报告题目：Virtual Spectrum Hole: Exploiting User Behavior-Aware Time-Frequency Resource Conversion
报告摘要：In this talk, to address network congestion stemmed from traffic generated by advanced user equipment, we introduce a novel network resource allocation strategy, i.e., time-frequency resource conversion (TFRC), via exploiting user behavior, a specific kind of context information. The key idea is to use radio resources mainly on the traffic/connection to which a user pays attention. The TFRC withdraws spectrum resources strategically from connection(s) not focused on by the user, providing reuseable spectrum called “virtual spectrum hole”. Considering an LTE-type cellular network, a double-threshold guard channel policy is proposed to facilitate the implementation of TFRC. An analytical model is established to study benefits of exploiting TFRC in terms of call-level performance, including new call blocking, handoff call dropping, and recovering call dropping probabilities. Numerical results will be shown to demonstrate the effectiveness of the proposed approach, in increasing the cell capacity (maximum user number per cell) while limiting potential service quality degradation introduced by the newly proposed technique.
Hangguan Shan received the B.Sc. degree in electrical engineering from Zhejiang University, Hangzhou, China, in 2004, and the Ph.D. degree in electrical engineering from Fudan University, Shanghai, China, in 2009. From 2009 to 2010, he was a Post-Doctoral Research Fellow with the University of Waterloo, Waterloo, ON, Canada. Since 2011, he has been with the College of Information Science and Electronic Engineering, Zhejiang University, where he is currently an Associate Professor. His current research focuses on cross-layer protocol design, resource allocation, and the quality-of-service provisioning in wireless networks.
