Abstract

There is provided a wireless communication device includes a transmitter configured to transmit a known signal in each of a plurality of first directions different from each other, a receiver configured to receive a plurality of first reflected waves, each of the plurality of first reflected waves being generated by the known signal transmitted in each of the plurality of first directions and to detect each of a plurality of first reception intensities, each of the plurality of first reception intensities being associated with each of the plurality of first reflected waves; and a controller configured to determine a transmission direction of a radio signal addressed to a first wireless terminal, based on the plurality of first reception intensities and to control the transmitter to transmit the radio signal in the transmission direction.

First claim

What is claimed is:

1. A wireless communication device comprising:
a transmitter configured to transmit a known signal in each of a plurality of first directions different from each other;
a receiver configured to receive a plurality of first reflected waves, each of the plurality of first reflected waves being generated by the known signal transmitted in each of the plurality of first directions and to detect each of a plurality of first reception intensities, each of the plura…
