wherein:
a first PUCCH resource, which corresponds to a first resource ID selected from the first set of PUCCH resource IDs for transmitting a first hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook associated with the first PUCCH-Config IE, corresponds to a low priority,
a second PUCCH resource, which corresponds to a first resource ID selected from the second set of PUCCH resource IDs for transmitting a second HARQ-ACK codebook associated with the second PUCCH-Config IE, corresponds to a high priority, and
the first set of PUCCH resource IDs and the second set of PUCCH resource IDs share no common PUCCH resource ID.
2. The UE of claim 1 , wherein the first PUCCH-Config IE and the second PUCCH-Config IE correspond to different service types.
3. The UE of claim 1 , wherein:
the first PUCCH-Config IE further indicates a first set of PUCCH spatial relation information IDs, and
the second PUCCH-Config IE further indicates a second set of PUCCH spatial relation information IDs.
4. The UE of claim 1 , wherein the one or more computer-executable instructions, when executed by the at least one processor, further cause the UE to:
receive a downlink control information (DCI) message that schedules a Physical Downlink Shared Channel (PDSCH) reception, the DCI message including a priority indicator; and
transmit HARQ-ACK information associated with the PDSCH reception in the first UL BWP after applying one of the first PUCCH-Config IE and the second PUCCH-Config IE according to the priority indicator.
5. A method performed by a user equipment (UE) for configuring Physical Uplink Control Channel (PUCCH) resources, the method comprising:
receiving a first bandwidth part (BWP) configuration associated with a first uplink (UL) BWP, the first BWP configuration including a PUCCH-ConfigList information element (IE), which includes a first PUCCH-Config IE and a second PUCCH-Config IE, the first PUCCH-Config IE indicating a first set of PUCCH resource identifiers (IDs), and the second PUCCH-Config IE indicating a second set of PUCCH resource IDs,
wherein:
a first PUCCH, which corresponds to a first resource ID resource selected from the first set of PUCCH resource IDs for transmitting a first hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook associated with the first PUCCH-Config IE, corresponds to a low priority,
a second PUCCH resource, which corresponds to a second resource ID selected from the second set of PUCCH resource IDs for transmitting a second HARQ-ACK codebook associated with the second PUCCH-Config IE, corresponds to a high priority, and
the first set of PUCCH resource IDs and the second set of PUCCH resource IDs share no common PUCCH resource ID.
6. The method of claim 5 , wherein the first PUCCH-Config IE and the second PUCCH-Config IE correspond to different service types.
7. The method of claim 5 , wherein:
the first PUCCH-Config IE further indicates a first set of PUCCH spatial relation information IDs, and
the second PUCCH-Config IE further indicates a second set of PUCCH spatial relation information IDs.
8. The method of claim 5 , further comprising:
receiving a downlink control information (DCI) message that schedules a Physical Downlink Shared Channel (PDSCH) reception, the DCI message including a priority indicator; and
transmitting HARQ-ACK information associated with the PDSCH reception in the first UL BWP after applying one of the first PUCCH-Config IE and the second PUCCH-Config IE according to the priority indicator.
9. A method performed by a base station (BS) for configuring Physical Uplink Control Channel (PUCCH) resources, the method comprising:
transmitting a first bandwidth part (BWP) configuration associated with a first uplink (UL) BWP, the first BWP configuration including a PUCCH-ConfigList information element (IE), which includes a first PUCCH-Config IE and a second PUCCH-Config IE, the first PUCCH-Config IE indicating a first set of PUCCH resource identifiers (IDs), and the second PUCCH-Config IE indicating a second set of PUCCH resource IDs,
wherein:
a first PUCCH resource, which corresponds to a first resource ID selected from the first set of PUCCH resource IDs for receiving a first hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook associated with the first PUCCH-Config IE, corresponds to a low priority,
a second PUCCH resource, which corresponds to a second resource ID selected from the second set of PUCCH resource IDs for receiving a second HARQ-ACK codebook associated with the second PUCCH-Config IE, corresponds to a high priority, and
the first set of PUCCH resource IDs and the second set of PUCCH resource IDs share no common PUCCH resource ID.

transmitting a downlink control information (DCI) message that schedules a Physical Downlink Shared Channel (PDSCH), the DCI message including a priority indicator; and
receiving HARQ-ACK information associated with the PDSCH in the first UL BWP,
wherein the priority indicator enables the UE to apply one of the first PUCCH-Config IE and the second PUCCH-Config IE for the HARQ-ACK information associated with the PDSCH.
