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: This specification provides a method for transmitting an NPRACH preamble in a wireless communication system supporting TDD. More specifically, the method performed by the UE includes: receiving, from a base station, NPRACH configuration information including control information for a repetition number of NPRACH preambles including symbol groups through a higher layer signaling; and transmitting, to the base station, the NPRACH preamble repeatedly through frequency hopping of a symbol group based on the NPRACH configuration information, in which a frequency location of the symbol group is determined based on a first parameter related to a start subcarrier and a second parameter related to the frequency hopping.

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.
