Abstract	The integrated and/or hybrid satellite and terrestrial network has become more and more important because of its broad application prospect and has received considerable attention. At the same time, the integrated network also brings many challenges, especially the problem of interference. Due to the lack of frequency spectrum, frequency reuse is considered in the satellite network and the terrestrial network for enhancing spectral efficiency. However, this will cause considerable Co-Channel Interference (CCI) and thus interference coordination is imperative. In this paper, we propose an interference coordination scheme for the integrated satellite and terrestrial network. The satellite sends pilots for channel estimation at terrestrial base-stations, and transmits the received data to the terrestrial gateway. Then interference coordination is performed at the terrestrial gateway, where the interference channel is updated according to both the estimated information and the predicted change based on the positions. Furthermore, based on the scheme, we analyze the precision that needs to be reached and obtain a direct view on how the precision may influence the system performance.
