Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit assistance information to a base station to request an update or a modification to one or more communication parameters configured at the UE. Such communication parameters may include a quantity of uplink multiple-input multiple-output (MIMO) layers, a quantity of downlink MIMO layers, a minimum scheduling offset, a maximum quantity of component carriers, or a maximum aggregated bandwidth for a secondary cell group (SCG). In some implementations, the UE may transmit the assistance information requesting the update or modification to one or more of such communication parameters based on detecting that the UE satisfies one or more triggering conditions or thresholds.
