Abstract:
A cooperative multiple point transmission and reception (CoMP) method of a user equipment (UE) receiving signals from a plurality of base stations (BSs) comprises receiving a first signal from a serving BS, receiving a second signal from an interfering BS, and restoring data, included in the first signal, using the second signal. 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. In a wireless communication system composed of multiple cells, CoMP using DPC can be performed even without data sharing between the cells.
