摘要
LTE技术不仅使3GPP标准保持相对其他移动通信标准的竞争优势,同时也为3GPP标准向IMT-Advanced阶段演进打下了坚实的基础。本文探讨了LTE无线链路中的核心技术,包括上下行多址技术、多天线技术、导频技术、HARQ技术以及无线资源调度技术。最后,展望了LTE-Advanced系统的研究热点和演进方向。
LTE technologies not only make 3GPP outperform other mobile communication standards, but also provide a good evolution scheme for 3GPP to the IMT-Advaneed system. In the paper, the key technologies in LTE radio links are introduced, which include the uplink and downlink multiple access technology, multi-antennas technology, reference signal technology, HARQ technology and resource scheduling technology. In addition, the interested issues and technologies in LTE-Advanced systems are shown at the end of the paper.
