Abstract
The present specification suggests a method for improving performance degradation caused by frequent handovers when a terminal moves among several cells, particularly among dense small cells. To this end, required are cooperative transmission among cells and a new handover method. A base station receives RSRP information about an anchor cell and a neighboring cell and configures a cooperation-based cell cluster using the RSRP information. If RSRP values are compared and meet specific conditions, the anchor cell and the neighboring cell carry out cooperative communication. If the RSRP values of the anchor cell and an anchor candidate cell are compared during the cooperative communication and meet specific conditions, handover from the anchor cell to the anchor candidate cell is carried out. If the present invention is applied, when the terminal moves in an environment where small cells are dense, the number of handovers is greatly reduced and thus network burden can be lessened.
