Providing acknowledgement/negative acknowledgement (ack/nack) feedback for downlink semi-persistent scheduling (sps) with sub-slot periodicity

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

• receiving a configuration that indicates a sub-slot periodicity for downlink semi-persistent scheduling (SPS);
• receiving a plurality of transmissions within a single slot according to the sub-slot periodicity;
• and
• transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with receiving the plurality of transmissions within the single slot based at least in part on a HARQ-ACK feedback scheme associated with the downlink SPS.

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

• memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• receive a configuration that indicates a first sub-slot periodicity for downlink semi-persistent scheduling (SPS);
• receive a plurality of transmissions according to the first sub-slot periodicity in a first slot, wherein the first sub-slot periodicity enables receiving the plurality of transmissions within a single slot;
• and
• transmit hybrid automatic repeat request acknowledgement (HARQ-ACK) information in a second slot, wherein the second slot includes a plurality of physical uplink control channels (PUCCH) with a second sub-slot periodicity, and wherein the HARQ-ACK information is associated with the plurality of transmissions.
