High-speed railway (HSR) communications have recently attracted much attention due to some specific railway needs, such as passenger experience services, business process support services, and operational data and voice services. The HSR radio channel, as a basis for the design of HSR communication systems and the evaluation of HSR communication technologies, has not yet been sufficiently investigated...
A dynamic resource allocation algorithm is investigated for the orthogonal frequency division multiplexing access (OFMDA) system under the network architecture of High-Speed Railway (HSR). The mobile base station (MBS) on the top of the train forwards the signal received from the base station (BS) on the ground to the user equipments (UE) in the train. Due to the high mobility in the BS-MBS link,...
This paper seeks to explore the integration of spectrum and network resource management functionalities for the benefit of achieving higher performance and capacity gains in an International Mobile Telecommunications-Advanced (EVIT-A) scenario. Supporting wider bandwidth up to 100MHz is one of the key features for EVIT-Advanced systems. Spectrum aggregation (SA) has been studied as a major solution...
