1. A user equipment (UE) for wireless communication, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, individually or collectively configured to:
receive a configuration of a first hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook and a second HARQ-ACK codebook,
wherein the configuration of the first HARQ-ACK codebook and the second HARQ-ACK codebook indicates that physical uplink control channel (PUCCH) carrier switching is enabled for at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook;
receive an indication of a PUCCH carrier switch for the at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook,
wherein the one or more processors, to receive the indication of the PUCCH carrier switch, are configured to:
receive a configuration of a time pattern for switching a target PUCCH carrier between a first carrier and a second carrier, wherein the time pattern applies to the first HARQ-ACK codebook and the second HARQ-ACK codebook;
receive at least one downlink communication associated with the at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook; and
transmit HARQ feedback for the at least one downlink communication in the at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook on the target PUCCH carrier based at least in part on the indication of the PUCCH carrier switch.
