CONFIGURATION OF INTERFERENCE MEASUREMENT RESOURCES FOR ENHANCED DOWNLINK MEASUREMENTS AND MU-MIMO
First Claim
1. A method for performing interference measurements by a user equipment (UE) in a wireless communication system, the method comprising:
- identifying a channel state information (CSI) interference measurement (IM) configuration for the UE to perform interference measurement;
determining whether or not the CSI-IM configuration includes a subset of a total number of frequency resources configured for CSI-IM in the wireless communication system;
measuring interference based on the identified CSI-IM configuration; and
sending feedback based on the measured interference.

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.
