Due to proliferation of portable smart devices (e.g., laptops, tablets, smart phones), mobile data traffic even in high-mobility environments has been explosively increasing. Hence, recently, high-speed train (HST) communications have particularly attracted a lot of attention. In order to provide emerging services (e.g., virtual reality (VR) / augmented reality (AR), video- conferencing, online gaming) in HSTs, the HST communications system is required to support not only higher data rate but also lower latency. However, recent studies are mostly focusing on increasing data rate while reducing latency is also indispensable, especially when the HST communications system is a time-division duplex (TDD) system. Therefore, this paper proposes a latency reducing method for TDD-based HST communications that involves a new TDD configuration and interference cancellation (IC) method. Simulation shows that the proposed scheme with IC is capable of efficiently reducing the latency without performance loss in data rate.
