1. A method performed by a user equipment (UE), the method comprising:
receiving a downlink control information (DCI) indicating a plurality of uplink control channel resource partitions on which an uplink control information (UCI) transmission can be transmitted, each uplink control channel resource partition of the plurality of uplink control channel resource partitions being in a bandwidth part of a respective different serving cell configured to the UE,
wherein a first serving cell respective to a first uplink control channel resource partition of the plurality of uplink control channel resource partitions is on a first frequency component carrier in an operating spectrum, and a second serving cell respective to a second uplink control channel resource partition of the plurality of uplink control channel resource partitions is on a second frequency component carrier of the operating spectrum,
wherein the operating spectrum is an unlicensed shared spectrum, and wherein the first frequency component carrier of the first serving cell and the second frequency component carrier of the second serving cell are different frequency component carriers in the unlicensed shared spectrum, and wherein the first uplink control channel resource partition and the second uplink control channel resource partition do not overlap with each other in frequency domain,
wherein the DCI includes a bitmap indicating particular frequency component carriers to which the plurality of uplink control channel resource partitions are allocated, wherein the particular frequency component carriers are selected from a larger set of frequency component carriers, wherein a respective different uplink control channel resource partition of the plurality of uplink control channel resource partitions is allocated to each frequency component carrier of the particular frequency component carriers, and wherein indicating the plurality of the plurality of uplink control channel resource partitions comprises the DCI indicating a resource index of a time-frequency control channel resource partition on which the uplink UCI transmission can be transmitted for each frequency component carrier of the particular frequency component carriers; and
transmitting the uplink UCI transmission on at least one of the plurality of uplink control channel resource partitions.
