In a terminal that judges whether to trigger a handover from a serving cell to another cell, a RSRQ/RSRP measurer measures a first received quality value by using a cell-specific reference signal transmitted from the neighboring cell or a second received quality value by using a cell-detection reference signal transmitted from the neighboring cell. An offset adder calculates a third received quality value by adding an offset value to the second received quality value. A judging circuitry judges whether the first received quality value or the third received quality value satisfies a handover triggering condition with reference to the cell-specific reference signal. A transmitter transmits trigger information to the neighboring cell in order to activate handover from a serving cell to the neighboring cell, based on the judgement results.
