摘　　要：作为一项LTE上行链路增强方案,3GPP R12版本启用了上行64QAM技术。相比于上行16QAM技术,上行64QAM技术理论上能够使LTE上行速率提高50%。针对上行64QAM技术,首先从上行64QAM基本原理、网络及终端能力指示、上行64QAM开启条件等方面进行了相关研究。随后对上行64QAM技术在LTE网络中的定点速率、移动性能和覆盖性能做了详细的分析。最后给出了相关研究和分析结论。As an LTE uplink enhanced scheme,3 GPP release 12 enables uplink 64 QAM technology. Compared with uplink 16 QAM technology,uplink 64 QAM technology can increase the uplink rate of LTE by 50% theoretically. In view of uplink 64 QAM technology,it first studies the basic principles of uplink 64 QAM,the indication of network and terminal capability,and the threshold of uplink 64 QAM. Then it analyzes uplink rate,mobile and coverage performance of uplink 64 QAM in LTE in detail. At last,it gives the related research and analysis conclusions.
