卫星移动通信系统作为地面移动通信系统的补充，可以填补地面网络无法覆盖的空白，为灾害应急通信提供了不可替代的解决方案。为了为未来的卫星/地面综合通信网络铺平道路，ITU-R邀请了国际移动通信(IMT)-高级卫星组件的候选无线电接口技术（RIT）提案。中国提出了长期演进（LTE）卫星RIT作为IMT-Advanced卫星技术的备选方案。提交的lte卫星候选RIT是基于3GPP开发的地面LTE-Advanced FDD标准指定的。考虑到卫星需求，对LTE-Advanced进行了一些修改，以适应卫星无线电传输环境。本文简要介绍了lte卫星的新特性。
As a complementary to terrestrial mobile communication systems, mobile satellite communication system can fill the gaps that cannot be covered by terrestrial network, and provides an irreplaceable solution for emergency communication in disaster. To pave the road for future satellite/terrestrial integrated communication networks, ITU-R invited proposals for candidate Radio Interface Technology (RIT) for the satellite component of International Mobile Telecommunications (IMT)-Advanced. China proposed the RIT of Long Term Evolution (LTE)-satellite as a candidate to be considered as IMT-Advanced satellite technology. The submitted LTE-satellite candidate RIT is specified based on terrestrial LTE-Advanced FDD standards that are developed in 3GPP. Considering satellite requirements, a number of modifications to LTE-Advanced are made to adapt to satellite radio transmission environments. This paper provides a general introduction of the new characteristics of LTE-satellite.
