WIRELESS COMMUNICATION APPARATUS, WIRELESS STATION APPARATUS AND WIRELESS COMMUNICATION METHOD

摘要

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.

1. A wireless communication apparatus which communicates with at least one wireless station apparatus by utilizing enhanced distributed channel access (EDCA) mechanism, comprising:
a first channel state determining unit that determines a usage state of a communication channel which is used between the wireless communication apparatus and the wireless station apparatus in a contention period of the communication channel, in a situation where the wireless communication apparatus communicates with one wireless station apparatus; a first terminal occupation time calculating unit that 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 that measures an amount of data received from the wireless station apparatus in the different-terminal occupation time; a first parameter adjusting unit that adjusts an EDCA parameter set used in the EDCA mechanism, on the basis of the different-terminal occupation time and the amount of data received from the wireless station apparatus; and a parameter updating unit that updates the EDCA parameter set to an adjusted EDCA parameter set.
