PROBLEM TO BE SOLVED: To suppress a frequent occurrence of a handover.SOLUTION: In a small cell base station 3, an eICIC determination part 14 determines an execution state of an eICIC between a macro cell and a small cell performed by a macro cell base station A communication control part 15 obtains a first outgoing reception power in the small cell at the time of non-execution of eICIC and a second outgoing reception power in the small cell at the time of the execution of the eICIC. Further, the communication control part 15 estimates a CRE off-set value to be set to the small cell by the macro cell base station based on a first reception power and a second reception power. The communication control part 15 controls an outgoing reception power value in a user terminal based on the estimated CRE off-set value.SELECTED DRAWING: Figure 2 |
