Leading the future of network technology

When we join together great things can happen



HERON (HEterogenous Radio and Optical Networks) is an Israeli consortium comprising 13 industrial partners and 15 research teams
from 6 academic institutes. HERON is focused on development of essential building blocks for the 5G next generation Mobile Technology meeting requirements in three major areas - Network E2E Architecture, RAN innovative Network Solutions and essential 5G engines and optimization. HERON consortium is endorsed, funded and operating within the framework of Israel Innovation Authority.

Heron has started its activity on September 2016. HERON consortium has conducted an intensive effort, during its first year work, dedicated to the evaluation of several network architectures and finally an agreed 5G architecture profile is selected.

Heron Consortium

 Heron's participants and its advisory board, following successive brain storming sessions conducted during the first year, have created a potential Eco System solution, aimed at achieving Interoperability among the Engines to be developed by the Heron companies. This Eco System environment will help in developing a coherent Proof of Concept (POC) where a system demonstrator is planned towards end of the three years project.HERON design principles aim to answer the following requirements:

  • Scalability - The system should answer market needs as it evolves. Cost is a prime factor in order to facilitate market penetration

  • Coverage - The system should address firstly Hot Spots and then to spread to cover the entire city

  • Dynamic and Adaptive system - The systems is self-organized and possess dynamic and adaptive features in all situations and applications and support QoE

  • Basic network - Scalable and support simple deployment and maintenance

  • The system engine is composed of high quality engines lend to easy connections and support simple maintenance

  • The system is reliable, distributed or centralized and built by simple connection of engines

  • The system should support COMP, SON, NFV, SDN

  • Interoperability complies with the standard but can utilize undefined components in order to achieve advantage edge

Heron System Architecture

Heron architecture is based on 5 main subsystems:

  1. Virtualized BB processing unit run in Data Centers
All or part of the Base Band (BB) functions means PHY (L1) and Protocol Layers (L2/L3/L4) virtualized (vRAN) and run on one or more central locations (C-RAN). C-RAN center connected to remote RRHs or Smart RRHs.

  1. RRH or sRRH (smart sRRH) - Distributed Units (DU)  
The RRHs could be “dump” without processing capability, or smart RRH with a processing capabilities to run all or part of the BaseBand (BB) functions. sRRH is capable of BS functional split. In case a DU run all or higher BB layers for several sRRH, it is  considered as D-RAN.In order to provide a scalable and modular solution in line with 3GPP definitions and requirements and answering future market needs and technology trends, Heron has defined D-RAN which can be used as a smart RRH or DU enabling complete or partial functionality of the BB units.

  1. Core network - CU
Include all NGC core entities for traffic routing, mobility management, privacy, Subscriber Data Base etc. this section is described more in details see TR 23.501.

  1. High X-Haul (Fronthaul and Backhaul) network
The x-Haul network consolidates both the FH (Front Haul) and BH (back Haul) resources is based on MP2MP network topology that connects different 5G network functions including Mobile Edge Computing (MEC) that may include applications local servers light local management, light 5G NGC, vRAN  D-, or Distributed Units DU D-RAN, or NGC-CU), the sRRH (contains all or part of higher layers of the RAN Protocol stack). The x-haul data will be encapsulated using tunneling techniques over layer 2 Ethernet transport. The x-Haul enable MultiPoint to Multi Point interconnection between any two entities of the entire network, unless CPRI/ORI are used for interconnection between the RRHs and Compact-vRAN or C-RAN based on CPRI or ORI (TBD).

  1. Physical transmission layers
Various Physical transmission layer technologies will be supported, mainly based on Optical Fiber technologies (SFP+(10 Gbps), QSFP+(40Gbps)). The Layer2 transport solution will enable mp2mp connection with high level of multiplexing and load sharing. The same network will handle both FH and BH subnetworks. Figure-1 shows the 5 main subsystems of the Heron system interconnected by several Ethernet rings. The Compact-vRANs can act as a sRRH, or DU, or nano C-RAN, or even several collocated gNBs.

About Heron Consortium


HERON Working Groups


I. System Architecture & Networking Working Group


The System working Group has a system wide-view and in charge of detailed definition and specification of the Heron System
architecture, its required performances and use cases, functionalities, detailed subsystem architecture, interfaces, roadmap and final
PoC planning and integrations. The System working group follows closely the work of the global standardization bodies and Forums, 
main vendor solutions and market trend strategies.

The output of this group serves as an input to R&D teams of HERON who are in charge of the planning and development of subsystems
and interfaces. 


The main activities of the System group are as following:

1.  Review, follow up and evaluation of 5G Global Standardizations, related Forums and Tier-1 companies abroad
     such as 3GPP LTE-A Pro and 5G, IEEE and ITU-T, NGMN, Small Cell Forum, Facebook TIP, AT&T, etc.

About Heron Consortium



HERON Working Groups


II. RAN Working Group


The RAN working group is managed by Dr Zion Hadad from RunEl.

RunEl played an instrumental role from the outset of HERON consortium activity in defining the 5G essential building blocks
(engines) which constitute the major share of HERON research areas and workplan. RAN group is engaged in the design and
implementation of two building blocks (engines) - PHy/MAC and Smart RRH.

The RAN Working Group undertakes close follow up of the progress in the 3gpp standard working group through active
participation in the standard meetings. The RAN group has significant contribution during the evaluation process of different
system concepts and finally, the selection of HERON system Architecture.


Main activities of RAN working group are the following:

1.  Architecture definition and modulation methods for IOT, Massive MTC and M2M. 

2.  Algorithms adaptations to meet 5G specification in terms of power and spectrum efficiency.

3. COMP solutions and resources sharing between smart RRHs and transfer of information between
     the BS in real time using Radio over Ethernet access or other suitable access

4. Development of advanced RRH platform with processing capability aimed to be integrated lately in
    the System Demonstrator (POC). The endowed processing capability should be sufficient in carrying out
    various missions. The RRH demonstrator should be capable of management by SDN, SON or scheduler
    in the cloud, including split in function processing with the computing systems in the cloud and optimized
    by NFV. The smart RRH will include autonomous solutions for cooperation among smart RRH.

5. Develop simulation for real time scheduler capable of assignment the transmission/reception parameters
    for each Resource Block, mapping the levels of transmission matrices, precoding, transmission power etc.
    The scheduler will hold the responsibility for mapping and the dynamic definition of the frame in real time
    (Content awareness) thus enabling 5G applications such as IOT and M2M. 

6. Testing of new correction codes, encryption, MIMO processors and the dynamic Frame of the new integrated
    air interface for 5G, algorithms adaptation and methods for the PHy and MAC layers. 

7. Coordination of the task teams activities mentioned later on - Task team 1 on error Correction Codes,
    Task team 3 - Access and algorithms for MIMO management. Task team 6 on NOMA


III. Dynamic vRAN and Air Interface Algorithms

About Heron Consortium



HERON Working Groups


III. Dynamic vRAN and Air Interface Algorithms Working Group


The vRAN working group is managed by Doron Solomon from ASOCS.

Main R&D tasks are dynamic vRAN and air interface algorithms, as well as future innovative topics.
The group has raised related topics that are not covered in 3GPP forums, but are well discussed, in xRAN, TIP, CORD, etc.  

The group is focused on tasks related to SD-RAN such as: NFV, SDN, orchestration and management, separation, multiple
operators, Open Source, etc. ASOCS, ADVA and Telrad are developing the virtualized part of the SD-RAN. The vRAN group is
addressing the 5G SD-RAN architecture to execute ideas such as Network Slicing, HetNET, with adaptive management for
maximum utilization of resources. 

The group works in accordance with 3GPP standards, smoothly deployed with ONF, ONAP, etc., and in compliance with LSO
as part of the vRAN domain. Advanced local orchestration and management of both NFV and the RAN itself is required for
implementing Content Awareness Function RAN, and QoS-aaS in different types of Network Slicing (Content Awareness,
Application Function Requests, UE requests, etc.), that is based on HetNet with multiple operators. 

Such an architecture requires new network security solutions, and advanced implementation that doesn’t exist today,
although it is covered in the 3GPP protocols and scenarios. 

The above topics are new, and elaboration of the scenarios can be done, and since the consortium includes several companies in
the vRAN/NFV/SDN domains, this work group was established to deal with developing the appropriate air-interfaces, and dynamic
algorithms for such future SD-RAN. The working group has an advantage in developing 5G sub-systems that can be tested in dual-
connectivity mode in accordance with the standard, and therefore is expected to become the market leaders solution that will
impact 5G deployments in the future.

The vRAN working group aims to start testing and integration of the different modules that are developed by the members of the
group as soon as possible, they have already shown successful integration between part of the modules. 

One of the main features of the vRAN architecture is the ability to easily implement different functional splits. This feature enables
broader interoperability such as support of eCPRI FH / RoE FH (IEEE-1914), and older interfaces like CPRI ORI (this is one of the
reasons why the group is also examining non-3GPP groups for interfaces like xRAN, TIP, ETSI, which could lead to future
contributions to the standard). 

The advantages of virtualizing the RAN include dynamic allocation of network resources, with ability to scale at any given time,
and the ability to scale automatically – meaning that a certain vBS that needs more resources could give the orchestrator the
specification of the daughter vBS he needs to create so that it can be optimally integrated into the system.

Assignments of the Dedicated Task Teams


Task Team 1 (led jointly by RunEl and Tsofun)

Error Correction Codes (Polar and LDPC) and LLS Simulation

The task team is assigned to the Investigation of the new version and design considerations of new Polar and LPDC codes
adopted recently as 3GPP standard for 5G system. The task team consider research of new codes with the potential of enhancing
system performance on several aspects and improve performance of codes selected by the standard body.
The task team continues effort of last year undertaken by many industrial partners in achieving a better understanding of 5G
system requirements. Prominent investigators in code theory and implementation methods from academy, Prof. Ido Tal
from the Technion
and Prof. Simon Litsin have joined the task team thereby enriching the scope of the research.
Also, recent entry of Tsofun company to HERON consortium as a partner, on start of second year activity, will enhance the
team work. The expectation is that Tsofun will develop the Polar code and can meet the required performance in terms of
processing time and efficient implementation methods. The same expectation applies to CEVA as a new comer to HERON
consortium in investigating the feasibility of upgraded DSP processors to meet Polar code efficient performance.


Task Team 2 (led by Elbit and Corning)

Antenna development and Multi Carrier FF, and Full Duplex DPD- 

The target is set to reach feasible solution by end of the second year on 60GHz, 14GHz and 3.5GHz 
and reach noticeable advancement on 28GHz solution. 

The research on antenna is widely covered both by academic research teams and industrial partners.
The following is review of promising applied research on antennas conducted in several academic centers in cooperation
with the industrial partners - Research team from Ariel led by Prof Amir Abramovitch is active in developing reflector
antenna for mmw applications and mmw transceivers using signal conversion from laser to mmw using optical devices.
Another applied research on antenna array conducted by research team led by Prof Emanuel Cohen from the Technion
may lead to a breakthrough achievement - "Millimeter wave scalable phased array in CMOS for 5G Wireless
Communication
".

Siklu partner is leading development of the mmw antenna and the RF for application in 60GHz with possible delivery of a
prototype for deployment in POC trial. Siklu is also engaged in 28GHz antenna development conditional to availability of RF
components. Elta expertise in massive MIMO will dedicate appreciable effort in transforming its 14GHz MIMO to the 28GHz
range. Corning is conducting research on efficient implementation methods for multi-antenna arrays in 28GHz and 3.5 GHz
with the required isolation in excess of 60db between transmission antennas and receiving antennas. A study of different
beamforming patters is being conducted at Corning including Hybrid beamforming.

HERON target to achieve 3.5 GHz 4 beams within an area of 40x20 cm seems feasible with isolation of 20 db in side lobs
and resolution of 15 degrees. Another promising area is the study on Full Duplex carried out by CorningElbit and RunEl,
the target of achieving 120 isolation between transmission path and the receiver path and 60 db isolation between adjacent
channel seems feasible.



Task Team 3 (led by RunEl)

Focus on Access, MIMO and Scheduler management algorithms,
SON and COMP over OFDMA

The Task team has a high expectation and set the goal for the second year to achieve an integrated implementation
of 4 layers with 4 digital beams over OFDMA for Up/Down communication link with 200Mhz bandwidth, 1 Gbps throughput
for each beam. The beams will be managed through a simple MAC layer, operating frequency band is either 3.5GHz or
60GHz.

The task team has started its activity in the first year and was engaged in studies for the management of multi Tx/Rx sites
employing multi antennas array with modest number of elements for the low frequency band and high numbers of elements
(reaching 1024 elements) for high frequency range. It is expected that the task team will be highly active in the second year,
will research and simulate various scenarios and coverage patterns. It is worthy to notice that the 5G standard has
intentionally left reserve fields under the title Vendor Specific with the intention to create some differentiation among
vendors. The same for the schedulers. The task team intends in the second year to implement qualitative
differentiation as expected.

Majority of HERON partners are contributing to achieve targets of this Task team:

  •     Both Elta and Siklu will contribute on schedulers and coverage scenarios.
        

  •     Corning on in-door scenarios and coverage.

  •     RunEl will contribute on defining central scheduler for multi-sites in different scenarios
        and the optimization of antenna elements needed in each scenario and introducing SON COMP.

  •     Mobilicom - MIMO integration in aerial scenarios.

  •     Asocs - Central scheduler driving virtual cells with Network Slicing for the implementation of SON,
        COMP and distributed MIMO. The unique feature is that higher layers can manage large number of different L1.


Unique contributions to the Task team from the Academy:

  •     Dr Uri Erez group - Improvement of multicast scheme and possible integration in 5G.

  •     Prof. Shamai group - Distributed algorithms and bounds for the system performance and feasibility
        for use in D-RAN architecture.

  •     Dr Yair NoamBeni Zaidel and Amir Leshem group - CSI compression in different scenarios and algorithms
        modification for D-RAN network.

  •     Prof. Ron Dvora, Performance improvement in presence of cyclic interference.

  •     Pro. Pinchasi research group - different algorithms for the creation of virtual cells with Network slicing
        needed for the implementation of SON, COMP, distributed MIMO.

  •     Prof. Dror Fixler research group - Unique communication schemes for fast change over among various
        NetNet technologies capable of implementing Dual Connectivity while network security is maintained complying
        with future 5G standard.

  •     Dr. Yoram Hadad - Employing artificial intelligence (Machine learning) for the improvement of resources allocation.

  •     Prof. Amir Leshem - The research for the second year will focus on distributed scheduling within constrains for service
        quality and time out for highly sensitive communication to delay. Timing system and resource allocation are
        independent from the standard thus it is highly important relative to the quality of service.

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
