Method, user equipment, processing device, and storage medium for transmitting harq-ack information, and method and base station for receiving harq-ack information

A user equipment (UE) comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations including:
• receiving a downlink control information (DCI) format for scheduling N physical downlink shared channel (PDSCH) receptions, where N>1;
• determining HARQ ACK hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits for the N PDSCH receptions based on the DCI format;
• and
• transmitting the HARQ-ACK information based on the HARQ-ACK information bits,
• wherein the N PDSCH receptions are divided into X PDSCH groups, where X<N, and
• wherein the transmitting of the HARQ-ACK information includes:
• transmitting HARQ-ACK information for each PDSCH group in a slot determined by applying a PDSCH-to-HARQ_feedback timing value K1 based on a last PDSCH reception in a corresponding PDSCH group.

A base station (BS) comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations including:
• transmitting a downlink control information (DCI) format for scheduling N physical downlink shared channel (PDSCH) transmissions, where N>1;
• and
• receiving hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits for the N PDSCH transmissions based on the DCI format,
• wherein the N PDSCH receptions are divided into X PDSCH groups, where X<N, and
• wherein the receiving of the HARQ-ACK information includes:
• receiving the HARQ-ACK information for each PDSCH group in a slot determined by applying a PDSCH-to-HARQ_feedback timing value K1 based on a last PDSCH transmission in a corresponding PDSCH group.
