Claim of US Patent No. 10,484,990

1. A wireless communication device, comprising:a transmitter configured to transmit a first frame that contains first
information specifying a plurality of frequency components and does not include second information specifying other wireless communication devices to which the plurality of frequency components are allocated;
a receiver configured to simultaneously receive second frames transmitted
by transmitting devices via frequency components randomly selected from among the plurality of frequency components specified in the first information, wherein the transmitting devices transmitting the second frames are ones of the other wireless communication devices and are different from each other; and
controlling circuitry configured to allocate first frequency components
selected from among the plurality of frequency components based on third information to the transmitting devices transmitting the second frames, wherein the first frequency components are different from each other,
wherein the receiver is further configured to receive the third information
through the second frames or third frames transmitted before the second frames are transmitted, and
wherein the third information contains communication quality information
on a second frequency component selected from among the plurality of frequency components, and communication quality information on an entire frequency band to which the plurality of frequency components belong.
