Abstract: The present invention provides a method by which an MTC terminal measures channel state information (CSI), a method for transmitting CSI, and apparatuses supporting the same. A method by which the MTC terminal feeds back CSI in a wireless access system supporting machine type communication (MTC), according to one embodiment of the present invention, comprises the steps of: receiving allocation information on a limited MTC bandwidth allocated to the MK terminal; calculating CSI; and feeding back the CSI. Here, the CSI can include MTC wideband channel state information (MTC W-CQI) for the limited MTC bandwidth.

Abstract: In the present invention, a part of a first demodulation reference signal sequence generated on the basis of a basic subcarrier interval (hereinafter, a first subcarrier interval) is used for a second subcarrier interval which is K times the first subcarrier interval. Values selected one for every K from among values constituting the first demodulation reference signal sequence may be used as values constituting a second demodulation reference signal sequence for the second subcarrier interval.

Abstract: A method for user equipment (UE) to receive a reference signal in a cellular mobile communication system supporting narrowband Internet of Things (NB-IoT) is disclosed. To this end, the UE receives, via at least one first subframe, a narrowband reference signal (NRS) for signal demodulating or measurement in NB-IoT and receiver, via at least one second subframe, a narrowband positioning reference signal (NPRS) for location-based measurement in the NB-IoT, wherein information on the at least one second subframe is received from a base station as configuration information of the NPRS, and, in accordance with the configuration information of the NPRS, the UE operates by assuming that the NRS is not transmitted in a subframe configured with the second subframe.
