5G From Theory to Practice (5GToP) Workshop

In 2014, the ITU started drafting a timeline for defining the International Mobile Telecommunication system for 2020 and beyond (IMT for 2020 and beyond). This timeline was envisioning that the IMT-2020 to be ready by this year. In accordance to this, 3rd Generation Partnership Project (3GPP) completed 5G Release 16 and approved the OpenAPI specification in July 2020. However, the 5G network provides different features that need to be optimized, in particular, for specific verticals. Thus, 3GPP started the focus on specific applications and leverages on field performance evaluations in Release 17. Currently, 5G is moving from research to deployment in the field. E.g., in 2018 Winter Olympics (Korea), some trials were showcased and in 2020 Olympics (Japan) some additional 5G deployments are expected to be showcased. In Italy, some carriers are announcing the deployment of 5G in the main metropolitan areas.
The 5G from Theory to Practice (5GToP) workshop aims at gathering experts worldwide to discuss about current and planned 5G experimental trials, real deployments, and use cases including the management aspects of 5G networks (RAN/Core Network/Applications). This gathering will also be a chance to discuss about future generation mobile network (6G) based on what 5G is lacking and what different verticals need.

Keynote Talk

Keynote: Prof. Akihiro Nakao, Professor, Graduate School of Interdisciplinary Information Studies, the University of Tokyo
Title: Democratizing Beyond5G/6G
Abstract: In Japan, Commercial 5G service has started in the spring of 2020 while 5G telecommunication services have been already globally deployed and utilized. At the same time, in each country, a strategy aiming at 6G is already in progress, and in Japan, the direction of research and development is being discussed under the name beyond5G/6G. Also, several counties have allocated white space to private 5G usage, and open to non-telecommunication companies so that they can operate their own customized 5G networks. We posit that this democtratization trends will open a door to the innovations towards 6G.
In this presentation, introducing local 5G activities in Japan that have caught very much attention from industries together with our lab’s research activities around 5G and local 5G, we discuss an evolution path from private 5G to private 6G and then to public 6G.

Invited Talks:

Invited Talk 1: Prof. Kiran Kuchi, Founder WiSig Networks and Professor, IITH Hyderabad, India.
Title: 5G Developmental Journey @WiSig Networks
Abstract: WiSig Networks Pvt Ltd (WiSig), a startup incubated at IIT Hyderabad (IITH) technology incubator, is beginning to cement its place in the 5G market space, through development of cutting-edge technologies like Massive MIMO (mMIMO), ORAN 5G base station comprising of DU (Distribution Unit) and RU (Radio Unit) with sub 6GHz and mmwave support, NB-IoT SoC (System-on-Chip) production, IP (Intellectual Property) supply and licensing. WiSig with deep expertise in physical layer and protocol stack, holds a strong 5G patent portfolio that offers significant differentiation and value addition.
WiSig is working on the development of a radio access network based on an emerging disruptive technology called ORAN (Open-Radio-Access-Network), that is being touted as the next major disruptor in the 5G landscape. This technology allows development and rapid deployment of low-cost, software upgradable, 5G base stations in significantly higher volumes and larger densities than current 4G network. ORAN is a software defined 5G system based on open interfaces, and general-purpose hardware. Some operators have initiated deployment of ORAN based soft-ware-defined network (SDN) and visualization networks that enable self-organization, low operational cost, ease of introduction of new features and service upgrades. New 5G use cases can be introduced rapidly on the fly using software upgrades as opposed to costly and time-consuming hardware development cycles.
WiSig has recently demonstrated the one of the first ORAN compliant demonstrations of full 5G baseband at CEATEC, Tokyo, Japan during 2019 followed by a yet another show at Mobile World Congress (MWC) USA, LA 2019. WiSig demonstrated ORAN compliant baseband including mMIMO reference design at these trade shows. On the IoT side, WiSig Networks is developing a 3GPP standards compliant NB-IoT SoC in cooperation with IIT Hyderabad. This chip includes NB-IoT modem, GNSS (GPS) radio and an application processor. This solution can serve the security needs of critical national IoT infrastructure involving use cases such as Electricity, Water, Gas, Defence, public safety and other smart city applications.
This talk outlines the 5G developmental journey at WiSig Networks.
Bio: Dr. Kiran Kuchi, a professor at IIT Hyderabad (IITH), is a globally recognized innovator in the realm of 5G standards development. He has introduced the culture of developing wireless Standards Related Patents in India through his leadership role at Telecom Standards Development Society, India (TSDSI) and has contributed towards the creation of several important technologies in the 5G standards. Dr. Kuchi has invented & co-invented over 100 patents in the 4G/5G technology, of which many patents have resulted from his work carried out in India. Among these patents, his most well recognized contribution is the introduction of a low PAPR (almost constant OFDM signal) waveform: “pi/2 BPSK with spectrum shaping” that is part of the 5G standard. Dr. Kuchi’s yet another significant achievement is the development of one of the first large scale prototypes of massive MIMO technology that operates either as an outdoor Massive MIMO, or as a distributed small cell cloud RAN system. This experimental research system has been operational since 2017 at IIT Hyderabad. Prof. Kuchi founded WiSig Networks, a wireless startup that specializes 5G wireless IP at IITH technology incubator in 2016.

Title: Transport for Industry 4.0: shared networks and 5G slicing transport aware
Abstract: Most of the relevant use cases for Industry 4.0 are based on Stand Alone Networks that are delivered on the vertical premises in order to meet latency requirements. In order to reduce total cost of ownership and enable novel use cases, it is very relevant to define solutions that allows to support such use cases in a shared network while assuring the same performance of dedicated network. Qualifying ingredient for realizing a shared network are two: a suitable transport networks based on optical technology combined with slicing technique that is transport aware. This presentation shows a concrete example of a shared networks that is carried out in the framework of the H2020 European project “5Growth” that is based on WDM transport and extends the 5G slicing architecture with the transport. Implementation on a PoC is also reported.
