Satellite and terrestrial integrated mobile communication systems (STICS) is proposed to construct economical and highly-reliable communication networks. One of the promising approaches to share the frequency spectrum in STICS is dynamic spectrum assignment, which dynamically divides the spectrum into two parts according to the traffic demand of terrestrial service and satellite service. As smaller bandwidth can be allocated to satellite networks, it is required to increase the bandwidth per cell by decreasing the frequency reuse factor, which results in larger inter-cell interference. This is much worse for users at the edge of the satellite cell as the coverage of satellite beam is much flatter than that of terrestrial cell. To solve this problem, this paper proposes a scheme of dynamic channel assignment scheme with cooperative beam forming, in which adjacent beams will serve the edge users cooperatively. Simulation results show that this scheme can improve the SINR of edge users significantly. |
