Channel state information feedback using channel compression and reconstruction

A method of wireless communication, comprising:

• transmitting, by a first network node, a reference signal (RS);
• encoding, by the first network node, channel state information (CSI) to provide encoded CSI, wherein the encoded CSI is based at least partially on the RS;
• and
• transmitting, by the first network node to a second network node, the encoded CSI in an uninterpretable payload portion of a structured payload including an interpretable payload portion that is interpretable without decoding and the uninterpretable payload portion that is uninterpretable without decoding.

An apparatus configured for wireless communication, the apparatus comprising:

• a memory;
• and
• at least one processor coupled to the memory, wherein the at least one processor is configured:
• to receive, by a first network node from a second network node, encoded channel state information (CSI) included in an uninterpretable payload portion of a structured payload including an interpretable payload portion that is interpretable without decoding and the uninterpretable payload portion that is uninterpretable without decoding;
• to generate, by the first network node, a reference signal (RS) based side information, based at least partially on a RS, wherein the RS based side information is in addition to the CSI that is configured for use in association with the CSI;
• and
• to decode, by the first network node, the encoded CSI from the uninterpretable payload portion using information from the interpretable payload portion and the RS based side information to provide reconstructed channel information.
