Harq-ack based pdsch transmission scheduled by multiple dl assignments

An apparatus of a user equipment (UE) configured for operation in a fifth-generation (5G) new radio (NR) network, the apparatus comprising:

• processing circuitry;
• and memory, wherein the processing circuitry is configured to:
• decode a first physical downlink shared channel (PDSCH) received from a generation Node B (gNB), the first PDSCH configured for downlink semi-persistent scheduling (SPS);
• generate first hybrid automatic repeat request acknowledge (HARQ-ACK) information bits based on SPS PDSCH receptions of the first PDSCH;
• when the UE is configured for deferring the HARQ-ACK information bits for the SPS PDSCH receptions of the first PDSCH (SPS HARQ-Deferral), the processing circuitry is configured to:
• determine a physical uplink control channel (PUCCH) resource in a first slot for an expected PUCCH transmission of the first HARQ-ACK information bits for the SPS PDSCH receptions that the UE would report for a first time;
• determine a PUCCH resource in an earliest second slot, after the first slot, that is available for a PUCCH transmission when the PUCCH resource in the first slot overlaps with a symbol indicated as downlink;
• and
• multiplex HARQ-ACK information bits for transmission in the PUCCH resource determined for the earliest second slot,
• wherein the multiplexed HARQ-ACK information bits include deferred HARQ-ACK information bits from the first HARQ-ACK information bits from to the SPS PDSCH receptions of the first PDSCH, and
• wherein the deferred HARQ-ACK information bits for the second slot are multiplexed when a deferral time is less than a maximum number of slots or sub-slots between the PUCCH transmission in the second slot and the SPS PDSCH receptions in a prior slot, and
• wherein the memory is configured to store the first HARQ-ACK information bits.
