Standardization activities of a satellite component for IMT-Advanced system

Abstract

In this paper, we introduce standardization activities for satellite component of IMT-Advanced systems which will play an important role, especially in providing multimedia broadcasting and multi-casting services due to its inherent characteristics. Recently, new satellite radio interfaces are being developed which have high commonality between terrestrial radio interfaces. This paper introduces the basic concept and architecture of the satellite IMT-Advanced system, and discusses the related standardization activities.
