1. A method of wireless communication at a user equipment (UE), comprising:
detecting a secondary cell (SCell) beam failure;
sending, to a base station via a primary cell (PCell), a scheduling request (SR) in response to detection of the SCell beam failure;
receiving, from the base station via the PCell, a first message including a trigger for an UL report; and
sending, to the base station via the PCell and separate from sending the SR, a second message comprising the UL report indicating the SCell beam failure and a preferred candidate beam associated with a SCell.
