Method for terminal resending data in wireless communication system, and communication device using same

A user equipment (UE) for receiving hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information in a wireless communication system, the UE comprising:

• at least one transceiver for transmitting and receiving radio signals;
• and
• at least one processor for controlling the at least one transceiver,
• wherein the at least one processor configured to:
• receive, from a base station, downlink control information (DCI) including a flag, HARQ-ACK information and a transmission power control (TPC) command for a physical uplink shared channel (PUSCH) scheduled by the DCI, wherein the DCI is used for indicating downlink feedback information to the UE based on the flag in the DCI,
• wherein the HARQ-ACK information relates to a plurality of HARQ process indexed,
• wherein the HARQ-ACK information comprises a plurality of bits,
• wherein the plurality of HARQ process indexes are mapped in ascending order form the first bit to the last bit of the plurality of bits.
