Time domain basis reporting for channel state information

A base station for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• transmit configuration information that specifies one or more parameters associated with generating, by the UE, a time domain covariance matrix specific to the UE;
• transmit a channel state information (CSI) reference signal (CSI-RS);
• and
• receive, based at least in part on the CSI-RS and the one or more parameters, a CSI report,
• the CSI report including data representing the time domain covariance matrix.

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving configuration information that specifies one or more parameters associated with generating, by the UE, a time domain covariance matrix specific to the UE;
• receiving a channel state information (CSI) reference signal (CSI-RS);
• and
• transmitting, based at least in part on the CSI-RS and the one or more parameters, a CSI report,
• the CSI report including data representing the time domain covariance matrix.
