Abstract
According to one embodiment, a wireless communication device includes a transmitter configured to transmit a first frame including information to specify a plurality of frequency components; and controlling circuitry configured to determine whether a second frame is received via each of the plurality of frequency components. The transmitter is configured to transmit a third frame including first information concerning a first value range which is used to determine whether to respond to the first frame, the first value range being dependent on a number of frequency components via which the second frame has been received.
Claims9
A wireless communication device comprising:
- a receiver configured to receive a first type of frame including a receiving address field, at least one first field to specify a plurality of frequency components and one or more second fields wherein a broadcast address is contained in the receiving address field, and an AID (Association ID) designating a terminal or a value not designating any terminal is contained in each of the one or more second fields, at least one of the one or more second fields contains the value not designating any terminal;
- controlling circuitry configured to determine frequency components for which any terminal is not designated based on the at least one first field and the at least one second field containing the value not designating any terminal in response to that the AID value designating the wireless communication device is not contained in any of the second fields, and determine whether to respond to the first type of frame, based on a first value selected randomly from a first value range and a number of the determined frequency components;
- and
- a transmitter configured to, in response to determining to respond to the first type of frame, select one frequency component from the determined frequency components and transmit a second type of frame using the selected frequency component, wherein
- the controlling circuitry is configured to determine whether transmission of the second type of frame has succeeded or failed, and adjust the first value range based on a result of determining whether transmission of the second type of frame has succeeded or failed.
A wireless communication method performed by a wireless communication device comprising:
- receiving a first type of frame including a receiving address field, at least one first field to specify a plurality of frequency components and one or more second fields wherein a broadcast address is contained in the receiving address field, and an AID (Association ID) designating a terminal or a value not designating any terminal is contained in each of the one or more second fields, at least one of the one or more second fields contains the value not designating any terminal;
- determining frequency components for which any terminal is not designated based on the at least one first field and the at least one second field containing the value not designating any terminal in response to that the AID value designating the wireless communication device is not contained in any of the second fields, and determining whether to respond to the first type of frame, based on a first value selected randomly from a first value range and a number of the determined frequency components;
- selecting to, in response to determining to respond to the first type of frame, one frequency component from the determined frequency components and transmitting a second type of frame using the selected frequency component;
- and
- determining whether transmission of the second type of frame has succeeded or failed, and adjusting the first value range based on a result of determining whether transmission of the second type of frame has succeeded or failed.
