Abstract: A method is provided for reporting feedback information of Multicast-Broadcast Single-Frequency Network (MBSFN) transmission by a user equipment in a wireless communication system. The user equipment receives configuration information for feedback information of the MBSFN transmission when the user equipment receives signals from a plurality of base stations based on the MBSFN transmission, and transmits the feedback information measured in a resource region according to the configuration information. The user equipment receives a common reference signal (CRS) of an antenna port 0 of an interference cell from the interference cell in an MBSFN area, and the feedback information is measured in the resource region considering a position of a symbol allocated the CRS of the antenna port 0 of the interference cell.
