Method for reporting channel state information in wireless access system supporting unlicensed band, and apparatus for supporting same

摘要: The present invention relates to a wireless access system supporting an unlicensed band, and provides a method for reporting channel state information (CSI) on the basis of a CSI measurement set, and apparatuses for supporting the method. The method comprising receiving an upper layer signal including CSI subframe set configuration information through a primary cell (Pcell); measuring CSI on a secondary cell (Scell) in a preoccupation access period (PAP) or a non-PAP on the basis of the CSI subframe set configuration information; and transmitting a CSI report including the measured CSI. At this time, the non-PAP is set as a first CSI subframe set, the PAP is set as a second CSI subframe set, the first CSI subframe set and the second CSI subframe set are set in the terminal through the CSI subframe set configuration information, and the Scell can be configured in an unlicensed band.
