Abstract: The present invention relates to a wireless access system that supports an unlicensed band, and provides various methods for adjusting a contention window size, methods for determining the time when the adjusted contention window size is applied, methods for distinguishing between a collision and a channel error, and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when it is determined through the performed channel access procedure that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal through the unlicensed band; receiving hybrid automatic repeat and request acknowledgment (HARQ-ACK) information corresponding to the transmission burst; and adjusting the CWS using the number of DTX states in the HARQ-ACK information when the transmission burst is scheduled in a self-carrier scheduling scheme.

Abstract: A method and a device for transmitting an uplink transmission block in a wireless communication system are provided. Particularly, a terminal receives, from a base station, allocation information on a first grant-free uplink resource, which is scheduled semi-persistently. The terminal repeatedly transmits a first transmission block through the first grant-free uplink resource by using a first reference signal. The terminal transmits a second transmission block by using a second reference signal before completion of the transmission of the first transmission block. The second transmission block is distinguished from the first transmission block through a change of the first reference signal to the second reference signal.

Abstract: Provided are a method for managing a beam performed by a terminal in a wireless communication system and a device using the method. According to the method, the terminal performs a power saving operation on a first cell and receives a PDCCH through a second cell, wherein the PDCCH requests to measure a reference signal transmitted aperiodically in the first cell. The reference signal is received at a particular time for a DRX cycle related to the power saving operation. The terminal generates beam related information to be used in the first cell by measuring the reference signal in the first cell.

Abstract: Disclosed is a method by which a terminal transmits an acknowledgement (ACK)/negative ACK (NACK) signal in a wireless communication system. In particular, the method is characterized by receiving data from a base station, generating an ACK signal or a NACK signal corresponding to the data, transmitting the ACK signal to the base station on the basis of a first hopping pattern when the ACK signal is generated according to the data, and transmitting the NACK signal to the base station on the basis of a second hopping pattern different from the first hopping pattern when the NACK signal is generated according to the data. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, the base station or a network.
