Abstract
There is provided a wireless communication device that may prevent a degradation of QoS of communications caused by a schedule change. A wireless communication device in a wireless communication system that transits and receives a traffic stream using a millimeter wave includes a schedule generator, a transmitter, and a receiver, the schedule generator generating a schedule for at least one wireless station, which communicates with the wireless communication device, to transmit a plurality of traffic streams, the transmitter transmitting the generated schedule to the wireless station using a broadcast frame, the receiver receiving QoS requests transmitted by the respective wireless stations, each of the QoS requests including a current MCS index and a range of available MCS indexes for transmitting a traffic stream. In accordance with the QoS requests received by the receiver the schedule generator sets a period for periodically allocating respective transmission time periods of the plurality of traffic streams, and generates a schedule in which, in each period, an interval is provided between transmission time periods of the plurality of traffic streams, the transmission time peri…
