Method and apparatus for transmitting uplink control information

An apparatus comprising:

• a radio frequency (RF) unit for transmitting and receiving a radio signal;
• and
• a processor coupled to the RF, unit and configured to:
• receive reserved resource information that indicates a plurality of transmission-reserved subframes, each of the transmission-reserved subframes being periodically configured to transmit uplink control information,
• receive a block subframe indicator that indicates a block subframe for transmitting a signal from a relay station to a base station,
• compare the plurality of transmission-reserved subframes indicated by the reserved resource information with the block subframe indicated by the block subframe indicator,
• transmit the uplink control information in a selected transmission-reserved subframe among the plurality of transmission-reserved subframes, and
• select a transmission-reserved subframe which does not coincide with the block subframe among the plurality of transmission-reserved subframes,
• wherein the selected transmission-reserved subframe is a subframe which does not overlap with the block subframe.
