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:
cause a Medium Access Control (MAC) layer of the UE to receive, from a physical layer of the UE, a beam failure instance indication for a Secondary Cell (SCell);
increment a value of a counter by 1 for the SCell when the beam failure instance indication is received for the SCell;
compare the value of the counter for the SCell with a threshold;
trigger a Beam Failure Recovery (BFR) for the SCell when the value of the counter for the SCell is equal to or larger than the threshold; and
when the UE receives, from a base station, a MAC Control Element (CE) for deactivating the SCell or when a timer associated with the SCell expires,
deactivate the SCell, and
cancel the triggered BFR for the SCell when the SCell is deactivated.
