Abstract
A wireless communication system includes a control station and a plurality of second wireless communication apparatuses. The control station includes a management table that holds sending permission information indicating whether or not to transmit a packet for requesting to send an orientation estimation auxiliary signal. The plurality of second wireless communication apparatuses each refer to the management table, transmit the packet to a first wireless communication apparatus in response to the sending permission information, and perform orientation estimation using the orientation estimation auxiliary signal transmitted from the first wireless communication apparatus.
