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: Provided in the present specification is a method for transmitting uplink control information (UCI) in a wireless communication system. More particularly, a method performed by a terminal comprises the steps of: receiving, from a base station, first downlink control information (DCI), wherein the first DCI includes configuration information related to resources for transmitting first UCI and the configuration information indicates, to the terminal, a pre-empted resource by another terminal from among preset resources; determining a reference resource region, which is a range for recognizing the pre-empted resource; and transmitting, to the base station, the first UCI on a residual resource excluding the pre-empted resource from the determined reference resource region.
