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: Provided are a method for performing a random access process in an unlicensed band, and a device using the same. The device receives a random access preamble (RAP) order instructing the transmission of a RAP. The device performs a clear channel assessment (CCA) in an unlicensed cell during an RAP window so as to transmit the RAP when the device succeeds in CCA.

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.
