Abstract:
1. A method for transmitting an ACK/NACK signal, the method comprising: determining whether the ACK/NACK signal is repeatedly transmitted within a single transmission time interval (TTI); and transmitting the ACK/NACK signal, wherein if the determined result indicates that the ACK/NACK signal is not repeatedly transmitted, the ACK/NACK signal is transmitted to any one of sub-frames contained in the single TTI and data is transmitted to other sub-frames from among the sub-frames contained in the single TTI in consideration of information indicating whether time-frequency areas for transmitting data of other users are used or not via downlink control information, wherein if the determined result indicates that the ACK/NACK signal is repeatedly transmitted, the ACK/NACK signal is repeatedly transmitted to the individual sub-frames contained in the single TTI.
