Methods and apparatus related to beam recovery in the secondary cell

A method of wireless communication at a base station, comprising:

• receiving, via a primary cell (PCell) from a user equipment (UE), a scheduling request (SR) based on detection of a secondary cell (SCell) beam failure at the UE;
• transmitting, from the PCell and in response to receiving the SR, a first message including a trigger for an UL report;
• and
• receiving, at the PCell from the UE and separate from receiving the SR, a second message comprising the UL report indicating the SCell beam failure and a preferred candidate beam associated with a SCell.

An apparatus for wireless communication, the apparatus comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• detect a secondary cell (SCell) beam failure;
• send, to a base station via a primary cell (PCell), a scheduling request (SR) in response to detection of the SCell beam failure;
• receive, from the base station via the PCell, a first message including a trigger for an UL report;
• and
• send, 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.
