Abstract: The present invention relates to a wireless communication system and, specifically, to a method comprising the steps of: repeatedly transmitting a PUSCH; and repeatedly receiving the PDSCH in a DL duration immediately following after repeated transmission of the PDSCH, wherein when a terminal operates in an in-band mode, each PDSCH is received from an OFDM symbol subsequent to a k-th OFDM symbol in each corresponding time unit within the DL duration (k>1), and in the case where the terminal operates in a guard-band mode or a stand-alone mode, signal reception is skipped at a starting portion of the DL duration when the PDSCH is repeatedly received.

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 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 whereby user equipment operates in a wireless communication system, and a device for supporting same. Disclosed more particularly are: a method whereby, in case a base station which operates multiple analogue beams is connected to user equipment, the user equipment determines a cell-level radio link failure (RLF) and a beam-level RLF through signal transmission and reception to and from the base station and carries out an operation based on the determination; and a device for supporting said method.

Abstract: Disclosed are a method for transmitting a random access preamble in a wireless communication system supporting a narrowband-Internet of things (NB-IoT) and an apparatus therefor. Specifically, the method performed by the terminal may include: receiving, from a base station, first configuration information for a first random access preamble and second configuration information for a second random access preamble; transmitting, to the base station, the first random access preamble by using the first configuration information; and transmitting, to the base station, the second random access preamble based on the second configuration information, when transmission of the first random access preamble satisfies a predetermined criterion, in which any one of the first random access preamble and the second random access preamble may be generated based on a sequence in which all elements are not configured to 1.

Abstract: Disclosed is a method for transmitting a primary synchronization signal (PSS) by a base station in a wireless communication system. In particular, the method may comprise the steps of: dividing one symbol into multiple periods; generating multiple sequences for the PSS, the number of which is identical to the number of the multiple periods; and mapping the multiple sequences to the one symbol divided into the multiple periods, and transmitting the multiple sequences.

Abstract: Disclosed are a method for transmitting or receiving a signal to or from a base station by a terminal in a wireless communication system, and an apparatus supporting the same. More particularly, the present invention provides a configuration for transmission or reception of a signal by a terminal when an uplink signal transmission time point is dynamically determined, differently from a conventional wireless communication system which determines, as an uplink signal transmission time point, a time point after a predetermined period of time from a time point of a signal for scheduling uplink signal transmission.
