Interference measurements and channel state information feedback for multi-user multi-input multi-output

摘要

Methods and apparatuses for channel state information (CSI) feedback in a wireless network. In one embodiment, a method includes receiving signaling, the signaling comprising: configuring a first non-zero power (NZP) CSI-reference signal (RS) for channel measurement; Second NZP CSI-RS configuration; And CSI interference measurement (CSI-IM) configuration for interference measurement. The method includes receiving a CSI feedback request and estimating the CSI based at least on the signaled first NZP CSI-RS configuration, the second NZP CSI-RS configuration, and the CSI-IM configuration.
