Claim 16:
17. A method of wireless communication at a base station, comprising:
transmitting an indication of 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 a first set of transmissions via at least a first subset of beams of the first set of beams;
receiving a message via a second subset of beams of the second set of beams, wherein the first subset of beams is based on the first set of transmissions and the second subset of beams corresponds to the first subset of beams based on the cross-carrier beam association, wherein:
the reception 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 that SSB of the first set of beams is associated with a RACH occasion (RO), and
the reception comprises receiving the RACH message via the second subset of beams at the RO; or

transmitting on the first set of beams and the second set of beams based on the cross-carrier beam association.
