19. An apparatus for wireless communication, the apparatus comprising:
a transmitter configured to:
transmit a configuration for physical uplink control channel (PUCCH) resource sets to the at least one user equipment (UE), each of the PUCCH resource sets comprising PUCCH resources, wherein transmitting the configuration for the PUCCH resource sets comprises transmitting the configuration for the PUCCH resource sets via radio resource control signaling;
transmit signaling of an uplink control reporting indication indicating associations of the PUCCH resources with downlink demodulation reference signal (DMRS) port groups, wherein transmitting the signaling of the uplink control reporting indication comprises transmitting the uplink control reporting indication via downlink control signaling; and
transmit an indication of one or more transmit powers associated with the PUCCH resources; and
a receiver configured to receive reporting of one or more parts of uplink control information (UCI) from the UE on PUCCH resources associated with the downlink DMRS port groups for the one or more parts of the UCI also associated with the downlink DMRS ports groups based on the configuration for the PUCCH resource sets and the uplink control reporting indication.
 
20. An apparatus for wireless communication, the apparatus comprising:
a receiver configured to:
receive a configuration for physical uplink control channel (PUCCH) resource sets, each of the PUCCH resource sets comprising PUCCH resources, wherein receiving the configuration for the PUCCH resource sets comprises receiving the configuration for the PUCCH resource sets via radio resource control signaling;
receive signaling of an uplink control reporting indication indicating associations of the PUCCH resources with downlink demodulation reference signal (DMRS) port groups, wherein receiving the signaling of the uplink control reporting indication comprises receiving the uplink control reporting indication via downlink control signaling; and
receive an indication of one or more transmit powers associated with the PUCCH resources;
a processing system configured to determine the PUCCH resources associated with the downlink DMRS port groups for one or more parts of uplink control information (UCI) also associated with the downlink DMRS port groups based on the configuration for the PUCCH resource sets and the uplink control reporting indication; and
a transmitter configured to transmit the one or more parts of the UCI to at least one base station using the determined PUCCH resources and the indicated one or more transmit powers associated with the determined PUCCH resources.
