Classification: CPC H | IPC H

Claim 8:
9. 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.
