Abstract
A predetermined STA includes a station information collection unit collecting from the STA itself and other STAs station information used for selection of STAs performing simultaneous transmission and for control of the simultaneous transmission, and a simultaneous-transmission request unit knowing occurrence of a QoS data frame based on the station information and transmitting a request frame requesting the simultaneous transmission to an AP. The AP includes a station information collection unit; a simultaneous-transmission determination unit selecting a combination of the STAs performing the simultaneous transmission based on the station information by reception of the request frame; and a trigger transmission unit transmitting to each of the STAs performing the simultaneous transmission a trigger frame instructing to performs the simultaneous transmission and including information necessary for controlling the simultaneous transmission. Each of the STAs designated by the trigger frame is configured to simultaneously transmit the wireless frames to the AP.
