IEEE Distinguished Lecture Tour by Prof. Geoffrey Li

On behalf of the IEEE joint VT/COM/IT Sweden Chapter Board, We are delighted to invite you to an IEEE Vehicular Technology Society Distinguished Lecture Tour (DLT) by Prof. Geoffrey Li, Georgia Institute of Technology, Atlanta, Georgia, USA.

Seminar#1 – Lund University, Lund, Sweden
Title: Device-to-Device Communications in Cellular Networks
Date and time: Mar 14, 2018, 15:15-16:30.
Location: Room E:1406, ground floor, E-building, John Ericssons väg 4, Lund University, Lund, Sweden
Local host: Michael Lentmaier, michael.lentmaier@lth.se.

To satisfy the increasing demand of high data-rate services, provide better user experience, and alleviate the huge infrastructure investment of operators, device-to-device (D2D) communications have being considered as one of the key techniques in the 5G wireless networks. With D2D communications, proximity users in a cellular network can communicate directly to each other without going through the base station (BS). It can potentially increase spectral-efficiency (SE) and device energy-efficiency (EE) of communications. However, D2D communications may generate interference to the existing cellular network if not designed properly. Therefore, interference management is one of the most challenging and important issues in D2D communications. This talk will focus on interference management in D2D communications including quality-of-service (QoS) aware admission control and SE/EE based mode selection. Cross-layer optimization and concave-convex procedures (CCCP) are exploited to solve the related optimization problems.

Seminar#2 – Chalmers, Gothenburg, Sweden
Title: Resource Allocation in Vehicular Communications
Date and time: Mar 16, 2018, 13:00-14:30.
Location: Room EE, floor 6, EDIT building, Hörsalsvägen 11, Campus Johanneberg, Chalmers University of Technology, Gothenburg, Sweden.
Local host: Tommy Svensson, tommy.svensson@chalmers.se

Seminar#3 – Linköping University, Linköping, Sweden
Title: Resource Allocation in Vehicular Communications
Date and time: Mar 19, 2018, 10:15-11:30.
Location: Room Systemet, floor 2, entrance 27, B building, Campus Valla, Linköping University, Linköping, Sweden.
Local host: Danyo Danev, danyo.danev@liu.se.

This talk will address resource allocation in vehicular communications. Different from traditional resource allocation, strong dynamics caused by high mobility in the vehicular environments poses a serious obstacle to the acquisition of high-quality channel state information (CSI). To deal with the issue, we investigate the delay impacts of periodic CSI feedback and develop efficient graph-based centralized resource management schemes to meet the diverse quality-of-service (QoS) requirements in vehicular networks. To further reduce signaling overhead, we take advantage of recent advances in reinforcement learning (RL) and develop an effective distributed resource allocation scheme. We will show that the demanding latency and reliability requirements of vehicular communications, which are hard to model and analyze using traditional methods, can be explicitly accounted for in the proposed deep RL framework.
