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: Provided are a method for a terminal for carrying out uplink communication in a wireless communication system, and an apparatus using the method. The method receives an uplink communication-related parameter independently configured for each analog beam, and carries out the uplink communication on the basis of the parameter. If the uplink communication is carried out using a particular analog beam, then an uplink communication-related parameter configured on the particular analog beam is applied to the uplink communication.

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.
