5G NR: The Next Generation Wireless Access Technology 电子书读后感

评分☆☆☆☆☆

以下八项参数被视为IMT-2020的关键能力： 1）峰值数据速率每个用户（或者设备）在理想条件下可以获得的最大数据速率（单位：Gbit/s）。 2）用户体验到的数据速率在信号覆盖范围内的任何地点上，移动用户（或者设备）都能够获得的数据速率（单位：Mbit/s或者Gbit/s）。 3） ...

评分☆☆☆☆☆

IMT-2020的峰值数据速率应该达到10 Gbit/s。但是，在特定条件和场景下，IMT-2020支持最高达到20 Gbit/s的峰值数据速率。在多种移动宽带增强（eMBB）的场景下，IMT-2020需要支持不同的用户体验到的数据速率。在广域覆盖的场景，比如市区和郊区场景，用户体验到的数据速率需要达...

5G NR: The Next Generation Wireless Access Technology 2024 pdf epub mobi 电子书图书描述

5G NR: The Next Generation Wireless Access Technology follows the authors' highly celebrated books on 3G and 4G by providing a new level of insight into 5G NR. After an initial discussion of the background to 5G, including requirements, spectrum aspects and the standardization timeline, all technology features of the first phase of NR are described in detail.

Included is a detailed description of the NR physical-layer structure and higher-layer protocols, RF and spectrum aspects and co-existence and interworking with LTE. The book provides a good understanding of NR and the different NR technology components, giving insight into why a certain solution was selected.

Content includes:

Key radio-related requirements of NR, design principles, technical features

Details of basic NR transmission structure, showing where it has been inherited from LTE and where it deviates from it, and the reasons why

NR Multi-antenna transmission functionality

Detailed description of the signals and functionality of the initial NR access, including signals for synchronization and system information, random access and paging

LTE/NR co-existence in the same spectrum, the benefits of their interworking as one system

The different aspects of mobility in NR RF requirements for NR will be described both for BS and UE, both for the legacy bands and for the new mm-wave bands

Gives a concise and accessible explanation of the underlying technology and standards for 5G NR radio-access technology

Provides detailed description of the NR physical-layer structure and higher-layer protocols, RF and spectrum aspects and co-existence and interworking with LTE

Gives insight not only into the details of the NR specification but also an understanding of why certain solutions look like they do

5G的目标愿景是：信息获取和数据共享能够在任何地方anywhere、任何时间anytime和任何物体anything上实现。和现有的4G系统相比，5G系统的技术能力为： 1）单位面积内的移动数据流量提高1000倍； 2）连接设备的数量提高10倍到100倍； 3）用户的特定数据速率提高10倍到100倍； 4）对低功耗大规模机器通信设备来说，电池续航时间提高10倍； 5）端到端时延减少5倍；另外，5G需要克服的一大挑战是，上述技术目标必须在与4G系统产不多的成本和能耗效率的前提下实现。
