Claim of US Patent No. 10,368,358

1. A wireless communication device comprising:a receiver configured to receive a first type of frame including information to specify a plurality of frequency components;
controlling circuitry configured to determine whether a transmission right to respond to the first type of frame is acquired based on a first value selected from a first value range and a number of the frequency components specified in the first type of frame; and
a transmitter configured to transmit, in a case of the transmission right to respond to the first type of frame being acquired, a second type of frame using a frequency component selected from the plurality of frequency components, wherein
the receiver is configured to receive a third type of frame including at least one of a first update value and a second update value for the first value range, the first update value and the second update value depend on a number of wireless communication terminals which have successfully transmitted the second type of frames, the first update value is for a wireless communication terminal in which the transmission of the second type of frame has failed, the second update value is for a wireless communication terminal in which the transmission of the second type of frame has succeeded, and the third type of frame is transmitted upon reception of the second type of frame, and
the controlling circuitry is configured to update the first value range based on the first update value in a case of determining that the transmission of the second type of frame has failed and based on the second update value in a case of determining that the transmission of the second type of frame has succeeded.
