Method and apparatus for cooperative multiple point transmission and reception

A method of performing CoMP in a wireless communication system, comprising:

• an interfering BS acquiring DPC information of a serving cell and interference channel information;
• the interfering BS generating a dummy signal which will be transmitted to a UE placed in the serving cell, based on the DPC information and the interference channel information;
• and
• the interfering BS transmitting a downlink signal to a UE connected to the interfering BS and simultaneously broadcasting the dummy signal,
• wherein the interference channel information is information about a channel between the interfering BS and the UE placed in the serving cell, and the dummy signal is used to cancel interference of the downlink signal with the UE placed in the serving cell.

A UE, comprising:

• an RF (Radio Frequency) for transmitting or receiving a radio signal;
• and
• a processor coupled to the RF unit,
• wherein the processor receives a first signal from a serving BS, receives a second signal from an interfering BS, and restores data, included in the first signal, using the second signal, and
• the second signal comprises a downlink signal, transmitted from the interfering BS to a UE connected to the interfering BS, and a dummy signal for canceling interference of the downlink signal with the first signal.
