Method and apparatus for configuring priority of UCI

1. A user equipment (UE) comprising:

one or more non-transitory computer-readable media containing computer-executable instructions embodied therein; and

at least one processor coupled to the one or more non-transitory computer-readable media, the at least one processor configured to execute the computer-executable instructions to:

receive, from a base station (BS), a first Radio Resource Control (RRC) configuration to configure a first semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH), the first RRC configuration comprising a first parameter indicating its relative priority for when the first SPS PDSCH overlaps with another SPS PDSCH in a time domain; and

receive, from the BS, a second RRC configuration to configure a second SPS PDSCH, the second SPS PDSCH overlapping the first SPS PDSCH in a time domain, the second RRC configuration comprising a second parameter indicating its relative priority for when the second SPS PDSCH overlaps with another SPS PDSCH in the time domain;

when the first SPS PDSCH and the second SPS PDSCH overlap in the time domain, prioritize one of the first SPS PDSCH and the second SPS PDSCH based on a comparison of the first parameter and the second parameter; and

generate a first uplink control information (UCI) corresponding to the prioritized SPS PDSCH.

2. The UE of claim 1 , wherein the at least one processor is further configured to execute the computer-executable instructions to:

receive, from the BS, a downlink control information (DCI) format that schedules a PDSCH reception; and

generate a second UCI in response to the PDSCH reception;

wherein the DCI format includes a field that indicates a priority of the second UCI.

3. The UE of claim 2 , wherein the first UCI and the second UCI overlap in a time domain, and the at least one processor is further configured to execute the computer-executable instructions to:

transmit, to the BS, one of the first UCI and the second UCI based on a comparison of a priority of the first UCI and the priority of the second UCI.

4. The UE of claim 1 , wherein the first UCI includes hybrid automatic repeat request acknowledgement (HARQ-ACK) information.

5. A method for wireless communication performed by a user equipment (UE), the method comprising:

receiving, from a base station (BS), a first Radio Resource Control (RRC) configuration to configure a first semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH), the first RRC configuration comprising a first parameter indicating its relative priority for when the first SPS PDSCH overlaps with another SPS PDSCH in a time domain;

receiving, from the BS, a second RRC configuration to configure a second SPS PDSCH, the second SPS PDSCH overlapping the first SPS PDSCH in a time domain, the second RRC configuration comprising a second parameter indicating its relative priority for when the second SPS PDSCH overlaps with another SPS PDSCH in the time domain;

when the first SPS PDSCH and the second SPS PDSCH overlap in the time domain, prioritizing one of the first SPS PDSCH and the second SPS PDSCH based on a comparison of the first parameter and the second parameter; and

generating a first uplink control information (UCI) corresponding to the prioritized SPS PDSCH.

6. The method of claim 5 , further comprising:

receiving, from the BS, a downlink control information (DCI) format that schedules a PDSCH reception; and

generating a second UCI in response to the PDSCH reception;

wherein the DCI format includes a field that indicates a priority of the second UCI.

7. The method of claim 6 , wherein the first UCI and the second UCI overlap in a time domain, the method further comprising:

transmitting, to the BS, one of the first UCI and the second UCI based on a comparison of a priority of the first UCI and the priority of the second UCI.

8. The method of claim 5 , wherein the first UCI includes hybrid automatic repeat request acknowledgement (HARQ-ACK) information.
