Spatial equalization via reconfigurable intelligent surface selection

A method for wireless communications at a network entity, comprising:

• transmitting a reference signal to a user equipment (UE) via a reconfigurable intelligent surface;
• receiving, from the UE at least in part in response to the reference signal, a message comprising an indication of a value associated with a fading characteristic for a wireless link between the reconfigurable intelligent surface and the UE;
• and
• transmitting to the UE via the reconfigurable intelligent surface based at least in part on the value associated with the fading characteristic for the wireless link.

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a reference signal from a network entity via a wireless link between a reconfigurable intelligent surface and the UE;
• determine, based at least in part on the reference signal, a value associated with a fading characteristic for the wireless link;
• and
• transmit, to the network entity, a message comprising an indication of the value associated with the fading characteristic for the wireless link.
