HARQ acknowledgment for semi-persistent scheduling release downlink control information

An apparatus for wireless communication at a network entity, comprising:

• one or more memories;
• and
• one or more processors coupled to the one or more memories, the one or more memories comprising instructions executable by the one or more processors to cause the network entity to:
• transmit, to a user equipment (UE), multiple semi-persistent scheduling (SPS) configurations, the multiple SPS configurations including:
• a first SPS configuration associated with a first control resource set (CORESET) group corresponding to a first transmit receive point (TRP) associated with the network entity, and
• a second SPS configuration associated with a second CORESET group corresponding to a second TRP associated with the network entity,
• the network entity being different from the first TRP and the second TRP;
• transmit, to the UE, a single downlink control information (DCI) message indicating to release the multiple SPS configurations;
• release the multiple SPS configurations in accordance with the single DCI message;
• and
• receive, from the UE and on a selected hybrid automatic repeat request (HARQ) feedback resource, HARQ feedback regarding the single DCI message, associated with a selected CORESET group that is either the first CORESET group or the second CORESET group,
• wherein the selected CORESET group is based at least in part on either:
• the selected HARQ feedback resource comprising a single physical uplink control channel (PUCCH) resource comprising either a first fixed value associated with the first CORESET group or a second fixed value associated with the second CORESET group, or
• a comparison of an index value of the first SPS configuration to an index value of the second SPS configuration.

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

• receiving from a network entity associated with a first transmit receive point (TRP) and a second TRP multiple semi-persistent scheduling (SPS) configurations,
• the multiple SPS configurations including:
• a first SPS configuration associated with a first control resource set (CORESET) group corresponding to a first transmit receive point (TRP), and
• a second SPS configuration associated with a second CORESET group corresponding to a second TRP, and
• the network entity being different from the first TRP and the second TRP;
• receiving, from the network entity, a single downlink control information (DCI) message indicating to release the multiple SPS configurations;
• releasing the multiple SPS configurations in accordance with the single DCI message;
• and
• transmitting, to the network entity and on a selected hybrid automatic repeat request (HARQ) feedback resource, HARQ feedback regarding the single DCI message, associated with a selected CORESET group that is either the first CORESET group or the second CORESET group,
• wherein the selected CORESET group is based at least in part on either:
• the selected HARQ feedback resource a single physical uplink control channel (PUCCH) resource comprising either a first fixed value associated with the first CORESET group or a second fixed value associated with the second CORESET group, or
• a comparison of an index value of the first SPS configuration to an index value of the second SPS configuration.
