Abstract: A method and apparatus for performing transmission in a wireless communication system is provided. A narrowband internet-of-things (NB-IoT) user equipment (UE) transmits a physical uplink shared channel (PUSCH) to a network by using a first resource unit, and transmits an acknowledgement/non-acknowledgement (ACK/NACK) to the network by using a second resource unit. The first resource unit for PUSCH transmission consists of a first number of resource elements (REs) within a first tone in frequency domain and a first time interval in time domain. The second resource unit for ACK/NACK transmission also consists of a second number of REs within a second tone in frequency domain and a second time interval in time domain. The second number is smaller than the first number.

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: A method by which a terminal monitors a physical downlink control channel (PDCCH) in a wireless communication system, and a device therefor are provided. In the method, a terminal wakes up in a DRX cycle linked with a monitoring occasion so as to monitor a PDCCH if a wake up signal (WUS) monitoring occasion does not exist in a monitoring window for allowing the terminal to monitor the WUS.
