Abstract: The present invention relates to a method for performing a random access procedure in a wireless communication system and a device therefor, the method comprising a step for receiving NPRACH configuration information and a step for transmitting a random access preamble on the basis of the NPRACH configuration information, wherein the NPRACH configuration information includes information indicating whether only a first preamble format is supported, only a second preamble format is supported, or both the first preamble format and the second preamble format are supported. If both the first preamble format and the second preamble format are supported according to the NPRACH configuration information, the random access preamble is transmitted using the first preamble format, and, if both the first preamble format and the second preamble format are supported according to the NPRACH configuration information, the random access preamble is transmitted using the second preamble format.

Abstract: Provided are a method and device for monitoring a PDCCH of a terminal in a wireless communication system. The terminal receives first setting information that provides notification of a monitoring occasion for detecting a wake up signal (WUS), and performs monitoring for detecting the wake up signal in the monitoring occasion. If the wake up signal is not detected in the monitoring occasion, whether to monitor a PDCCH in the next DRX-on period is determined on the basis of second setting information that indicates the operation to be applied to the terminal when the terminal does not detect the wake up signal.

Abstract: Provided are a method and device for transmitting and receiving a signal in a wireless communication system according to an embodiment of the present invention, the method comprising: receiving DCI for scheduling a PUSCH; and transmitting the PUSCH on the basis of the DCI. An FDRA field in the DCI includes LSBs of K bits including information about an RB set. The K bits are converted into L bits on the basis of the number N of RB sets set in the current active BWP being different from the number M of RB sets set in a specific BWP.

Abstract: A method and device for transmitting and receiving signals in a wireless communication system according to one embodiment of the present invention stay awake by means of a DRX operation and transmit a PUCCH including UCI. An interlace for transmitting the PUCCH is on the basis of (i) an index of a first interlace being set lower than an index of a second interlace, and (ii) the number of PRBs for transmitting the UCI being less than or equal to the number of PRBs of the first interlace, so that the PUCCH is determined as the first interlace among the first interlace and the second interlace.
