Abstract
Wireless LAN (WLAN) developed quite fast over the last two decades, and the next generation WLAN standard: IEEE 802.11ax will be released in 2020. IEEE 802.11ax needs to improve the performance and user experience under the ultra-high-dense deployment of cells. Thus, the concept of spatial reuse (SR) is introduced in IEEE 802.11ax by enabling more communication links to simultaneously transmit. This paper proposes an environment sensing based link adaptation algorithm (ESBLA). ESBLA introduces intelligent environment sensing and identifies the environment into several types: nice environment, serious collision, and severe channel fading. After that, ESBLA adjust the media access control (MAC) layer transmission strategy according to the sensed environment type. The simulation results show that ESBLA can reduce the impact of intensive deployment interference as much as possible while guaranteeing high throughput.
