Estimation of channel state information for non-sounded panels or subpanels based on sounded panels or subpanels

A network entity for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive a sounding reference signal (SRS) at a panel of a multi-panel system of the network entity, wherein the panel includes one or more sounded subpanels and one or more non-sounded subpanels;
• estimate a channel to obtain channel state information (CSI) for the one or more sounded subpanels based at least in part on the SRS;
• estimate CSI for the one or more non-sounded subpanels of the panel based at least in part on the CSI for the one or more sounded subpanels;
• and
• transmit or receive a communication based at least in part on the CSI for the one or more sounded subpanels and the CSI for the one or more non-sounded subpanels.

A network entity for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive a sounding reference signal (SRS) at a multi-panel system of the network entity;
• estimate a channel for the multi-panel system using intra-panel sub sampling or inter-panel sub sampling;
• and
• transmit or receive a communication based at least in part on the estimating the channel.
