A comprehensive summary of theoretical and practical developments in LTE Heterogeneous Networks

The last decade has witnessed the proliferation of mobile broadband data and the trend is likely to increase in the coming years. Current cellular networks are ill equipped to deal with this surge in demand. To satisfy user demand and maximize profits, a new paradigm to operate networks is needed. Heterogeneous networks, that deploy an overlay of small cells with limited coverage and transmit power, over a macro coverage area is the solution by providing capacity and coverage where it is needed.

This book presents a comprehensive overview of small cell based heterogeneous networks within the framework of 3GPP LTE-Advanced which is the major enabler of current and future heterogeneous networks. The book first establishes the basics of LTE standards 8 -10. Wherever relevant, the underlying theory of wireless communications is explained and the signaling and protocol aspects of LTE Releases 8-10 are presented. Next the book presents a systematic study of the inter cell interference (eICIC and FeICIC) mechanisms that have been standardized in LTE releases 10 and 11 to mitigate the interference arising in heterogeneous networks. From simple blank subframe design and implementation, the book discusses more advanced transceiver signal processing and carrier aggregation (CA) based mechanisms to improve performance. Besides data, control channel enhancements such as enhanced PDCCH (ePDCCH) are also discussed.

Subsequently the book discusses the possibility of base stations being allowed to coordinate to manage interference. This technique, called CoMP, has the potential of vastly improving network performance. However several practical challenges first have to be overcome before this potential can be realized. The book presents the different CoMP categories introduced in LTE release 11, the required signal processing and the changes that were introduced in Release-11 for supporting CoMP. The book then presents the state of the art developments in heterogeneous networks that are currently taking place in 3GPP with the initiation of Release 12. A whole array of new technologies have been introduced such as dynamic switching of small cells, new carrier types with reduced control signaling, dynamic reconfiguration of TDD-LTE, joint configuration of TDD and FDD via carrier aggregation and lastly advanced MIMO signal processing with three dimensional beamforming. All these technologies will work in unison leading to efficient operations of small cells.

The authors thus comprehensively summarize the advances in heterogeneous networks over the last couple of years as reflected in various LTE releases and then look ahead at what to expect in the future. Fully illustrated throughout and with an accompanying website including Matlab code for simulating heterogeneous networks, LTE channel models, and References to 3GPP specifications, contributions, and updates on recent standardization activities. The authors, being involved in LTE standardization, are well placed to give an excellent view on this topic, including valuable background and design rationale.

《LTE異構網路的理論和實踐發展的全面總結》

過去十年見證了移動寬頻數據的大量增長,而這一趨勢在未來幾年可能會繼續增加。目前的蜂窩網絡無法應對這一需求激增。為了滿足用戶需求並最大化利潤,需要一種新的網絡運營範式。異構網絡是一種解決方案,它在宏觀覆蓋區域上部署具有有限覆蓋範圍和傳輸功率的小型蜂窩,以提供所需的容量和覆蓋範圍。

本書在3GPP LTE-Advanced框架下全面介紹了基於小型蜂窩的異構網絡,這是當前和未來異構網絡的主要推動者。本書首先建立了LTE標準8-10的基礎。在適當的地方,解釋了無線通信的基本理論,並介紹了LTE Releases 8-10的信令和協議方面。接下來,本書系統地研究了在LTE Releases 10和11中標準化的干擾區間內干擾消除(eICIC和FeICIC)機制,以減輕異構網絡中出現的干擾。從簡單的空白子幀設計和實施,本書討論了更高級的收發信標號處理和基於載波聚合(CA)的機制以提高性能。除了數據外,還討論了增強的PDCCH(ePDCCH)等控制信道增強。

隨後,本書討論了允許基站協調管理干擾的可能性。這種技術被稱為CoMP,有望大大提高網絡性能。然而,在實現這一潛力之前,必須先克服幾個實際挑戰。本書介紹了LTE Release 11中引入的不同CoMP類別,所需的信號處理以及為支持CoMP而引入的變化。然後,本書介紹了當前正在3GPP中進行的異構網絡的最新發展,這是在Release 12的啟動下進行的。引入了一系列新技術,例如小型蜂窩的動態切換、具有減少控制信令的新載波類型、TDD-LTE的動態重配置、通過載波聚合的TDD和FDD的聯合配置,以及先進的三維波束成形的MIMO信號處理。所有這些技術將協同工作,實現小型蜂窩的高效運營。

作者們全面總結了過去幾年異構網絡的進展,這些進展反映在各種LTE版本中,並展望了未來的發展。全書配有插圖,並附有一個網站,包括用於模擬異構網絡的Matlab代碼、LTE信道模型以及對3GPP規範、貢獻和最新標準化活動的參考。由於參與了LTE標準化工作,作者們在這一主題上具有豐富的經驗,能夠提供有價值的背景和設計理念。
