    Abstract: Disclosed are an uplink transmission method in a wireless communication system and a device therefor. Particularly, a method for performing uplink transmission by a user equipment (UE) in an unlicensed band in a wireless communication system may comprise the steps of: sensing a channel in an entire uplink frequency band, and then sensing a channel in a predetermined resource area during a predetermined first time interval; and as a result of the channel sensing, when the channel is determined to be idle, performing uplink transmission to an eNB in an uplink resource area allocated by the eNB, wherein the uplink transmission may not be mapped in an area overlapping the predetermined resource area during a predetermined second time interval in the allocated uplink resource area.

    Abstract: A method for transmitting uplink control information at an apparatus configured with a plurality of cells including a Primary Cell (PCell) and a Secondary Cell (SCell) in a wireless communication system is discussed. The method includes receiving at least a Physical Downlink Control CHannel (PDCCH) signal indicating SPS release or a Physical Downlink Shared CHannel (PDSCH) signal with a corresponding PDCCH, and transmitting reception response information about the at least the PDCCH signal indicating SPS release or the PDSCH signal with the corresponding PDCCH through a Physical Uplink Control CHannel (PUCCH) on a subframe configured for Scheduling Request (SR) transmission.

    Abstract: The present disclosure relates to a wireless access system supporting an unlicensed band, and provides methods for transreceiving discovery reference signals and devices supporting same. A method for a terminal receiving a discovery reference signal (DRS) in a wireless access system supporting an unlicensed band, according to one embodiment of the present disclosure, may comprise the steps of: receiving an upper layer signal including parameters indicating a multimedia broadcast multicast service single frequency network (MBSFN) subframe; receiving a setting for a discovery measurement timing configuration (DMTC) section, which is a time section during which the DRS can be transmitted; and receiving the DRS within the DMTC section, wherein when a first subframe belonging to the DMTC section is configured as the MBSFN subframe and the DRS is transmitted from the first subframe, an MBSFN configuration may not be applied to the MBSFN subframe.

    Abstract: In the transmission of a narrowband positioning reference signal (NPRS), by a base station, in a cellular mobile communication system supporting narrowband-Internet of Things (NB-IoT), the base station transmits an NPRS by using a predetermined part of a sequence defined by a generation formula, which is the same as a positioning reference signal (PRS) generation formula, and when a PRS and the NPRS are transmitted through the same cell, the base station transmits, to a terminal, information indicating whether the PRS and the NPRS can be used together.
