Downlink assignments for downlink control channels

A user equipment (UE), comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the UE to:
• determine a physical uplink control channel (PUCCH) resource in response to physical downlink control channel (PDCCH) reception associated with a downlink control information (DCI) format, wherein:
• the PDCCH reception comprises a first PDCCH candidate associated with a first search space set and a second PDCCH candidate associated with a second search space set;
• the first search space set is associated with a first control resource set (CORESET) and the second search space set is associated with a second CORESET;
• the first CORESET and the second CORESET are different;
• and
• the PUCCH resource is determined based at least in part on determining a third CORESET, wherein the third CORESET is a CORESET selected from the first CORESET and the second CORESET based on index values of the first CORESET and the second CORESET;
• provide hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with the first PDCCH candidate and the second PDCCH candidate in a PUCCH transmission in the determined PUCCH resource.

A method performed by a user equipment (UE), the method comprising:

• determining a physical uplink control channel (PUCCH) resource in response to physical downlink control channel (PDCCH) reception associated with a downlink control information (DCI) format, wherein:
• the PDCCH reception comprises a first PDCCH candidate associated with a first search space set and a second PDCCH candidate associated with a second search space set;
• the first search space set is associated with a first control resource set (CORESET) and the second search space set is associated with a second CORESET;
• the first CORESET and the second CORESET are different;
• and
• the PUCCH resource is determined based at least in part on determining a third CORESET, wherein the third CORESET is a CORESET selected from the first CORESET and the second CORESET based on index values of the first CORESET and the second CORESET;
• providing hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with the first PDCCH candidate and the second PDCCH candidate in a PUCCH transmission in the determined PUCCH resource.

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and configured to cause the processor to:
• determine a physical uplink control channel (PUCCH) resource in response to physical downlink control channel (PDCCH) reception associated with a downlink control information (DCI) format, wherein:
• the PDCCH reception comprises a first PDCCH candidate associated with a first search space set and a second PDCCH candidate associated with a second search space set;
• the first search space set is associated with a first control resource set (CORESET) and the second search space set is associated with a second CORESET;
• the first CORESET and the second CORESET are different;
• and
• the PUCCH resource is determined based at least in part on determining a third CORESET, wherein the third CORESET is a CORESET selected from the first CORESET and the second CORESET based on index values of the first CORESET and the second CORESET;
• provide hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with the first PDCCH candidate and the second PDCCH candidate in a PUCCH transmission in the determined PUCCH resource.

An apparatus for performing a network function, the apparatus comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the apparatus to:
• assign a first index to a first control resource set (CORESET), and a second index to a second CORESET;
• schedule a downlink (DL) transmission for a user equipment (UE);
• receive a hybrid automatic repeat request acknowledgement (HARQ-ACK) corresponding to the scheduled DL transmission in a physical uplink control channel (PUCCH) resource, wherein the PUCCH resource is determined based on the first index and the second index.
