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: 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.

Abstract: The present invention relates to a method and an apparatus for allowing a vehicle-to-everything (V2X) reception terminal to perform a hybrid automatic repeat request (HARQ) in a wireless communication system. More specifically, the method comprises the steps of: receiving a V2X signal which is broadcasted from a V2X transmission terminal; and transmitting, to the V2X transmission terminal, an acknowledgement/negative-acknowledgement (ACK/NACK) for the broadcasted V2X signal, wherein the ACK/NACK is configured to identify a location area, which corresponds to a location of a V2X reception terminal, among a plurality of location areas divided for ACK/NACK transmission on the basis of a location of the V2X transmission terminal.
