This paper addresses key features of the satellite component of IMT‐Advanced systems, including candidate system architectures, service scenarios, and candidate radio interfaces. We consider integrated/hybrid satellite and terrestrial networks as an efficient means to meet the main service requirements of the satellite component. As satellite bandwidth is a very scarce resource, efficient frequency reuse techniques will play an important role in the successful deployment of the service. For this reason, we propose an efficient frequency reuse technique, designed for an integrated satellite system to support IMT‐Advanced services. In the proposed scheme, satellite and terrestrial components effectively share the same bandwidth. Copyright © 2010 John Wiley & Sons, Ltd.
