Certain aspects of the present disclosure provide techniques for frequency tracking and timing tracking using wideband reference signals (RSs). A method that may be performed by a user equipment (UE) includes monitoring for a wideband RS from a network entity when one or more conditions are met, the wideband RS occupying a wider band of frequency resources than a tracking reference signal (TRS) transmitted by the network entity; and performing at least one of frequency tracking or timing tracking based on the monitoring.

Certain aspects relate to systems and techniques for scan control for scanning a touch panel. The scan control system can alternate adaptively between scanning the touch panel in a passive scan mode requiring minimal power and in a focused active scan mode that sequentially scans only a portion of the touch panel. The scan control system can monitor the absolute capacitance of some or all of the sensors of the touch panel in passive scan mode and can monitor the mutual capacitance of a portion of the touch panel in focused active scan mode. If the absolute capacitance of any sensor is greater than the baseline capacitance, then the scan control can use this absolute capacitance touch data to determine one or more sub-regions of the touch panel for scanning in focused active scan mode. The mutual capacitance touch data can be used for determining features of the touch event.
