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