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.

Abstract: The present specification provides a method for receiving data through interference cancellation. The method can comprise the steps of: receiving a transmission signal transmitted by a DMRS-based transmission method; detecting, from the transmission signal, a DMRS-based transmission parameter for an interference cell having caused interference in the transmission signal; estimating an interference channel for the interference cell on the basis of the detected DMRS-based transmission parameter; generating an interference signal for the interference cell on the basis of the estimated interference channel; and cancelling the generated interference signal from the transmission signal so as to restore data transmitted by a serving cell.

Abstract: The present invention provides a method for transmitting and receiving a downlink signal between a terminal and a base station in a wireless communication system supporting an unlicensed band, and a device supporting the method. As a specific example, the present invention includes a method for: transmitting and receiving a physical downlink control channel (PDCCH) signal in an unlicensed band so that a base station and a terminal transmit and receive system information associated with a particular synchronization signal/physical broadcast channel (SS/PBCH) block; and, based on the PDCCH signal, transmitting and receiving a PDSCH signal including the system information.

Abstract: One disclosure of the present application provides a method for a narrowband (NB) wireless device to determine whether or not to transmit a scheduling request (SR). The method may comprise a step of determining whether or not to transmit an SR by using a resource for the transmission of a hybrid automatic retransmit request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) signal. The step of determination may be performed if one or more HARQ processes are run. The resource for the HARQ ACK/NACK signal may include a narrowband physical uplink shared channel (NPUSCH).
