Beginners: Introduction to 5G Reduced Capability (RedCap) Devices3G4G
A quick introduction to new 3GPP Release-17 feature called RedCap or Reduced Capability New Radio devices. This feature was earlier called NR-Light / NR-Lite and is sometimes referred to as Low Complexity NR devices.
This tutorial looks at why this is needed, how is it different from the existing 5G requirements for eMBB, URLLC & mMTC, and why can't 4G be used instead of 5G for this feature.
We will also look at some of the proposals for enhancement of RedCap that are being discussed for 5G-Advanced in 3GPP Release-18

Over the last year, the industry has made tremendous progress towards making 5G NR a reality with Qualcomm leading the way. We have completed the first release of 3GPP 5G NR specifications, we are set to kick-off 3GPP-compliant 5G NR trials, and we are accelerating global 5G NR enhanced mobile broadband commercial deployments to start in 2019.
But yet there still remains a decent amount of mystery and skepticism around 5G NR. What exactly is 5G NR? What technologies and use cases will see first and why? Are wide-scale 2019 mobile deployments really possible? And what will the evolution of 5G NR bring beyond 2019?

In the future factory robots will communicate wirelessly and cars on the highways will exchange the information with each other. This requires extremely low latency mobile networks, known as 5G. This network will run on telco grade cloud platforms of which OPNFV is one example.
The first cloud radio access networks have already been deployed to operators. More is needed with future technologies/networks as more functionalities will be moved to the cloud. This talk tells what is needed to overcome low latency and high availability challenges with cloud platforms. At Nokia we are continuously evaluating the latest OPNFV SW on Nokia HW with radio VNFs to guarantee interoperability with open source components.
We have seen all the mobile broadband technologies like 1G, 2G, 3G and most recent 4G and upcoming is 5G. And they were very successful and motivated by the need to meet the requirement of the mobile users.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

18. Drivers For Next Generation (5G)
Growing Population
Hyper Connectivity
Limited Resources
Higher Capacity
Green Technology
Cost Efficiency
Quality of Experience
Number of connections and also the volume of data over
wireless networks continuously growing at a significant rate
Users more demanding on quality & price
Capacity challenge is real particularly in radio
Radio spectrum the blood line of wireless is a finite resources,
scarce and expensive
The data volume growth will continue but dependent on the
service quality offered by the NW and of course the data tariffs
Sustainability of mobile broadband business - Ever increasing
traffic, higher TCO and flattening ARPU
3G & 4G both promised improvements in NW capacity, data rate,
efficiency, cost and quality. 5G will be no exception but the sheer
scale of the challenges this time makes 5G research different.

20. Significant air interface capacity
-Focus on area NOT JUST link spectral efficiency
-Designed for small Cells (capacity), extended to coverage
-More spectrum (Licensed & unlicensed operation, spectrum
sharing & other sources)
Super low latency
- Sub 1 ms, TTI: 10-25 ms
-Faster signaling for higher data rate, in line with data rate
-U plan latency: frame structure, control signal timing, HARQ
-For new services (MTC, gaming, ….)
-For distributed control
Super reliable
-For new services and applications
-Smart transport, e-health, intelligent control, …
The higher capacity and lower latency necessary for wide
range of services BUT not all the services required in the
same location, at the same time nor by the same air interface
May need tradeoffs in
capacity, coverage and data rate

technologies
• 5G will change the system architecture, especially the RAN
• A much denser network (small cells) will be key to 5G
design
• Spectrum remains a challenge for the wireless industry;
spectrum sharing will be critical
• A greater degree of network sharing may be needed in 5G
• 5G success depends rethinking business models, policies
and economics of radio spectrum regulation
