Bargaining-Based Spectrum Allocation Algorithm for High-Speed Railway Communications

The explosive growth of data traffic in the high-speed railway (HSR) communications has attracted much research attention to boost technical innovations and developments for next generation mobile communication networks. However, traditional terrestrial network is difficult support various HSR service requirements while ensuring seamless coverage ultra-wide regions. In this study, we develop a new spectrum allocation scheme communications. By leveraging satellite communications, our proposed implemented on integrated terrestrial-satellite (ITSN) platform. Based weighted proportional gain loss bargaining solutions, approach can adaptively share limited ITSN resource with its tight interaction complementary characteristics To take full advantages collaborative control process, coordinated paradigm explores mutual benefits achieve reciprocal consensus under dynamically changing obtained solution globally desirable features provide guidelines operation. Finally, numerical results demonstrate strengths by using extensive simulations, highlight open issues future directions.
