Abstract: Disclosed is a method for receiving a downlink signal by a terminal in a wireless communication system from a base station. More particularly, a method for receiving a downlink signal comprises receiving, from a base station, information about a second reference signal being quasi co-located (QCL) and a first reference signal for demodulating a downlink signal; determining the quasi-continuity of the second reference signal on the basis of the average density of the second reference signal, which exists in a window, for determining a quasi-continuity; and receiving the downlink signal from the base station on the basis of the existence of the quasi-continuity of the second reference signal.

Abstract: A method and device for supporting a hybrid automatic repeat request (HARQ) in an unlicensed band is provided. A user equipment receives first downlink control information (DCI) including uplink scheduling information. The first DCI further includes a carrier indicator field (CIF) indicating a cell to be scheduled. If the type of the cell indicated by the CIF is a licensed cell, the format of the DCI is determined as a first DCI format including a first resource allocation (RA) field used for the uplink scheduling information. If the type of the cell indicated by the CIF is an unlicensed cell, the format of the DCI is determined as a second DCI format including a second RA field used for the uplink scheduling information.

Abstract: Embodiments of the present invention relate to a wireless access system supporting a non-licensed band and, more particularly, to methods for transmitting or receiving sub-frame length information indicating the lengths of current and next subframes, and apparatuses for supporting the same. As an embodiment of the present invention, a method for receiving sub-frame (SF) length information in a wireless access system supporting a non-licensed band may comprise the steps of: receiving a signal including first SF length information indicating the lengths of one or more of a current SF and a next SF in sub-frame number n−1 (SF #n−1); and receiving one or more of a downlink physical channel and a downlink signal in the SF #n−1 on the basis of the first SF length information. Here, the first SF length information may indicate that the current SF or the next SF is the end SF of a downlink transmission burst in the non-licensed band.
