Reconfigurable Intelligent Surfaces (RIS) for 5G-Advanced and 6G
With the deployment of 5G networks and the start of standardizing 5G-Advanced, both academia and industry are exploring actively into future technologies for next generation wireless communication systems. Reconfigurable intelligent surfaces (RISs) have been envisioned to reduce the energy consumption and improve the spectral efficiency of wireless networks by artificially re-configuring the propagation environment of electromagnetic waves. RIS-based transmission, in which the large number of small, low-cost, and passive elements on RIS only reflect the incident signal with an adjustable reflection amplitude and phase shift without requiring a dedicated energy source for radio frequency processing, decoding or encoding, is completely different from existing active relays and open up a new area of research for wireless communications. RISs are being discussed actively in regional and global standardization development organizations and are likely to become a critical component of 5G-Advanced networks.

XR/AR Evolution and Commercialization Aspects
With the increased adoption and take-off of 3GPP 5G-NR in commercial networks, interest in eXtended Reality (XR) devices including Augmented Reality (AR), Virtual Reality (VR) and Mixed Reality (MR) has also significantly increased. These devices would merge the world as experienced through text, images, videos, etc. thereby enhancing and augmenting real/quasi-real experiences in commercial applications. Since such augmentation is contingent on increased data rates and reduced latencies, 5G-NR is naturally poised to address these challenges. The scope of this session would be to present the state-of-the-art in XR evolution aspects as seen from a technology perspective in Release 18 (and beyond) of 5G-NR as these releases start to fructify. This session would also chart out the future scope of commercialization aspects in this area and present a well-rounded overview of this area including the opportunities and challenges in the road from paper design to products and commercialization. The speakers in this session include well-established researchers in XR with a fundamental understanding in the arenas of R&D, standardization and practical deployments.
6G Vision and Enablers
While the mobile industry is now focusing on the realization of what 5G technologies promised, we can see that initial consideration about the next generation of mobile communications, i.e., 6G, is already happening. Considering the general trend of introducing new services with higher requirements over different generations of communication systems, it would be natural to expect that 6G technologies need to be developed to envision more advanced services than 5G. Examples of such new services include truly immersive XR, mobile hologram, and digital replica. Initial investigation already suggests rough estimates of performance requirements for 6G such as 1 Tbps peak rate, 1 Gbps user-experienced data rate, and 0.1 ms air latency. Use of terahertz spectrum would naturally be considered to provide such high data rate. Novel approaches, e.g., reconfigurable intelligent surfaces, further advanced duplex technologies, use of AI/ML, would need to be considered to satisfy the expected performance requirements. In this proposed industry presentation session, industry experts will present their views on 6G vision and enablers.
