Resource Allocation in Vehicular Communications
By: Prof. Geoffrey Ye Li
Georgia Institute of Technology, USA
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.
