Nikolay Korolev – Analytical Model of Multi-link Operation in Heterogeneous Wi-Fi 7 Networks

Описание: The upcoming IEEE 802.11be standard, known as Wi-Fi 7, introduces the multi-link operation, which allows a Wi-Fi device to transmit and receive packets via several links simultaneously. However, in some cases, for example, when the spectral distance between two channels used by the links is small, cross-link interference caused by the transmission on one link can impair the transmission on another link. 802.11be defines operation rules for this case called the non-simultaneous transmit and receive (NSTR) mode. Particularly, the specification requires simultaneous transmissions on different links to be aligned. Otherwise, the transmission shall be performed on only one link. In this seminar the participants will uncover an the analytical model of the NSTR operation, and witness its predictions of throughput in a saturated network when NSTR multi-link devices coexist with legacy devices.

Bio: Nikolay Korolev received the B.S. and M.S. degree in applied mathematics and physics from the Moscow Institute of Physics and Technology, in 2016 and 2018, respectively. He is currently a PhD student under the supervision of Evgeny Khorov at the Moscow Institute of Physics and Technology. He is also a researcher at Huawei Moscow Research Center. His research interests are related to wireless communication systems, next-generation Wi-Fi, QoS-aware optimization, theoretical computer science, and computational complexity.
