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 by which a terminal transmits data in an unlicensed band, and an apparatus using the method are provided. The method comprises: transmitting data to a base station through a physical uplink shared channel (PUSCH) in the unlicensed band; and receiving, from the base station, acknowledgement/negative acknowledgement (ACK/NACK) information about the data in the unlicensed band, wherein the terminal receives, from the base station, timeline information notifying of a time relationship between the PUSCH transmission time point and the ACK/NACK information reception time point.

Abstract: The present disclosure relates to a method of monitoring, by a wireless device, a downlink channel or a downlink signal. The method may include a step of receiving configuration information on a power save signal. The power saving signal can be used to signal that the downlink channel or the downlink signal should be monitored later. The configuration information may contain configuration information on an opportunity to omit the power saving signal. The method may include a step of monitoring the downlink channel or the downlink signal without monitoring the energy saving signal during the opportunity to omit. The length and/or position of the opportunity of omission can be determined according to the configuration information of a discontinuous receive cycle (DRX).

Abstract: Disclosed are a method for transmitting and receiving an uplink demodulation reference signal (DMRS) in a wireless communication system, and an apparatus therefore. Particularly, a method by which a terminal transmits a DMRS in a wireless communication system comprises the steps of: receiving, from a base station, downlink control information (DCI) for physical uplink shared channel (PUSCH) scheduling; generating a DMRS sequence for the PUSCH; and mapping the DMRS sequence to a physical resource, wherein the DMRS sequence can be mapped with the spacing of a predetermined resource element (RE) within the symbol to which the DMRS sequence is mapped.
