Abstract
The present invention is designed to allow a communication system employing massive-MIMO to optimize its performance. A mobile station apparatus transmits a synchronization signal by controlling the transmission direction of the transmitting beam for the synchronization signal by means of beamforming using a plurality of antenna elements, and has a synchronization signal processing section (62) that generates the synchronization signal including identification information of the mobile station apparatus, and changes the beamforming weight for the synchronization signal at predetermined time intervals, and a transmitting section (63) that transmits the synchronization signals generated in accordance with each beamforming weight on the uplink.
