Wireless communications device, wireless communications method, and wireless communications control program

A wireless communication apparatus which communicates with at least one wireless station apparatus by utilizing EDCA mechanism includes the following elements. A first channel state determining unit determines a usage state of a communication channel used between the wireless communication apparatus and the wireless station apparatus in a contention period of the communication channel. A first terminal occupation time calculating unit calculates, on the basis of the usage state, a different-terminal occupation time in the contention period of the communication channel. A first traffic measuring unit measures an amount of data received from the wireless station apparatus in the different-terminal occupation time. A first parameter adjusting unit adjusts an EDCA parameter set used in the EDCA mechanism, on the basis of the different-terminal occupation time and the amount of received data. A parameter updating unit updates the EDCA parameter set to an adjusted EDCA parameter set.
