“…• Health status detection: The human breath rate and breath status can be detected and tracked via exploiting the phase variation of CSI. SSaC can also be applied in medical diagnosis and vital signs monitoring by analyzing the RF signals and CSI or using wearable devices [3].…”

“…Performing SLAM via RF signals [e.g., mmWave/terahertz(THz)] instead of cameras or laser measurements will be a promising way due to its larger sensing range and relatively low complexity and data amount for processing. • Immersive extended reality (XR) 3 : To enrich the immersive user experience in XR, SSaC will be used to capture the detailed physical environment and human movement to further increase the fidelity of virtual worlds, supporting immmersive applications such as telepresence. • Digital twin applications: By jointly leveraging the SSaC, AI, and sensor networks, it will be feasible to replicate the physical objects in a virtual world via digital replica, called the digital twin.…”

“…It is worth noting that different similar terms, such as integrated sensing and communications (ISAC) [2], [3], joint radar and communication (JRC) [4], dual-functional radar and communications (DFRC) [5], joint communication and radar/radio sensing (JCAS) [6], have been used in the literature. In this article, we advocate the use of the term SSaC because the word "symbiotic/symbiosis" is more inclusive and can better accommodate different integration levels and evolution stages of sensing and communications (SaC).…”

Driven by the vision of intelligent connection of everything and digital twin towards 6G, a myriad of new applications, such as immersive extended reality, autonomous driving, holographic communications, intelligent industrial internet, will emerge in the near future, holding the promise to revolutionize the way we live and work. These trends inspire a novel technical design principle that seamlessly integrates two originally decoupled functionalities, i.e., wireless communication and sensing, into one system in a symbiotic way, which is dubbed symbiotic sensing and communications (SSaC), to endow the wireless network with the capability to "see" and "talk" to the physical world simultaneously. Noting that the term SSaC is used instead of ISAC (integrated sensing and communications) because the word "symbiotic/symbiosis" is more inclusive and can better accommodate different integration levels and evolution stages of sensing and communications. Aligned with this understanding, this article makes the first attempts to clarify the concept of SSaC, illustrate its vision, envision the three-stage evolution roadmap, namely neutralism, commensalism, and mutualism of SaC. Then, three categories of applications of SSaC are introduced, followed by detailed description of typical use cases in each category. Finally, we summarize the major performance metrics and key enabling technologies for SSaC.

“…Most of the leading stakeholders have explicitly started formulating the 6G vision from use case, performance and value perspective, including objectives of societal and environmental sustainability. In addition, several actors have begun exploring prospective 6G technology enablers such as sub-THz communications to exploit spectral bands >100 GHz [28]- [31], localization and sensing [32]- [34], pervasive artificial intelligence (AI) [35], [36] and an initial architecture decomposition for the 6G era [37]. There is also work for defining KPIs; for instance [38], where the authors compare 5G and 6G from the perspective of supported KPIs in identified 5G and future 6G related uses cases for verticals.…”

“…Using lenses for communication systems can also open new possibilities for the imaging applications and joint-communication sensing [3][4][5][6]. Previously, the potential of a 6G radio link has been investigated as a technology enabler for, e.g., accurate localization and high-resolution imaging [7][8][9][10][11].…”

We demonstrate that the future sixth generation (6G) radio links can be utilized for sub-THz frequency imaging using narrow beamwidth, high gain, lens antennas. Two different lenses, a bullet or hemispherical shape, were used in radio link setup (220-380 GHz) for an imaging application. Lenses performed with the gain of 28 dBi, 25 dBi, and the narrow beamwidths of 1 • and 2.5 • . Plants were used as imaging objects, and their impacts on radio beams were studied. For assessment, the radio link path loss parameter was −48.5 dB, −53.2 dB, and −57.1 dB with the frequency 220 GHz, 300 GHz, and 330 GHz, respectively. Also, the impact of the radio link distance on the imaging was studied by 50 cm and 2 m link distances. In addition, the 3D image was acquired using the phase component of the image, and it showed the leaf surface roughness and the thickness, which was similar to the measured value.
