1. A method of wireless communication performed at a user equipment (UE), comprising:
receiving configuration information that indicates a plurality of channel state information reference signal (CSI-RS) resources associated with a CSI-RS;
using a measurement-based approach based on not receiving an explicit indication that indicates the CSI-RS was transmitted using one of the plurality of CSI-RS resources, wherein using the measurement-based approach comprises:
measuring one or more CSI-RS resources of the plurality of CSI-RS resources; and
selecting one of the plurality of CSI-RS resources based on the measurement of the one or more CSI-RS resources; and
transmitting, based on a particular signal strength value of the selected one of the plurality of CSI-RS resources, a CSI report that includes channel state information (CSI) or other information associated with the CSI-RS.
