Methods, systems, and devices for wireless communication are described. For example, the described techniques provide for a base station to determine and indicate to a UE (e.g., via control signaling) a configuration for layer one (L1) reporting of non-serving cells including, for example, a number of beams or cells for which the UE is to report metrics. The UE may receive the control signaling and measure or otherwise obtain metrics for beams of a serving cell of the UE, at least one non-serving cell of the UE, or beams of a non-serving cell of the UE. The UE may also identify an index associated with at least the one non-serving cell or indices of beams of the non-serving cell which the UE may use to identify the metrics in a L1 report. Accordingly, the UE may generate and transmit an L1 report to the base station.
