摘要

在“万物互联”愿景的驱动下，国际电信联盟为5G提出了高速率、低时延、海量连接三大应用场景以及相关的性能指标需求。相应地，国际标准组织3GPP中完成了具体技术研究和标准化，形成了5G新空口的设计。首先，对于为何5G新空口设计可以重用LTE的基础设计进行了分析，亦即MIMO-OFDM的框架是如何满足国际电信联盟定义的三大需求的；其次，对5G新空口与LTE的重点差异进行了总结，包括新架构、新设计、新频段、新天线 “四新”的具体内容。最后对未来技术发展趋势做了简单的介绍。

Abstract

Driven by the 5G visions including “wireless infrastructure to connect the world”

ITU has defined the three main usage scenarios of 5G: eMBB

mMTC

and uRLLC

and the consequent requirements (performance metrics) are defined as well. Then

3GPP completed technical studies and standards towards satisfying ITU requirements

namely 5G new radio (NR). Two essential aspects of 5G NR were discussed. Firstly

why can 5G NR reuse the basic technology of 4G LTE was discussed

i. e.

how does the MIMO-OFDM framework satisfy ITU 5G requirements. Secondly

what innovations had been done in 5G NR

comparing with LTE

including some details on the four new features of 5G NR

namely “new architecture

new design

new bands

new antenna”. The future technology trends were briefly introduced in the conclusion section.
