Query: Delay-Aware Dynamic Resource Management for High-Speed Railway Wireless
  Communications   In this paper, we investigate the delay-aware dynamic resource management
problem for multi-service transmission in high-speed railway wireless
communications, with a focus on resource allocation among the services and
power control along the time. By taking account of average delay requirements
and power constraints, the considered problem is formulated into a stochastic
optimization problem, rather than pursuing the traditional convex optimization
means. Inspired by Lyapunov optimization theory, the intractable stochastic
optimization problem is transformed into a tractable deterministic optimization
problem, which is a mixed-integer resource management problem. By exploiting
the specific problem structure, the mixed-integer resource management problem
is equivalently transformed into a single variable problem, which can be
effectively solved by the golden section search method with guaranteed global
optimality. Finally, we propose a dynamic resource management algorithm to
solve the original stochastic optimization problem. Simulation results show the
advantage of the proposed dynamic algorithm and reveal that there exists a
fundamental tradeoff between delay requirements and power consumption.
