Multiple access has long been the “pearls in the crown” for each generation of mobile communication networks. In the past generations, grant-based orthogonal multiple access (OMA) schemes such as Time Division Multiple Access, Frequency Division Multiple Access, Code Division Multiple Access, and Orthogonal Frequency Division Multiple Access, have been the major schemes, where each user is allocated with one orthogonal time/frequency/code resource. Now, we colleague already stand at 5G “Square” and heading towards 6G. The evolution from 5G towards 6G is expected to transfer the communication philosophy from connected people and things to connected intelligence, which brings new usage scenarios and new challenges for conventional OMA-based systems. In addition to the explosive data demand in 6G, emerging bandwidth thirsty applications (e.g., virtual reality, augmented reality), massive connectivity (e.g., Internet-of-Things networks connecting billions of machine-type devices), ubiquitous wireless coverage (e.g., space-air-ground-integrated-networks), multi-functional wireless networks (e.g., the integrations of communication, sensing, and computation), and bit-beyond transmissions (e.g., semantics/tasks/goals-oriented communications) create new challenges for multiple access. Given the limited radio resources and the stringent rate/latency/connectivity requirements, it necessitates the paradigm shift in multiple access design from grant-based OMA to non-orthogonal/massive/random/grant-free multiple access and other possible multiple access for 6G, namely Next Generation Multiple Access (NGMA). Moreover, the development of NGMA has also to be jointly considered with new enabling technologies, new spectrums, advanced artificial intelligence tools/native intelligence, etc. This workshop aims to attract novel and solid contributions on the emerging topic of NGMA for future wireless communications.

3GPP has witnessed the growth of interest in cellular positioning solutions from a variety of use cases and scenarios in 5G and 5G-advanced. Recently the normative phase of the Release-18 expanded and improved positioning as the first release of 5G-advanced has been launched, which will eventually broaden the landscape of location service provided by the cellular eco-system.

The next 6G cellular networks will be a rendezvous between localization, sensing, and communication. Indeed, through their design, new applications, such as cross/augmented reality, radio holography, and autonomous vehicle navigation, will be enabled at an unprecedented accuracy and reliability. Towards this vision, technologies for 6G environment-aware communication systems foster the usage of new radio frequency (RF) spectrum at high frequency ranges (e.g., the Terahertz bands), or the employment of beamspace processing techniques that represent the evolution of current beamforming techniques in the 3D space domain. In addition, large intelligent surfaces (LIS), in either active or reflective mode (e.g., as reconfigurable intelligent surfaces (RIS)), have already been identified as a powerful paradigm thanks to the possibility to shape the electromagnetic environment intelligently, thus enhancing ambient awareness.

This workshop aims to bring together researchers and experts from academia and industry, and to discuss and promote the research and development needed to overcome the major challenges and discuss the new opportunities and the key techniques to support future positioning and sensing solutions for IMT systems beyond 5G, including but not limited to the following aspects:

  • Fundamental Localization Limits
  • Carrier phase positioning
  • Bandwidth aggregation across non-contiguous frequency bands
  • Ultra-wide bandwidth techniques
