| Abstract(in English) | For next generation wireless LAN system (IEEE802.11ax), the increase of clear channel assessment (Carrier Sense) level (or carrier sense level) has been studied to improve the user throughput. Since the capable STA (ax STA) that increases carrier sense level can obtain the high transmission opportunity (TXOP), its user throughout can be improved. On the other hand, in the co-existing environment where there are the ax STA and non-capable STA (Legacy STA) that doesn’t increase carrier sense level, the legacy STA reduces its user throughput due to the interference signal arising from the ax STA having high TXOP. For the ax/legacy STA co-existing environment, this paper proposes the transmit power control (TPC) scheme for the ax STA, which maintains the user throughput of both legacy STA and ax STA. And, by system level simulation assuming the wireless LAN system, we show the system level performance of proposed scheme. |
