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 provides a method for carrying out S-TTI-based communication performed by a terminal supporting a relatively short transmission time interval (S-TTI) compared to a legacy transmission time interval (L-TTI) in a wireless communication system. The method is characterized by: determining a value with respect to a ratio of reference signal energy per resource element (RS EPRE) to physical downlink shared channel energy per resource element (PDSCH EPRE); and carrying out S-TTI-based communication on the basis of the value with respect to the ratio, wherein the value with respect to the ratio is determined in an S-TTI unit.
