Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that includes a rule for transmitting model parameter information associated with a model for predicting a Layer 1 (L1) measurement or for transmitting a combination of the model parameter information and an L1 measurement report. The UE may transmit the model parameter information or the combination based at least in part on the rule. Numerous other aspects are described.
