Task Team 4 (led by Galileo)

Time and frequency synchronization and location identification 

The target for the second year is the implementation of clock synchronization scheme over the D-RAN network.
Based on study findings of the first year it seems that each one of the involved partners has achieved a workable solution.
Based on these separate solutions, these solutions will be studied by the task team and try to reach optimized solution
meeting requirement set for different scenarios. Participants in the task team are the following - industrial partners - Galileo,
AsocsAdvaCorningElbit and Telrad. From academy - Prof. Boaz Ben Moshe from Ariel Univ.,
Pinchasi research team from Ariel.


Task Team 5 (led by Mobilicom)

Connected cars and Aerial 

Considering network aspect, the task team is engaged in study of URLLC (Ultra Reliable Low Latency) requirements
and implementation aspects. The task team is focusing on this Use Case due to the requirements to connect subscribers
from different directions and understand the specific requirements in this area including autonomous vehicles. In the aerial
team, Mobilicom was the only driving force, however with setup of a special working group in the 5G standard for Aerial
study, there exist several aspects for further study such as interference and coverage and implications on design of the
New Radio. For 5G, there are many targets to achieve but some of the most important targets are higher throughputs and
low latency. The URLLC is one of the most important to 5G New Radio, this target requires 5G to have E2E latency of less
than 1 msec. in order to reduce the latency, the 5G New Radio introduces a scalable and dynamic structure where the
symbol length can change along with the slot length.



Task Team 6 (led by RunEl)

NOMA

This topic has gained importance by the academic researchers and considered as an interesting area. NOMA is relevant
and most probable to be included in Release 16. This topic was considered in 4G for the DownLink and recently is adopted
for UpLink in case of burst entry for transmission Scheduled free. Elbit is cooperating with prominent researchers from the
Technion and Bar-Ilan University. Researchers within the task team are the following - Prof. Ran Dvora from BGU
working on detectors with a low complexity. Dr Uri Erez, conducting study of a scheme based on Integer Forcing with ML
detector, Prof. Pinchsi research group on evaluation of variety of algorithms, some are relevant for NOMA, work with small
blocks with low latency and low PAPR, specifically useful for IOT and low latency applications, Prof. Shlomo Shamai
research group is working on Sparse NOMA.


Task Team 7 (led by Corning)

Dual Connectivity Research 

The task team supports in-door scenario implementation where Dual Connectivity has to be exercised.
This scenario is one of the essential building blocks in terms of Access Radio.

ASOCS, Partner, ADVA, Telrad, Corning, Elta, Siklu, Elbit are working jointly with research team led by Prof. Dror Fixler
to create a POC project for 5G sub-systems in an indoor environment that could be tested in full Dual Connectivity mode in
compliance with the standard. This research has the potential to impact the standard in the future. ASOCS has joined Tsofun
and Runel, members of HERON consortium, in the 3GPP meetings to understand how the group can maximize the benefits
of the workgroup under the 3GPP umbrella. 

The POC supports the implementation of 5G sub-systems in an indoor scenario that was presented by Corning, which is
planned to be tested in full Dual Connectivity mode in compliance with the standard and the Heron architecture.


Task Team 8 (led by ASOCS)

Network Security Research

Prof. Dror Fixler had significant contribution in network security of the management system and as a result 
Partner is already collaborating with Dror to integrate his solution as part of the general POC. Network security in 5G is
critical for the management of next generation wireless networks. This is based on the fact that in the near future, millions
of devices, which have a different purpose from the smartphones in use today, are going to be connected to the cellular
network.

The success of this technology will be determined based on the reliability and security of the network – an
unsecure system on this network could cause significant financial risks. Although the need for network security in 5G is
clear, these systems today are not secure. For the past few years, companies have worked hard to develop security tools
that are still not at the level of security required and are not at the right price-point, which means that this is still posing a
challenge.

With the help of Prof. Fixler’s research group, we are able to combine a number of tools from different domains
(hardware, software, and unique algorithms) in order to create a reliable, precise, robust and inexpensive tool to secure
5G networks. This tool will be integrated into the PoC of full 5G sub-systems by Partner, and will include implementation of
an alfa system that has been developed by the university using unique tools and an innovative algorithm that enables full
security, including the ability to detect any minor change in the system’s behavior. In tandem, we will develop a system
that will allow us to integrate the academic system in a full cellular network. 

The results shown in previous tests indicate a high probability of success in developing such a tool. Optimizing the academic
tool, then integrating it into the system in the lab, and then taking it to the field with ASOCS-Partner. It can be developed
and to became as an industry-changing tool for precise monitoring and real-time security of 5G networks
