Abstract: A method is provided for computing a channel quality indicator (CQI) value by a user equipment in a wireless communication system. Channel status information-reference signal (CSI-RS) resources and zero power CSI-RS resources are configured through a higher layer. The CQI value is computed based on a channel measurement and an interference measurement. The channel measurement is performed by using the CSI-RS resources and the interference measurement is performed by using the zero power CSI-RS resources. If two CSI subframe sets are configured, the interference measurement for one CSI subframe set of the two CSI subframe sets is performed by using the zero power CSI-RS resources within a subframe subset belonging to the one CSI subframe set.

Abstract: The present disclosure relates to a wireless access system supporting an unlicensed band, and provides a method for configuring a transmission opportunity period (TxOP) and devices for supporting the same. The method for configuring a TxOP in a wireless access system supporting an unlicensed band, according to one embodiment of the present disclosure, can comprise the steps of: performing a carrier sensing step for checking whether a secondary cell (SCell) constituted in an unlicensed band is in an idle state; transmitting a reservation signal for a predetermined amount of time if the SCell is in the idle state; and configuring a TxOP in the SCell. At this time, a start point of a first subframe (SF) included in the TxOP can be matched to a subframe, a slot or symbol boundary of a primary cell (PCell) constituted in a licensed band.
