Method, device, and system for transmitting physical uplink control channel in wireless communication system

A method for use by a user equipment (UE) in a wireless communication system, the method comprising:

• receiving semi-persistent scheduling physical downlink shared channels (SPS PDSCHs) based on SPS configurations, each of the SPS configurations including a respective maximum deferral duration;
• generating first hybrid automatic repeat request acknowledgement (HARQ-ACK) information for the SPS PDSCHs;
• determining a first physical uplink control channel (PUCCH) resource for transmitting a first PUCCH for the first HARQ-ACK information;
• and
• based on that the first PUCCH resource overlaps with a symbol unavailable for PUCCH transmission, deferring a transmission of second HARQ-ACK information to a second PUCCH on an earliest transmittable PUCCH resource after the first PUCCH resource,
• wherein the second HARQ-ACK information includes HARQ-ACK information from the first HARQ-ACK information, so that the second HARQ-ACK information corresponds to at least one first SPS PDSCH among the SPS PDSCHs, and
• wherein each of the at least one first SPS PDSCH satisfies:
• a maximum deferral duration of a corresponding SPS configuration is larger than or equal to a time difference between a slot of the second PUCCH and a slot of a respective first SPS PDSCH reception.

A base station (BS) for use in a wireless communication system, the BS comprising:

• a processor;
• and
• a communication module,
• wherein the processor is configured to:
• transmit semi-persistent scheduling physical downlink shared channels (SPS PDSCHs) based on SPS configurations, each of the SPS configurations including a respective maximum deferral duration,
• determine a first physical uplink control channel (PUCCH) resource for receiving a first PUCCH for first hybrid automatic repeat request acknowledgement (HARQ-ACK) information,
• wherein the first HARQ-ACK information is HARQ-ACK information for the SPS PDSCHs, and
• based on that the first PUCCH resource overlaps with a symbol unavailable for PUCCH reception, defer a reception of second HARQ-ACK information to a second PUCCH on an earliest receivable PUCCH resource after the first PUCCH resource,
• wherein the second HARQ-ACK information includes HARQ-ACK information from the first HARQ-ACK information, so that the second HARQ-ACK information corresponds to at least one first SPS PDSCH among the SPS PDSCHs, and
• wherein each of the at least one first SPS PDSCH satisfies:
• a maximum deferral duration of a corresponding SPS configuration is larger than or equal to a time difference between a slot of the second PUCCH and a slot of a respective first SPS PDSCH transmission.
