A virtual base station apparatus (virtual AP) formed by a plurality of base station apparatuses (APs) requests a terminal apparatus (STA) to start beamforming training. The terminal apparatus transmits a plurality of first training frames to the virtual base station apparatus. The virtual base station apparatus receives the plurality of first training frames by using the plurality of base station apparatuses, and transmits a plurality of second training frames including information on a training frame received under the best conditions from a first base station apparatus that has received the training frame received under the best conditions to the terminal apparatus. The terminal apparatus receives the plurality of second training frames, and transmits to the virtual base station apparatus a second frame including information on a frame received under the best conditions among the plurality of second received training frames.
