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.

Abstract: The present specification proposes a method for transmitting or receiving emergency information in a wireless communication system supporting machine type communication and a device therefor. Specifically, the method performed by a terminal may comprise the steps of: receiving discontinuous reception (DRX)-related information from a base station through radio resource control (RRC) signaling; receiving a paging message from the base station on the basis of the DRX-related information; and transmitting a physical random access channel (PRACH) preamble to the base station on the basis of the paging message emergency.

Abstract: Provided are a method and a device for a terminal monitoring a physical downlink control channel (PDCCH) in a wireless communication system. A terminal transmits, to a base station, time information notifying of a specific time, and receives, from the base station, a particular PDCCH which is used for notifying that the terminal will be monitoring a PDCCH during a time duration. The terminal monitors the PDCCH during the time duration, wherein the terminal monitors (receives) the particular PDCCH at a time which is within from the starting point of the time duration to before the specific time.
