## Abstract

This disclosure provides systems, methods, and devices for wireless communication that support a channel state information (CSI) configuration. In a first aspect, a method of wireless communication includes generating, based on sensing information, an indicator that indicates a CSI recommendation. The CSI recommendation includes a recommended channel state information reference signal (CSI-RS) configuration, a recommended CSI reporting scheme, or a combination thereof. The method also includes transmitting the indicator. Other aspects and features are also claimed and described.
