Patent ID: 8750152

Claim:
A method of transmitting CoMP feedback information at a user equipment (UE) performing CoMP (Coordinated Multi-Point) operations in a wireless communication system, the method comprising: measuring a signal intensity of a serving cell and one or more neighboring cells among CoMP cells performing the CoMP operations for the UE by using a reference signal received from the CoMP cells; measuring interference from one or more non-CoMP cells that do not perform the CoMP operations for the UE; generating a first channel quality information (CQI) regarding the serving cell and a second CQI regarding the neighboring cells among the CoMP cells based on the measured signal intensity and interference; and transmitting the generated first and second channel quality information to the serving cell, wherein the first CQI is generated based on the signal intensity of the serving cell and a time-average of the signal intensity of the neighboring cells among the CoMP cells plus the interference from the non-CoMP cells, and the second CQI is generated based on the signal intensity of the neighboring cells and the time-average of the signal intensity of the neighboring cells among the CoMP cells plus the interference from the non-CoMP cells.
