Abstract: Provided are a method and device for determining an application delay value of a minimum scheduling offset limit in a wireless communication system. In the method, when DCI including information notifying a change in a minimum scheduling offset limit value in slot n of a scheduling cell is received, the changed minimum scheduling offset limit value is applied in slot n+X of the scheduling cell. Here, the X value may be determined on the basis of two parameters such as Y and Z, wherein the Y value is a minimum scheduling offset limit value applied to a scheduled cell scheduled by the DCI, and the Z value is a value determined in advance according to a subcarrier interval of the scheduling cell. In addition, the Z value may be increased by 1 according to the temporal position at which the DCI is received in the slot n.

Abstract: The present specification discloses an invention relating to a method for transmitting an MTC physical downlink control channel (MPDCCH) by a base station in a wireless communication system supporting machine type communication (MTC). According to the present invention, a base station transmits, to a terminal, configuration information related to the transmission of an MPDCCH and maps the MPDCCH onto multiple resource elements (REs) of at least one first symbol constituting a first slot of a special subframe. The special subframe is a subframe in which, among symbols constituting the subframe, the number of symbols for data transmission is smaller than or equal to a predetermined number. The base station transmits the MPDCCH to the terminal over the multiple resource elements, wherein the mapping step is performed by copying at least one second symbol of a second slot adjacent to the first slot onto the at least one first symbol.
