一篇相当不错的描述TD LTE中 beamforming 波束赋形技术的论文。

基站和直放站等设备的射频测试采用的都是矢量信号源和信号分析仪的方法。以LTE基站射频测试为例，厂商利用矢量信号源产生LTE上行

载波聚合的关键技术： CA功能可以支持连续或非连续载波聚合，每个载波最大可以使用的资源是110个RB。每个用户在每个载波上使用独立的HARQ实体，每个传输块只能映射到特定的一个载波上。每个载波上面的PDCCH信道相互独立，可以重用R8版本的设计，使用每个载波的PDCCH为每个载波的PDSCH和PUSCH信道分配资源。也可以使用CIF域利用一个载波上的PDCCH信道调度多个载波的上下行资源分配。

LTE: The UMTS Long Term Evolution provides the reader with a comprehensive system-level understanding of LTE, built on explanations of the theories which underlie it. The book is the product of a collaborative effort of key experts representing a wide range of companies actively participating in the development of LTE, as well as academia. This gives the book a broad, balanced and reliable perspective on this important technology. Lucid yet thorough, the book devotes particular effort to explaining the theoretical concepts in an accessible way, while retaining scientific rigour. It highlights practical implications and draws comparisons with the well-known WCDMA/HSPA standards. The authors not only pay special attention to the physical layer, giving insight into the fundamental concepts of OFDMA, SC-FDMA and MIMO, but also cover the higher protocol layers and system architecture to enable the reader to gain an overall understanding of the system.
