Abstract: A method of receiving a Physical Downlink Shared Channel (PDSCH) includes: receiving, in a first bandwidth part (BWP), a downlink control information (DCI) including (i) first information that indicates switching an active BWP from the first BWP to a second BWP, and (ii) second information related to scheduling at least one transport block (TB) for the PDSCH; and receiving, in the second BWP, the PDSCH based on the first information and the second information. Based on a number of TBs in a first group of TBs that can be scheduled through the second information being equal to one, and based on a number of TBs in a second group of TBs that can be scheduled for the second BWP being equal to two: among the second information related to scheduling the at least one TB, information related to a second TB among the second group of TBs is disabled.

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: A method and an apparatus for power control in a wireless communication system are provided. When long-term evolution (LTE) and a new radio access technology (NR) are combined by means of dual connectivity (DC), etc., dynamic resource sharing can be used. Specifically, a user equipment (UE) determines whether or not uplink (UL) transmission is performed at a specific time point in a first carrier having a first processing time. When it is determined that UL transmission is not performed at the specific time point in the first carrier, the UE determines power for UL transmission at the specific time point in a second carrier having a second processing time shorter than the first processing time, on the basis of guaranteed power for the first carrier.
