WIPO Patent Application WO/2021/084592

A1

This information processing device comprises: an acquisition unit that uses a first polarized wave and a second polarized wave inclined at a prescribed angle in relation to the first polarized wave, and acquires measurement information for a plurality of antenna elements included in an antenna device that transmits wireless signals; and a generation unit that generates control information for controlling the directionality of the wireless signals on the basis of the measurement information. The measurement information contains: first information based on the measurement result of the first polarized wave transmitted from a first antenna element, among the plurality of antenna elements; second information indicating the relative difference between the first polarized wave transmitted from the first antenna element and the second polarized wave transmitted from the first antenna element; and third information indicating the relative difference between a wireless signal transmitted from the first antenna element and a wireless signal transmitted from a second antenna element differing from the first antenna element.
