Abstract: Provided are a method for accessing a channel in an unlicensed band and a device using same method. The method is configured such that a wireless device transmits data units, receives feedback information about the data units, and adjusts a contention window size used in a determination of whether there is an access to the channel in the unlicensed band on the basis of the feedback information. The wireless device can adjust the contention window size by using feedback information about, from among the data units, data units which at least partially overlap in reference duration.

Abstract: A method and device for transmitting and receiving signals 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. For the transmission of a PUSCH corresponding to an RAR in the 4-step random access process or a fallback-RAR in the 2-step random access process, the channel access type for the PUSCH is determined on the basis of a specific field of an RAR grant in the RAR.

Abstract: The present invention discloses a method for a user equipment to receive system information in a wireless communication system. Particularly, the method is characterized in detecting a first synchronization signal block configured with a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS) and a Physical Broadcasting Channel (PBCH) at a specific frequency position, determining a presence or non-presence of system information corresponding to the first synchronization signal block within a first synchronization raster corresponding to a specific frequency position based on a system information indicator included in the PBCH, and if the system information corresponding to the first synchronization signal block is determined as not existing, determining a second synchronization raster having system information exist therein based on the system information indicator.

Abstract: A terminal receives a downlink signal on the basis of a random access channel procedure (RACH procedure) in an unlicensed band. In particular, a first physical random access channel (PRACH) preamble is transmitted through message A, in response to the message A, a random access response (RAR) is received through message B related to contention resolution, information on at least one DRX timer for setting a discontinuous reception (DRX) operation is received, and a downlink signal is received during an On duration on the basis of the at least one DRX timer, wherein the first PRACH preamble is a PRACH preamble mapped to a physical uplink shared channel (PUSCH) occasion for the message A, and a window for reception of the message B may start after at least one symbol from the last symbol of the PUSCH occasion.

Abstract: A method and an apparatus for transmitting and receiving signals in a wireless communication system, according to an embodiment of the present disclosure, receive downlink control information (DCI) for uplink data transmission, perform Listen-Before-Talk (LBT) on a sub-band where a physical uplink shared channel (PUSCH) resource is located, and transmit the uplink data on the PUSCH resource on the basis of the LBT. Further, Uplink control information (UCI) for candidate physical uplink control channel (PUCCH) resources may be piggybacked on the PUSCH resource on the basis of the PUSCH resource overlapping with one or more candidate PUCCH resources from among the candidate PUCCH resources, and on the basis of a processing time, for a first candidate PUCCH resource that is the most preceding in a time domain among the candidate PUCCH resources, being equal to or greater than the minimum processing time of the terminal.
