Joint coding and multiplexing of deferred sps harq-ack

A base station (gNB), comprising:

• transmitting circuitry configured to transmit a first radio resource control (RRC) message comprising first information used for configuring a Semi-Persistent Scheduling (SPS) physical downlink shared channel (PDSCH) configuration,
• the transmitting circuitry configured to transmit a second RRC message comprising second information used for configuring that deferring of SPS hybrid automatic repeat request-acknowledgement (HARQ-ACK) is supported, and
• the transmitting circuitry configured to transmit, based on a transmission of a physical downlink control channel (PDCCH) carrying a downlink control information (DCI) format with cyclic redundancy check (CRC) scrambled by a first radio network identifier (RNTI) for an activation of the SPS PDSCH, the SPS PDSCH transmission;
• and
• receiving circuitry configured to receive HARQ-ACK information in a first slot/sub-slot, the receiving circuitry configured to receive a deferred HARQ-ACK information transmission in a second slot/sub-slot if the first slot/sub-slot is not available.

A method by a user equipment (UE), comprising:

• receiving a first radio resource control (RRC) message comprising first information used for configuring a Semi-Persistent Scheduling (SPS) physical downlink shared channel (PDSCH) configuration;
• receiving a second RRC message comprising second information used for configuring that deferring of SPS hybrid automatic repeat request-acknowledgement (HARQ-ACK) is supported;
• receiving, based on a detection of a physical downlink control channel (PDCCH) carrying a downlink control information (DCI) format with cyclic redundancy check (CRC) scrambled by a first radio network identifier (RNTI) for an activation of the SPS PDSCH, the SPS PDSCH transmission;
• transmitting HARQ-ACK information based on a decoding of the SPS PDSCH transmission in a first slot/sub-slot;
• and
• deferring the HARQ-ACK information transmission in a second slot/sub-slot if the first slot/sub-slot is not available.
