Analysis and Optimization of Resource Control in High-Speed Railway Wireless Networks
TL;DR: A dynamic admission control and resource allocation algorithm is proposed, which is suitable for distributed implementation, and the performance of the proposed algorithm is evaluated by theoretical analysis and numerical simulations under realistic conditions of HSR wireless networks.
Delay-Aware Online Service Scheduling in High-Speed Railway Communication Systems
TL;DR: This work proposes a distributed online scheduling algorithm based on approximate MDP and stochastic learning, where the scheduling policy is a function of the local CSI and QSI only.
