Lifetime Achievement Award for RAN expert

December 11, 2019

TSG RAN#86, Sitges - Spain

At the end of the days work, in the RAN room yesterday, the 3GPP Lifetime Achievement Award was presented to Dr. Wan Lei, of Huawei Technologies, in recognition of fifteen years of highly productive work within and on behalf of the project.

Wan Lei has led the Huawei standardization efforts on 4G and 5G technologies since 2008, having begun work in RAN - as principle engineer in Ericsson Research, in 2001.

She is a renowned expert in simulation methodology & radio evaluation techniques, and 3D antenna and channel modeling. Wan Lei was also active in the 3GPP self-evaluation process for our LTE-Advanced technology submission as the ITU IMT-Advanced system. More recently, she has ensured a high degree of expert engagement in the evaluation work on 3GPP NR – by her team – to help prepare our submission for the ITU IMT-2020 system – 5G.


3GPP SA6 initiatives to enable new vertical applications

September 30, 2019

A new webinar “3GPP SA6 initiatives to enable new vertical applications” is now available on replay – free of charge and without any annoying registrations!

During this 30 minute presentaion, Suresh Chitturi, the SA6 Working Group Chair, introduces the group’s work to provide application layer functional elements and interfaces that will serve the needs of new (to 3GPP) industry sectors - or verticals - by providing a middleware layer, as a common service platform for their 5G implementations.


Wednesday Speakers Club at TSG#86

Updated & amended December 12, 2019

Our speaker at the Wednesday speakers club, during TSG#86, Dirk Kretzschmar of TÜViT, presented some of the new directions for ICT security protection against criminal attacks at all levels of the system.

Dirk Kretzchmar described the cyber threat spectrum – from hackers, insiders, organised crime, espionage, terrorists up to the Nation State and acts of war. The presentation looked at how various sectors have an interest in understanding the common criteria that they must establish to protect data and equipment.


5G for the connected World

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

October 8, 2019

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.
