With the fast development of high-speed railway (HSR), the demand for mobile communication on high-speed trains is increasingly growing. This leads to significant attention on the study of resource management in HSR wireless communications with limited bandwidth. Resource management is a challenging problem due to heterogenous quality of service (QoS) requirements and dynamic characteristics of HSR wireless communications. In this article, we first provide a state-of-the-art overview on HSR wireless communications and the existing resource management schemes. Then a location-aware cross-layer optimization framework is developed for the dynamic resource management with realistic system model, where the train location information is exploited to facilitate dynamic design. Next we demonstrate the applications of stochastic network optimization theory in solving the dynamic resource management problem in HSR wireless communications. Finally, we highlight some future research directions for location-aware dynamic resource management in the conclusion.
