Abstract:
1. A method for transmitting feedback information in a CoMP (Coordinated Multi-Point) operation at a user equipment (UE), the method comprising: measuring at least one of a signal strength and an interference level for each of first cells performing the CoMP operation, by using a reference signal received from each of the first cells; measuring a sum of noise and interference levels for second cells, which do not perform the CoMP operation, by using a first region to which a reference signal of a serving cell among the first cells is transmitted; and transmitting to the serving cell, at least of: wherein data of a neighboring cell among the first cells is mapped into a region except for the first region where the reference signal of the serving cell is mapped, and wherein the reference signal of the serving cell and signals of the second cells are identified based on specific tones in the first region.
