Title: 3GPP: 5G-Advanced and Beyond

Abstract:  Since early 2022, 5G in 3GPP has entered the second phase of standardization, also known as 5G-Advanced. As the first release of 5G-Advanced, Release 18 in 3GPP has been progressing well despite the challenges due to COVID-19. In this talk, we will provide a high-level summary of 3GPP Release 18 from the radio access network (RAN) perspective: the set of the RAN projects, its timeline, and the current status. We will also give a brief introduction of how 5G will evolve in the next several years. We will provide a summary of the Release 19 workshop, successfully arranged in June 2023. As a continuation of 5G-Advanced, Release 19 will primarily focus on continuing investing in 5G-Advanced commercial deployments to further improve performance and address critical needs. Release 19 is also a bridge to 6G, for which 3GPP is expected to develop an input to the IMT-2030 process in the future.

Title: Future wireless access

Abstract:  With the deployment of 5G systems now well underway all over the world, the focus is turning towards the development of future wireless-access technology, both the longer-term evolution of 5G, referred to as “5G Advanced”,  and, further into the future, next-generation (6G) technology. In this talk we will provide an overview of the state of this technology evolution, in terms of anticipated driving use cases and corresponding required technology capabilities as well as key technology components that may be applied to enable these capabilities.

Title:  A path to energy-efficient 6G networks: Exploring promising research directions

Abstract:  The development of 6G networks requires careful consideration of several critical factors, including the predicted increase in data traffic, the seamless integration of sensing services with real-time analytics (Network as a Sensor), and the expansion of network densification while simultaneously maintaining sustainability goals. In this context, energy efficiency becomes a critical factor in the development of 6G technologies. In this talk, we will present promising research avenues that have great potential to significantly reduce energy consumption in 6G networks. We will focus on two research areas: cell-less massive MIMO networks in the context of sub-6GHz and sub-THz communications, and reconfigurable intelligent surfaces. Our discussion draws on the collaborative efforts of the 6G Research and Innovation Cluster (6G-RIC), which has launched an ambitious and comprehensive interdisciplinary research program to address the technical challenges associated with the development of 6G networks. By exploring these research directions, our goal is to foster advances that will lead to more energy-efficient and sustainable 6G technologies.

Title:  Will AI/ML revolutionize the next generation of wireless communication?

Abstract:  Artificial intelligence (AI) in its form of machine learning (ML) has achieved tremendous success in areas like image and video recognition, object detection, and natural language processing, to name just a few examples. Over the past years of fundamental research on what will eventually become a 6G wireless communication standard, researchers and key industry players have been investigating the native support of AI/ML-based models and algorithms for signal processing for the future 6G air interface. The initial focus lies on the receiver part while introducing the concept of a neural receiver. Although simulations show a performance gain compared to traditional concepts, open questions remain: Will the use of AI/ML revolutionize the next generation of wireless communication? What is required to achieve the full potential of AI/ML-based signal processing, and what role do test and measurement solutions play in the overall context? This talk will provide some insights and answers to these exciting questions.
