Abstract
Methods, systems, and devices for wireless communications are described. The network may configure a set of cells including one or more active cells and one or more deactivated cell for a user equipment (UE). The network may indicate a triggering condition and communication resources for the UE to transmit a sounding reference signal (SRS) to the deactivated cell. Based on identifying that the triggering condition has been satisfied, the UE may transmit the SRS to the deactivated cell using the indicated communication resource. The network may decode the SRS and identify updated timing advance information. The network may indicate the updated timing advance information to the UE, and accordingly, when the deactivated cell is activated, the UE may have updated timing advance information to apply to uplink transmissions to the newly activated (previously deactivated) cell.
