NGMN 5G Devices SA Migration Scenarios

To ensure the coexistence of 5G and 4G Devices, enabling the use of the new 5G Core Network, operators need to manage a transition period in which both 5G deployment architectures are present.

Taking a devices perspective, this white paper looks specifically at how Mobile Network Operators (MNOs) who currently operate 4G and 5G Non Standalone (NSA) networks can evolve to support 5G Standalone (SA) networks.

This paper presents a way to handle and optimize this transition. The goal is not only to guarantee an effective usage of the most valuable FDD and TDD Sub-6 bands (< 6GHz) but also effective usage of all frequency assets.

The re-farming strategies that can be implemented by Operators will inevitably be influenced by the speed of penetration of 5G Devices and the frequency bands that they support. Accordingly, a potential migration timeline has been defined.

 

NGMN 5G TDD Uplink White Paper v1.0

5G TDD Uplink v1.0

This White Paper contemplates the challenges for Vertical Industries to achieve sufficient uplink throughput or cell capacity and low enough latency for their industrial use cases, when using 5G TDD bands for the realization of those use cases. After looking into the problem, various technical solutions are being considered, some of them providing solutions for the management of interference between base stations or mobile handsets, when deviating frame structures are being used to support the industries’ requirements. The document concludes with specific recommendations to regulators and mobile industry partners who want to support the industry with adequate solutions.

NGMN CALLS FOR THE INDUSTRY TO SUPPORT UPLINK PERFORMANCE

Frankfurt, Germany, February 16, 2022: Verticals’ use cases need sufficient uplink throughput or cell capacity and low enough latency, when 5G Time-Division Duplex (TDD) bands are used to successfully realize their industrial use cases. The uplink performance is key to fully unlock the value of 5G. Therefore, the Next Generation Mobile Networks (NGMN) Alliance calls to increase efforts to enhance the uplink performance in its new White Paper “5G TDD UPLINK”. The Alliance formulates specific recommendations to regulators and other mobile industry stakeholders to support the ecosystem with adequate solutions. Also, various technical possibilities are presented – some of them are related to the management of interference, when differing frame structures are used to support the industries’ requirements.

Wolfgang Fleischer, Head of Network Innovation Technology & Business Evolution, A1 Group, NGMN Board Member and project lead, says: “Some of the applications for 5G technology, particularly in industrial settings, have greater requirements on the uplink – both in terms of capacity and shorter latency. This NGMN Initiative puts these into the spotlight and presents features to enable the networks to accommodate the requirements for such uplink dependent use cases.”

NGMN’s recommendations to better support the uplink throughput and latency requirements of Verticals include:

  • To use different TDD configurations
  • To select frame structure to vary uplink/downlink throughput
  • To carefully select more balanced or uplink oriented TDD frame structures in a local network
  • To consider the adoption of other uplink enhancing features such as SU-MIMO
  • To enhance 3GPP specification to fulfil requirements with respect to UL throughput, latency, and support for the co-existence of different frame structures by enhancements
  • To reserve spectrum for certain specific usages

The NGMN project will also reach out to chipset makers, regulators, Standard Developing Organisations and other involved parties to ensure that these NGMN recommendations are considered.-ends-

Further information and NGMN recommendations:

  1. A number of verticals’ use cases require significantly higher uplink throughput and lower latency than that required by typical Mobile Broadband consumer mobile users. There are solutions available to address this uplink problem (throughput and latency). Using different TDD configurations, as one of the solutions, requires coordination between operators in order to minimize possible interference and support by regulators to achieve sufficient operational flexibility to deliver customer use cases with higher uplink requirements.
  2. Frame structure selection is an effective way of varying uplink/downlink throughput. Additional balanced or uplink oriented frame structures should be made available and interoperable by ecosystem partners (chipset, user equipment and infrastructure providers). NGMN has identified specific slot formats, DDSUU (balanced) and DSUUU (uplink oriented), as candidates for specific frequency ranges (FR1 and FR2). Ecosystem partners should also support operators in making available and interoperable other possible alternative solutions identified in this White Paper to address this uplink problem.
  3. Careful selection of more balanced or uplink oriented TDD frame structures in a local network is recommended to limit the interference impact between local and wide-area public networks. However, if isolation between networks is sufficient (through physical separation, indoor with sufficient wall penetration loss, guard bands, etc.), the selection and use of TDD frame structures are less constrained and may be beneficial for services with a more balanced or uplink oriented traffic profile.
  4. In scenarios where sufficient isolation between networks is not achievable, e.g. local outdoor networks in the same or adjacent spectrum, using different TDD frame structures will be extremely difficult, if not impossible. In such cases, adoption of other uplink enhancing features such as SU-MIMO (Single-User Multiple Input Multiple Output) and MU-MIMO (Multi-User Multiple Input Multiple Output) should be considered.
  5. Future 3GPP specification enhancements, including 5G advanced and 6G, should ensure the requirements of verticals’ use cases are fulfilled with respect to UL throughput, latency, and support for the co-existence of different frame structures.
  6. Spectrum, particularly sub 6 GHz, is a critical and limited resource for mobile communications. Regulators need to carefully consider how it is assigned to ensure it can be used effectively and efficiently. Spectrum fragmentation due to reservation for certain specific usages could undermine the assignments of sufficiently large contiguous frequency blocks for 5G networks, potentially leading to under-utilization and spectrum inefficiency.

NGMN Claims Pole Position in Disaggregation Operating Model, Green Networks and 6G

Frankfurt, Germany: Today, the Next Generation Mobile Networks (NGMN) Alliance announces its new strategy and claims pole position in addressing the key major Operator & Ecosystem challenges in the coming years.

As an operator driven organisation, NGMN is in a unique position to provide value, guidance and leadership to its members and the whole ecosystem in:

  • Mastering the route to Disaggregation
  • Sustainability / Green Future Networks
  • 6G

Anita Doehler, CEO NGMN, says: “Operators are facing challenges on their route to disaggregation, cloudification and softwarization. One burning topic in this area is the design and execution of effective new E2E operating models. Green Future Networks is another highly important topic the industry ecosystem needs to jointly approach. In addition, early work on 6G has started. Therefore, we have streamlined our Work Programme to focus on these three extremely relevant topics to deliver significant impact in 2021 and beyond. At the same time, we remain committed to further support 5G’s full implementation.”

Mastering the Route to Disaggregation

For mastering disaggregated, cloud- and software-based networks, Mobile Network Operators need to start preparing now for future-proof operating models that are built on the orchestration of powerful ecosystems of solution partners, openness and flexibility to integrate new partners and technologies, highly diverse set of skills and capabilities to drive value and efficiency. NGMN’s new Work Programme will thus focus on the end-to-end operating model, considering, amongst other, the following key aspects: processes, technology, tools and skill requirements. NGMN will provide blueprints as well as relevant guidance towards the industry players and lay out roles and opportunities provided by disaggregation. The initiative aims to shorten time to market and to provide support in the selection and deployment of efficient operating models by Mobile Network Operators.

Providing Impactful Guidance for Green Future Networks

The application of various techniques to improve network energy performance is one fundamental objective for Mobile Network Operators since the number of users, connected devices and general usage continue to grow. The ICT network consumes the most energy in the content delivery process and electricity represents our principal source of greenhouse gas emissions. An additional objective is waste reduction, amongst other enabled by the eco-design of products and equipment. To tackle such important topics, this well-established NGMN project focuses on four major aspects: end-to-end services footprint, eco design, network energy efficiency and on-board metering. Consolidating a common view amongst operators and collaborating with equipment vendors and other industry players enables NGMN to provide a significant industry contribution in achieving UN and GSMA sustainability goals. NGMN plans to release frequent impactful guidance on sustainability to the ecosystem.

 Driving Successful Implementation of 6G

Work focusing on beyond 5G has already started worldwide. The NGMN Alliance strongly believes that societal and operational requirements need to be considered in the development of a new generation. Operators are in a unique position to engage with end users, including vertical industries as well as user groups representing societal needs. The NGMN Alliance is determined to provide early and timely direction for global 6G activities. Its 6G Work Programme currently focuses on vision and drivers, including societal and operational aspects for 6G. This will be followed by use cases and end-to-end system requirements. Actively engaging with different stakeholders and facilitating multilateral cooperation with the wider ecosystem at the right time will support in developing a meaningful vision and drive a successful implementation of 6G in the future. NGMN plans to publish the first version of its “6G Vision & Drivers” White Paper around the end of Q1 of 2021.

Interested industry players are invited to join NGMN in these important initiatives.

NGMN Alliance seeks the rapid development of Option 4 as complement to 5G Standalone

Frankfurt, Germany: Today, the Next Generation Mobile Networks (NGMN) Alliance releases its latest Operator Position Statement paper urging the development finalization of 5G architecture “Option 4” to support the full realisation of 5G. Its Option 4 recommendation will help many networks to bring new 5G-based services quickly and efficiently to market whilst also providing a future-proof evolution that maintains competitive user data rates for 5G users.

A migration to 5G Standalone is an important evolutionary step for 5G with the introduction of a new 5G core network and the transfer of the master radio interface technology from LTE to New Radio (NR) technology. To ensure the most cost and spectrum efficient use of the network which maximises the full 5G advantages, advanced 5G users should be able to connect in parallel via both NR and existing LTE technology. Otherwise new 5G Standalone users will sometimes receive lower data rates than existing Non-Standalone 5G and LTE-only users.

“Development completion of Option 4 is urgently needed to enable all operators to invest in a new 5G core network without compromising user data rate performance,” said Arash Ashouriha, Chairman of the NGMN Alliance. “Advanced 5G users using 5G Standalone should be able to access LTE on top of NR for a seamless service experience”.

NGMN concludes that Option 4 supporting a 5G core and dual connectivity with NR acting as a master is required so that baseline 5G NR radio performance can be enhanced through the use of LTE on top. 5G Standalone users can then access both NR and LTE spectrum in the lower frequency bands supporting wider coverage when it is beneficial to do so.

Raimund Walsdorf, Technology Architecture & Innovation Access & Home Networks, Deutsche Telekom and NGMN project lead said: “Option 4 development will support many network operators planning an initial 5G Standalone service launch today or a more widespread launch in the future. This option benefits operators to more efficiently migrate spectrum from LTE to NR, while also relaxing the pressure on operators to refarm from LTE to NR as long as spectrum remains dedicated to LTE”.

Anita Döhler, CEO, NGMN Alliance added: “NGMN is committed to support an efficient introduction of 5G Standalone (SA) networks to help the industry to deliver on the performance promise of 5G to end-users. Availability of Option 4 in addition to other options will help to better meet end-user demands in years to come.”

The white paper is a result of an ongoing NGMN project which aims to conduct a trial of Option 4 in 2021. This will encourage Option 4 development within the 5G ecosystem with the aim that 5G Standalone can be introduced in all networks in a timely manner. The support of network and terminal suppliers is sought to progress the trial.
