Abstract: A method and an apparatus for transmitting/receiving signals in a wireless communication system, according to one embodiment of the present invention, perform a 2- or 4-step random access process in a shared spectrum. In a method for interpreting an FDRA field for PUSCH transmissions corresponding to an RAR in a 4-step random access process or a fallback RAR in a 2-step random access process, the FDRA field is truncated to its X LSB, or the FDRA field is padded with Y MSB, on the basis of whether interlace allocation for a PUSCH for access to a shared spectrum channel is provided, and the FDRA field is interpreted as the FDRA field of downlink control information (DCI) format 0_0.

Abstract: Disclosed is a method for a terminal to transmit a Physical Uplink Shared Channel (PUSCH) in a wireless communication system. In particular, the disclosed method is characterized by comprising the steps of: receiving an uplink (UL) grant for scheduling a Dynamic Grant (DG)-PUSCH; transmitting a Configured Grant (CG)-PUSCH; and transmitting the DG-PUSCH on the basis of the UL grant, wherein the DG-PUSCH is transmitted without gaps after the transmission of the CG-PUSCH on the basis of first frequency resources for the DG-PUSCH being the same as second frequency resources for the CG-PUSCH, or the first frequency resources being a sub-set of the second frequency resources.

Abstract: Provided are a method of performing a channel access procedure by an apparatus in an unlicensed band, and an apparatus using same method. The apparatus determines a contention window size (CWS) and performs a channel access procedure with respect to a first channel on the basis of the determined contention window size. The contention window size may be adjusted on the basis of feedback information relating to a second channel. When a transmission history of the second channel, which is to be reflected in determining the contention window size, does not exist, the contention window size may be determined to be a minimum CWS value in a specific channel access priority class.

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.
