Abstract: A wireless communication system is disclosed. More particularly, disclosed herein are a method including receiving downlink scheduling information on a PDCCH, the downlink scheduling information comprising resource indication information (RI), selecting a first PUCCH resource set from among a plurality of PUCCH resource sets based on a size of the control information, and transmitting the control information using a PUCCH resource corresponding to the RI in the first PUCCH resource set, wherein, when a control information size supported by the first PUCCH resource set is less than or equal to X (>=1) bits, the PUCCH resource is determined using one of a first scheme and a second scheme, and wherein, when the control information size supported by the first PUCCH resource set is greater than X bits, the PUCCH resource is determined using only the second scheme, and an apparatus therefor.

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: Disclosed are a method for transmitting and receiving downlink signals between a terminal and a base station in a wireless communication system supporting an unlicensed band, and a device supporting same. More specifically, as one applicable embodiment in the present disclosure, the terminal can control/change a monitoring period of a physical downlink control channel on the basis of whether a downlink signal transmission burst is transmitted from a base station, and in response thereto, the base station sets a transmission period of the physical downlink control channel in the downlink signal transmission burst so as to transmit the same to the terminal.

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: Provided are a method and a device for reporting a power headroom in a wireless communication system. The device receives initial downlink control information (DCI) for physical uplink shard channel (PUSCH) transmission in a first subframe and receives triggering DCI in a second subframe. The device calculates a power headroom on the assumption that the PUSCH transmission is not performed.
