Abstract: A method and device for transmitting/receiving a signal in a wireless communication system, according to one embodiment of the present invention, transmits a PUCCH including UCI. With respect to a resource for transmitting the PUCCH, the PUCCH is determined to be associated with a first interlace, among the first interlace and a second interlace, on the basis that: (i) the first interlace, and the second interlace having a higher index than that of the first interlace are configured by means of information on the PUCCH resource; and (ii) the number of physical resource blocks (PRBs) for transmitting the UCI is equal to or less than the number of PRBs of the first interlace.

Abstract: The present disclosure relates to a wireless communication system. More specifically, the present disclosure relates to: a method for transmitting a physical random access channel (PRACH) in at least one carrier from among a first carrier group on the basis of a channel sensing result, receiving a random access response (RAR) in at least one carrier from among a second carrier group in response to the transmission of the PRACH, and transmitting a physical uplink shared channel (PUSCH) on the basis of the RAR; and an apparatus therefor.

Abstract: Provided are a method for performing a random access process in an unlicensed band, and a device using the same. The device receives a random access preamble (RAP) order instructing the transmission of a RAP. The device performs a clear channel assessment (CCA) in an unlicensed cell during an RAP window so as to transmit the RAP when the device succeeds in CCA.

Abstract: A method and device for transmitting and receiving a signal in a wireless communication system, according to one embodiment of the present invention, perform a 2-step or 4-step random access process in a shared spectrum. In order to transmit a PUSCH corresponding to an RAR of the 4-step random access process or a fallback-RAR of the 2-step random access process, a channel access type for the PUSCH is determined on the basis of a specific field of an RAR grant in the RAR.

Abstract: A base station and a user equipment may determine whether to determine a start symbol value representing a start symbol of a physical downlink shared channel (PDSCH) on the basis of a reference point which is different from the start of a slot allocated for the PDSCH of a cell and is based on the subcarrier spacing of the cell and the subcarrier spacing of a scheduling cell for the cell. The base station/user equipment may transmit/receive, through the scheduling cell, the DCI including symbol information on the start symbol value for the PDSCH on the basis of the determination.

Abstract: A method by which a terminal transmits data in an unlicensed band, and an apparatus using the method are provided. The method comprises: transmitting data to a base station through a physical uplink shared channel (PUSCH) in the unlicensed band; and receiving, from the base station, acknowledgement/negative acknowledgement (ACK/NACK) information about the data in the unlicensed band, wherein the terminal receives, from the base station, timeline information notifying of a time relationship between the PUSCH transmission time point and the ACK/NACK information reception time point.
