Wireless: The Endless Frontier - From 5G to 5.5G and Beyond

by  Peiying Zhu, Huawei

Abstract: 5G is rolling out at lighting speed, with world's leading carriers racing for providing various commercial services. It is predicted that more than 6.5 million 5G base stations will be deployed to offer services for more than 58% of world’s population with more than 100 billion 5G connections. There is interest in unitizing 5G infrastructure to realize its full potentials. It is anticipated that with the significant 5G penetration, more and more use cases for commercialization will require 5G evolution by 2025. 5G technology evolution shall bring new values to all stokeholds while maintaining backward compatibility in order to protect the earlier investments. Hence, we believe that it is a right time to consider a well-defined 5.5G framework and standardization in order to support commercialization between 2025 and 2030. In this talk, we will discuss the key driving force, requirements, use cases and capabilities of 5.5G, then the main challenges and potential technologies including the standard roadmap.

As the title says, wireless is the endless frontier, there are new emerging services and technologies beyond 5G evolution, this talk will conclude by proving a glimpse of the horizon beyond 2030.

Wave Control for Wireless Communications: From Time-Reversal Processing to Reconfigurable Intelligent Surfaces

by  Mathias Fink, ESCPI Paris

Abstract: In this talk, I will show how the works performed at Langevin Institute have led to the seminal concept behind large reconfigurable intelligent surfaces (RIS) that is currently a topic of great interest in the wireless communication community and that is proposed as a new paradigm for the sixth generation (6G) of communication networks.

Starting with the first demonstrations of ultrasonic “time-reversal mirrors” focusing in complex media in the early nineties, I will underline how these ideas were first used for underwater acoustic communications and were transposed later, for electromagnetic waves, into the concept of massive MIMO for the 5G communication networks to optimize channel diversity.

Compared to these techniques that need multiple antenna array, I will explain how we proposed, 8 years ago, another approach using tunable metasurfaces to obtain with a limited number of transmitters the best communication performance. The main idea is to replace the numerous transmitting antennas, used in massive MIMO, by a smart modification of the wireless environment by physically shaping the propagation medium to achieve optimal focusing and channel diversity. Using smart mirrors made of reconfigurable metasurfaces placed inside any wireless environment, we tune the medium complexity to obtain the best communication performance. I will show how the optimization of these metasurfaces can be done through the generalization of the “time reversal mirror” concept to the one of the product of different time-reversal mirrors associated with each transmitters and receivers.

Compared to the well-known massive MIMO technique, RIS can provide excellent system performance without requiring power-hungry components such as power amplifiers.

Let us stop delaying low delay

by  Muriel Medard, Massachusetts Institute of Technology

Abstract: Core to all future generation of communications is ultra-reliable low-latency (URLLC), a key enabler to self-driving cars, virtual reality, indeed all delay-sensitive services. The practice lags the promise. To counter the inefficiencies of layers of complexity in 4G and 5G, delay has been mostly managed by costly bandwidth over-provisioning. We propose a different, ab initio approach that reconsiders usual assumptions, yet remains entirely compatible with current systems. At the physical layer, we eschew the current code-centric error-correction approach for a noise-centric one, guessing random additive noise decoding (GRAND), that allows for any high rate error-correcting code. As GRAND is universal, it can work with current codes. We are thus able to find that simple codes, even random codes, match the state of the art encoders and decoders. At the transport layer, URLLC requires a trade-off between rate and delay, negating the ansatz that one is the inverse of the other. Random linear network coding (RLNC) can effectively trade off between in-order delay and goodput with extremely low complexity in the decoding. We show that RLNC-based transport is compatible with current systems and highlight some of the sharp delay gains it provides.

Next to Rel-17, 5G-Adv or 6G?

by  Xinhui Wang, ZTE

Abstract: The first release (Rel-15) of 5G new radio has been completed by 2019. Since then, the global campaign of 5G commercialization is in full swing. In the meantime, the standardization society envisions more vertical applications as the enhancement of 5G in later releases (Rel-16 and Rel-17), such as V2X, Industrial IoT, wearables, non-terrestrial networks, AR/VR, utilization of unlicensed spectrum, etc.

The evolution of wireless communications will never stop. Almost every 10 years there will be a new generation of wireless system. With the success of massive deployment of 5G base stations and popular using of 5G cell phones, people are beginning to think about the future, e.g. vision of 6G.  From the standardization point of view, the first release of 6G specification from 3GPP is likely to be ready by 2029~2030. Before that, we still have about 3-4 releases for 5G stage 2. In Rel-18 and beyond, let us call it 5G-Advanced, we should keep digging the potentials of 5G network to continue the prosperity of 5G industry. Those advanced techniques should cover not only the traditional broadband personal use cases, but also the emerging use cases of verticals as well as the universal enabler, AI.

In this talk, I will show our views on the scope of 5G-Advanced. I will talk about the potential enhancements of the fundamental structure in various aspects as well as more fancy ideas from the long-term point of view, more specifically, that includes AI for 5G, Reconfigurable Intelligent Surfaces, massive MTC, Industrial IoT 2.0, MESH network, integrated terrestrial and non-terrestrial networks, and so on.
