Claim 0:
1. A method for transmitting hybrid automatic retransmission request acknowledgement (HARQ-ACK) information performed by a terminal in a wireless communication system, the method comprising:
obtaining 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;
receiving, from a base station, downlink control information (DCI) on a physical downlink control channel (PDCCH), the DCI including a HARQ feedback timing indication;
receiving, from the base station, data on a physical downlink shared channel (PDSCH) based on the DCI;
determining a first TU overlapping with a last orthogonal frequency division multiplexing (OFDM) symbol in a time slot in which the PDSCH is received;
determining a second TU based on the first TU, the HARQ feedback timing indication, and the length of the TU; and
transmitting the HARQ-ACK information for the received data on the PUCCH in the second TU.
