Abstract:
The present invention is designed to reduce the time it takes to form adequate beams, in communication using beamforming. According to one aspect of the present invention, a user terminal has a transmission section that, using temporally orthogonal radio resources, forms different transmitting beams and transmits reference signals respectively to a radio base station, and a control section that controls the forming of the transmitting beams so that at least one of the reference signals is received in a receiving beam which the radio base station forms in a given period set.
