11. An apparatus, comprising:
a transceiver which, during operation, wirelessly communicates with a network node of a wireless network; and
a processor communicatively coupled to the transceiver to perform operations comprising:
receiving, via the transceiver, a downlink control information (DCI) on a physical downlink control channel (PDCCH) configuring a carrier switching indication and a PUCCH repetition indication;
receiving, via the transceiver, downlink data on a physical downlink shared channel (PDSCH);
performing a PUCCH carrier switching or a physical uplink control channel (PUCCH) cell switching according to the carrier switching indication when transmitting uplink control information (UCI) corresponding to the downlink data; and
performing a PUCCH repetition by retransmitting the UCI according to the PUCCH repetition indication,
wherein, in performing the PUCCH carrier switching or the PUCCH cell switching, the carrier switching indication comprises a component carrier (CC) or a cell for transmitting the UCI, and
wherein, in performing the PUCCH repetition, all the retransmitted UCI are transmitted on the CC indicated in the DCI.
