3GPP LTE-Advanced和珍贵资产的增强：动态TDD传输
Enhancements of the 3GPP LTE-Advanced and the Prized Asset: Dynamic TDD Transmissions
摘要：
在本文中，我们进行了新的第三代合作伙伴计划（3GPP）长期演进高级（LTE-Advanced）增强的调查，涵盖了最近通过的3GPP在LTE版本11和正在讨论的LTE版本12的技术。更详细地，我们介绍了载波聚合（CA），多输入多输出（MIMO）和协作多点（CoMP）以及三维（3D）MIMO的最新增强。此外，考虑到网络节点在未来将变得非常多样化，并且因此异构网络（HetNet）是LTE-Advanced网络的关键特征，我们还讨论了HetNet场景中感兴趣的技术，例如，增强的物理数据控制信道（ePDCCH）、进一步增强的小区间干扰协调（FeICIC）和小型小区，以及能量效率问题。特别是，我们特别关注LTE版本12中最重要的增强之一，即，动态时分双工（TDD）传输，目前的性能结果，揭示了这一主题的新的光。
英文摘要：
In this paper, we perform a survey on new Third Generation Partnership Project (3GPP) Long Term Evolution-Advanced (LTE-Advanced) enhancements,covering the technologies recently adopted by the 3GPP in LTE Release 11 and those being discussed in LTE Release 12. In more details, we introduce the latest enhancements on carrier aggregation (CA), multiple-input multiple-output (MIMO) and coordinated multi-point (CoMP) as well as three-dimensional (3D) MIMO. Moreover, considering that network nodes will become very diverse in the future, and thus with heterogeneous network (HetNet) being a key feature of LTE-Advanced networks, we also discuss technologies of interest in HetNet scenarios, e.g., enhanced physical data control channel (ePDCCH), further enhanced inter-cell interference coordination (FeICIC) and small cells, together with energy efficiency concerns. In particular, we pay special attention to one of the most important enhancements in LTE Release 12, i.e., dynamic time division duplex (TDD) transmissions, and present performance results that shed new light on this topic.
