Claim 0:
1. A method of wireless communication at a user equipment (UE), comprising:
receiving an indication of a cross-carrier beam association associated with a first carrier and a second carrier different than the first carrier;
selecting a first subset of beams of a first set of beams based on measurements of a transmission received on the first carrier;
transmitting a message via a second subset of beams of a second set of beams, the second subset of beams corresponding to the first subset of beams based on the cross-carrier beam association, wherein:
the transmission is a synchronization signal block (SSB) of the first set of beams,
the message is a random access channel (RACH) message,
the indication further indicates the SSB of the first set of beams is associated with a RACH occasion (RO), and
the transmission comprises transmitting the RACH message via the second subset of beams at the RO; or

receiving on the first set of beams and the second set of beams based on an association between the first set of beams of the first carrier and a second set of beams of the second carrier, said association being based on the indication of the cross-carrier beam association.
