Wireless communication device and wireless communication method
First Claim
1. A wireless communication device comprising:
- a communicator configured to communicate through a first frequency channel of first frequency channels;
a transmitter configured to transmit a signal of wireless power transfer to a first wireless communication device through a second frequency channel; and
controlling circuitry configured to estimate a first state of at least one of the first frequency channels, whereinthe controlling circuitry is configured to estimate a second state of the second frequency channel based on the first state of at least one of the first frequency channels and control a directivity of the signal on the basis of the second state of the second frequency channel.

Abstract
According to one embodiment, a wireless communication device includes a communicator, a transmitter and controlling circuitry. The communicator is communicable using a plurality of first frequency channels. The transmitter transmits a signal using a second frequency channel having a bandwidth larger than that of each of the plurality of first frequency channels. The controlling circuitry selects the first frequency channel, of the plurality of first frequency channels, belonging to a band of the second frequency channel and uses the selected first frequency channel to perform channel estimation to acquire first channel information representing a state of the selected first frequency channel. The controlling circuitry calculates second channel information representing a state of the second frequency channel on a basis of the first channel information and control a directivity of the signal on the basis of the second channel information.
