Method and apparatus for reporting channel state information in mobile communication system

A method for receiving downlink data of a terminal in a wireless communication system, the method comprising:

• receiving information on a control channel resource on a higher layer signaling;
• receiving an indicator indicating whether the control channel resource is used or not in downlink control information;
• identifying a resource for receiving the downlink data based on the information on the control channel resource and the indicator;
• and
• receiving the downlink data on the identified resources;
• wherein when the indicator indicates that the control channel resource is used, the control channel resource is excluded from the resource for the downlink data.

A base station for transmitting downlink data in a wireless communication system, the base station comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to;
• transmit information on a control channel resource on a higher layer signaling,
• transmit an indicator indicating whether the control channel resource is used or not in downlink control information, and
• transmit the downlink data based on the information on the control channel resource and the indicator,
• wherein if the indicator indicates that the control channel resource is used, the downlink data is transmitted on a resource except the control channel resource.
