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.
