Multiplexing of HARQ and CSI on PUCCH

A method of wireless communications performed by a user equipment (UE), comprising:

• receiving, from a base station (BS), a plurality of indications, wherein each indication indicates whether multiplexing of hybrid automatic retransmission request (HARQ) information and channel state information (CSI) is enabled on a corresponding physical uplink control channel (PUCCH) resource format, and wherein one or more indications of the plurality of indications indicates that multiplexing of the HARQ information and the CSI is enabled in all PUCCH resource formats in a slot based on the multiplexing of the HARQ information and the CSI being enabled in at least one selected PUCCH resource format in the slot in accordance with the one or more indications;
• generating a first CSI report regarding a first downlink (DL) channel from the BS;
• obtaining a HARQ response to a transmission from the BS;
• multiplexing the HARQ response and the first CSI report in a PUCCH, wherein the PUCCH corresponds to a first PUCCH resource format that corresponds to a first indication of the one or more indications;
• determining based on the first indication to not drop the first CSI report in the PUCCH;
• and
• transmitting the PUCCH to the BS via the first PUCCH resource format of the PUCCH resource formats.

• determining, based on a first indication of the plurality of indications, that multiplexing of the HARQ information and the CSI is enabled in all PUCCH resource formats in a slot based on the multiplexing of the HARQ information and the CSI being enabled in at least one PUCCH resource format in the slot in accordance with the first indication;
• generating a first CSI report regarding a first downlink (DL) channel from the BS;
• multiplexing a HARQ response to a transmission from the BS and the first CSI report in a PUCCH;
• and
• transmitting the PUCCH to the BS via one of the PUCCH resource formats.

A user equipment (UE), comprising:

• memory comprising instructions;
• and
• one or more processors configured to execute the instructions and cause the UE to:
• receive, from a base station (BS), a plurality of indications, wherein each indication indicates whether multiplexing of hybrid automatic retransmission request (HARQ) information and channel state information (CSI) is enabled on a corresponding physical uplink control channel (PUCCH) resource format;
• determine, based on a first indication of the plurality of indications, that multiplexing of the HARQ information and the CSI is enabled in all PUCCH resource formats in a slot based on the multiplexing of the HARQ information and the CSI being enabled in at least one PUCCH resource format in the slot in accordance with the first indication;
• generate a first CSI report regarding a first downlink (DL) channel from the BS;
• multiplex a HARQ response to a transmission from the BS and the first CSI report in a PUCCH;
• and
• transmit the PUCCH to the BS via one of the PUCCH resource formats.
