Base station, wireless communication system, and wireless communication method

A wireless communication system in which a base station performs wireless communication with a terminal using a directional antenna within the predetermined area, the wireless communication system comprising:

• a database that holds data indicating an antenna directivity of the base station suitable for each state of the terminal or each arrival direction of a radio wave from the terminal measured in a scale model in which a structure within the predetermined area is reduced at a predetermined scale factor,
• wherein the base station includes:
• collection circuitry configured to collect a state of a terminal or an arrival direction of a radio wave from the terminal in practice within the predetermined area, and
• controller configured to control directivity of the directional antenna with respect to the terminal in practice within the predetermined area based on the state of the terminal or the arrival direction of the radio wave from the terminal collected by the collection circuitry, and data held by the database.

A wireless communication method in which a base station performs wireless communication with a terminal using a directional antenna within a predetermined area, the wireless communication method comprising:

• acquiring data from a database that holds the data indicating an antenna directivity of the base station suitable for each state of the terminal or each arrival direction of a radio wave from the terminal measured in a scale model in which a structure within the predetermined area is reduced at a predetermined scale factor;
• collecting a state of a terminal or an arrival direction of a radio wave from the terminal in practice within the predetermined area;
• and
• controlling directivity of the directional antenna with respect to the terminal in practice within the predetermined area based on the collected state of the terminal or the arrival direction of the radio wave from the terminal, and the acquired data.
