Outline of Final Research Achievements

During the three year study, we designed an efficient implementation of the 802.11ax Wireless LAN MAC. Specifically, our design focused on the UL OFDMA random access which is a new feature introduced in 802.11ax. This feature improves the users' Wireless LAN experience in very user dense environments by allowing them to transmit at the same time even without prior channel reservation. We presented our results for maximizing the efficiency of this feature both in domestic and international conferences and contributed to the 802.11ax international standardization. One of our contribution done jointly with researchers in the industry was subsequently accepted by the IEEE task group ax to be included in the next generation standard. As a future research direction, carrier sensing combined with UL OFDMA can be used to further improve efficiency through collision avoidance.
