Document Type and Number:
WIPO Patent Application WO/2012/062166
Kind Code:
A1
Abstract:
Disclosed is a method for establishing a CoMP cooperating set in coordinated multi-point communication, the method comprising the steps of: triggering and starting a coordinated multi-point communication process; according to channel state information of all cells in a measurement cell set measured by a UE, determining a candidate CoMP cooperating set; sending a CoMP cooperating set establishment request to an eNodeB of a coordinated cell in the determined candidate CoMP cooperating set; the eNodeB being of the coordinated cell and receiving the CoMP cooperating set establishment request responding to the CoMP cooperating set establishment request to an eNodeB of a serving cell of the UE, and sending a CoMP cooperating set establishment response to the eNodeB of the serving cell of the UE; the eNodeB of the serving cell of the UE determining a CoMP cooperating set of the UE according to information of the CoMP cooperating set establishment response; and according to a coordinated multi-point communication mode, sharing data information and service bearer information of the UE of the CoMP cooperating set. The present invention guarantees coordinated multi-point joint transmission/reception, and at the same time reduces the time day in the information exchange and decreases the overhead and complexity of the communication system.
