<p>A wireless LAN terminal (AP) transmits a data frame to an opposed wireless LAN terminal (STA-j) and receives an ACK frame therefrom. The AP determines a response time from the time when it transmitted the data frame till the time when it received the ACK frame. The AP also determines a transmission interval from a time when it previously transmitted a data frame to STA-j till the time when it transmitted the data frame thereto at this time. The AP has a memory in which a specified transmission interval and a specified response time are stored. When the transmission interval does not exceed the specified transmission interval but the response time exceeds the specified response time, the AP retransmits the data frame. When the transmission interval exceeds the specified transmission interval, the AP stores, into the memory, the response time as a specified response time (i.e., the AP updates the memory).</p> |
