Abstract
Apparatuses and methods for indicating and performing interference measurements. A method for performing interference measurements includes identifying a CSI-IM configuration for the UE to perform interference measurement. The method includes determining whether the CSI-IM configuration includes a subset of a total number of frequency resources configured for CSI-IM in the wireless communication system. The method includes measuring interference based on the identified CSI-IM configuration. Additionally, the method includes sending feedback based on the measured interference. The method for performing interference measurements may also include determining whether to perform interference measurements based on all downlink subframes or only a portion of the downlink subframes. Additionally, the method may include performing interference measurement based on the subframe determination.
