Industry Experts Discuss the Present, Potential and Future of Next-Generation Communications Technologies at Samsung’s First-Ever 6G Forum

Samsung Electronics held its first Samsung 6G Forum under the theme of ‘The Next Hyper-Connected Experience for All’. The forum, which was broadcast live, was split into two sessions, with the morning session themed ‘6G Air Interface’ and the afternoon session themed ‘Intelligent Network for 6G’.

Both sessions at the Forum featured talks from experts across academia and industry who specialize in next-generation communications technologies, and featured topics covering the present state and ambitious future of 6G.

Sebastian Seung, President and Head of Samsung Research,¹ opened up the Forum by sharing Samsung’s vision for the next-generation of communications technologies. “We envision that 6G will provide the ultimate in experiences through the next level of hyper-connectivity, and this idea serves as the foundation of our 6G vision,” noted Seung. “We believe that it is the right time to start preparing for 6G. Shaping 6G will require many years, as we have seen with previous generations, and will need lots of discussion and collaboration among players in industry as well as academia.”

Setting the tone for the rest of the day, Seung went on to express his confidence in 6G’s potential to become a fundamental technology that drives a convergence of services between industries and will be ultra-wideband, ultra-low latency, ultra-intelligent and hyperspatial, as well as opening up whole new realm of connectivity.

Opening up the morning session of the 6G Forum, Jeffrey Andrews, Professor at the University of Texas at Austin, delivered a keynote speech titled ‘Deep Learning in the 6G Air Interface’. This keynote saw Andrews focus on the role of machine learning in next-generation communication, including how 6G communication can improve the performance of air interface through deep learning as well as how more deeply-penetrated machine learning might be expected to transcend the current limits of 5G technologies. “In order to successfully apply machine learning to 6G as well as 5G, it is of course necessary for us to understand both wireless communications and machine learning fundamentals,” emphasized Professor Andrews. “It is essential for us to work together in order to make progress on this topic and do novel work.”The keynote speech was followed by a series of in-depth expert talks, the first of which was given by Charlie Zhang, Senior Vice President (SVP) at Samsung Research America and titled ‘Radio Technology Evolution for Beyond 5G and 6G’. SVP Zhang introduced the R&D progress for the possible wireless technologies of 6G communication and presented two new 6G spectrum opportunities that are currently being investigated: an upper mid-band of 7-24 GHz and an enormous sub-terahertz band of 92-300 GHz. “Both options provide us with a very good opportunity to find enough capacity for all these exciting 6G services,” noted SVP Zhang. He then also detailed how sub-terahertz band has been tested in the field by his team as well as introduced advanced duplex technology called XDD for coverage enhancement and innovations in distributed MIMO. He concluded with an enthusiastic reiteration of the value of cooperation, emphasizing the need for collaboration between institutions, companies and countries necessary to bring about future innovations.

The second expert talk was given by Takehiro Nakamura, SVP and General Manager at NTT DOCOMO under the title of ‘5G Evolution and 6G’. As well as discussing the global growth seen recently into 5G and 6G research, SVP Nakamura expressed his opinions on performance improvement in the case of Innovative Optical and Wireless Network (IOWN) technology being applied in 5G and 6G communications. “6G networks can perform as human nerves,” detailed SVP Nakamura regarding the potential of IOWN technologies applied for 6G. “They can augment and extend human capabilities. If we can share body movement, the five senses and emotions through 6G networks, we can realize very interesting and exciting new services which were described as science fiction.”

The third expert talk of the morning session was conducted by John Smee, SVP of Qualcomm Technologies, Inc., on the topic of ‘Driving Air Interface Innovation Toward 6G’. SVP Smee carefully detailed how technological innovations will pave the path to a 6G world. “When we take a step back and imagine the world in 2030, it’s really about understanding changing the physical world and many different types of devices that we will have connected,” he explained. SVP Smee highlighted six key research vectors in particular: artificial intelligence (AI)/machine learning (ML)-powered E2E communications, spectrum expansion and sharing, new radio designs, communications resiliency, scalable network architecture and the merging of worlds.
