Classification: CPC H | IPC H

Claim 7:
8. An apparatus, comprising:
a memory; and
at least one processor in communication with the memory, wherein the at least one processor is configured to:
determine a transmission power scaling according to a transmission power scaling rule rule for a physical uplink control channel configured for secondary beam failure recovery (PUCCH-BFR) transmission, wherein the PUCCH-BFR and at least one other uplink signal are multiplexed in two or more component carriers (CCs); and
transmit the PUCCH-BFR with the at least one other signal according to the transmission power scaling rule;

wherein the transmission power scaling rule includes a priority order for the plurality of uplink signals, the priority order including:
a physical random access channel (PRACH) on a primary cell having a higher priority than a physical uplink control channel (PUCCH) with hybrid automatic repeat request (HARQ) acknowledgment (ACK), a PUCCH with a scheduling request (SR), or a physical uplink shared channel (PUSCH) with HARQ-ACK;
each of the PUCCH with HARQ-ACK, the PUCCH with the SR, and the PUSCH with HARQ-ACK having a higher priority than a PUCCH with channel state information (CSI) or a PUSCH with CSI;
each of the PUCCH with CSI and the PUSCH with CSI having a higher priority than a PUSCH without HARQ-ACK or CSI; and
the PUSCH without HARQ-ACK or CSI having a higher priority than a sounding reference signal (SRS); and

wherein a priority for PUCCH-BFR is at least one of:
equivalent to the priority PUCCH with the SR; or
higher than the priority of PUCCH with the SR and lower than the priority of the PRACH on the primary cell.
