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 Vehicle-to-X (V2X) communication method performed by a terminal in a wireless communication system. The method comprises: determining priority of information related to the V2X communication; selecting a transmission time interval (TTI) on the basis of the priority; and transmitting the information on the basis of the selected TTI. If the information related to the V2X communication is information having high priority, a first TTI is selected, and if the information related to the V2X communication is information having relatively lower priority than the information having high priority, a second TTI is selected.

Abstract: The present invention relates to a method and an apparatus for transmitting information among base stations for inter-cell interference cancellation in a massive MIMO or FD-MIMO system. A base station acquires interference area information, which is information on an area causing interference to a neighbor base station, and transmits the interference area information to the neighbor base station. The interference area information may include any one from among the vertical and horizontal angles of a beam causing interference to the neighbor base station, or the number of the area causing interference to the neighbor base station.
