Abstract
According to one embodiment, a wireless communication device includes: a receiver that configured to receives a first frame; and a transmitter that configured to transmits a second frame including a first identifier and acknowledgement information on the first frame, the first identifier being extracted from a predetermined field of the first frame and being different from a source address of the first frame.
Claims9
A wireless communication device comprising:
- a controller configured to read first information on correspondence between MAC (Media Access Control) addresses and AIDs (Association Identifiers) for one or more target terminals from a first hardware storage including second information on correspondence between MAC addresses and AIDs for a plurality of terminals, the first information being part of the second information, and store the first information in a second hardware storage,
- a transmitter configured to transmit a first frame containing information for specifying resource units allocated to the one or more target terminals;
- a receiver configured to receive one or more second frames transmitted in response to the first frame via one of the resource units in Uplink OFDMA (Orthogonal Frequency Division Multiple Access) from at least one of the one or more target terminals, the one or more second frames including MAC addresses of the at least one of the one or more target terminals which have transmitted the one or more second frames;
- wherein
- the controller is configured to specify the received MAC addresses included in the one or more second frames, access the second hardware storage to read the first information and obtain AIDs corresponding to the specified MAC addresses which are AIDs of the at least one of the one or more target terminals, and
- the transmitter is configured to transmit a third frame including sets of
- the AIDs of the at least one of the one or more target terminals and
- acknowledgement information indicating success or failure of reception of the one or more seconds from the at least one of the one or more target terminals.
