Samsung unveils 6G analysis findings and 6G spectrum white paper

Samsung Electronics had revealed a white paper introducing its 6G imaginative and prescient in July 2020

Samsung Electronics launched a white paper that lays out the corporate’s imaginative and prescient for securing international frequency bands for future 6G expertise.

The paper, titled “6G Spectrum: Increasing the Frontier,” discusses methods to acquire the spectrum wanted to attain the corporate’s 6G imaginative and prescient launched in a white paper launched earlier in July 2020.

“We’ve got began on our journey way back to grasp, develop and standardize the 6G communications expertise,” mentioned Sunghyun Choi, govt vp and head of the Superior Communications Analysis Middle at Samsung Analysis. “We’re dedicated to taking the lead and sharing our findings to unfold our imaginative and prescient to carry the following hyper-connected expertise to each nook of life.”

In line with Samsung Electronics, 6G would require spectrum with ultra-wideband contiguous bandwidth starting from lots of of MHz to tens of GHz to allow new providers resembling high-fidelity cellular holograms and really immersive prolonged actuality (XR) which might be characterised by ultra-high pace communications and great amount of knowledge. In response to those necessities, Samsung proposes contemplating all obtainable bands for 6G, from low-band underneath 1 GHz, to mid-band within the 1-24 GHz vary and high-band within the 24-300 GHz vary.

The South Korean vendor additionally highlights the significance of securing new bands for industrial deployments of 6G, as 5G networks will nonetheless be operational when the 6G deployment begins. “The mid-band throughout the 7-24 GHz vary is a candidate that may help sooner information pace and affordable protection. The sub-terahertz (sub-THz) band within the 92–300 GHz vary is being thought of for help of ultra-high pace information price,” Samsung mentioned.

The white paper additionally mentions the re-farming of current bands used for 3G, 4G and 5G networks to 6G operation as one other approach to get hold of all of the spectrum needed for 6G. It additionally notes that analysis on forward-looking rules and applied sciences on spectrum utilization is important to supply environment friendly and versatile help of 6G and different providers with the restricted spectrum.

Samsung additionally highlights its analysis findings on a few of 6G candidate applied sciences – particularly about sub-THz band communications, reconfigurable clever floor (RIS), cross division duplex (XDD), full duplex, synthetic intelligence (AI)-based nonlinearity compensation (AI-NC) and AI-based vitality saving (AI-ES).

Sub-THz is taken into account a spectrum candidate for 6G communications, which is predicted to help the info price as much as 1 Terabits per second (Tbps).

“RIS can enhance the beam sharpness and may steer or replicate the wi-fi sign to a desired course with using a metamaterial floor. It might cut back the penetration loss and blockage of excessive frequency sign, e.g., mmWave. Samsung demonstrated that their RIS lens expertise can improve the sign energy by 4 instances and the beam steering vary by 1.5 instances.”

Samsung additionally famous that XDD can enhance the propagation distance of uplink sign as much as two instances within the TDD system by enabling the continual uplink transmission in a small portion of the system bandwidth.

With full duplex, the info transmission and reception can happen concurrently utilizing the identical frequency in order that the info pace will increase as much as two instances, whereas AI-NC makes use of AI on the receiver to compensate the sign distortion brought on by the nonlinearity of a transmitter’s energy amplifier and therefore, can considerably enhance the protection and high quality of high-rate information indicators.

Additionally, AI-ES capitalizes on AI to reduce vitality consumption on the base station by adjusting the parameters controlling the facility on/off of chosen cells relying on site visitors load, with out affecting community efficiency, Samsung mentioned.
