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 invention provides a method for transmitting a random access preamble by a wireless device in an unlicensed band. A wireless device transmits a random access preamble, using a random access resource, and transmits a first message on a physical uplink shared channel (PUSCH). A transmission resource used to transmit the PUSCH is associated with at least one of a sequence of the random access preamble and the random access resource.

Abstract: A wireless device in an unlicensed band receives from a base station a request signal requesting initiation of downlink (DL) transmission. If carrier sensing (CS) is performed and a wireless medium idles, the wireless device transmits to the base station a response signal accepting the initiation of the DL transmission. The CS is performed with respect to a receive (RX) beam direction obtained from the request signal.

Abstract: One disclosure of the present application provides a method for a narrowband (NB) wireless device to determine whether or not to transmit a scheduling request (SR). The method may comprise a step of determining whether or not to transmit an SR by using a resource for the transmission of a hybrid automatic retransmit request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) signal. The step of determination may be performed if one or more HARQ processes are run. The resource for the HARQ ACK/NACK signal may include a narrowband physical uplink shared channel (NPUSCH).

Abstract: Disclosed is a method for transmitting an uplink signal by a terminal in a non-licensed band. In particular, the method comprises: performing a clear channel assessment (CCA) on the non-licensed band; and transmitting the uplink signal on a specific slot on the basis of the result of performing the CCA, wherein when the specific slot is a random access channel (RACH) slot, the uplink signal is transmitted on the basis of a default timing advanced (TA) value for RACH signal transmission.

Abstract: Disclosed are a method for transmitting and receiving downlink signals between a terminal and a base station in a wireless communication system supporting an unlicensed band, and a device supporting same. More specifically, as one applicable embodiment in the present disclosure, the terminal can control/change a monitoring period of a physical downlink control channel on the basis of whether a downlink signal transmission burst is transmitted from a base station, and in response thereto, the base station sets a transmission period of the physical downlink control channel in the downlink signal transmission burst so as to transmit the same to the terminal.

Abstract: Provided are: a method by which a terminal and a base station transmit/receive a signal in a wireless communication system; and a communication device using the method. The method allocates, to a plurality of antenna ports, resources for transmitting a physical uplink control channel (PUCCH) composed of two or less symbols, and transmits, to the base station, the PUCCH through the plurality of antenna ports, wherein the resources allocated to the plurality of antenna ports are multiplexed with each other.

Abstract: 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.
