Abstract: Methods, systems, and devices for wireless communication are described. The described techniques allow a user equipment (UE) to conserve power after transitioning from one coverage mode to another coverage mode based on power consumption estimates. The UE may make a determination on whether to modify its current extended discontinuous reception (eDRX) values by either triggering an unscheduled timing update or waiting for a scheduled timing update. For instance, the UE may estimate power consumption based on current eDRX values and the time remaining until a scheduled timing update procedure and compare this estimate to power consumption estimate based on modified eDRX values and the amount of power consumed to perform an unscheduled timing update procedure. Based on the comparison, the UE may update its eDRX values through an unscheduled TAU or through the regularly scheduled TAU procedure.
