摘要： 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.

摘要： This specification provides a method for transmitting a random access preamble by a user equipment (UE) in a wireless communication system supporting a narrow band-Internet of things (NB-IoT). Specifically, the UE receives a downlink control channel (Physical Downlink Control Channel (PDCCH)) including downlink control information (DCI) from an eNB and the DCI includes an indicator indicating whether a preamble format of a random access preamble allocated to the UE is format 0/1 or format 2. Then, the UE transmits the random access preamble to the eNB in a subcarrier allocated to the UE according to the preamble format and receives a random access response from the eNB in response to the random access preamble.

摘要： 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.

摘要： Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.

摘要： In the present invention, a method for performing an uplink transmission in a wireless communication system and an apparatus for supporting the same are disclosed. Particularly, a method for transmitting an uplink control channel in a wireless communication system by a terminal may comprise receiving, from a base station, beam information regarding one or more beams for transmitting a physical uplink control channel (PUCCH), via a radio resource control (RRC) signaling; receiving, from the base station, beam indication information indicating a specific beam among the one or more beams using a medium access control-control element (MAC-CE); and transmitting, to the base station, the physical uplink control channel using the specific beam.

摘要： One disclosure of the present specification proposes a method for receiving a Narrowband Reference Signal (NRS) by a Narrow band Internet of Things (NB-IoT) device. The method may comprise receiving the NRS on at least one or more orthogonal frequency division multiplexing (OFDM) symbols. The one or more OFDM symbols are in a time division duplex (TDD) subframe. If the TDD subframe corresponds to a TDD special subframe, the one or more OFDM symbols for receiving the NRS is determined based on which TDD special subframe configuration index among a plurality of TDD special configuration indexes is used by the TDD special subframe.
