Abstract
To improve system performance for mobile communications (group mobility) in a plurality of terminals existing inside the same moving object, a radio base station, which forms a cell on a moving path of a moving object to communicate with a mobile station provided in the moving object using beam forming, is provided with a transmission section that transmits a plurality of acquisition signals applied with different beam forming weights respectively to at least an edge region of the cell formed on the moving path of the moving object, and a control section that controls a beam forming weight to apply to a data signal transmitted to the mobile station, based on information notified from the mobile station receiving an acquisition signal.
