1. A method for wireless communication by a user equipment (UE), the method comprising:
receiving one or more channel state information reference signals (CSI-RS);
measuring the one or more CSI-RS;
generating compressed CSI feedback based on the measuring of the one or more CSI-RS, wherein the CSI feedback is compressed in a time domain (TD) using TD bases;
determining a mapping order for placing the compressed CSI feedback in one or more CSI reports; and
sending the one or more CSI reports providing the compressed CSI feedback including at least linear combination coefficients associated with the TD bases.
