Systems and Methods for Transmission of Uplink Control Information over Multiple Carriers in Unlicensed Spectrum

A user equipment (UE), comprising:

• at least one processor;
• and
• a non-transient memory for storing instructions that when executed by the at least one processor cause the UE to be configured to:
• receive 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 serving cell configured to the UE;
• and
• transmit the uplink UCI transmission on at least one of the uplink control channel resource partitions.

A base station, comprising:

• at least one processor;
• and
• a non-transient memory for storing instructions that when executed by the at least one processor cause the base station to be configured to:
• send to a user equipment (UE) 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 serving cell configured to the UE;
• and
• receive the uplink UCI transmission on at least one of the uplink control channel resource partitions.
