    Abstract: One embodiment of the present invention relates to a method and a device for transmitting and receiving a signal in a wireless communication system, the method comprising the steps of: performing a random access procedure; monitoring a physical downlink control channel (PDCCH) for an ON duration on the basis of a configured discontinuous reception (DRX) operation after performing the random access procedure; and operating an inactivity timer on the basis of the successfully received PDCCH for the ON duration. During the random access procedure, a random access preamble is transmitted in one or two physical random access channel (PRACH) slots. The one or two PRACH slots are determined from among N slots corresponding to a reference slot. A subcarrier spacing (SCS) setting value for the reference slot may be 2 on the basis of the SCS setting value applied to the N slots being 5 or 6.

    Abstract: A base station according to an embodiment of the present invention may determine multiple different RA-RNTIs, and transmit message 2 for a random access response on the basis that: the base station supports not only a random access procedure of a first type terminal having a first maximum terminal bandwidth, but also a random access procedure of a second type terminal having a second maximum terminal bandwidth smaller than the first maximum terminal bandwidth; message 1 including a PRACH preamble has been detected on a PRACH resource shared between the first type terminal and the second type terminal; and at least one of PRACH preamble sequences for the first type terminal is reused for the second type terminal.
