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.

Abstract: A method and device for transmitting and receiving signals in a wireless communication system according to one embodiment of the present invention perform a 2-step or 4-step random access process in a shared spectrum. For the transmission of a PUSCH corresponding to an RAR in the 4-step random access process or a fallback-RAR in the 2-step random access process, the channel access type for the PUSCH is determined on the basis of a specific field of an RAR grant in the RAR.

Abstract: A method and an apparatus for transmitting/receiving signals in a wireless communication system, according to one embodiment of the present invention, perform a 2- or 4-step random access process in a shared spectrum. In a method for interpreting an FDRA field for PUSCH transmissions corresponding to an RAR in a 4-step random access process or a fallback RAR in a 2-step random access process, the FDRA field is truncated to its X LSB, or the FDRA field is padded with Y MSB, on the basis of whether interlace allocation for a PUSCH for access to a shared spectrum channel is provided, and the FDRA field is interpreted as the FDRA field of downlink control information (DCI) format 0_0.

Abstract: The present disclosure is related to a method, by a user equipment (UE), for transmitting uplink data through a preconfigured uplink resource (PUR) in a wireless communication system and apparatus therefor. According to the present disclosure, the method comprises, the UE receives, from a base station, PUR configuration information for uplink data transmission based on the PUR in a radio resource control (RRC) connected state; transitions from the RRC connected state to an RRC idle state; performing a timing advance (TA) update procedure based on whether a TA related to uplink transmission timing is valid; and transmits, to the base station, the uplink data on a first resource of the PUR, wherein, based on that a specific resource included in the PUR is included in a TA update performing interval, a transmission for the uplink data on the specific resource is dropped, and a value of a counter for release of the PUR is held regardless of dropping of the uplink data on the specific resource.

Abstract: The present specification provides a method whereby a terminal receives a preconfigured uplink resource from a base station, and a device for same. In particular, the method whereby a terminal receives a preconfigured uplink resource from a base station comprises: receiving a preconfigured uplink (UL) resource (PUR) configuration through RRC signaling from the base station; and if the terminal is in idle mode, transmitting uplink data to the base station by using a preconfigured uplink resource, wherein the preconfigured uplink resource comprises 12 subcarriers, the uplink data comprises a de-modulated reference signal (DMRS) sequence having a first length and including six subcarriers, and the de-modulated reference signal sequence may be transmitted using six of the 12 subcarriers.

Abstract: The present disclosure relates to a method of monitoring, by a wireless device, a downlink channel or a downlink signal. The method may include a step of receiving configuration information on a power save signal. The power saving signal can be used to signal that the downlink channel or the downlink signal should be monitored later. The configuration information may contain configuration information on an opportunity to omit the power saving signal. The method may include a step of monitoring the downlink channel or the downlink signal without monitoring the energy saving signal during the opportunity to omit. The length and/or position of the opportunity of omission can be determined according to the configuration information of a discontinuous receive cycle (DRX).
