Abstract:
A wireless communication device includes a receiver and a transmitter. The receiver receives a plurality of first frames each including first information for generation of a trigger frame for uplink multi-user transmission. The transmitter transmits a second frame generated on the basis of the first information included in the plurality of first frames, the second frame being the trigger frame and designating at least one target terminal for the uplink multi-user transmission. Each of the first frames is transmitted by a respective one of terminals, each of which accesses a wireless medium using an access category associated with the first frame under CSMA/CA (Carrier Sense Multiple Access with Carrier Avoidance) to transmit the first frame. The second frame instructs the at least one target terminal to transmit third frames including data in a SIFS (Short Interframe Space) after the second frame is received.
