Claim:
1. A method of wireless communication, comprising: receiving, by a user equipment, a feedback configuration comprising a plurality of channel station information (CSI) processes, each CSI process of the plurality of CSI processes comprising information indicating a CSI reference signal (CSI-RS) resource of a plurality of CSI-RS resources for channel estimation and a CSI interference measurement (CSI-IM) resource of a plurality of CSI-IM resources for interference estimation, wherein each CSI-RS resource comprises a non-zero power resource and each CSI-IM resource comprises a zero power resource, and wherein the feedback configuration information is associated, through signaling from a base station, with a plurality of admissible rank value sets, where each admissible rank value set comprises at least one rank indictor (RI) and a precoding matrix indicator (PMI) pair (RI-PMI pair) and where at least one RI-PMI pair is to be reported in a CSI report; determining, for each CSI process, an admissible rank value set from the plurality of admissible rank value sets based on the signaling from the base station; determining, for each CSI process, at least one channel quality indicator (CQI) based on the CSI-RS resource, CSI-IM resource, and RI-PMI pair associated with the CSI process; and transmitting a CSI report for each CSI process of the plurality of CSI processes to the base station, the CSI report including one or more CQI of the at least one CQI and including the RI-PMI pair associated with the CSI process.
