<\/span><\/figcaption><\/figure> NEW DELHI: Licensed spectrum is one of the most valuable assets any mobile communications network operator has. Implementing and evolving a system on existing and new spectrum, is one of the most critical parts of 5G<\/a>. The list of challenges is quite long and Kailash Narayanan<\/a>, VP and General Manager of Keysight Technologies<\/a>’s wireless test group in a chat with ETTelecom explained how telcos can navigate through them.
<\/em>
What are the challenges that telcos are going to face during 5G transition?<\/b>

There are many challenges but we can focus on mmWave, mid-band spectrum, and Non-Standalone to Standalone (NSA\/SA) transition. First is the addition of mmWave spectrum. This gets more headlines than other spectrum issues because it represents one of the largest changes and demands for new technology in 5G.

Enabling communications in this spectrum has been discussed at length. First, this requires access to the spectrum. So far, this so-called “FR2” spectrum has been allocated and\/or auctioned only in the US, Japan, and South Korea.

Policymakers elsewhere are working through auction and allocation issues and we will see more of these decisions being made (but by no means all of them) in 2020. Secondly, it requires new base stations and new UE capabilities which mean new cell and network planning.

The only commercial systems running now are for fixed-wireless access—the UE does not move. The ability to manage mobility in this space is not ready yet. Regarding the standards, so such work must be resolved and completed before systems are deployed—it usually takes 12-18 months between completed work in the standards and when commercial systems are deployed.

Is Keysight Technologies testing mmWave and developing solutions?<\/b>

Keysight has been involved in mmWave test and measurement for quite a while now and we have built capabilities in our solutions to enable customers to ensure their systems are behaving as designed and behaving consistent with the standards.

What are the challenges associated with evolving systems on the mid-band spectrum?<\/b>

The addition of mid-band spectrum (2.5-5GHz) for mobile wireless seems to many like a simple extension of existing work done in previous generations. However, there are new challenges here—license allocation is largely complete in countries outside of the US. In the US, there are still many issues related to either already-allocated Citizens’ Broadband Radio Service (CBRS) spectrum related to co-primary use of licenses and other shared spectrum issues.

In addition, there are policy conflicts currently under way relating to other mid-band spectrum areas in the US that will take a few years to resolve. The technical challenges related to these higher frequencies must do with wider bandwidths and link-budget problems on the uplink. Trials and early deployments show a different in link-budget in uplink vs. downlink of upwards 18dB—this means that signal-to-noise-and-interference ratios on the uplink require significant improvements to maintain the appropriate link.

This is complicated by new use-models in 5G with higher demand on the uplink than the downlink (this is new to mobile communication). Overcoming these issues means added design constraints on both the UE and gNB, and more-importantly, the implementation of new antenna systems; especially those related to massive MIMO<\/a>.

How is Keysight and other T&M (test and measurement) companies approaching this transition?<\/b>

These are new, relatively expensive, and power-hungry systems, as well as antenna systems, that require different physical mounting schemes. Keysight’s approach to these are to ensure that our capabilities are fully deployed for the testing of these new bands and bandwidths, as well as the solutions we have in place to validate the rest of the network (UE emulation).

What are the other likely spectrum-related implementation issues during 5G deployment?<\/b>

T<\/b>he early implementation of 5G is a non-standalone system with an LTE<\/a> core controlling both a 4G and 5G RAN. Ultimately, operators will be moving to SA systems to take full advantage of the new capabilities in the 5G core. This may seem like a large transition in the packet core network called the next-generation core (NGC) in 5G and wired-parts of the Radio Access Network (RAN) - it is.

However, it has significant spectrum-related implementation issues. During the transition, operators might be opening 5G NR connections in the same bands as with 4G connections. Ultimately operators will be migrating 4G RAN to 5G RAN, hence, having to make an LTE to NR transition for existing bands. This is always a challenge that must be managed carefully. In addition to having the right RF test capabilities for these bands.

新德里:授权频谱是最有价值的资产之一任何移动通信网络运营商。实现和发展一个系统在现有的和新的频谱,是最关键的部分之一5克。挑战的名单很长,凯拉什Narayanan副总裁和总经理Keysight技术的无线测试组在一个聊天ETTelecom解释了电信公司可以浏览它们。乐动娱乐招聘
电信公司将会面临的挑战是什么5 g过渡期间?

有许多挑战,但我们可以专注于mmWave, mid-band频谱,Non-Standalone独立(NSA / SA)过渡。首先是添加mmWave频谱。这比其他光谱问题得到更多的头条新闻,因为它代表了一个最大的变化和新技术的要求5 g。

使通信光谱中讨论。首先,这需要对光谱的访问。到目前为止,这所谓的“FR2”频谱分配和/或拍卖只在美国、日本、和韩国。

其他地方的政策制定者正在通过拍卖和分配问题,我们将看到更多的这些决定的(但不是全部)在2020年。其次,它需要新基站和新问题的能力意味着新的细胞和网络规划。

现在唯一的商业系统运行是固定无线问题进行访问不动。管理流动性的能力在这个领域还没有准备好。有关的标准,所以这些工作之前必须解决和完成系统部署它通常需要12 - 18个月完成工作之间在标准和商业系统部署。

mmWave Keysight技术测试和开发解决方案?

Keysight参与mmWave测试和测量相当长一段时间了,我们已经构建了功能在我们的解决方案,使客户以确保他们的系统作为设计和行为表现符合标准。

哪些挑战与发展系统mid-band谱吗?

添加mid-band移动无线频谱(2.5 5 ghz),一个简单的扩展现有的工作在以前的几代人。然而,有新的挑战here-license分配主要是在美国以外的国家完成。在美国,仍有许多问题要么作为公民的宽带无线电服务(cbr)光谱相关co-primary使用许可证和其他共享频谱问题。

此外,还有其他相关政策冲突目前mid-band光谱区域在美国还需要几年的时间才能解决。相关的技术挑战这些更高频率必须与更广泛的带宽和上行链路预算问题。试验和早期部署显示不同的上行和下行链路预算中向上18 db-this意味着signal-to-noise-and-interference比率在上行要求显著改善保持适当的联系。

这是复杂的新需求较高的5 g中使用模型在上行下行(这是新的移动通信)。克服这些问题意味着增加了设计约束问题和gNB,更重要的是,新的天线系统的实施;尤其是那些大有关米姆。

如何Keysight和其他T&M(测试)公司接近这种转变?

这些都是新的,比较昂贵,和权力系统,以及天线系统,需要不同的物理安装方案。Keysight的方法,这些都是为了确保我们的能力是完全部署的测试这些新的乐队和带宽,以及我们的解决方案来验证网络的其余部分(问题模拟)。

其他可能spectrum-related 5 g部署期间实现问题?

T他早期的实现5 g是一个non-standalone系统LTE核心控制4 g和5克。最终,运营商将搬到SA系统充分利用新功能5 g的核心。这可能看起来像一个大转变的分组核心网络称为下一代核心(NGC)在5 g和wired-parts无线接入网络(RAN)——它是。

然而,它具有显著的spectrum-related实现问题。在过渡期间,运营商可能会打开5 g NR连接在同一个乐队与4 g连接。最终运营商将迁移4 g跑到5克,因此,必须使LTE NR过渡为现有的乐队。这始终是一个挑战,必须认真管理。除了这些乐队的射频测试能力。
