Methods and apparatus to facilitate cross-carrier beam association

An apparatus for wireless communication at a user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive, from a base station, an indication of a cross-carrier beam association associated with a first carrier and a second carrier different than the first carrier;
• determine an association between a first set of beams of the first carrier and a second set of beams of the second carrier based on the indication of the cross-carrier beam association;
• and
• receive on the first set of beams and the second set of beams based on the determined cross-carrier beam association.

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

• determining a cross-carrier beam association between a first set of beams of a first carrier and a second set of beams of a second carrier, the first carrier being different than the second carrier;
• transmitting, to a user equipment (UE), an indication of the cross-carrier beam association associated with the first carrier and the second carrier;
• and
• transmitting, to the UE, on the first set of beams and the second set of beams based on the determined cross-carrier beam association.
