Abstract: 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). 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.

Abstract: Provided are a PDCCH monitoring method and device of a DRX-configured terminal in a wireless communication system. In the method, if a monitoring occasion is present in a monitoring window for monitoring DCI (WUS) comprising a wake-up indication, the WUS is monitored in the monitoring occasion and, if the WUS is detected, the relevant operation is performed in a DRX ON duration on the basis of same. The WUS can indicate whether or not to wake up from a plurality of DRX cycles. Also, the WUS can indicate various configurations in accordance with the length of the DRX cycles. If the monitoring occasion is not present in the monitoring window, the terminal wakes up from a DRX cycle linked to the monitoring occasion and performs PDCCH monitoring for a general DCI detection not comprising a wake-up indication.
