摘要
Certain aspects of the present disclosure provide methods and apparatus for performing coordinated multipoint (CoMP) channel state information (CSI) feedback under multiple channel and interference assumptions. One method generally includes receiving signaling indicating at least one or more interference measurement resources (IMRs) from a network and a configuration with one or more non-zero power reference signal (NZP-RS) resources in which one or more base stations transmit a RS, performing separate interference measurements at least on a per-IMR basis in one or more subframes by forming a baseline interference estimate based on the IMR and forming separate interference estimates based on adding interference from selected NZP-RS resources to the baseline interference estimate, and transmitting one or more CSI feedback reports that correspond to the interference measurements.
