Classification: CPC H | IPC H

Claim 13:
14. A user equipment (UE), comprising:
a transceiver;
memory comprising instructions; and
at least one processor configured to execute the instructions to cause the UE to:
receive, via the transceiver, 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;
select a first subset of beams of the first set of beams based on measurements of a transmission received on the first carrier;

transmit, via the transceiver, a message via a second subset of beams of the 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
receive, via the transceiver, on the first set of beams and the second set of beams based on the determined association.
