Samsung Electronics announced a white paper today highlighting the company’s strategy for obtaining global frequency bands for 6G, the next-generation communications technology. [1]

Figure 1 shows that the 6G would require spectrum with ultra-wide contiguous bandwidth ranging from hundreds of MHz to tens of GHz to enable new services such as high-fidelity mobile holograms and truly immersive extended reality (XR) that are characterized by communications ultra-fast and a large amount of data. There is also a growing demand for greater coverage.

In response to these requirements, Samsung proposes to consider all the bands available for 6G, from the low band under 1 GHz, to the medium band in the range 1-24 GHz and the high band in the range 24-300 GHz.

This also highlights the importance of securing new bands for commercial 6G deployments, as 5G networks will still be operational when the 6G rollout begins. The midband in the 7-24 GHz range is a candidate that can support faster data speed and reasonable coverage.

The sub-terahertz (sub-THz) band in the 92–300 GHz range is being considered for ultra-fast data rate support. The white paper also mentions reframing existing bands used for 3G, 4G and 5G networks to 6G operation as another way to get all the spectrum needed for 6G.

In addition, he notes that research on prospective regulations and technologies on spectrum use is essential to provide efficient and flexible support of 6G and other services with limited spectrum.[2]

By allowing continuous uplink transmission in a tiny amount of the system bandwidth, XDD can improve the propagation distance of uplink signals in TDD systems by up to two times. As a result, XDD can significantly improve the coverage of TDD systems commonly employed in high-frequency bands. At the base station, Samsung exhibited its basic technology, self-interference cancellation.

On May 13, 2022, Samsung expects to unveil more details and conclusions from its 6G research during the company’s first Samsung 6G Forum.[3]

“We have started on our journey long ago to understand, develop and standardize the 6G communications technology,” said Sunghyun Choi, Executive Vice President and Head of the Advanced Communications Research Center at Samsung Research.2 “We are committed to taking the lead and sharing our findings to spread our vision to bring the next hyper-connected experience to every corner of life.” [4]
