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: 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: This specification provides a method for transmitting an NPRACH preamble in a wireless communication system supporting TDD. More specifically, the method performed by the UE includes: receiving, from a base station, NPRACH configuration information including control information for a repetition number of NPRACH preambles including symbol groups through a higher layer signaling; and transmitting, to the base station, the NPRACH preamble repeatedly through frequency hopping of a symbol group based on the NPRACH configuration information, in which a frequency location of the symbol group is determined based on a first parameter related to a start subcarrier and a second parameter related to the frequency hopping.

Abstract: The present specification discloses a method for receiving a paging signal by a wireless device which supports narrow band-Internet-of-things (NB-IoT) radio access technology (RAT). The method may comprise the steps of: receiving weights for uneven paging distribution; selecting one non-anchor PRB from a list of carriers including non-anchor physical resource blocks (PRBs) on the basis of the weights; and receiving a paging signal on the selected non-anchor PRB. Here, the non-anchor PRB allows the wireless device to assume that at least one or multiple predetermined signals are not to be transmitted, but the paging signal is to be transmitted.
