Delayed harq-ack design under dynamic sfi

A method for wireless communications by a network entity, comprising:

• transmitting a semi-persistently scheduled (SPS) physical downlink shared channel (PDSCH) to a user equipment (UE);
• identifying a slot or subslot scheduled for the UE to report acknowledgment feedback for the SPS PDSCH;
• identifying that one or more symbols of the identified slot or subslot that are scheduled to transmit a physical uplink control channel (PUCCH) containing the acknowledgment feedback are semi-static flexible symbols;
• sending the UE a dynamic slot format indicator (SFI) dynamically configuring one or more of the semi-static flexible symbols of the slot or subslot as downlink, uplink, or flexible;
• and
• deciding whether to monitor for the acknowledgment feedback in the scheduled slot or subslot, in a subsequent slot or subslot, or both, based on the SFI.

A user equipment (UE) for wireless communications, comprising:

• at least one processor and a memory configured to
• identify a slot or subslot scheduled for reporting acknowledgment feedback for a semi-persistently scheduled (SPS) physical downlink shared channel (PDSCH);
• identify that one or more symbols of the identified slot or subslot that are scheduled to transmit a physical uplink control channel (PUCCH) containing the acknowledgment feedback are semi-static flexible symbols;
• monitor for a dynamic slot format indicator (SFI) dynamically configuring one or more of the semi-static flexible symbols of the slot or subslot as downlink, uplink, or flexible;
• and
• decide whether to report the acknowledgment feedback in the scheduled slot or subslot, in a subsequent slot or subslot, or both, based on the monitoring.
