Abstract

The realization of a seamless, fully connected world requires enhancements to our current communications technology, from both a network infrastructure perspective and a user equipment (UE) perspective. These demands are directly driven by the consumer’s expectations, application requirements, and saturation of frequency bands used in current spectrum. The fifth generation (5G) of mobile communication networks, and specifically millimeter-wave (mmWave) New Radio (NR), aims to enable this future with ultra-low-latency, ultra-wideband services, opening up a whole new era of applications and services, much like 4G Long Term Evolution (LTE) did a decade ago. To enable 5G, the Third Generation Partnership Project (3GPP) is focusing on defining the technical specifications for NR technology, as well as enhancements to the current LTE. However, enabling and launching 5G NR presents both technological opportunities and challenges. In this column, we explore how 5G mmWave challenges are being approached in 3GPP standardization and how solutions can enable the technology to help achieve broader bandwidths and harness some of the inherent benefits of higher-frequency communications.

毫米波NR的机遇与挑战

实现一个无缝的、完全连接的世界需要从网络基础设施和用户设备(UE)的角度增强我们现有的通信技术。这些需求是由消费者的期望、应用需求和当前频谱中使用的频段饱和直接驱动的。第五代(5G)移动通信网络，特别是毫米波(mmWave)新无线电(NR)，旨在通过超低延迟、超宽带服务实现这一未来，开辟一个全新的应用和服务时代，就像十年前4G长期演进(LTE)所做的那样。为了实现5G，第三代合作伙伴计划(3GPP)专注于定义NR技术的技术规范，以及对当前LTE的增强。然而，启用和推出5G NR既带来了技术机遇，也带来了挑战。在本专栏中，我们将探讨在3GPP标准化中如何应对5G毫米波挑战，以及解决方案如何使该技术帮助实现更宽的带宽，并利用高频通信的一些固有优势。
