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: Disclosed are a method for a terminal for transmitting an uplink signal in a wireless communication system supporting an unlicensed band, and an apparatus supporting the method. The present invention includes specific examples, such as an embodiment in which, if a terminal is transmitting a signal in the direction of a particular beam, then, on the basis of the direction of a beam of a base station sharing the unlicensed band, the terminal adaptively transmits an uplink signal in the unlicensed band.

Abstract: A method for a user equipment (UE) in a wireless communication system includes monitoring a physical channel carrying downlink control information (DCI); and receiving, based on the DCI, downlink data in an unlicensed band cell (Ucell). Further, the downlink data is received in a 1st subframe of a downlink transmission burst, based on being configured to monitor the physical channel on the Ucell, the downlink data is received starting in one of a partial subframe or a normal subframe in the 1st subframe, and the partial subframe is smaller than the normal subframe.

Abstract: The present invention relates to a method for receiving a downlink signal and an apparatus therefor. Specifically, the method for receiving a downlink signal comprises the steps of: receiving first time offset information and second time offset information from a base station, wherein the first time offset information and the second time offset information each indicate the time offset between the reception time of a specific signal and the reception time of a specific channel associated with the specific signal, and the first time offset information is set to have a length shorter than that of the second time offset information; and monitoring the specific signal at a time position determined on the basis of one of the first time offset information and the second time offset information, wherein the one offset information is determined on the basis of the capability of a user device.

Abstract: A method for managing a radio link in an unlicensed band is provided. An apparatus attempts to receive a discovery reference signal (DRS) in a serving cell that is operated in the unlicensed band. The apparatus determines that a radio link to the serving cell has failed if the DRS is not received for a predetermined time.
