Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a set of synchronization signal block (SSB) measurements and select a serving UE beam and a set of candidate UE beams for measuring a channel state information (CSI) reference signal (CSI-RS) based on the set of SSB measurements. The UE may identify, or predict, time resources for the CSI-RS based on previous CSI-RS configurations. The UE may measure the CSI-RS based on the time resources using a candidate UE beam from the set of candidate UE beams. The UE may transmit, to an access network entity, a measurement report based on measuring the CSI-RS using the candidate UE beam or a last CSI-RS measurement on the serving UE beam.
