HARRISON, Robert Mark
|Title:||INTERFERENCE MEASUREMENTS AND CHANNEL STATE INFORMATION FEEDBACK FOR MULTI-USER MULTIPLE-IN MULTIPLE-OUT|
Methods and apparatuses for channel state information (CSI) feedback in a wireless network. In one embodiment, a method includes receiving signaling including a first Non-Zero Power (NZP) CSI-reference signal (RS) configuration for channel measurement; a second NZP CSI-RS configuration; and a CSI interference measurement (CSI-IM) configuration for interference measurement. The method includes receiving a CSI feedback request and estimating the CSI based on at least the signaled first NZP CSI-RS configuration, the second NZP CSI-RS configuration, and the CSI-IM configuration.
