed herein is a method for receiving a demodulation reference signal (DMRS) in a wireless communication system. In particular, the method may include receiving a synchronization signal/physical broadcast channel (SS/PBCH) block, acquiring information about control resource set (CORESET) #0 from a PBCH included in the SS/PBCH block, receiving a physical downlink control channel (PDCCH) through CORESET #0, and receiving a physical downlink shared channel (PDSCH) scheduled based on the PDCCH and a DMRS for the PDSCH, wherein, based on the PDCCH being addressed to a system information-radio network temporary identifier (SI-RNTI), a reference point for the DMRS may be subcarrier #0 of a resource block (RB) having a lowest number among RBs included in CORESET #0.

Abstract: The present invention relates to a method for signal transmission or reception by a terminal dual-connected to a first radio access technology (RAT) or a second RAT in a wireless communication system. Specifically, the method comprises: a step of receiving a first RAT-based downlink reference time domain duplex (TDD) uplink-downlink configuration; and a time division multiplexing (TDM) step of, when an uplink subframe on the basis of the downlink reference TDD uplink-downlink configuration is associated with a first transmission time unit having a predetermined length, setting the first transmission time unit for the first RAT and setting a second transmission time unit for the second RAT. The second transmission time unit is obtained by excluding a transmission time unit from the uplink subframe. The terminal is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: Disclosed is a method for a terminal reporting channel status information (CSI) to a base station in a wireless communication system. The method comprises receiving, via an upper later, information associated with a single CSI process comprising a firs enhanced multiple input multiple output (eMIMO) type and a second eMIMO type; reporting, to a base station, a first CSI updated on the basis of a first channel status information-reference signal (CSI-RS) corresponding to the first eMIMO type received from a first subframe; and receiving, from the base station, a triggering message of a second CSI calculated on the basis of a second CSI-RS corresponding to the second eMIMO type from a second subframe.

Abstract: The present invention relates to a method for an NR (New Radio Access Technology) user equipment to transmit and receive a signal in a wireless communication system and an apparatus therefor. The method comprises the steps of checking a PDCCH (Physical Downlink Control Channel) order and, if the PDCCH order is checked, initiating a random access procedure. In this case, if a first uplink carrier and a second uplink carrier are configured, the random access procedure is configured to transmit a random access preamble via a specific uplink carrier corresponding to an indicator associated with the PDCCH order among the first uplink carrier and the second uplink carrier.
