Abstract: According to one embodiment of the present invention, a method of receiving DCI by a UE includes receiving bundling information regarding REGs via higher layer signaling, performing blind detection for a PDCCH in a CORESET configured on a plurality of OFDM symbols, and acquiring DCI from the PDCCH. When the bundling information indicates a first value, the UE may perform bundling such that only REGs locating on a same RB and corresponding to different OFDM symbols in the CORESET, are bundled as 1 REG bundle, and when the bundling information indicates a second value, the UE may perform bundling such that the REGs locating on the same RB and corresponding to the different OFDM symbols are bundled as 1 REG bundle along with REGs locating on different RBs in the CORESET, and the UE may perform the blind detection of the PDCCH by assuming same precoding for REGs belonging to a same REG bundle as a result of REG bundling.

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.
