The STAstransmit, to the AP, a second signal in which a delay time is set, the delay time being calculated from a difference between the transmission start time acquired from the first signal and a reception start time of the first signal at the own station. The APacquires delay time from the second signal of each STA, decides a timing for permitting transmission by each of the STAsby time division, on the basis of the acquired delay time, and notifies the STAsthereof. The STAseach effect control to start transmission of signals to the APat the timing notified from the AP
