Information processing device, information processing system, terminal device, and information processing method

An information processing system, comprising:

• a terminal device including an antenna device that includes a plurality of antenna elements;
• and
• an information processing device, which generates control information for controlling directivity of a radio signal by the antenna device,
• wherein the information processing device acquires
• first information according to a measurement result of a phase of a radio signal transmitted from a first antenna element among the plurality of antenna elements, and
• second information according to a measurement result of a relative deviation between the phase of the radio signal transmitted from the first antenna element and a phase of a radio signal transmitted from a second antenna element different from the first antenna element, and
• generates the control information based on the first information and the second information.

A terminal device, comprising:

• an antenna device including a plurality of antenna elements, and
• a control unit that controls directivity of a radio signal transmitted from the antenna device based on control information generated in advance,
• wherein the control information is generated based on
• first information according to a measurement result of a phase of a radio signal transmitted from a first antenna element among the plurality of antenna elements, and
• second information according to a measurement result of a relative deviation between the phase of the radio signal transmitted from the first antenna element and a phase of a radio signal transmitted from a second antenna element different from the first antenna element.

An information processing method, by a computer, comprising:

• acquiring
• first information according to a measurement result of a phase of a radio signal transmitted from a first antenna element among a plurality of antenna elements included in an antenna device, and
• second information according to a measurement result of a relative deviation between the phase of the radio signal transmitted from the first antenna element and a phase of a radio signal transmitted from a second antenna element different from the first antenna element;
• and
• generating control information for controlling directivity of a radio signal transmitted from the antenna device based on the first information and the second information.
