Reelection of Kim Yoon-sun as Chair of 3GPP RAN1 Master

The Ministry of Science and ICT announced that Yoonseon Kim, a master at Samsung Electronics, was re-elected as the chair of the 3GPP Radio Access Network Working Group 1 (RAN1) at the international meeting of five wireless access network working groups under the 3GPP mobile communication standardization organization, held from the 22nd to the 26th.

3GPP involves about 820 mobile operators and manufacturers worldwide and has played a leading role in establishing the standards for 3G (WCDMA), 4G (LTE), and 5G mobile communications.

In particular, the ‘RAN1 Working Group’ is the core working group responsible for the wireless segment Layer 1 (physical layer) standards among the various mobile communication technology working groups of 3GPP. It has been responsible for key technologies such as the CDMA technology standard of 3G, the OFDM technology standard of 4G LTE, and beamforming technology of 5G. Additionally, it is the working group that develops core 5G technical specifications accounting for more than 60% of 3GPP standard patents, playing a pivotal role in fostering the future network industry.

Master Kim’s re-election as RAN1 chair is seen as recognition from the world of Korea’s efforts to expand 5G infrastructure, including the continuous expansion of 5G coverage and the spread of 5G into various fields through Eoum 5G.

Hong Jin-bae, Director of the Network Policy Office at the Ministry of Science and ICT, stated, “Globally, competition for network technology supremacy is accelerating from 5G-Advanced to 6G, which is expected to be commercialized between 2028 and 2030. With Master Yoonseon Kim’s re-election as RAN1 chair at the first in-person meeting held in a country other than Europe since the pandemic, we will continue to support Korea in securing leadership in mobile communication standards and becoming a model country for global cooperation in network technology.”
