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.
