Abstract: A wireless device in an unlicensed band receives from a base station a request signal requesting initiation of downlink (DL) transmission. If carrier sensing (CS) is performed and a wireless medium idles, the wireless device transmits to the base station a response signal accepting the initiation of the DL transmission. The CS is performed with respect to a receive (RX) beam direction obtained from the request signal.

Abstract: Disclosed is a method for transmitting an uplink signal by a terminal in a non-licensed band. In particular, the method comprises: performing a clear channel assessment (CCA) on the non-licensed band; and transmitting the uplink signal on a specific slot on the basis of the result of performing the CCA, wherein when the specific slot is a random access channel (RACH) slot, the uplink signal is transmitted on the basis of a default timing advanced (TA) value for RACH signal transmission.

Abstract: Disclosed are methods for transmission and reception of downlink control information between a base station and a terminal, and devices for supporting same. Disclosed more particularly are: methods whereby a base station transmits downlink control information by means of an analogue beam independently determined for every one or more symbols (e.g., a unit of one or more symbols) and, in response to the base station, a terminal receives, by means of a serving beam of the terminal, the downlink control information transmitted by means of the analogue beam, which corresponds to the serving beam; and devices for supporting same.

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 and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size (CWS) in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when, as a result of performing the channel access procedure, it is determined that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal; receiving HARQ-ACK information corresponding to the transmission burst; and adjusting the CWS on the basis of the HARQ-ACK information corresponding to the first subframe of the transmission burst.

Abstract: The present invention relates to a radio access system that supports an unlicensed band, and provides methods for controlling a contention window size (CWS) for performing uplink LBT, methods for effectively utilizing a radio resource even when an uplink data transmission fails, and apparatuses supporting the same. As an embodiment of the present invention, a method for controlling a contention window size (CWS) for transmitting uplink data in a radio access system supporting an unlicensed band by a user equipment, may comprise the steps of: receiving, from an evolved node B, a radio signal including CSW control information indicating information required for controlling a CWS; controlling the CWS on the basis of the CWS control information; performing a listen before talk (LBT) process using the controlled CWS; and transmitting uplink data when a result of the LBT process shows that an unlicensed band is in an idle state.
