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 are a method for receiving a signal in a control resource set (CORESET) of a wireless communication system and a user equipment (UE) using the method. The method includes receiving a radio resource control (RRC) signal including a plurality of transmission configuration indicator (TCI) states, receiving a medium access control (MAC) control element (CE) informing one of the plurality of TCI states and receiving a signal in the CORESET based on the one TCI state. When the CORESET is CORESET #0, the one TCI state is related with a reference signal associated with a synchronization signal/physical broadcast channel block (SSB).
