LTE The UMTS Long Term Evolution

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.

Long Term Evolution

A GSM, and its evolution through GPRS, EDGE, WCDMA and HSPA, is the technology stream of choice for the vast majority of the world’s mobile operators. Today’s commercial offerings which are based on this technology evolution typically offer downlink speeds in the order of 7 Mbps, with the expectation that 14 Mbps will become widely available in the near future.With such an improvement in 3rd Generation (3G) capabilities, there are obvious questions to be asked about what should happen next. From a standardization perspective 3G work is now well-advanced and, while improvements continue to be made to leverage the maximum performance from currently deployed systems, there is a limit to the extent to which further enhancements will be effective. If the only aim were to deliver higher performance, then this in itself would be relatively easy to achieve. The added complexity is that such improved performance must be delivered through systems which are cheaper to install and maintain. Users have experienced a dramatic reduction in telecommunications charges and they now expect to pay less but to receive more. Therefore, in deciding the next standardization step, there must be a dual approach: seeking considerable performance improvement but at reduced cost. LTE is that next step and will be the basis on which future mobile telecommunications systems will be built.

LTE - The UMTS Long Term Evolution 2nd Editio

LTE（Long Term Evolution，长期演进)是由3GPP（The 3rd Generation Partnership Project，第三代合作伙伴计划）组织制定的UMTS（Universal Mobile Telecommunications System，通用移动通信系统）技术标准的长期演进，于2004年12月在3GPP多伦多会议上正式立项并启动。LTE系统引入了OFDM（Orthogonal Frequency Division Multiplexing，正交频分复用）和MIMO（Multi-Input & Multi-Output，多输入多输出）等关键技术，显著增加了频谱效率和数据传输速率（20M带宽2X2MIMO在64QAM情况下，理论下行最大传输速率为201Mbps，除去信令开销后大概为150Mbps，但根据实际组网以及终端能力限制，一般认为下行峰值速率为100Mbps，上行为50Mbps），并支持多种带宽分配：1.4MHz，3MHz，5MHz，10MHz，15MHz和20MHz等，且支持全球主流2G/3G频段和一些新增频段，因而频谱分配更加灵活，系统容量和覆盖也显著提升。
