Claim 4:
5. 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.
