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: Provided are a method and apparatus for transmitting data in an unlicensed band. The device determines a downlink reception end time and an uplink transmission start time at which the uplink transmission starts in the unlicensed band. If the interval between the downlink reception end time and the uplink transmission start time is equal to or less than a threshold value, the device abandons the uplink transmission.

Abstract: The present invention relates to a wireless connection system that supports unlicensed bands. A method for performing backoff, methods for configuring a reservation signal transmission and a transmission opportunity section, and apparatus supporting the same. A method for performing a backoff operation in a wireless connection system supporting unlicensed bands, that is an embodiment of the present invention, may comprises the steps of: configuring a backoff counter N so as to perform a backoff operation; determining whether a current sub-frame is a back-off permitted section; performing a carrier sensing (CS) operation for checking if an unlicensed band is in an idle state if the sub-frame is within a backoff permitted section, for each CS unit; decreasing the backoff counter N by 1 after performing the CS operation; and transmitting a reservation signal or data using a U cell that is formed in an unlicensed band if the backoff counter value expires. In this regard, the CS operation is not performed in sub-frames except for the backoff permitted section and the backoff counter value can be maintained continuously.
