Claim of US Patent No. 11,032,863

1. A wireless communication device comprising:a wireless communication circuit that performs a plurality of wireless communications by switching the wireless communications by performing time division multiplexing of channels used for the wireless communications; and
a processor that causes the wireless communication circuit to perform a first wireless communication for wirelessly communicating via a relay device which is different from the wireless communication device and a second wireless communication for wirelessly communicating with a wireless terminal through a Peer to Peer system,
wherein the wireless communication circuit performs the time division multiplexing of a first channel and a second channel, the first channel corresponds to the first wireless communication, and the second channel corresponds to the second wireless communication,
the wireless communication circuit obtains a communication amount of data of the first channel in a first frame and a communication amount of data of the second channel in the first frame, and determines a length of an allocation time period to be allocated to the second channel for a second frame that is different from the first frame based on the obtained communication amount of data of the first channel and the obtained communication amount of data of the second channel, and the first and second frames are not frames for WiMAX, and
the wireless communication circuit switches between the first channel and the second channel according to the determined allocation time period.
