摘要:
An interference suppression method is provided. A method includes the following steps: determining, by a Femtocell, a set of Femtocells which generate interference with said Femtocell based on information measured by and feedbacked from subscribers which are served by said Femtocell, and delivering the cell IDs of all Femtocells in said set to a Femtocell gateway; establishing, by the Femtocell gateway, a relationship graph on interference among Femtocells according to information delivered from the Femtocells, and clustering the Femtocells based on said relationship graph; determining the range influenced by each Femtocell cluster; allocating resources to the Femtocells in each isolated cluster or in the range influenced by each cluster. It may ensure liable communications of Femtocell subscribers as possible, and/or may maximize spectrum efficiency and system capacity of the Femtocell layer as possible.
摘要:
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 eNodeBs of the cooperating cells in the determined candidate CoMP cooperating set; the eNodeBs being of the cooperating cell and receiving the CoMP cooperating set establishment request responding to the CoMP cooperating set establishment request to the eNodeB of the 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, decreases the overhead and complexity of the communication system and furthermore reduces the time delay in the information exchange.
