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: A disclosure of the present specification provides a method for transmitting data by a transmitter. The method may comprise the steps of: when a transport block (TB) is divided into n data blocks, adding additional information after each of the n data blocks; and adding a cyclic redundancy check (CRC) after the last additional information. Here, the CRC may be generated on the basis of the n data blocks, and the n pieces of additional information added after each of data blocks.

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: Disclosed are a method for transmitting/receiving data in a wireless communication system supporting NarrowBand-Internet of Things (NB-IoT) and a device therefor. Specifically, a method for receiving data by a terminal may include: receiving, from a base station, Semi-Persistent Scheduling (SPS) configuration information for SPS; receiving, from the base station, an SPS control channel for delivering control information representing activation of the SPS; and receiving, from the base station, SPS data channels in specific subframes scheduled according to the SPS configuration information, in which search spaces related to the remaining SPS data channels other than a first SPS data channel among the received SPS data channels may be configured not to be monitored by the UE.

Abstract: One disclosure in the present specification presents a method for a wireless device to receive a paging message. The method may comprise: a step of deciding a wake up signal occasion (WUSO) window for attempting to receive a wake up signal (WUS); and a step of monitoring a downlink control channel during a paging window so as to attempt to receive a paging message, if the WUS is received within the decided WUSO window. Here, the WUSO window may be decided according to a duration size and offset.

Abstract: Provided are a method and an apparatus for performing a HARQ on the basis of a polar code. The apparatus generates a response bit to a transport block received by a receiver. The apparatus generates a codeword by encoding predefined information bits with a polar code. The apparatus transmits all or some bits of the codeword to the receiver over a physical channel. The response bit is located at a bit having a higher reliability among the predefined information bits. The size of the codeword is determined by a value which supports the minimum coding rate on the basis of the number of the predefined information bits.
