Secondary cell state change messaging

Abstract

Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may start a deactivation timer to determine whether to deactivate a cell. When the deactivation timer expires, the UE may deactivate the cell, such as a secondary cell (SCell), which may reduce power consumption by the UE. However, using a timer may result in inefficiencies. Various aspects relate generally to cell state change, such as for SCell activation or deactivation. For example, a UE may detect an occurrence of an event and change a state of a cell. In some aspects, the UE may activate a cell, deactivate a cell, transition to or from a lightly-activated state for a cell, or perform another cell state change action in connection with an event.
