Method, apparatus for transmitting HARQACK information, electronic device and storage medium

A terminal for transmitting hybrid automatic retransmission request acknowledgement (HARQ-ACK) information in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a processor configured to:
• obtain information on a length of a time unit (TU) for a physical uplink control channel (PUCCH) the TU being a part of a time slot;
• receive, from a base station, downlink control information (DCI) on a physical downlink control channel (PDCCH) the DCI including a HARQ feedback timing indication;
• receive, from the base station, data on a physical downlink shared channel (PDSCH) based on the DCI;
• determine a first TU overlapping with a last orthogonal frequency division multiplexing (OFDM) symbol in a time slot in which the PDSCH is received;
• determine a second TU based on the first TU, the HARQ feedback timing indication, and the length of the TU;
• and
• transmit the HARQ-ACK information for the received data on the PUCCH in the second TU.

A method for transmitting hybrid automatic retransmission request acknowledgement (HARQ-ACK) information performed by a base station in a wireless communication system, the method comprising:

• transmitting information on a length of a time unit (TU) for a physical uplink control channel (PUCCH), the TU being a part of a time slot;
• transmitting, to a terminal, downlink control information (DCI) on a physical downlink control channel (PDCCH), the DCI including a HARQ feedback timing indication;
• transmitting, to the terminal, data on a physical downlink shared channel (PDSCH) based on the DCI;
• and
• receiving, the HARQ-ACK information for the transmitted data on the PUCCH in a second TU,
• wherein a first TU is a TU overlapping with a last orthogonal frequency division multiplexing (OFDM) symbol in a time slot in which the PDSCH is transmitted, and
• wherein the second TU is based on the first TU, the HARQ feedback timing indication, and the length of the TU.
