Abstract: The present specification provides a method for estimating a channel by a terminal in a wireless communication system supporting machine-type communication (MTC). Particularly, the terminal receives, from a base station, configuration information for receiving a cell-specific reference signal (CRS) and a dedicated demodulation reference signal (DMRS), and receives the CRS on the basis of the configuration information. The terminal then receives the DMRS and control information by means of an MTC physical downlink control channel (MPDCCH), performs channel estimation for the MPDCCH on the basis of the DMRS and the CRS, and demodulates the control information on the basis of the channel estimation, wherein one precoder among a plurality of candidate precoders applied to the CRS is applied to the DMRS.

Abstract: One disclosure of the present specification proposes a method for receiving a Narrowband Reference Signal (NRS) by a Narrow band Internet of Things (NB-IoT) device. The method may comprise receiving the NRS on at least one or more orthogonal frequency division multiplexing (OFDM) symbols. The one or more OFDM symbols are in a time division duplex (TDD) subframe. If the TDD subframe corresponds to a TDD special subframe, the one or more OFDM symbols for receiving the NRS is determined based on which TDD special subframe configuration index among a plurality of TDD special configuration indexes is used by the TDD special subframe.
