Abstract

In order to improve the network performance in the high dense multi-BSSs, the next generation WLAN: IEEE 802.11ax introduces spatial reuse (SR) technology to improve the spectrum utilization, manage the multi-BSSs interferences and increase the possibility of simultaneous transmissions. This paper firstly introduces the SR technologies of IEEE 802.11ax in detail. After that, to fully verify the performance, we build a system & link level integrated simulation platform for IEEE 802.11ax and achieve the SR. Finally, we evaluate the performance of the SR through the built simulation platform, the simulation results clearly indicate that the network throughput is improved by 34.3 in uplink scenarios. To the best of our knowledge, this is the first work to introduce and evaluate the SR technologies for IEEE 802.11ax.
