Patent ID: 8538482

Claim:
A method for transmitting coordinated multi-point (COMP) feedback information at a serving cell in a wireless communication system, the method comprising: receiving information about channel status from a user equipment (UE); comparing the received information with a predefined threshold value, and transmitting a message to one or more neighboring cells that perform a CoMP operation, the message requesting the one or more neighboring cells to restrict use of a beam pattern group at a first subframe or subband, but not a second subframe or subband, the beam pattern group having directionality toward the serving cell, wherein the message includes the information about channel status; and receiving a response message from the one or more neighboring cells, the response message indicating that the one or more neighboring cells will restrict the use of the requested specific beam pattern group at the second subframe or subband other than the first subframe or subband, the second subframe or subband determined by the one or more neighboring cells based on the information about channel status.
