Method and apparatus for transmitting control information in a wireless communication system

A method of receiving control information, which is received by a user equipment (UE) in a wireless communication system, comprising the steps of:

• receiving a data on a physical downlink shared channel (PDSCH);
• and
• transmitting a reception confirmation response for the data in a 4th following subframe from a subframe in which the data is transmitted,
• wherein if downlink control information (DCI) indicating the PDSCH is transmitted in a resource region except a resource indicated by a physical control format indication channel, the DCI is received in a subframe immediately before a subframe in which the PDSCH is received.

An eNode B in a wireless communication system, comprising:

• a transmission module;
• and
• a processor,
• the processor configured to transmit a data a data on a physical downlink shared channel (PDSCH), the processor configured to receive a reception confirmation response for the data in a 4th following subframe from a subframe in which the data is transmitted,
• wherein if downlink control information (DCI) indicating the PDSCH is transmitted in a resource region except a resource indicated by a physical control format indication channel, the DCI is transmitted in a kth preceding subframe of a subframe in which the PDSCH is transmitted.
