摘要
随着移动通信技术的飞速发展,LTE技术作为移动通信系统的主要演进方向,以其高速率、低时延的特点,越来越受到世界各大主流运营商和设备厂商的广泛关注。由于OFDM和MI-MO等先进技术的引入,使LTE系统的资源分配具有很大的灵活性,但是,面对这样灵活的系统,如何高效地利用这些时频资源,有效提高LTE系统的频谱效率,还有很多问题有待研究和解决。
With the development of mobile communication technology,the LTE technology as the main direction of evolution,with its high-speed,low latency characteristics,aroused more and more concern of major operators and equipment vendors in the world.As the introducing of the advanced technologies such OFDM and MIMO,LTE system has great flexibility in resource allocation,however,to such a flexible system,how to efficiently use these time-frequency resources to improve the spectral efficiency of LTE system,there are many issues to be researched and resolved.
