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.

Abstract: Disclosed are a method for transmitting/receiving an uplink signal between a terminal and a base station and a device supporting same in a licensed assisted access (LAA) system in which the base station or the terminal executes listen-before-talk (LBT)-based signal transmission. Specifically, disclosed are: a method for a terminal transmitting an uplink signal by executing an uplink LBT operation which is based on LBT-related information if the base station provides the LBT-related information for the uplink LBT operation of the terminal; and a device supporting same.

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: A method of a user equipment (UE) in a wireless communication system includes receiving resource allocation information related to a configured grant (CG)-based uplink transmission, receiving configuration information indicating multiplexing between CG uplink control information (CG UCI) and hybrid automatic repeat request acknowledgement (HARQ-ACK) information, performing joint encoding of the CG UCI and the HARQ-ACK information based on the configuration information, and transmitting a CG physical uplink shared channel (CG PUSCH) based on the resource allocation information. The joint-encoded information is multiplexed in the CG PUSCH. A beta offset value corresponding to one of a first index, a second index, or a third index related to a beta offset for the HARQ-ACK information is applied to the joint encoding.
