Method for transmitting control signal to relay node at base station in mimo wireless communication system and apparatus therefor

A method for transmitting data at a transmitting end in a multi-input multi-output (MIMO) wireless communication system, the method comprising:

• allocating transmission resources to the data per basic resource allocating unit comprising a predetermined number of resource element;
• and
• transmitting the data to a receiving end using the allocated transmission resources,
• wherein the resource element is defined by one symbol and one subcarrier corresponding to the one symbol,
• wherein the resource element included in the basic resource allocating unit corresponds to the same symbol, and
• wherein the transmission resources allocated to the data do not include resource elements corresponding to symbols including channel state information-reference signals (CSI-RSs).

A transmitting apparatus in a multi-input multi-output (MIMO) wireless communication system, the transmitting apparatus comprising:

• a processor for allocating transmission resources to data per basic resource allocating unit comprising a predetermined number of resource element;
• and
• a transmitting module for transmitting the data to a receiving end using the allocated transmission resources,
• wherein the resource element is defined by one symbol and one subcarrier corresponding to the one symbol,
• wherein the resource element included in the basic resource allocating unit corresponds to the same symbol, and
• wherein the transmission resources allocated to the data do not include resource elements corresponding to symbols including channel state information-reference signals (CSI-RSs).
