3GPP RAN#86 held 9-12 December made substantial decisions regarding the further technology evolution of 5G NR radio. Nowhere is it more apparent, than in 3GPP RAN, that the 5G ecosystem is building out to be substantially more versatile than LTE.

5G NR radio evolution is carried out with a drive from a multitude of key stakeholders from the traditional commercial cellular industry, a wide variety of industry verticals and the non-terrestrial access ecosystem. The Release-17 work program is a testament that 3GPP is committed to serving all of these key stakeholders.

November 13, 2019

The recently published book ‘5G for the connected World’, edited by Devaki Chandramouli, Rainer Liebhart and Juho Pirskanen explains 5G in detail, focusing on 3GPP Release 15 content and how it can be used to enable new services beyond the ones specified for LTE. In this edited extract Devaki Chandramouli and Rainer Liebhart look at how URLLC makes the difference:

One of the key differentiators between LTE and 5G is the capability to provide ultra-low latency and extreme high reliability connectivity service to applications.

Low latency translates usually to a few milliseconds, even 1ms in the extreme case, for end-to-end latency between client and server on the user plane. Control plane latecy requirements are usually less stringent, in range of 10ms.


5G Systems Development and Deployment

In his recent book, 5G NR: Architecture, Technology, Implementation, and Operation of 3GPP New Radio Standards, Sassan Ahmadi, a regular TSG RAN and RAN Working Group delegate, provides a detailed explanation of how the 5G new radio access and core networks are being implemented and deployed. The following article is an introduction to the book, providing a high-level view on 5G systems design, implementation and deployment.

By Dr. Sassan Ahmadi, Xilinx Director and Lecturer at Stanford University

The substantial growth in the number and variety of connected devices and the increase in user/network traffic, as well as the performance limitations of 4G technologies, have motivated industry efforts toward the deployment of 5G mobile networks. Network operators are gearing up toward meeting the dramatic increase in capacity by a combination of; new spectrum utilization, spectral efficiency improvements and ultra-dense network deployments. The 5G system includes intrinsic flexibility and configurability to optimize the network for a wide range of use cases and business models.

The high-throughput mobile broadband use case is primarily based on the evolution and enhancement of LTE technology which facilitates coexistence with the existing radio access networks. However, this legacy support is limited to sub-6 GHz spectrum. All deployments above 6 GHz must use new baseband and radio technologies that improve spectral efficiency, throughput, latency, and other key performance metrics. The 5G mission-critical MTC (low latency and high reliability) and massive-MTC (low energy, low cost, dense coverage) are new use cases that may not rely on legacy support or backward compatibility.

To address the questions that newcomers to 3GPP dare not ask, the 3GPP TSG Chairs have initiated a breakfast time session – held during the Plenary week – where the leaders take new attendees through material on what 3GPP is doing and how it is done. The first 'Newcomer’s orientation session’ was well attended and should be repeated at future TSG meetings.

A few issues came to light in the session, related to the challenges encountered getting a technical proposal through the groups, how the coordination between SA and RAN is organized, on how challenging the 3GPP environment can be for new comers – as well as practical questions on the portal, web site use and meeting registration.

The 105th RAN3 meeting in Ljubljana was an important milestone for one of the long-time RAN3 delegates and the whole group, as it marked the last RAN3 meeting for Martin Israelsson, after 20 years of involvement in the group - in a multitude of roles and positions.

Martin is one of the pillars of 3GPP RAN3, ever present since December 1999, as well as being active in the 3GPP RAN Plenary. He has served as RAN3 Chairman from 2001 to 2003, and as RAN3 Vice-Chairman from 2009 to 2017. Martin’s role has been crucial in fostering a cooperative climate through technically solid discussion and, when required, historically accurate explanations of what led to a certain technical decision.

July 18, 2019

In a recent 3GPP webinar, Balazs Bertenyi – the TSG RAN Chair - discussed the current and future priorities for the radio groups.

Although the webinar is intended for people with some knowledge of how 3GPP functions and of the various working group’s working methods, we do hope that it could also be of interest to non-3GPP experts and other enthusiasts too.

Buried in the presentation are some important details of the work areas being considered by RAN – for Release 17. Balazs gives us an explanation why Release 17 will probably be on the ‘short’ side, spanning a mere 15 months. There is also a hint that the next release will complete some very important pre-normative studies on 5G NR in spectrum above 60GHz. He also gets modest on 3GPP’s impact on the future of AI.

A Press Release, from ETSI, emphasizes the role of NFV in addressing the variety of applications expected to run on top of the 5G system. It looks also at how ETSI’s NFV ISG work to support network slicing, including ‘Management over multi-administrative domains’ (GS NFV-IFA 030) and ‘Multi-site network connectivity’ (GS NFV-IFA 032), is helping the 3GPP management system to interact with the NFV MANO system - for resource management of the virtualized 5G network.

One of the highlights of ETSI NFV Release 3 is set to be the work on defining an external touchpoint between the NFV’s Network Service and network slicing (GR NFV-IFA 024) - in which the Network Service becomes a composite element of the 3GPP SA5 working group’s network slice subnet construct (TS 28.530) – intended to allow implementations to easily combine the 3GPP Network Resource Model (NRM) with the ETSI NFV Information Model.

- RAN Working Group 4 has been focusing on ensuring the stability and compatibility of the Release 15 specifications as it draws to a successful completion. Now, the focus shifts to work on Release16, where RAN4 has made tremendous early progress on new 5G NR bands and band combinations. 

Due to practical reasons the Release 16 version of RAN4 specifications will only be created in June 2019 RAN Plenary. In the meantime, the completed Release 16 band specifications are maintained in RAN4 as a set of endorsed Change Requests. Note that band specifications have always been release independent. Consequently, from a specification perspective Release 16 NR bands and combinations can be supported by Release15 User Equipment (UE) and network.
