Abstract: Disclosed are a method for a base station and a UE transmitting/receiving a signal in a wireless communication system, and a device supporting same. According to one embodiment, a method for a UE transmitting/receiving a signal in a wireless communication system comprises the steps of: receiving, from a base station, configuration information about a carrier for one or more channel; and, on the basis of the received configuration information, transmitting and then receiving one or more channel. Therein, the one or more channel comprises at least one among a downlink control channel, a downlink shared channel and an uplink shared channel, and the carrier may be configured differently based on the channel being transmitted therethrough.

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: One disclosure of the present specification provides a method for receiving a downlink physical channel by a narrowband Internet of things (NB-IoT) device. The method may comprise the steps of: determining whether to receive a signal of a downlink physical channel from an NB-IoT cell, on a downlink pilot time slot (DwPTS) of a time division duplex (TDD) special subframe; and receiving the signal of the downlink physical channel on the TDD special subframe including the DwPTS, on the basis of the determination.

Abstract: This specification provides a method for transmitting a random access preamble by a user equipment (UE) in a wireless communication system supporting a narrow band-Internet of things (NB-IoT). Specifically, the UE receives a downlink control channel (Physical Downlink Control Channel (PDCCH)) including downlink control information (DCI) from an eNB and the DCI includes an indicator indicating whether a preamble format of a random access preamble allocated to the UE is format 0/1 or format 2. Then, the UE transmits the random access preamble to the eNB in a subcarrier allocated to the UE according to the preamble format and receives a random access response from the eNB in response to the random access preamble.

Abstract: The present invention relates to a wireless communication system and, specifically, to a method comprising the steps of: repeatedly transmitting a PUSCH; and repeatedly receiving the PDSCH in a DL duration immediately following after repeated transmission of the PDSCH, wherein when a terminal operates in an in-band mode, each PDSCH is received from an OFDM symbol subsequent to a k-th OFDM symbol in each corresponding time unit within the DL duration (k>1), and in the case where the terminal operates in a guard-band mode or a stand-alone mode, signal reception is skipped at a starting portion of the DL duration when the PDSCH is repeatedly received.
