A terminal unit for receiving a hybrid automatic retransmission request (HARQ) feedback using a frequency division duplex (FDD) frame comprises: a receiver, which receives an uplink assignment information element (A-MAP IE) for allocating each uplink through each downlink subframe of a first frame from a base station; a processor, which performs a process for transmitting uplink data that corresponds to the received A-MAP IE for allocating each uplink for a predetermined processing time: a transmitter, which transmits the processed uplink data to the base station from the respective downlink subframes having received the A-MAP IE for allocating each uplink, through each corresponding uplink subframe, after the predetermined processing time has lapsed; and a receiver, which receives, from the base station, the downlink HARQ feedback for each uplink data through each uplink subframe that has, in a third frame, the same index as the index of each downlink subframe where the A-MAP IE for allocating each uplink has been transmitted, wherein the frame is composed of 5, 6 or 7 subframes. |
