According to the method, the UE can receive a channel state information-interference measurement (CSI-IM) configuration of first and second transmission points (TPs). Here, the CSI-IM configuration includes at least three configurations for the CSI-IM, and the at least three configurations for CSI-IM can include a first CSI-IM configuration for measuring interference to the first TP caused by the second TP, a second CSI-IM configuration for measuring interference to the second TP caused by the first TP, and a third CSI-IM configuration for measuring interference from other interference sources. Therefore, according to the channel quality reporting method, the UE can feed a channel quality indicator (CQI) measured using the first CSI-IM configuration and a CQI measured using the third CSI-IM configuration back to the first TP."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for reporting channel quality","description":"One embodiment of the present specification provides a method by which a user equipment (UE) reports channel quality.
