Samsung R&D Institute engineers Rajavelsamy Rajadurai and Lixiang Xu elected to chair and vice-chair positions, respectively

Samsung Electronics has secured new chair and vice-chair positions in the 3rd Generation Partnership Project (3GPP), the world’s largest telecommunications standards organization.

Established in 1998, 3GPP develops global mobile communications standards with participation from major companies and organizations including Samsung, Qualcomm, Apple, Ericsson, Nokia and Huawei. The international body consists of three Technical Specification Groups (TSGs) — Service and System Aspects (SA), Radio Access Network (RAN) and Core Network and Terminals (CT) — each overseeing four to six Working Groups (WGs) for a total of 15 WGs across the organization.

Rajavelsamy Rajadurai, Principal Architect at Samsung R&D Institute India-Bangalore (SRI–B), has been elected chair of 3GPP’s Service and System Aspects Working Group 3 (SA WG3). Meanwhile, Lixiang Xu, Principal Engineer at Samsung R&D Institute China-Beijing (SRC-B), has been elected vice chair of 3GPP’s Radio Access Network Working Group 3 (RAN WG3). SA WG3 defines standards related to network security and user privacy, whereas RAN WG3 develops base station interface protocol technologies. 

In March, Dr. Younsun Kim, Master at Samsung Research, was elected chair of 3GPP’s Technical Specification Group Radio Access Network (TSG RAN) — leading standardization across all areas of wireless technology including the physical layer, protocol aspects and radio resource control.

With these latest appointments, Samsung now holds three chair positions (SA WG2, SA WG3 and TSG RAN) and five vice-chair positions (SA WG4, SA WG6, RAN WG2, RAN WG3 and CT WG3) within 3GPP.

Beginning in the second half of 2025, 3GPP will initiate research into 6G technologies. SA WG3 plans to explore security enhancements to counter cyberattacks, including those from quantum computers, and to develop privacy protection technologies for mobile communications networks. RAN WG3 is expected to research AI-powered solutions to reduce energy consumption at base stations and improve service quality. These groups are positioned to play a crucial role in advancing the use of AI, strengthening security and promoting sustainability — all key focus areas in the development of 6G.

Through its expanded leadership within 3GPP, Samsung has established a framework to help drive standards across the mobile industry and collaborate with partners to shape the future of next-generation communications.
