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: A user equipment (UE) may determine a first transmission time for a first hybrid automatic repeat request acknowledgement (HARQ-ACK) for a first downlink channel associated with a first HARQ process; and receive a second downlink channel associated with the first HARQ process. Receiving the second downlink channel for the first HARQ process may include: receiving the second downlink channel after the first transmission time based on the first HARQ-ACK being not subject to HARQ deferral; and receiving the second downlink channel after a second transmission time based on the first HARQ-ACK being subject to the HARQ deferral and the first transmission time being determined by the HARQ deferral from the second transmission time earlier than the first transmission time.

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.
