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.
