System architecture milestone of 5G Phase 1 is achieved

December 21, 2017

By Frank Mademann, 3GPP SA2 Chairman

The past two years have seen the 3GPP 5G architecture work progressing from the study period in 2016 to the delivery of a complete set of stage 2 level specifications. By achieving this milestone in 3GPP Release 15 the 5G system architecture has been defined - providing the set of features and functionality needed for deploying a commercially operational 5G system.

Optimizing media and radio signal processing for 5G

March 20, 2018

With the approval of the first 5G NR specifications, the industry is now moving toward the development and deployment phases, where design objectives of the new systems have to be realized. Kyunghun Jung, the co-author of "Media and Radio Signal Processing for Mobile Communications" looks at these phases and at the need to identify where standards remain silent.

By Kyunghun Jung, former 3GPP SA4 Vice Chairman

As the work to develop media and radio signaling standards for 5G progresses toward the realization stage, experiences of developers and operators reveal opportunities for further refinement of the standards while still allowing differentiation of products and services.

As there are limitations on what can be specified in the standards, extracting maximum service quality and network capacity from new systems requires developers and operators to understand the media and radio signal processing operations of devices and networks, and locate the opportunities to innovate within the boundary of standards.

Although compression and transmission of media have been playing fundamental roles in 3GPP systems, signal processing operations previously not attempted, such as 360 media or transmission faster than conversational class, may impose unprecedented constraints. Newly introduced technical elements or system architectures can make well-proven approaches insufficient or unnecessary, and features that have been taken for granted may not be supported in new systems.

Lifetime Achievement, second award presented

March 8, 2018

On Monday of last week, the 3GPP RAN2 Chairman - Richard Burbidge - presented Don Zelmer with the 3GPP Lifetime Achievement Award on behalf of the project.

Don Zelmer has participated in 3GPP since our creation, attending over 600 TSG and WG meetings and taking on the Rapporteur role for several study and work items, including work on Public Warning Systems (PWS), future FDD HSPA Evolution and for the introduction of the UMTS850 (Band V) in to 3GPP specifications.

He has served as Vice Chair of 3GPP TSG RAN (1999-2009) and now attends TSG RAN & RAN WG#2 as a lead AT&T Delegate. Don regularly attends the 3GPP Project Coordination Group (PCG) and Organizational Partner’s meetings, as a member of the ATIS delegation.

In addition to his leadership in 3GPP, Don has regularly served as Chair of the ATIS Wireless Technologies and Systems Committee (WTSC), which is one of the primary North American drivers into 3GPP.
