Channel state information estimation and channel information reporting

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• receive, at a user equipment (UE) during a symbol period, at least one phase noise compensation reference signal (PC-RS) and at least one channel state information reference signal (CSI-RS);
• determine each of a first channel information indication and a second channel information indication, wherein the first channel information indication is based at least in part on both the CSI-RS and the PC-RS, and wherein the second channel information indication is based at least in part on the CSI-RS;
• and
• transmit a channel information message to a base station, the channel information message comprising a phase noise corrected channel measurement in the first channel information indication and a non-phase noise corrected channel measurement in the second channel information indication.
