1. A method for transmitting control information of a base station in a time division duplex (TDD) system using a single carrier, the method comprising:

  • setting a transmit power control (TPC) command for controlling physical uplink control channel (PUCCH) transmission power of a PUCCH and acknowledgement (ACK)/not-acknowledgement (NACK) resource indicating information indicating resources for transmitting a hybrid automatic repeat request (HARQ) ACK/NACK signal on the PUCCH, in an uplink (UL) subframe; and

    transmitting at least one of the TPC command and the ACK/NACK resource indicating information on a physical downlink control channel (PDCCH) in downlink (DL) subframes corresponding to the UL subframe,wherein the HARQ ACK/NACK signal for the DL subframes corresponding to the UL subframe is transmitted on the PUCCH using a PUCCH format 3,the TPC command is transmitted on the PDCCH in at least one of the DL subframes corresponding to the UL subframe, andthe ACK/NACK resource indicating information is transmitted using bits allocated in order to transmit the TPC command on the PDCCH in the DL subframes in which the TPC command is not transmitted among the DL subframes corresponding to the UL subframe.
