Enhancement of type-1 multi-panel codebook

A method of wireless communication operable at a scheduled entity, comprising:

• receiving a reference signal;
• and
• transmitting a channel state information (CSI) report based on the reference signal, the CSI report comprising:
• a rank indicator configured to indicate one or more ranks among a plurality of ranks corresponding to a plurality of antenna panels associated with the reference signal, and
• a precoding matrix indicator (PMI) corresponding to a codebook for the plurality of antenna panels, a first antenna panel of the plurality of antenna panels having a different number of antenna ports than a second antenna panel of the plurality of antenna panels.

An apparatus for wireless communication, comprising:

• a processor;
• a transceiver communicatively coupled to the processor;
• and
• a memory communicatively coupled to the processor,
• wherein the apparatus is configured to:
• receive a reference signal;
• and
• transmit a channel state information (CSI) report based on the reference signal, the CSI report comprising:
• a rank indicator configured to indicate one or more ranks among a plurality of ranks corresponding to a plurality of antenna panels associated with the reference signal, a first rank of the plurality of ranks being different from a second rank of the plurality of ranks, and
• a precoding matrix indicator (PMI) corresponding to a codebook for the plurality of antenna panels.
