Abstract:

This proposal will be discussing the fundamental theory of statistical queuing and delay analysis, which controls the delay-bound violation probability within a very low tolerable level. This theory and its application typically aim at preventing delay violation from frequently happening. In other words, it is an approach for small or tail probability control, which has wide application in wireless communications and networking, especially on delay–bounded quality of service (QoS) assurance. This proposal would start with the background introduction on how statistical delay-bounded QoS metrics are important in current and future wireless networks. Then, the fundamental theory will be elaborated on in details with vivid illustration. Applications of the theory on delay-bounded QoS provisioning include how it is applied in diverse wireless networking scenarios, including point-to-point links, point-to-multi-point networks, relay networks, full-duplex enabled networks, device-to-device (D2D) underlaid networks, cognitive radio (CR) networks, etc. Moreover, we would also like to share our latest research progress regarding how to apply the theories’ into a wide spectrum of interests in wireless communications, including battery management, social-aware D2D networking, energy harvesting networks, orbital-angular-momentum (OAM) based multi-mode networks, as well as security assurance.

Abstract:

To address the ever-increasing wireless traffic demands and challenges on the high dense network scenarios, in recent years, academia and industry are working on the key technology and standardization process of the next generation wireless local area network (WLAN) standard: IEEE 802.11ax. Different from previous versions of the 802.11 mainly focusing on the increase of the maximum transmission rate, IEEE 802.11ax is more concerned about the performance improvements of high dense network scenarios, such as per user average throughput, area throughput etc. This tutorial focuses on the latest IEEE 802.11ax standards. First of all, we comprehensively and deeply analyze the background, requirements and objectives of the 802.11ax. Furthermore, the key technologies such as physical layer enhancements, multi-user MAC, spatial reuse, energy saving, and etc. are discussed in detail. Next, the performance of 802.11ax is evaluated through the integrated link level and system level simulation platform. Finally, we show our insights on 802.11ax and perspectives of 802.11ax beyond.
