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 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).

Abstract: The present specification provides a method for transmitting uplink data by using a preset uplink resource (PUR) in a wireless communication system. More specifically, the method, which is performed by a terminal, includes: a step for receiving setting information from a base station in an RRC connected state, the setting information being for transmitting uplink data by using the PUR in an RRC idle state; a step for transitioning from the RRC connected state to the RRC idle state; and a step for using the PUR to transmit the uplink data to the base station in the RRC idle state on the basis of the setting information.
