Research of spectrum sharing network based on radio environment map

The current mode of spectrum allocation has limited the efficiency of spectrum utilization, which also restricts the innovations on radio technologies. Spectrum sharing has been recognized as one of the technical schemes to solve spectrum scarcity and improve spectrum efficiency. On the basis of literature reviews of spectrum sharing developments in European and American countries, the authors propose an intelligent spectrum sharing network architecture based on radio environment map and user classification. With complete and accurate spectrum information, the proposed network architecture makes different users share spectrum resources efficiently and dynamically through user classification access. Firstly, the components and functions of network elements in this architecture are emphatically introduced. Moreover, the procedure of information interaction among different network elements is discussed in detail. Finally, as a reference for spectrum sharing development in China, the key technologies to realize this architecture are also deeply analyzed.
