Wireless communication apparatus, wireless communication system, and beam search signal transmission method

A wireless communication system comprising:

• a first wireless communication apparatus configured to include a first memory and a first processor coupled to the first memory and the first processor configured to:
• determine a number of transmissions of beam search signal for performing a beam search in an area where the beam search is performed, and determine a combination of the area and a presence/absence of the beam search signal according to the determined number of transmissions of beam search signal, based on a number of areas where the beam search is performed and a number of beams formed in the area by a transmission time of the beam search signal by the wireless communication apparatus, and
• generate the beam search signal to be transmitted to another wireless communication apparatus according to the determined combination;
• and
• a second wireless communication apparatus configured to include a second memory and a second processor coupled to the second memory and the second processor configured to:
• obtain the beam search signal generated by the first wireless communication apparatus,
• perform the beam search based on the beam search signal obtained.
