1. A user equipment (UE), comprising:
a processor; and
a memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
receive a Secondary Cell (SCell) Activation/Deactivation MAC Control Element (MAC CE) for the SCell, the SCell Activation/Deactivation MAC CE activating the SCell,
determine whether the SCell is activated or deactivated before the UE receives the SCell Activation/Deactivation MAC CE, and
in a case that the SCell is activated before the UE receives the SCell Activation/Deactivation MAC CE, determine whether an active Bandwidth Part (BWP) of the SCell is a dormant BWP or a non-dormant BWP, the active BWP being activated before the UE receives the SCell Activation/Deactivation MAC CE,
wherein
in a case that the active BWP of the SCell is a dormant BWP, the UE does not trigger a Power Headroom Report (PHR); and
in a case that the active BWP of the SCell is not the dormant BWP, the UE triggers the PHR.
