An example method of wireless communication at a UE includes, after detecting a CSI report triggering event, selecting a subset of CSI-RS resources from a set of CSI-RS resources configured for the UE by applying at least one of an RSRP threshold or an SINR threshold to each CSI-RS resource of the set of CSI-RS resources. The example method also includes selecting a CSI-RS resource from the subset of CSI-RS resources based on an efficiency metric associated with each of the CSI-RS resources of the subset of CSI-RS resources. The example method also includes transmitting a CSI report to a base station, the CSI report including a CQI associated with the selected CSI-RS and at least one of a PMI, an RI, or a wideband component of the PMI."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus to facilitate dual stage channel state information reference signal (CSI-RS) selection for CSI feedback","description":"Apparatus, methods, and computer-readable media for facilitating dual stage CSI selection for CSI feedback are disclosed herein.
