摘要:

为了进一步提高HSPA系统的峰值数据速率以及用户吞吐量,3GPPRel-7中引入了MIMO技术。MIMO技术能在不增加带宽的情况下提高频谱效率,提高数据速率。为了满足宽带移动通信业务的需求,3GPPRel-9及后续版本中又引入了MIMO结合多载波的HSDPA技术。本文首先阐述了HSPA+ MIMO技术的演进方向,然后介绍了HSPA+ MIMO的技术原理,最后分析了MIMO对非MIMO终端的影响。

In order to further improve the peak data rate and user throughput of HSPA network, MIMO technology is introduced in 3GPP Rel-7. MIMO technology can increase spectral efficiency and data rates without using additional bandwidth. For affordability of mobile broadband services, MIMO is applied to multi-carrier HSDPA in 3GPP Rel-9 and beyond release. Firstly the perspective of future evolution of MIMO technology is presented in this paper, it introduces the principles of HSPA+ MIMO, and finally the effects of non-MIMO UEs in HSPA+ MIMO network are analyzed.
