Abstract: Methods and devices for determining application delay value of a minimum scheduling offset restriction in a wireless communication system. The method accesses a specific base station through random access, and if DCI which includes information for notifying a change in the minimum scheduling offset restriction value in slot n of the scheduling cell is to be received from the base station, applies the changed minimum scheduling offset restriction value in slot n+X of the scheduling cell. The X value can be determined based on two parameters such as Y and Z, the Y value is the minimum scheduling offset restriction value to be applied to a scheduled cell scheduled by the DCI, and the Z value is predetermined according to the subcarrier spacing of the scheduling cell. The DCI can increase, by 1, the Z value according to the temporal position at which the DCI is received within slot n.
