Abstract: The disclosure of the present specification provides a method for performing a narrowband physical uplink shared channel (NPUSCH) transmission. The method may comprise: determining a start position of the NPUSCH transmission; performing the NPUSCH transmission, if the start position of the NPUSCH transmission is determined as a first of two contiguous subframes; and postponing the NPUSCH transmission, if the start position of the NPUSCH transmission is determined as a second of the two contiguous subframes. The two contiguous subframes may be configured as a time division duplex (TDD) uplink subframe based on at least one of TDD configurations 1 and 4. The two contiguous subframes may be defined for a subcarrier spacing of 3.75 kHz.

Abstract: The present disclosure relates to a wireless access system supporting an unlicensed band, and provides a method for configuring a transmission opportunity period (TxOP) and devices for supporting the same. The method for configuring a TxOP in a wireless access system supporting an unlicensed band, according to one embodiment of the present disclosure, can comprise the steps of: performing a carrier sensing step for checking whether a secondary cell (SCell) constituted in an unlicensed band is in an idle state; transmitting a reservation signal for a predetermined amount of time if the SCell is in the idle state; and configuring a TxOP in the SCell. At this time, a start point of a first subframe (SF) included in the TxOP can be matched to a subframe, a slot or symbol boundary of a primary cell (PCell) constituted in a licensed band.
