Abstract: Provided are a method for determining a point in time for applying a changed minimal scheduling offset in a wireless communication system, and a device for applying the method. The method comprises the steps of: receiving, in slot n of a scheduling cell, first DCI comprising information for informing a change in a K2min value which is a minimal scheduling offset; receiving second DCI based on the changed K2min value after slot n+X of the scheduling cell; and transmitting a PUSCH scheduled by the second DCI. The value of X is determined on the basis of: K0min which is a minimal scheduling offset currently applied to a scheduled cell scheduled by the first DCI; a subcarrier interval setting of the scheduling cell; a subcarrier interval setting of the scheduled cell; a value predetermined dependently on a subcarrier interval of the scheduling cell; etc.

Abstract: A method and an apparatus for monitoring a PDCCH of a terminal in a wireless communication system are provided. A terminal is connected to a base station through initial access. Next, first configuration information, which notifies of a monitoring occasion for detecting a first DCI including information notifying whether the terminal wakes up, is received from the base station, and monitoring for detecting the first DCI is performed during the monitoring occasion. If the first DCI has not been detected in the monitoring occasion, whether PDCCH monitoring for detecting a second DCI is performed in the next DRX-on section is determined on the basis of second configuration information indicating an operation to be applied to the terminal when the terminal has not detected the first DCI.

Abstract: A method of monitoring a control signal in a wireless communication system, where the method is performed by a user equipment (UE) and includes: selecting at least one control resource set (CORESET) among a plurality of CORESETs based on an overlap between physical downlink control channel (PDCCH) monitoring occasions in the plurality of CORESETs; and monitoring a PDCCH only in the selected at least one CORESET, among the plurality of CORESETs. The method also includes: based on the at least one CORESET including a first CORESET, and based on a first reference signal of the first CORESET and a second reference signal of a second CORESET being associated with a same synchronization signal/physical broadcast channel block (SSB): monitoring the PDCCH in both the first CORESET and the second CORESET.

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.
